This study examines the presence of pollution of Yamuna in the city of Delhi, from two perspectives: (i) understanding the concept of trapping drains and (ii) establishing small scale Sewage Treatment plants at the point of outfall. With events occurring over the last century making river Yamuna polluted, the study focuses on the latest methods and technologies available to avoid intermixing of sewage and storm water drains to reduce pollution. Due to mixing of storm water and sewage, the desired qualities of the river water get degraded and the amount of dissolved oxygen decrease considerably. If this water is allowed to pass through a sewage treatment plant then it will lead to increase in time of treatment due to increase in discharge. The increased discharge can also affect the efficiency of the treatment plant. The study also includes the theory of tributaries of river Yamuna, Major Drainage problems in the region, Quality of River water.

In many nations, watershed development is a critical component of rural development and natural resource management initiatives. A watershed is a kind of common pool resource that consists of a geohydrological unit that drains to a common location through a series of drains. All regions on the planet are part of one or more watersheds, and even small land fragments act as watersheds (for this purpose a case study on VILLAGE SIRASPUR, DELHI is also a part of MICROWATERSHEDS IN DELHI). Watershed management is problematic because watershed systems include a variety of competing uses, thus any gain or cost will be distributed unevenly across users. Theories based on common research suggest that managing complex watersheds would be challenging, and that success will be restricted to isolated, actively aided micro watershed programmes with a social organisation emphasis. The simplest way to encourage community action is at the micro watershed level, yet good hydrological management necessitates effort at the macro watershed level. It also helps in recharging groundwater which is depleting in Delhi at alarming rate.

The rapidly growing urbanization has resulted in increased environmental pollution and degradation that has equally affected the quality of air and wastewater. Urban drains that carry wastewater from households and industries are also carrying loads of pollutants. The current study was conducted to compare the trend in the concentration of particulate matter (PM) in the air, across the seasons near the urban drains in Delhi, a metropolitan city. The air samples were taken from Najafgarh drain, which is the biggest drain of Delhi city and has a contribution of about 60% of the total wastewater released from Delhi city into river Yamuna. The Indian Standard method IS 5182 Part 24:2019 was used for PM2.5 & IS 5182 Part 23:2006 was used for PM10 monitoring and analysis. The results of the analysis showed that the variation in particulate matter (PM) is observed with changes in relative humidity and with seasonal changes. The variation in PM2.5 levels was seen in a range of 55.30-118.42 μg/m3 from June 2020 to February 2021 & in PM10 levels were seen in the range of 77.54-261.99 μg/m3 during June 2020 to February 2021 for location L1. The variation in PM2.5 levels was seen in a range of 23.84-76.94 μg/m3 from June 2020 to February 2021 & in PM10 levels were seen in the range of 42.06-149.48 μg/m3 during June 2020 to February 2021 for location L2. Few studies have shown that contaminants can enter into the fresh air from the municipal wastewaters and open drains.

When the river Yamuna leaves the National Capital Territory of Delhi, its situation further deteriorates. Despite accounting for only 1% of the river’s overall catchment area, this region is responsible for more than half of the pollutants discovered in the Yamuna. The river Yamuna, on the other hand, is Delhi’s only natural resource for maintaining all forms of life. The Yamuna River is currently experiencing a significant level of pollution problem, and in order to control pollution in the Yamuna River, continual analysis is essential. The Yamuna River is contaminated by the discharge of untreated municipal sewage and industrial effluent through seven major drains: Najafgarh, Yamunapur, Sen Nursing Home, Barathpula, Maharani Bagh, Kalkaji, and Tuglakabad. In terms of people and chemicals, continuous sampling takes time and money. The primary objective of this study is to analyse the wastewater samples collected by sub-drains and STP’s to predict the pollutant transportation in river Yamuna from Najafgarh Drain. The study focusses on the only pollutant, i.e., Biochemical Oxygen Demand from the starting point to after the confluence of Najafgarh Drain into river Yamuna. The prediction is to be done by using MATLAB software. This study would help to identify the main sources of sub-drains which are polluting Najafgarh Drain and eventually the river Yamuna. This shows how MATLAB may be used to calculate the pollution load caused by organic waste in the Yamuna River as it flows through Delhi, India’s National Capital Territory. The model numerically solves a series of differential equations to simulate the dissolved oxygen and biochemical oxygen demand parameters in two dimensions. MATLAB is an interactive programming language that may be used to develop algorithms, graphics, and user interfaces in other computer languages. MATLAB helps estimate future water quality using present data, which saves time, labour, and other costs associated with the continuous study. There are various software programmes available in the market for predicting river water quality, however, MATLAB GUI provides an accessible and convenient user interface (Graphical User Interface).

