Stimulated by droughts and inability to construct new freshwater projects, water suppliers in California, U.S.A. have taken a heightened interest in water reclamation in the last decade. Since 1980 the California State Water Resources Control Board has approved financial assistance to local water supply agencies to design and construct water reclamation facilities. Nineteen of these are now operating. There is an opportunity to assess how well projects are performing in relation to their planned objectives, in particular, deliveries of reclaimed water to users. Based on reports on many of these projects, it is found that two-thirds of the projects are delivering 75 percent or less of the expected amounts of water. Data are provided on project performance. A discussion is provided of the problems encountered on many of the projects that account for these deficiencies in yields and have caused other problems in implementation.

Abstract. A source-oriented representation of airborne particulate matter was added to the Weather Research & Forecasting (WRF) model with chemistry (WRF/Chem). The source-oriented aerosol separately tracks primary particles with different hygroscopic properties rather than instantaneously combining them into an internal mixture. The source-oriented approach avoids artificially mixing light absorbing black + brown carbon particles with materials such as sulfate that would encourage the formation of additional coatings. Source-oriented particles undergo coagulation and gas-particle conversion, but these processes are considered in a dynamic framework that realistically "ages" primary particles over hours and days in the atmosphere. The source-oriented WRF/Chem model more accurately predicts radiative feedbacks from anthropogenic aerosols compared to models that make internal mixing or other artificial mixing assumptions. A three-week stagnation episode (15 December 2000 to 6 January 2001) during the California Regional PM10/PM2.5 Air Quality Study (CRPAQS) was chosen for the initial application of the new modeling system. Emissions were obtained from the California Air Resources Board. Gas-phase reactions were modeled with the SAPRC90 photochemical mechanism. Gas-particle conversion was modeled as a dynamic process with semi-volatile vapor pressures at the particle surface calculated using ISORROPIA. Source oriented calculations were performed for 8 particle size fractions ranging from 0.01–10 μm particle diameters with a spatial resolution of 4 km and hourly time resolution. Primary particles emitted from diesel engines, wood smoke, high sulfur fuel combustion, food cooking, and other anthropogenic sources were tracked separately throughout the simulation as they aged in the atmosphere. Results show that the source-oriented representation of particles with meteorological feedbacks in WRF/Chem changes the aerosol extinction coefficients, downward shortwave flux, and primary and secondary particulate matter concentrations relative to the internally mixed version of the model. Downward shortwave radiation predicted by source-oriented model is enhanced by 1% at ground level chiefly because diesel engine particles in the source-oriented mixture are not artificially coated with material that increases their absorption efficiency. The extinction coefficient predicted by the source-oriented WRF/Chem model is reduced by an average of ∼ 5–10% in the central valley with a maximum reduction of ∼ 20%. Particulate matter concentrations predicted by the source-oriented WRF/Chem model are ∼ 5–10% lower than the internally mixed version of the same model because increased solar radiation at the ground increases atmospheric mixing. All of these results stem from the mixing state of black carbon. The source-oriented model representation with realistic aging processes predicts that hydrophobic diesel engine particles remain largely uncoated over the +7 day simulation period, while the internal mixture model representation predicts significant accumulation of secondary nitrate and water on diesel engine particles. Similar results will likely be found in any air pollution stagnation episode that is characterized by significant particulate nitrate production.

Abstract Improving water management in California requires a transition from imported to local water resources used efficiently. To assess this transitional capacity of water retailers in metropolitan Los Angeles County, we focused on a key water management metric: the water distribution efficiency. We traced the evolution of water loss reduction policy and practices globally with emphasis on California. California Senate Bills 1420 and 555 mandate annual water auditing and reporting for urban water suppliers. We surveyed and evaluated ten water retailers' approaches to monitor and reduce losses. Four of ten sampled water retailers monitored real losses, averaging 3–4% of total water supplied. Only three of ten sampled water retailers employed leak detection technology. Of the six sampled retailers with annual pipe replacement strategies, four retailers followed inadequate rehabilitation schedules. Most of the sampled retailers monitor water losses in percent, which misrepresents the actual volume. While a necessary step, California water loss legislation relies on the American Water Works Association Water Audit software. Verifying reported data for randomly selected retailers can ensure high data quality. Small retailers are exempt from mandatory water loss monitoring, and they need state support and resource pooling to improve their water distribution efficiency.

