Abstract (sommario):
Although many cities have planed to develop sewerages in developing countries, sewerage establishment still requires huge investment and engineering efforts. Improvement of existing sanitation facilities may contribute the betterment of urban sanitation before sewerage establishment. The purpose of this study is to propose a measure to improve urban sanitation in areas where a sewerage development plan is proposed but has not been yet established, based on a case study in Hanoi, Vietnam. We found that 90.5% of human excreta flowed into septic tanks. However, 89.6% of septic tanks have never been desludged in the past and their performance was observed to be at a low level. The study also showed that if they introduce regular desludging with a frequency of once a year, they can eliminate 72.8% of COD loads from septic tanks. It was indicated that the performance can be dramatically recovered by regular desludging, which could contribute urban sanitation improvement in Hanoi. In conclusion, the performance recovery of septic tanks by regular desludging was proposed as a provisional-and-urgent measure for urban sanitation improvement, together with the septage treatment in sewage sludge treatment facilities, which should be established earlier than other facilities of sewage treatment systems.

Abstract (sommario):
Simplified sewerage is considered the only periurban sanitation technology that has a chance of ensuring that the WHO/UNICEF target of Sanitation for All by the end of 2025 is achieved. On-site sanitation technologies, such as ventilated improved pit (VIP) latrines, pour-flush toilets and ecological sanitation toilets, are either technically infeasible in high-density areas or more expensive than simplified sewerage. Simplified sewerage is often institutionally and professionally acceptable to sewerage authorities simply because it is a sewerage system, albeit different from conventional sewerage in that it uses small-diameter sewers laid at shallow gradients (e.g., 100-mm sewers at 1 in ∼200). The success of simplified sewerage in Latin America, principally Brazil, has to be replicated on a truly huge scale in Africa and Asia where most of those without adequate sanitation live. In areas where even simplified sewerage is unaffordable, the only option is to install communal sanitation blocks of the type implemented in India by Sulabh International.

Abstract (sommario):
There has been conducted a study of interdependence between technical and economic researches of diameters calculation of water pressure supply and sewerage networks. There has been offered the method to calculate the optimal diameter of water pressure supply and sewerage networks made of polymeric pipes. This qualitative and quantity methodology includes, firstly, the observation review of Ukrainian water supply and sewerage networks and, secondly, the survey of financial and economic documents of water supply and sewerage economy. The factual basis of the study is the initial data of statistical monitoring of work conditions of water pressure supply and sewerage networks. The paper proposes using the net present value (NPV) to calculate the optimal diameter of water pressure pipes made of polymeric materials, which, finally, decreases capital and exploiting expenditures and considers the maximum income for water supply and sewerage economy (WSE).

Abstract (sommario):
Households with access to wastewater sewerage in Pamotan in 2022 only be 69.9%. This study aims to find out the factors related to household wastewater sewerage ownership in the Pamotan Community Health Center Working Area. This research was an observational analytic using a cross-sectional design. The research population was all families in Pamotan subdistrict villages with the lowest ownership of wastewater sewerage, with a sample size of 90 families. The independent variables are land availability, length of year residence, knowledge, education, and income for the dependent variable, that are ownership of the Waste Water Sewerage. The data were analyzed using univariate and bivariate statistics, employing the Chi-Square test. The results of the study showed that land availability (p=0.04), education level (p=0.018), knowledge level (p=0.003), and income (p=0.00) are related to household wastewater disposal ownership while the length of year residence (p=0.257) is not related to ownership of household wastewater sewerage in the Pamotan Subdistrict. Based on the research results, the length of year residence is not related to household wastewater sewerage ownership because people's old habits that are not good at managing household wastewater result in wastewater sewerage ownership behavior not fulfilling standards.