The river Yamuna is considered a crucial river in the Indo-Gangetic plain. Having 0.4 Percent of the catchment area in the National Capital Territory (NCT) of Delhi, it feeds about 70 per cent of the population of Delhi and hence, is a major source of dependency for NCT of Delhi. The water quality monitoring of River Yamuna is done by the Delhi Pollution Control Committee (DPCC), Delhi on monthly basis.The objective of the study is to investigate the water quality of the river in the Delhi stretch, for the period 2003-2021. The water quality data has been derived from experimental analysis at DPCC across seven monitoring stations and has been analysed in the present study. It has been revealed that pollutant load from urban local bodies and drains have a stronger impact on the water parameters after the Wazirabad in Delhi, resulting in deteriorated water quality and high-Water Quality Indices (WQI). Water Quality Index (WQI) for the year 2021 indicates that pollution in the river Yamuna increases during monsoon and post-monsoonperiods while during pre-monsoon it remains relatively low.The average pH of the river water ranges from 6 to 8 throughout the year. The comparative data reveals that dissolved oxygen (DO) at most of the sites (except Palla) is nil and, the values of BiochemicalOxygen Demand(BOD) and Chemical Oxygen Demand (COD) have been increasing tremendously, which is due to the unregulated discharge or dumping of sewage water from urban local bodies (ULB) in the river.

Background. Industries such as electroplating, mining and battery production are major sources of heavy metal-rich waste entering nearby water bodies. Irrigation with heavy metal contaminated water can deteriorate soil quality as well as agricultural produce and have further toxic effects on human health. Objectives. The objective of the present study was to estimate the concentration of hazardous heavy metals such as chromium (Cr), cadmium (Cd), copper (Cu), nickel (Ni), zinc (Zn) and lead (Pb), as well as physico-chemical variables (pH, electrical conductivity, total dissolved solids, chemical oxygen demand and dissolved oxygen) at sampling locations along the Najafgarh and Loha mandi drains in Delhi, National Capital Region, India. Methods. The present study evaluated the quality of wastewater from the Najafgarh and Loha mandi drains, which are used for irrigational purposes in the Delhi region. Drain water quality was monitored for a period of 2 years for physico-chemical variables (pH, chemical oxygen demand, electrical conductivity and dissolved oxygen) as well as heavy metal concentrations (Cr, Cu, Cd, Zn, Ni and Pb). The two-year monitoring period (July 2012–March 2014) was chosen to represent three seasons: pre-monsoon, monsoon, and post-monsoon. Results. Varied concentrations of multiple heavy metals were found due to the extensive discharge of untreated industrial effluents into the drain water. Punjabi Bagh of Najafgarh drain was the most contaminated sampling site with the maximum concentration of Zn (12.040 ± 0.361 mg L−1), followed by Cr (2.436 ± 0.073mg L−1) and Cu (2.617 ± 0.078 mg L−1). Conclusions. Consumption of heavy metal-contaminated agricultural products can cause deleterious human health effects, leading to further health problems. The presence of multi-heavy metal ions above the Food and Agriculture Organization of the United Nations (FAO) permissible limits indicated that drain water was not suitable for irrigational purposes, and adequate measures are required to remove the heavy metal load from drain water. Competing Interests. The authors declare no competing financial interests.