Abstract Congress created the Agricultural Extension Service (AES) in 1914 to disseminate agricultural research to individual farmers but the service operated differently in each state. In California, AES aided agribusiness in its efforts to create a "harmonious hierarchy" that included a non-white laboring class. Records show that AES personnel contributed by helping to separate Native Americans from their land and water resources, prevent competition from immigrants from Asia, and Americanize non-whites.

The current analysis attempts to quantify the interlinkages between the water, energy and food sectors of California covering the period 2002–2015. The results reveal that 25% (60,696 GWh) of the annual energy consumption is attributed to agriculture, while 75% (174,709 GWh) is used for water supply purposes. The agricultural sector consumes 77% (32,629 m3) of the irrigation water, and the energy sector is vulnerable to water availability fluctuations, because many hydroelectric facilities are connected to its grid. Considering the water scarcity and the uneven geographical distribution of water in the state, its central role in California’s water–energy–food (WEF) Nexus becomes apparent.

An understudied aspect of performance management systems is how performance management systems emerge in public agencies. This research focuses on the emergence of performance management systems, studying two cases with divergent outcomes in the State of California. The first case study is about the Performance Management Council, which included the voluntary participation of more than 20 California state agencies, departments, and divisions. The second case study is about the Department of Toxic Substances Control within the California Environmental Protection Agency. These cases, which impacted 35 million residents in a state with a $200 billion annual budget, potentially offer findings valuable to nations and to large sub-national units of government such as large states, districts, and provinces.This research offers three contributions to public sector performance management research literature. First, it addresses a gap in the understanding of how performance management systems emerge through dialogue and learning forums. Second, the research extends the study of performance management to the policy arenas of environmental protection, water resources, and other policy domains typically not researched in performance management. Third, the research connects performance management to the research on the reform of public agencies, diffusion of practices, and organizational change.

The Sustainable Groundwater Management Act (SGMA) of 2014 and the Central Valley Salinity Alternatives for Long-Term Sustainability (CVSALTS) initiative were conceived to reverse years of inaction on the over-pumping of groundwater and salination of rivers that both threaten agricultural sustainability in the State of California. These largely stakeholder-led, innovative policy actions were supported by modern tools of remote sensing and Geographic Information System technology that allowed stakeholders to make adjustments to existing resource management and jurisdictional boundaries to form policy-mandated Groundwater Sustainability Agencies (GSAs) and Salinity Management Areas (SMAs) to address future management responsibilities. Additional resources mobilized by the California Department of Water Resources (CDWR) and other water resource and water quality management agencies have been effective in encouraging the use of spreadsheet accounting and numerical simulation models to develop robust and coherent quantitative understanding of the current state and likely problems that will be encountered to achieve resource sustainability. This activity has revealed flaws and inconsistencies in the conceptual models underpinning this activity. Two case studies are described that illustrate the disparity in the challenges faced by GSAs in subregions charged with developing consensus-based Groundwater Sustainability Plans (GSPs). These case studies also illustrate the unique aspect of SGMA: that alongside mandates and guidelines being imposed statewide, local leadership and advocacy can play an important role in achieving long-term SGMA and CVSALTS goals.

Because biofuels have the unique potential to be rapidly deployed in existing transportation fuel infrastructures, they should play a major role in helping California quickly meet its aggressive goals to substantially reduce greenhouse gas contributions by this major sector. Furthermore, energy crops are vital to significantly impact the State’s large and burgeoning need for sustainable fuels. Among crops amenable to be grown in California to support fuel production, agave pose a particularly promising prospect, given their drought tolerance and high productivity on marginal land in a State prone to drought and limited water resources. This study focuses on measuring compositional profiles of wild A. deserti and cultivated A. americana, two agaves native to California, to elucidate their potential for biological conversion to fuels that can help meet the huge State need for low-carbon transportation. Results from this study indicate that these two California agave species can be rich in fructans, ranging from 96–314 g/L of equivalent fructose and glucose in their leaf bases. In addition, structural and water-soluble sugar contents exceeding 63 wt.% show that these plants are amenable to fermentation to ethanol and other biofuels. Moreover, because the low K-lignin content of agave leaf bases bagasse of only about 12–18 wt.% suggests low recalcitrance and the negligible acid insoluble ash content should facilitate pretreatment prior to fermentations, the agave species native to the State hold considerable promise as potential biofuel feedstocks.