Abstract (sommario):
In recent decades South Africa has witnessed a substantial growth in its urban population. This growth has been accompanied by the mushrooming of informal settlements (shantytowns) flanking more formal development. The lack of adequate urban drainage in many of these informal settlements has resulted in extremely polluted environments which add to the disease burden of the poor people who live there. In many instances, informal settlements in South Africa are established on marginal land that is inherently difficult to service using conventional gravity sewerage. International experience has shown that various alternative wastewater collection systems may present more appropriate ways of providing water-borne sewerage in areas that are difficult to service by conventional means. Alternative sewerage schemes have however had a poor record of success in South African informal settlements – primarily stemming from the implementing agencies' failure to adequately address various social and institutional factors. In this paper, a review of South African experiences with simplified sewerage, settled sewerage and vacuum sewerage in urban informal settlements is used to highlight the key constraints that currently impede the application of these technologies.

Abstract (sommario):
Abstract We argue that, if the sanitation target of the Sustainable Development Goals (universal access to ‘safely-managed’ sanitation by 2030) is to have any chance of success, then a community-sensitive top-down planning approach has to be adopted for sanitation provision in high-density low-income urban areas in developing countries, as ‘bottom-up’ planning is much more time-consuming and not yet successfully proven at scale. In high-density low-income urban areas, there is only a limited choice for safely-managed sanitation: (i) simplified/condominial sewerage (which becomes cheaper than on-site sanitation systems at the relatively low population densities of 160–200 people per ha), (ii) low-cost combined sewerage (if it is cheaper than separate simplified sewerage and stormwater drainage), (iii) community-managed sanitation blocks, and (iv) container-based sanitation (the last two of which are suitable, especially in slums, when neither simplified sewerage nor low-cost combined sewerage is affordable or technically feasible). These four sustainable sanitation options are as scalable in developing countries as conventional sewerage has been in industrialized countries.

Abstract (sommario):
Urban sanitation issues should be tackled strategically, and may be addressed effectively when sewerage development is pursued in conjunction with complementary sanitation measures. Five sanitation improvement scenarios employing sewerage, night-soil collection-and-treatment (NSCT) system, and/or septic-tank improvement by annual desludging were analyzed from the perspective of COD loads, total nitrogen loads, and cost under the conditions found in Hanoi, Vietnam. Compared to the development of sewerage alone, the scenario of developing NSCT systems in a complementary manner with sewerage development was estimated to be the most effective for a rapid decrease of both COD and total nitrogen loads. However, it may be difficult in some cases to replace ordinary water-flush toilets by the micro-flush toilets that are used in NSCT systems. In this case, the scenario employing septic-tank improvement in conjunction with sewerage development may be effective for a rapid decrease of COD in locations where septic tanks are widely used under poor maintenance conditions and nitrogen pollution is not serious compared to COD. It was calculated that the two scenarios above would respectively require cost increases of 16 and 22% over the sewerage development scenario.

Abstract (sommario):
When a malfunction in the collection system occurs and a pipe overflows, the wastewater may be discharged in the natural environment. To avoid such pollution, nuisances to inhabitants living nearby and extra cost for the operator, there is an issue of detecting early enough the buildup of obstructions in sewerage pipes in order to react before the damage is done. The aim of this thesis was thus to develop a decision support tool to detect obstructions and to optimize cleaning operations. Some additional specifications were the file size for sending by email, the simplicity of setup and use, the visual attractiveness and a quick visualization of results. The tool consists of two Excel files coupled with a database which permits to send a daily email to the operator with the functioning state of each measurement point. However, the tool does not do everything, human analysis is necessary to have a critical eye on the results and to decide when to trigger a cleaning operation. The main perspective at the end of this thesis is the replacement of the preventive cleaning operations that were previously performed with a fixed frequency per year by conditional cleaning operations triggered by the tool and to observe the decrease of cleaning operations. Other perspectives are to spread the tool to other sites and to use the received feedbacks to adjust the different parameters and eventually to determine an automatic trigger condition of cleaning operations.

