Delhi Jal Board (DJB) is the government agency responsible for supply of potable water to most of the National Capital Territory region of Delhi, India. Delhi Jal Board was constituted on 6 April 1998 through an Act of the Delhi Legislative Assembly incorporating the previous Delhi Water Supply and Sewage Disposal Undertaking. DJB is also responsible for treatment and disposal of waste water.
In 2004, the DJB called on residents to use a bucket of water instead of shower in order to save water. [1] In July 2012, the Board decided the privatization of tanker management system in the city to check pilferage of water. [2] Most recently, vide Resolution No. 871 dated 27.08.2019, the DJB announced a complete waiver of water arrears for people living in colonies categorized as E, F, G and H (House Tax Categorization) and a rebate ranging from 25-75 per cent of the dues for consumers falling in the other four categories (A-D). [3] [4] After a history of non-implementation of Rainwater Harvesting (RWH) Systems in the city [5] , the Board has now mandated the installation of such systems in the city while setting a hard target for implementation. [6] The Board has also made attempts to incentivize RWH methods by proposing financial assistance for the construction of RWH systems providing rebates on the water bill to households which install such systems. [7] The Board has also proposed the imposition of fines on households not complying with the hard deadline of March 2020 for getting RWH systems installed. [8]
A 2007 article in Newsweek profiled a ten-year veteran sewer worker of Delhi Jal, in preparation for the 2007 World Toilet Summit in New Delhi. "The four-day event is exploring ways to bring sewage systems to the estimated 2.6 billion people in the world who don't have proper toilets, including 700 million in India alone."
The article carried the headline: "The world's worst job? Indian sewage workers are certainly in the running," adding that the 3,700 miles of existing sewer lines were in poor repair and had inadequate capacity to meet the needs of a growing population. [9]
Delhi Jal Board was found guilty of corruption in an effort to privatize itself when an investigation was conducted by Arvind Kejriwal and the non-governmental organization (NGO) Parivartan in 2005. [10] After submitting a Right to Information (RTI) request, Parivartan received 9000 pages of correspondence and consultation with the World Bank, where it was revealed that the privatization of Delhi's water supply would provide salaries of $25,000 a month to four administrators of each of the 21 water zones, which amounted to over $25 million per year, increasing the budget by over 60% and water taxes 9 times. [11] [12]
The Delhi Jal Board was first approached by Parivartan in November 2004, following a report by the newspaper The Asian Age , where the scheme was revealed to the public for the first time. [11] [12] The DJB denied the existence of the project, but after an appeal, the RTI request was granted. The documents revealed that the project began in 1998, in complete secrecy within the DJB administration. [11] [12] The DJB approached the World Bank for a loan to improve the water system, which it approved, and the effort began with a $2.5 million consultation loan. The Delhi government could have easily provided the money, and the interest rate of 12% that was to be loaned by the World Bank could have been raised on capital markets for 6%. [11] [12] Following the consultation, 35 multinational companies bid, of which six were to be shortlisted, out of which PricewaterhouseCoopers (PwC) was found to be unethically favored, and granted the contract in 2001. [10] [13] Following the investigation by Parivartan, a campaign was waged by Kejriwal, Aruna Roy, and other activists across Delhi, and the Delhi Jal Board withdrew the loan application to the World Bank.

Sewerage is the infrastructure that conveys sewage or surface runoff using sewers. It encompasses components such as receiving drains, manholes, pumping stations, storm overflows, and screening chambers of the combined sewer or sanitary sewer. Sewerage ends at the entry to a sewage treatment plant or at the point of discharge into the environment. It is the system of pipes, chambers, manholes or inspection chamber, etc. that conveys the sewage or storm water.
The Yamuna is the second-largest tributary river of the Ganges by discharge and the longest tributary in India. Originating from the Yamunotri Glacier at a height of about 4,500 m (14,800 ft) on the southwestern slopes of Bandarpunch peaks of the Lower Himalaya in Uttarakhand, it travels 1,376 kilometres (855 mi) and has a drainage system of 366,223 square kilometres (141,399 sq mi), 40.2% of the entire Ganges Basin. It merges with the Ganges at Triveni Sangam, Allahabad, which is a site of the Kumbh Mela, a Hindu festival held every 12 years.
Rainwater harvesting (RWH) is the collection and storage of rain, rather than allowing it to run off. Rainwater is collected from a roof-like surface and redirected to a tank, cistern, deep pit, aquifer, or a reservoir with percolation, so that it seeps down and restores the ground water. Rainwater harvesting differs from stormwater harvesting as the runoff is typically collected from roofs and other area surfaces for storage and subsequent reuse. Its uses include watering gardens, livestock, irrigation, domestic use with proper treatment, and domestic heating. The harvested water can also be committed to longer-term storage or groundwater recharge.
A combined sewer is a type of gravity sewer with a system of pipes, tunnels, pump stations etc. to transport sewage and urban runoff together to a sewage treatment plant or disposal site. This means that during rain events, the sewage gets diluted, resulting in higher flowrates at the treatment site. Uncontaminated stormwater simply dilutes sewage, but runoff may dissolve or suspend virtually anything it contacts on roofs, streets, and storage yards. As rainfall travels over roofs and the ground, it may pick up various contaminants including soil particles and other sediment, heavy metals, organic compounds, animal waste, and oil and grease. Combined sewers may also receive dry weather drainage from landscape irrigation, construction dewatering, and washing buildings and sidewalks.
First flush is the initial surface runoff of a rainstorm. During this phase, water pollution entering storm drains in areas with high proportions of impervious surfaces is typically more concentrated compared to the remainder of the storm. Consequently, these high concentrations of urban runoff result in high levels of pollutants discharged from storm sewers to surface waters.
The Bangalore Water Supply and Sewerage Board (BWSSB) is the premier governmental agency responsible for sewage disposal and water supply to the Indian city of Bangalore. It was formed in 1964.
Arvind Kejriwal is an Indian politician, activist and former bureaucrat, who is serving as the 7th and current Chief Minister of Delhi since 2015, after his first term in the post from 2013 to 2014.