ABSTRACT Seismic activity and other natural and human forces significantly threaten the structural integrity of Delta levee systems. Breached levees appreciably impact fresh water resources, damage crops and livestock, destroy homes, schools, public works, businesses and wild species habitat, among other vital, sensitive areas. Levee failure often leads to oil and petroleum contamination of freshwater resources, particularly in dense residential, agricultural and commercial areas protected by levee systems that depend upon such water resources for drinking, irrigation and industrial uses. San Joaquin Delta to illustrate selected impacts to a freshwater region jeopardized by levee failure, this paper will: 1) discuss the current state of the Delta levee systems and detail the fragility of the system and the potential consequences of major impacts - earthquakes and floods likely to jeopardize this system; 2) review issues concerning levee breach preparedness, including practices to maintain levee structure and promote levee rehabilitation; and 3) suggest a coordinated federal, state and local response to contain damage caused by a levee breach, with particular focus on oil and hazardous materials spill impacts. As with many levee systems, the issues presented by a levee breach to the Sacramento-San Joaquin Delta region are complex and require close, concerted federal, state and local participation, not only to rapidly and effectively respond to impacted areas, but to anticipate and avoid more massive levee failure. Employment of these levee protection and breach response measures will help defend, among other vital resources, domestic, agricultural and industrial water for use from oil, petroleum and other hazardous contaminants.

This chapter looks at the efforts to protect California's air quality. Public and business demands for automobile control in the United States originated in Los Angeles, and pollution controls for motor vehicles were essentially initiated by the state of California. Following a successful national political campaign that pitted the interests of California against the nation's automotive manufacturers, in 1967, Congress allowed California—and initially only California—to issue its own vehicle emissions standards. Thanks to the unique pollution problems of Los Angeles, the United States became and remains the only country to have two distinctive mobile-source pollution control standards. Many of the themes described throughout this book are illustrated in this chapter. These include the importance of both citizen mobilization and business support for stronger environmental regulations and the progressive development of the state's regulatory capacity, from the creation of the Smoke and Fumes Commission in Los Angeles in 1945 to the organization of air pollution control districts in 1947 and finally the establishment in 1968 of the California Air Resources Board.

This chapter looks at the infrastructure of blue (water resources) in Bahrain's built environment, as well as the efficacy of blue in keeping the country green. Beginning with a description of the Bahraini light and the colors of the sea, from technical, historical, and social perspectives, the chapter studies the water system and the politics of treated sewage effluent (TSE). Over half the water of the state is used in the irrigation of green space in Bahrain—an indication of the enormous value accorded to green. Because Bahrain is an island, the intensity of the light and the colors it animates are amplified due to the humidity generated by the surrounding sea.

In the great nineteenth-century British world cycle of gold rushes, individualist wealth seeking became associated with democratic politics, and views about the public rather than private benefits of gold became increasingly the preserve of conservatives. In Georgia, governor George Gilmer declared in 1830 that the gold diggers were “appropriating riches to themselves, which of right equally belong to every other citizen of the state,” but he soon suffered electoral defeat. In 1850s California and Australia, individual miners were rapidly associated with a democratic and egalitarian future, even with the public good. This helps explain the oddly uncontested decisions to allow mining on public—and, in many places, private—land and use of public resources such as timber and water. This chapter is by David Goodman.