Abstract (sommario):
As a modern metropolis, Shanghai has a registered population of 18.8 million in 2011, and the permanent population has been more than 20 million. As a result, Shanghai produces more than 6.3 million cubic meters of sewage per day which is considered as a massive test for Shanghai’s sewerage treatment system. Given the high proportion of time spent on the literature review, this study has investigated how the whole system works in Shanghai. To do this, Shanghai sewerage systems were divided into two parts – the drainage system and the sewage treatment system, and they were introduced respectively following the track of history development process. It was done by combining previously published theses, study reports, governmental documents, overt information by companies and news reports. It showed that, in 2009, Shanghai’s government established a basic formation of six centralized sewage treatment systems in co-existence with 52 sewage treatment plants. In the same year, the sewage treatment rate reached 78.9%, which can be considered a leap compared with the 62.8% figure in 2003. In spite of that, the gap between sewage treatment in Shanghai and that in developed countries still exists. By comparing Shanghai Bai Longgang sewage treatment plant with Halmstad Västra Stranden's waste water treatment plant, it can be concluded that the gap was embodied in differences of inflow condition, relative low discharge standards and poor treatment capability.

Resumo: O tratamento de esgoto sanitário em lagoa de decantação anaeróbia e disposição controlada de água residuária no solo é uma alternativa de baixo custo para o reuso de águas residuárias na agricultura. Nele, o esgoto sanitário é depositado em uma lagoa de decantação anaeróbia com retenção hidráulica de sete dias, após o que a água residuária é conduzida para rampa de solo franco argilo-arenoso, com cobertura vegetal de gramínia Cynodon sp, para disposição por escoamento superficial, seguindo-se sua infiltração e percolação. O objetivo desse trabalho foi verificar a eficiência desse sistema na eliminação e/ou inativação de adenovírus humanos (HAdV) e rotavírus (RV). Amostras de 1L de água residuária foram obtidas em quatro coletas, em intervalos de sete dias, na entrada do esgoto bruto (EB), no ponto de aplicação na rampa (0m) e nos pontos da sua superfície após 10, 20, 30, 35m e 40m. Sob a rampa, a 1m de profundidade e distantes 30m (30-1) e 35m (35 -1), dois pontos foram amostrados. Antes do ponto 0m, pontos de testemunha a 1m de profundidade e distantes 2m (T1) e 0,5m (T2) da rampa, e um ponto do lençol freático (LF) a 3m de profundidade, também foram coletados.As água residuárias foram concentradas de 1.000 a 5.000 vezes por filtração e eluição em membrana eletropositiva e ultracentrifugação. Nos eluatos obtidos, após extração de DNA, a presença de HAdV foi pesquisada por PCR e nested-PCR. Para a detecção de RV usou-se RT-PCR e duplo-semi- nested-PCR. Eluatos HAdV positivos foram inoculados em células HEp-2 e após até cinco passagens a presença de HAdV foi confirmada por PCR.. HAdV foram detectados em 29 das 35 amostras analisadas, sendo positivos todos os pontos de EB e da superfície da rampa. Em profundidade, sob a rampa, quatro amostras foram positivas, além de outras duas em T2 e uma em LF, o que demonstra a percolação desses vírus no solo com contaminação do LF. Quando testadas em células HEp-2, nas amostras do EB e dos pontos 0, 30, 35 e 40m a presença de vírions foi determinada, enquanto nos pontos 30-1m e LF os HAdV não foram infectivos. Esses resultados permitem concluir que o sistema não foi eficiente para remover e/ou inativar HAdV. Por outro lado, pode-se afirmar que os HAdV são indicadores virais adequados para esse sistema, desde que mantida a metodologia aqui empregada. Uma amostra de EB foi positiva para RV (genotipos G1 e G2), resultado esse que não permite qualquer conclusão. Para o reuso da água residuária advinda desse sistema impõe-se a associação de processos de desinfecção para a eliminação de HAdV
Abstract: Urban sewage treatment by an anaerobic process with overland flow system is a cheap alternative to reuse domestic effluents in agriculture. In this procedure, wastewater remains in an anaerobic pond for seven days, and then it is spilled from the top of a 40-meter extension slope covered with Tifton 85 (Cynodon sp) grass in order to surface flow and percolate until it reaches groundwater. The objective of this work is to determine if this procedure could be effective in removing and/or inactivating human adenoviruses (HAdV) and rotaviruses (RV) in a test unit in Limeira - SP, Brazil. Samples were collected every seven days from different spots in four sampling events totalizing one liter of wastewater. Sampling points were chosen at the raw sewage (EB), on the surface of the slope at 0, 10, 20, 30, 35 and 40 meters, and down one meter from the surface of the slope at the 30- and 35-meter points (30-1 and 35-1). Other points upslope were used at a distance of 2 meters (T1) and 0.5 meters (T2), beyond a 3-meter depth and 1-meter distant spot (LF). All samples were concentrated from a 1000 to 5000 times by filtration through electropositive microporous membrane followed by ultracentrifugation. HAdV detection was performed by both PCR and nested PCR. RV detection was accomplished by both RT-PCR and duplex semi-nested PCR. The positive samples for HAdV were inoculated in HEp-2 cells, and confirmation of the virions was performed by PCR. HAdV were detected in 29 of the 35 samples tested including in all samples both from the EB and from the surface of the slope. HAdV tested positive in the two T2, in one LF, and in the four samples underneath the slope. In HEp-2 cells HAdV virions were detected at the EB and at 0, 30, 35, and 40 meters on the surface of the slope. Spots 30-1 and LF were tested in HEp-2 cells, resulting negative to the presence of infective viral particles, although they tested HAdV positive. These results attest to the inefficiency of the proposed system of sewage treatment in removing and/or inactivating HAdV; however, maintaining the methodology used in this research, HAdV proves to be the appropriate viral indicator in this system. In relation to RV, no conclusions can be extracted since just one sample from the EB was RV-positive (G1 and G2 mixture). Finally, before reuse in agriculture, the effluents from the anaerobic pond should be disinfected to eliminate these viruses