In 2020, 97.7% of Indians had access to the basic water and sanitation facilities. India faces challenges ranging from sourcing water for its megacities to its distribution network which is intermittent in rural areas with continuous distribution networks just beginning to emerge. Non-revenue water is a challenge.
Chennai is located at 13.04°N 80.17°E on the southeast coast of India and in the northeast corner of Tamil Nadu. It is located on a flat coastal plain known as the Eastern Coastal Plains. The city has an average elevation of 6 metres (20 ft), its highest point being 60 m (200 ft). Chennai is 2,184 kilometres south of Delhi, 1,337 kilometres southeast of Mumbai, and 1,679 kilometers southwest of Kolkata by road.
Microcredit for water supply and sanitation is the application of microcredit to provide loans to small enterprises and households in order to increase access to an improved water source and sanitation in developing countries. While most investments in water supply and sanitation infrastructure are financed by the public sector, investment levels have been insufficient to achieve universal access. Commercial credit to public utilities was limited by low tariffs and insufficient cost-recovery. Microcredits are a complementary or alternative approach to allow the poor to gain access to water supply and sanitation.
The ancient Indus Valley Civilization in the Indian subcontinent was prominent in infrastructure, hydraulic engineering, and had many water supply and sanitation devices that are the first known examples of their kind.
Chennai Metropolitan Water Supply and Sewerage Board, known shortly as CMWSSB, is a statutory board of Government of Tamil Nadu which provides water supply and sewage treatment to the city of Chennai and its metropolitan region.

Rainwater harvesting in the United Kingdom is a practice of growing importance. Rainwater harvesting in the UK is both a traditional and reviving technique for collecting water for domestic uses and is generally used for non-hygienic purposes like watering gardens, flushing toilets, and washing clothes. In commercial premises like supermarkets it is used for things like toilet flushing where larger tank systems can be used collecting between 1000 and 7500 litres of water. It is claimed that in the South East of England there is less water available per person than in many Mediterranean countries.
Parivartan (Transformation) is a grass-roots activism organisation based in the Sundar Nagari area of New Delhi, India. During the 2000s, Parivartan used Right to Information (RTI) to address citizens' grievances related to Public Distribution System (PDS), public works, social welfare schemes, income tax and electricity. By 2012, Parivartan was largely inactive, and its main leaders Arvind Kejriwal and Manish Sisodia had launched a political party - the Aam Aadmi Party.
Water scarcity in India is an ongoing water crisis that affects nearly hundreds of million of people each year. In addition to affecting the huge rural and urban population, the water scarcity in India also extensively affects the ecosystem and agriculture. India has only 4% of the world's fresh water resources despite a population of over 1.4 billion people. In addition to the disproportionate availability of freshwater, water scarcity in India also results from drying up of rivers and their reservoirs in the summer months, right before the onset of the monsoons throughout the country. The crisis has especially worsened in the recent years due to climate change which results in delayed monsoons, consequently drying out reservoirs in several regions. Other factors attributed to the shortage of water in India are a lack of proper infrastructure and government oversight and unchecked water pollution.
The coastal city of Chennai has a metropolitan population of 10.6 million as per 2019 census. As the city lacks a perennial water source, catering the water requirements of the population has remained an arduous task. On 18 June 2019, the city's reservoirs ran dry, leaving the city in severe crisis.