The aim of this chapter is to explain the challenges of decentralisation and management of water as economic good principles of integrated water resources management (IWRM) in Malawi in the rural areas of Ntcheu, Balaka, and Mangochi. Semi-structured interviews, focus group discussions, community meetings, and observation of water points were conducted. It was established that households and other state institutions prefer to receive services from Mpira-Balaka Water Users Association, which subsidizes households, rather than Southern Regional Water Board, which operates along commercial lines. The chapter questions the focus in the implementation of IWRM, which remain the establishment and fixing of decentralised institutions whilst recognising water as an economic good.

Abstract From its origins in the 1850s, California’s economy has been fueled by entrepreneurs who took advantage of the opportunities that arose and had a belief that they could engineer solutions to the problem at hand. California’s capacity for innovation has been the key aspect of every stage of its industrial evolution. It began with efforts to extract resources and control water and it has led to aerospace and microelectronics. Actions taken by public as well as private institutions in California clearly have made a difference in the economic development of the state. Investments in education, water, and transportation infrastructure had a clear payoff in terms of state economic growth. California’s entrepreneurial climate exists in part because of public policy decisions.

The fight over the Humboldt Bay Wastewater Authority (HBWA) project had turned bitter and personal. HBWA’s attorney, John Stokes, and most of its board members had lobbied hard against Arcata’s alternative treatment plan. Dan Hauser, usually diplomatic, seethed with resentment. “HBWA has set itself up as the enemy,” he wrote in a September 1977 opinion piece in the Arcata Union. “Therefore, we have no alternative but to defend ourselves by attacking HBWA . . . We must stop this $52 million boondoggle.” Hauser, still Arcata’s representative on the HBWA board, pledged to work toward the “total redesign or total destruction” of the regional sewage system. Other members of HBWA were growing panicky. The Committee for a Sewer Referendum’s lawsuit kept the board from issuing bonds to finance construction, while inflation caused the project’s already huge price tag to balloon. Concealing the move from Hauser, the board applied for a $5.9 million loan from the US Environmental Protection Agency (EPA). Arcata, at Mayor Hauser’s suggestion, promptly sued HBWA for seeking the loan without the city’s consent. Meanwhile, Hauser organized an appeal for Arcata’s wetland treatment system before the State Water Resources Control Board. The city mustered support from representatives of the US Fish and Wildlife Service and Audubon Society, along with academic experts on Humboldt Bay oysters and low-tech sewage treatment. Wade Rose, the shaggy upstart from the governor’s Office of Appropriate Technology, would speak. After Stokes cross-examined Rose at the regional board hearing, “it became a crusade for the entire Office of Appropriate Technology,” Hauser explains. “They singled out HBWA as the ultimate in obsolete technology and concrete overkill.” When the Arcata contingent arrived at the state board hearing in Sacramento, one of the board members, brandishing a newspaper clipping in his hand, called Hauser forward. The clipping was a story from the Arcata Union, quoting Hauser saying that the marsh project would not get a fair hearing. “He asked why I was there if I believed they were already biased against me,” Hauser remembers. “I told him we have to go through this process to get to the next step.”

ABSTRACT Mount Diablo State Park exemplifies many other conservation areas where managers balance the dual missions of protecting natural resources while providing public access. Roads and trails that crisscross the park are etched into the geomorphic surface, capturing and redirecting storm runoff, and presenting both a challenge for soil conservation and a consequence of construction and maintenance. We used field mapping, remote sensing, and modeling to assess erosion along the roads and trails in Mount Diablo State Park, which encompasses the headwaters of several urbanized watersheds. The field mapping in 2011 determined that 56% of the assessed roads and trails required either repair or reconstruction to control erosion and that ~67% of the culverts in the park required either repair or replacement. Aerial photography and modeling showed that other erosion (unrelated to roads or trails) preferentially occurred during wet periods, in specific lithologies, and on convergent slopes. Although lithology and climate drive slope-forming geomorphic processes, we found that the road and trail system (1) expanded the stream network with a capillary-like system of rills, (2) catalyzed prolonged erosion, and (3) altered the timing and pattern of sediment yield. In addition to water-driven erosion during wet periods, road and trail surfaces were subject to mechanical and wind erosion during dry periods. Spatially, dry erosion and runoff both conformed with and crossed topographic gradients by following the road and trail network. Road- and trail-induced erosion occurred across a wider range of rock properties and slope geometries than is typical for other erosion. Hence, the roads and trails have expanded the spatial and temporal boundary conditions over which geomorphic processes operate and, due to continual soil disturbance, have accelerated erosion rates. Although road density is a commonly used metric to rank road-related impacts at watershed scales, it misses both spatial variability and the opportunity to identify specific road and trail segments for remediation. We developed a spatially explicit scoring scheme based on actual erosion and the potential for sedimentation of discrete waterbodies. The data were incorporated into the park’s road and trail management plan in 2016.