Abstract (sommario):
This research examines the use of microcomputer-based expert systems as a diagnostic tool and an operational aid of conventional secondary wastewater treatment facilities. The research has shown that rule-based systems are well suited for the domain of wastewater treatment facilities operations using observational information. Advances in expert systems software combined with increased microcomputer processing power have made this development work possible with personal computers. These systems possess the capability to provide fully automated diagnostics and process control as well as acting as a teaching and development tool for operators in full-scale treatment facilities. The thesis describes the technical aspects of wastewater treatment as applied to the development of a finished knowledge base system called WASTES (WAStewater Treatment Expert System). The thesis also discusses the development of the knowledge bases from their sources to implementation in the system. Recommendations and conclusions are also presented along with potential areas for further research.

Abstract (sommario):
The proposed methodology to most effectively manage intermittent combined sewage discharges into urban watercourses in the UK is given in the Urban Pollution Management (UPM) manual. The method is based on the use of detailed computer models of the sewerage system, wastewater treatment plant and receiving watercourse. Solving intermittent discharge problems using UPM, often requires the installation of in-sewer storage tanks. However, recent research from Germany and elsewhere (e.g. Austria and Denmark) has shown that this type of solution may be of little benefit with respect to the total emissions discharged from the entire system, where emissions from both the Combined Sewer Overflows (CSOs) and the Wastewater Treatment Plant (WTP) are considered together. This is because, in certain situations, WTP efficiency can be compromised by the prolonged periods of dilute (low nutrients and substrate) inflows which can result from the draining down of in-sewer storage tanks. The earlier research in Germany and elsewhere has been concerned with long term total emissions (annual loads) and not the problems specific to individual sites, or the benefits and/or limitations of storage with respect to acute pollution. Thus the principal objective of the research described here has been to substantiate and quantify the total emission problem by means of detailed modelling, via an evaluation of the likely storage volumes which could give rise to total emissions problems for the Perth wastewater system. Following this, a general method has been developed to investigate and resolve total emission problems related to acute pollution effects. As WTP disruption due to flow dilution can last for a prolonged period after even a single rainfall event, computational simulation times need to be long enough to represent the delay in WTP performance returning to normal operating conditions. As long term continuous simulation is usually impractical due to protracted computational times, a method referred to as the Total Emission Analysis Period (TEAP) has been developed. This will define the minimum required computational time and rainfall inputs to be used to ensure that the effect of in-sewer storage on total emissions could be modelled. Utilising the TEAP method to analyse total emissions it has been concluded that increasing volumes of storage would not be expected to create a total emission XXVI problem with respect to the Biochemical Oxygen Demand (BOD). Consequently, it was concluded that the best storage volume with respect to BOD was the minimum volume which would allow compliance with receiving water quality standards. No direct comparison could be made with the conclusion derived from the German research due to the long term nature of their analysis, however, it would appear from an interpretation of their results, that similar findings were obtained. With respect to ammonia, it was found that increases in total emissions can occur as, ammonia concentrations, unlike BOD, do not increase at the start of a storm due to first foul flush effects. Consequently, any increased emissions from the WTP would not be offset via a reduced CSO spill load. It was also found, however, that increasing volumes of storage would not be expected to exacerbate acute pollution problems within a receiving watercourse and that both large and small storage volumes had the potential to give rise to very similar degrees of WTP disruption. This was due to the way in which different hydraulic loading conditions (caused by the different volumes of storage) affected the bacterial concentrations in the reactor. The conclusion that storage would not provide a significant benefit for ammonia total emissions was supported by the Austrian and Danish research.