Water Sensitive Planning (WSP) recognizes the centrality of water in the urban built environment, something often overlooked in urban planning systems. WSP was primarily developed for western city contexts but many cities in the Global South are rapidly urbanizing, and informal settlements are the predominant form of development, with limited existing water provision. A new WSP framework is needed for these contexts. This paper envisions what a WSP theory would look like for a city in the Global South to enhance water security, using Delhi as a starting point. Firstly, the substantive components of WSP are identified from the literature. Secondly, this framework is critiqued with respect to the extent to which it is appropriate for planning rapidly urbanizing cities, especially in India. Finally, the key principles of WSP for cities in the Global South are suggested. Notable principles include integration of water planning and city planning; linking of drains with statute protected water bodies; green places as recharge areas; reuse of adequately treated wastewater for irrigation purposes; and building roads and drains as per hydrogeography of a place.

Storm water drainage is meant to carry storm water (rain water) and any other clean surface water. It is fundamentally not suitable or designed for carrying sewage or industrial waste water or even septic tank effluent. Even the effluent from the sewage treatment plant cannot be discharged into it. Therefore, one of the urgent tasks should be to make plans for diversion of all waste water (both domestic and industrial) from surface drains.

Abstract: Increase in human population increases the need for energy. Sustainable energy production is gaining importance day by day. At the same time rapid urbanization and industrialization combined with improper town planning has led to the destruction and death of nearby water bodies. Discharge of drainage water without aeration or any other treatment in Metropolitan Indian cities such as Delhi, Mumbai, Nashik and all others have to led to the blackening of water sources. Indian city drains handle sheer volumes of water every day. A new method of aerating water combined with power generation could go a long way in solving the problem of water treatment as well as power generation. Even under low head this much amount of water if efficiently utilized can generate sufficient power not only for the plant but also for the grid. By using the power of water in vortex flow under gravity, an attempt is made to make power from Indian drains. To generate electricity, water must be in motion. This is kinetic (moving) energy. When flowing water turns blades in a turbine, the form is changed to mechanical energy. The vortex is a form of kinetic energy storage by which water under motion is trapped in a dynamic way. This increased amount of kinetic energy that gets trapped inside a vortex boosts the power inside a vortex.

This investigation looks at the nearness of contamination of Yamuna in the city of Delhi, from
two viewpoints: (i) understanding the idea of catching channels and (ii) setting up little scope
Sewage Treatment plants at the purpose of outfall. Getting channel alludes to the catching of 22
depletes legitimately streaming into the waterway Yamuna while setting up of little extension
sewage treatment plants would prompt reduction in contamination in the stream. With occasions
happening throughout the only remaining century making stream Yamuna dirtied, the
investigation centers around the most recent techniques and advancements accessible to abstain
from intermixing of sewage and tempest water channels to lessen contamination. Because of
blending of tempest water and sewage, the ideal characteristics of the waterway water get
corrupted and the measure of broke down oxygen decline impressively. In the event that this
water is permitted to go through a sewage treatment plant, at that point it will prompt increment
in time of treatment because of increment in release. The investigation likewise incorporates the
hypothesis of tributaries of stream Yamuna, Major Drainage issues in the locale, Quality of River
water, Water quality issues in Yamuna River and main sources of pollution in River Yamuna.
The examination remembers the investigation of fourteen significant channels for the territory of
Delhi where channels were legitimately streaming into the waterway Yamuna. Out of the
fourteen channels, three primary channels are key supporters of contamination which are
Najafgarh channel, Supplementary channel and Shahdara channel. The examination likewise
incorporates the investigation of the particular areas where sewage was getting blended in with
storm water. The sewage was being siphoned to storm water channel which arrives at waterway
Yamuna along these lines expanding the poison fixation in the waterway. The sewage was being
siphoned with the assistance of streetcar into the tempest water channel and there were for the
most part 39 such areas. After the review of all the individual areas it was reasoned that the work
for the restoration of waterway Yamuna is still in running stage and a great deal of
work despite everything should be done. Proper catching of the sewage was not being done
vi
because of inappropriate/helpless activity and support and furthermore checking of stream was
not done. It is prescribed that it will be smarter to give decentralized treatment of sewage at the
outfall itself in this manner diminishing contamination level in the waterway stream. Despite the
fact that the advancement has expanded quickly with the expanding time however there's still
parcel to be checked and worked.