In 1905, the state board of health for Connecticut looked back over the last half century and noted the tremendous change that had occurred. In the first half of the nineteenth century, “all the towns and cities in Connecticut were very rural in character, and nowhere were populations so dense from overcrowding as to affect the public health. Hence there was no conspicuous disparity in the salubrity of different towns.” As Connecticut industrialized and urbanized, disparity in the salubrity of different parts of the state increased. It became “an accepted fact, sustained by careful observation, that the death-rate was always higher in cities than in the country.” Although the pure past to which the Connecticut State Board of Health alluded may not have been as pure and healthful as it assumed, nonetheless, the board was correct in noting the increase in mortality in the industrial towns and cities that grew up over the century. Growing awareness of the “effect of environment and employment upon the prevalence o f . . . disease” created momentum for public action. The vision of an activist state promoting public health and protecting the citizens, particularly the “weak” and “poor,” from the vagaries of the market—whether those were represented by “foul” water or depleted resources—increasingly found support among other reformers. The urban industrial setting that made Connecticut’s cities so unhealthy also generated concerns overworking children, long working hours for women in the paid labor force, industrial diseases, and overcrowded tenements. Like the antipollution reformers, those who were concerned over these conditions increasingly looked to the state to legislate remedies. Laws that limited women’s working hours and child labor and that controlled the conditions of tenements found favorable hearings among legislatures attuned to an electorate demanding reform of the conditions they found in their daily lives. Environmental reformers—both public health activists and supporters of protection for fish—were important voices in this rising chorus that favored a more active state. The momentum for public action began in Massachusetts, the most industrialized and urbanized New England state, and spread to the other states of the region and ultimately to the entire nation.

The open political conflict that characterized the early relationship between the states of the Colorado River basin has given way to extensive cooperation, even as water scarcity poses an ever–greater challenge for management of the basin’s water resources. Yet halfway around the world, in India, history threatens to repeat itself. In April 2013, the Indian press reported a most unusual case of espionage: the police in Kerala, a southern state engaged in a long–running river basin dispute with the adjacent state of Tamil Nadu, announced that they had uncovered a spy working on behalf of their neighbor, who they charged had “developed a wide network with officials and ministers to source vital info regarding Kerala’s stand on interstate water issues” (Express News Service 2013). Both the 1934 invocation of martial law and the more recent 2013 allegation of espionage are poignant examples of behavior common to countries but not to subnational states. Though fortunately rare, they attest to the gravity of conflict over water that occurs within countries, rather than between them. These subnational hydropolitics are both surprisingly common and conceptually puzzling, for they occur despite the existence of relationships and institutions, ranging from water ministries to political party structures, that may be expected to prevent them. This book helps to explain why water so often proves to be a focal point for political conflict within nations as well as among them. This conclusion first reprises the argument of the book and its implications, then discusses directions for future research. Finally, it offers some policy recommendations for countries like India where sustainable water resource management is undermined by extensive subnational political conflict over water. In a world where water needs are growing rapidly even as water supply variability increases due to climate change, it is critical to understand the politics of water at subnational as well as international levels—and how this understanding can be leveraged to improve water resource management.