Abstract (sommario):
Today’s rapid growth in population on sub-urban areas has caused an increase in fecal coliforms to be discharged to down-streams and lakes. The unaffordability of conventional sewerage systems makes it inaccessible to big part of the population of rural communities to receive proper sanitation. Since population growth is only projected to increase during the next few years, action is necessary to change the course of the future of rural communities, more specifically described on this report, Louisiana’s communities. One option to offer affordable sewerage systems to the Louisiana region is that we utilize of the Simplified Sewerage technology. Simplified Sewerage has been tested on several municipalities around the globe, especially in Brazil. The results of its application have proven to be conclusive and beneficial to communities.

Jourdain, Jean-Loup. Evaluation Tool to Implement Good Practices in the Area of Customer Management for Water and Sewerage Operators. Inter-American Development Bank, gennaio 2011. http://dx.doi.org/10.18235/0008832.

Testo completo
Abstract (sommario):
The following is a tool developed by the Water and Sanitation Division of the IDB for evaluating customer management practices in use by water and sewerage utilities. In order to facilitate the use of this tool, all matters which relate to customer management have been grouped into four main functional areas: the "Billing Factory" (or the recurrent billing and collection activities); Revenue Management; Customer Care (management of contacts with customers); and Customer Marketing, a relatively new activity in water and sewerage companies, which aims to study and propose solutions tailored for various types of customers. The tool is an Excel program, designed to be freestanding. This tool may be used in two major ways, as a support for dialogue between a professional of customer management and an external expert, or directly by the company itself to measure the consistency of different approaches to customer management and perceptions regarding their effectiveness.

Briceño, Bertha, e Virgilio Galdo. Evaluating the Impact on Child Mortality of a Water Supply and Sewerage Expansion in Quito: Is Water Enough? Inter-American Development Bank, maggio 2005. http://dx.doi.org/10.18235/0011133.

Testo completo
Abstract (sommario):
This paper explores the impact that a water supply and sewerage (W&S) expansion had on child mortality in Quito, Ecuador. Studies have typically estimated the effects of this type of interventions comparing outcome indicators - at the aggregate level - of areas with the facilities and areas that lack them, quite often neglecting systematic differences between treated and nontreated areas. Moreover, at aggregate levels, on the one hand, less comprehensive information may imply greater unobserved and uncontrolled heterogeneity; on the other, heterogeneity within areas may jeopardize identification of impacts. To account for these key observations, the authors used a propensity score matching (PSM) analysis at the individual level. Using indirect methods based on census data they constructed a mortality index at the motherhood level, and calculated five different impact estimators based on the propensity scores.

Gender and Social Inclusion Across the Sanitation Chain in Tamil Nadu – Assessment and Strategy. Indian Institute for Human Settlements, 2019. http://dx.doi.org/10.24943/gsiatnas10.2019.