Lured by the potential for substantial wealth, Americans have focused a disproportionate share of their industrial effort on extracting and processing resources that are both scarce and in high demand. Gold and silver were always valuable and eagerly sought, but in the nineteenth century, the demand tor other nonferrous metals and (or petroleum rose to unprecedented levels. Obtaining these scarce, nonrenewable resources brought new patterns of industrial land use and new environmental consequences. The continuing effects on our land, water, and air are serious concerns in American society today. The hope of finding gold and silver, the metals of wealth and display, drew numerous adventurers to North America in the seventeenth century. In the East, those hoping to repeat the Spanish experience in South America and Mexico were disappointed. Although colonial prospectors did discover small deposits of nonferrous-metal ores on the east coast and in the Appalachians, most of the metals were not in the precious category. There was a demand for utilitarian metals as well: English colonists depended on lead for pipes, window carries, and shot; they cooked with copper kettles, drank the products of copper stills, and set their tables with pewter (a tin alloy) tableware. Nevertheless, Americans generally found it cheaper and easier to use imported nonferrous metals until the mineral resources of the center of the continent were exploited in the nineteenth century. Iron was the only metal extensively mined in the English colonies. One of the few relicts of pre-Revolutionary nonferrous metallurgy is the Simsbury Copper Mine in East Granby, Connecticut. This mining enterprise obtained its charter in 1706. The state now preserves the site, not as an industrial monument but because the mine served for a time as the state prison. Visitors can enter the underground workings. Physical evidence of the first gold discovery in the United States, in 1799, exists at the Reed Gold Mine, a state historic site near Georgiaville, North Carolina. Most of the milling survivals are from later development at the mining site in 1854 and 1896. North Carolina led the nation in gold production until the California gold rush of 1849.

Land-based water injection into the combustor of gas turbines is a state-of-the-art technology, which is a low-risk, low-cost option for reduction of gas-turbine emissions. A controller for a water-injected combustor (WIC) system was designed for automatic control of water injection. Steady-state tests of the WIC system in an LM2500 propulsion-engine facility yielded basic engine-interactive data for the WIC’s unique automatic software logic. The steady-state tests demonstrated anticipated NOx reductions in conformity with proposed (but not implemented) California Air Resources Board (CARB) mandates. The controller automatically compensates for the effects of humidity, temperature and engine load. This automatic response was expressly designed to deliver acceptable water rates even during the abrupt power excursions encountered in emergencies, including collision-avoidance crashback maneuvers. The transient test data indicated unacceptable flameout in the engine during engine deceleration to idle speed. Detailed analyses of the flameouts show that the controller can reduce water flow within two deciseconds of a change in power demand. However, the residence time of water in the manifolds can be about a second for some operating conditions. Several fixes for this problem are described.

Southern California and Baja California share, besides a dynamic social and economic exchange and 226 kilometers of borderline, an important natural resource: water from the Colorado River. Both areas have arid and semiarid climate in large zones and local fresh water sources are scarce, so water imports from the Colorado are strategic for their continued social and economic growth. Southern California’s water supply comes from the State Water Project, the Colorado River Aqueduct and local sources; in turn, Baja California depends mostly on the water supplied by the Colorado River, with an aqueduct that serves the Pacific coastline cities of the state. Both water supply systems are considered high energy consumers, affecting the quality of life in the region. The sustainable development of both communities is a challenge to Mexican and American public policy planners who must recognize that, to meet the future water demands to support sustainable development in this area it will require improved utilization and management of water resources. In this paper, water supply sustainable indicators were calculated for southern California and Baja California to evaluate and compare their performance towards sustainability. Findings show big differences in the indicators like water use per person, percentage of the cost of water relative to household income, cost of electricity to convey water, etc. High contrast in both economies makes up for these differences, but as water stakeholders of an only source, that is, the Colorado River, Mexico and the United States should avoid those imbalances in water use and management efficiencies, as it might affect its availability and cost, bringing potential conflicts and disturbing the traditional friendly coexistence and growth of both communities.

Metropolitan Water District (Metropolitan) is a public agency charged with providing its service area with adequate and sufficient supplies of high quality water. Metropolitan was incorporated in 1928 by an Act of the California Legislature to serve its 13 original founding Member Agencies. Today, Metropolitan provides water to 26 cities and water agencies serving more than 19 million people in six counties in Southern California. On average Metropolitan delivers 1.7 billion gallons of water per day. California, the third-largest state in the U.S. by land area, has a diverse geography including foggy coastal areas, alpine mountain ranges, hot and arid deserts, and a fertile central valley. California is also the most populous state, exceeding 37 million people in 2010. California’s large population drives the interlinked demands for water and energy in the state. The water-energy nexus in California is highlighted by the fact that two-thirds of the population resides in Southern California while two-thirds of the state’s precipitation occurs in Northern California. Separating Southern California from the rest of the state is a series of east-west trending mountain ranges. Water conveyance projects have been constructed to address this north-south water imbalance and to also import supplies from the Colorado River, hundreds of miles east of Southern California population centers. The movement of water on this scale requires significant energy resources. The California Energy Commission (CEC) estimates that water-related energy use consumes 19% of the state’s electricity and 30% of its natural gas usage every year, and demand is growing. Energy management is a critical concern to Metropolitan and other California water agencies. These issues drive water and energy leaders to jointly manage energy and water use to ensure long-term mutual benefits.

Overwhelming scientific data confirms that the primary cause of global warming is anthropogenic greenhouse gas (GHG) emissions (IPCC, 2014). The resulting extreme weather events (sea level rise and extended wildfire season amongst others) contrast with the discrediting of climate science at the national level beginning as early as the late 1980s (McCright & Dunlap, 2011). This discrediting has led to a lack of national sustainability policy and has compelled the State of California to take a leadership role in addressing the issue. California’s legislative policies and Gubernatorial executive orders include the reduction of GHG and electricity consumption by targeted dates (California Air Resources Board, 2006, California Office of the Governor, 2020). State Agencies, including California’s Community College system, have financial incentives to meet these goals.

Energy and hydraulic efficiency are important goals for the sustainable development of water supply systems. The objective of these systems is to guarantee the delivery of enough water with good quality to populations. Although in order to achieve that, energy for pumping is needed, representing the main cost for the companies to operate the systems, since the energy costs vary with the amount of pumped water and the daily energy tariff. Water and energy are critical resources that affect virtually all aspects of daily life. Ensuring these resources are available in sufficient quantities when and where society needs them entails significant investments in planning, infrastructure development, operations and maintenance bills. Ever-increasing utility costs reduce profits, erode capital and maintenance budgets, increase product costs, and reduce competitiveness. Pumping systems are critically important to the operations of a water treatment plant. The amount of energy consumed by many long-running pumping systems often results in a substantial addition to a plant’s annual operation costs. Therefore, these systems are a natural target to reduce energy consumption. Producers and users of pumps must design highly efficient pumping systems. The efficiency of these systems must be evaluated involving the multiple factors that often are difficult to understand for many users, consequently they overlook the energy costs and energy reduction potential on these systems. Methodologies that can maximize energy cost savings while satisfying system performance criteria should be sought for the design and management of the water distribution systems. This paper compares operating characteristic curves (OC curves) from a pump manufacturer with the curves obtained with field data, and evaluates the efficiency of the pumping system of raw water of a water treatment plant in Mexicali, Baja California, México, which consists on a group of parallel identical pumps. The assessment also analyses the potential savings in costs and emissions of GHG related to the energy consumption of the pumping system if the operation conditions were the optimal, with the objective of minimize negative effects to the sustainable development of the region. Measurements of hydraulic and electrical parameters of the pumping system were made and efficiencies calculated. Actual characteristic operation curves were plotted and compared to those from the pump’s manufacturer and up to 31% (average) difference in the efficiencies was found. Also emission factors of the electrical generation system of the state were applied to obtain the amounts of actual GHG emissions due to the operation of the pumps. The software PSAT was used to compute potential annual savings in MWh and costs and the results employed to calculate possible reduction in emissions.