Testo completo
Abstract (sommario):
The Government of Tamil Nadu (GoTN) has prioritised the full sanitation chain, including the strengthening of septage management as an economical and sustainable complement to networkbased sewerage systems. The Bill and Melinda Gates Foundation (BMGF) is supporting the GoTN to achieve the Sanitation Mission of Tamil Nadu through the Tamil Nadu Urban Sanitation Support Programme (TNUSSP). TNUSSP Phase I (2015-2018) was designed to support GoTN and selected cities in making improvements along the entire urban sanitation chain. In the second phase (2018– 2020), TNUSSP seeks to go one step further and integrate a gender and social inclusion (GSI) perspective within its interventions at two sites – the city of Tiruchirappalli (Trichy), and the two town panchayats (TPs) of Periyanaicken-Palayam (PNP) and Narasimhanaicken-Palayam (NNP) in Coimbatore district – along the urban sanitation cycle and in its support provided at the State level.

Testo completo
Abstract (sommario):
This paper assesses the welfare impacts of local investments projects in rural areas of Guatemala. Using census track data from two rounds of the Guatemalan population census, as well as administrative data on investment projects, the authors estimate the impact of education, sanitation, productive, and total investment activities at the village level on measures of welfare. This is the first impact evaluation of social funds in Guatemala, and also the first paper that uses village level data, and both a multi-treatment effect approach and the generalized propensity score with continuous treatments to analyze this type of interventions. The outcome is such that local investment in schools significantly boosts enrollment and investments in water and sewerage significantly improved measures of access to water. The authors also examine the welfare impacts in regards to infant mortality and school progression.

Ruprah, Inder J., e Luis Marcano. An Impact Evaluation of Chile's Progressive Housing Program. Inter-American Development Bank, giugno 2008. http://dx.doi.org/10.18235/0011136.

Testo completo
Abstract (sommario):
This paper presents the findings of an evaluation of Chile's Progressive Housing Program (PHP), which is a public housing program that finances the purchase of a new house for lower income households. The evaluation finds that the programs' package (savings requirement, voucher and mortgage) design is inappropriate if the program is targeted to the poor. In fact the pro-poor targeting of the program was poor with high under-coverage and high leakage. Furthermore, the benefit of a minimum quality new house was not sustainable as many households slipped back into the housing shortage category overtime. This impact evaluation reveals that although the program had significant positive effects on materiality conditions (access to water, sewerage, and electricity), it had a negative effect on overcrowding, and had no discernible effects on welfare indicators (poverty, school attendance, occupation ratio).

Testo completo
Abstract (sommario):
This study explores the state of infrastructure in the region's primary education schools, using the SERCE database, and analyzes the connection between school infrastructure conditions and language and mathematics tests results for third and sixth grade students. The results of the analysis indicate that school infrastructure and the access to basic services (electricity, water, sewerage and telephone) in the region's schools are highly deficient; there exists a large disparity between countries as well as between private urban, public urban and public rural schools; and there are large gaps between schools with children from high income families and schools with children from low income families. The analysis on the relationship between school infrastructure and academic results in the SERCE tests indicate that the highest factors most significantly associated with learning outcomes are: the presence of spaces that support teaching (libraries, science and computer labs); the connection to electric and telephone utilities; access to potable water, drainage and bathrooms. This indicates that countries in the region must strengthen investment geared towards improving school infrastructure in order to close the gaps that negatively affect rural areas, public sector schools, and schools with students from low income families. Likewise, public policies must prioritize infrastructure areas that have an impact on learning.

Testo completo
Abstract (sommario):
The present paper explores the relationship between political competition and effective public goods delivery systems in a decentralized context to study whether the awareness generated through such a competitive environment and the existence of more political options are a part of the causal mechanisms for effective governance. In particular, we want to observe the effect of electoral competition on the incentives to build fiscal capacity and provide public goods such as education and water, that are to a large extent the responsibility of the local municipalities. The research hypothesis is that political competition strengthens the decentralized municipalities through building their local fiscal capacity. In turn, the fiscal capacity is the fundamental variable that explains the differences in sector performance across local governments. Local fiscal capacity brings about better policy outcomes, as well as a better match between resources and the needs - what we call responsiveness - which simultaneously ensures greater efficiency in local spending. Using a rich panel municipal dataset from 1994 till 2009, we have shown that on comparing the differences across education and the water and sewerage sectors, the power of fiscal effort appears to be the driving force behind better policy outcomes than any other resource commonly made available to the municipalities, such as national transfers or royalties.