<div class="htmlview paragraph">In regard to small utility engines used in lawn and garden equipment and other commercial or industrial equipment, exhaust emission regulations have been implemented since 1995 in USA. In the State of California, USA, California Air Resources Board (CARB) Tier 2 emission regulations became effective from 2000. At this stage, the handheld engines are almost two-stroke engines, but this Tier 2 emission regulations are very stringent for HC emissions. In addition, the handheld engines are small, and so they do not have enough muffler volume to be equipped with larger catalysts. This paper describes the newly developed catalyst for two-stroke small engines, which is compact and excellent in HC conversion, to meet above requirements.</div>

This paper presents the results of a demonstration of a unique water distillation system at the Musco Family Olive Plant in Tracy, California. The Musco REWS (Renewable Energy/Water System) was developed by Combined Solar Technologies (CST) of Carmel Valley, California using its SteamBoy™ brine boiler technology. The system is powered using solar thermal and biomass energy. The notoriously hard to clean waste water from the olive canning process was a challenge for CST, a start-up company who had previously done successful technology demonstration projects for the California Department of Water Resources (agricultural drainage water) and Clint Eastwood’s Tehama Golf course Water Treatment Plant (Reverse Osmosis Brine). The olive waste water at the Musco plant contained a high concentration of salts as well as organic materials. CST successfully treated water directly from the plants waste water stream (12,000 TDS) as well as the water from the plants Title 27 ponds (67,000 TDS). The CST processed water averaged 250 TDS. The CST REWS at the Musco olive facility uses one of the plants waste (olive pits) streams to provide the heat energy for the process. The olive pits are combusted in fluid bed burners that are specially designed for olive pit combustion. The Musco plants 200 tons per week of olive pits contain 8800 btu/lb (dry). The olive pits are fed into the CST burners where the heat energy is used to heat a heat transfer fluid (HTF) to 450F. The HTF is then directed to the SteamBoy™ brine boilers. The heat from the HTF evaporates the plants waste water under pressure. The resulting pressurized saturated steam is then used to power SteamBoy™ steam engine/generator sets. The engines are set up to leave large quantities of heat in the exhaust. That heat is used to take the remaining solids and sludge to a dry state in custom built drying pans that separate the minerals from the water, leaving a very high concentration of organics in the remaining water. That water is used in the burners for temperature control and as a way to eliminate the organics with combustion. The exhaust from the combustion of the olive pits goes first though an electrostatic particle separator and then to a selective catalytic reduction system. From there the exhaust is directed to bubbling algae tanks that reduce the CO2 by over 50%. The system has completed a successful demonstration phase and is now being upgraded to a full scale plant (50,000 GPD).

This paper describes a unique analytical model created to assess the maximum potential for algae production in Texas. The model, which merges engineering, biology and geosciences into a singular analysis, aims to identify suitable growth locations and estimate the quantity of algae-based oils that can be potentially produced in Texas. The model incorporates geographically- and temporally-resolved data on sunlight, anthropogenic CO2 emissions, and saline or brackish water availability. These data are then overlaid with first-order biological approximations for algae growth calculations in order to create maps of algae growth potential. Solar insolation data were obtained from measurement locations throughout the state for varying time scales spanning many years from the Texas Solar Radiation Database (TSRDB). CO2 emissions were compiled from area and point sources (such as natural gas and coal-fired power plants) from the Energy Information Administration and Environmental Protection Agency. Water data for wastewater treatment plants and saline aquifers were obtained from the Texas Commission on Environmental Quality and the Texas Water Development Board. A home-built MATLAB code uses these data, along with engineering approximations and the ability to manipulate different assumptions to calculate algae growth by location and time period. For each location, the model calculates potential oil yield, biomass produced, growth rates, water and CO2 consumed and land used. Standard pond and tubular photobioreactor dimensions have been used to model real world production facilities. Realistic limits for growth rates, photosynthetic efficiencies, photosynthetic flux tolerances and oil content are also incorporated. These parameters can be varied to approximate different algae strains and growth conditions. The model assumes reactors to have ideal mixing, optimal pH and temperature controls in place. This preliminary resource assessment estimates that Texas receives an average of 375 W/m2 annually, produces 409 million tons per year of CO2 from the industrial and electrical power sectors and has approximately 1.4 trillion gallons per year of available water on a sustainable basis. The computational model estimates that between 44 and 167 million tons of algal biomass and 3.1 to 12 billion gallons of lipids can be produced annually in Texas based on the combination and availability of these resources.
