Delhi need complete review of DJB corrupt and scammed functioning since 1950. It is difficult for State to imagine how Incompetence & Corruption has harmed Delhi residents.
Rooftop Water Tanks is standard all over Delhi – earlier Rooftop Tanks of 250 L Capacity for water for Toilets and to BALANCE between water supply & demand. CPWD Flats being built had 1000 L per flat rooftop storage in 1978 when Morarjee Desai made a surprise visit and present President honorable Ram Nath Kovind was his assistant.
Most Developed Countries USA, EU, Japan, Canada etc have no Rooftop Water Tank, no UG Tank, Water Supply is 24 Hour Under Good Pressure & Fire Hydrants every 500m.
1. Hard Water Supply: – Soon after construction started in Hauz Khas, in 1964 a 40 HP Deep Well was installed which supplied 40 GPS of Un-potable Hard water just in front of Sirifort Auditorium – Thousands are operational including Home Tube-wells and we continue to suffer though it is now diluted with fresh water. Earlier there was no choice – now people who can afford RO use them regularly that waste around 100 LPD in purification process and cost Rs.5000/- as O&M each.
2. Zero Pressure Water Supply: – Line Pressure started to fall, from 1972 and Tail-Endconsumers started building High Capacity Under Ground Tanks with Booster Pumps.
3. Contaminated Water Supply Under ZERO Pressure: – From 1981 onward Water Pressure was Zero as Consumers installed INLINE BOOSTER PUMPS – there was no Chlorine in Water Supplied and Contaminants were SUCKED in and to protect against it gradually consumers Installed Water Purifiers also.
Rooftop Water Tanks vs XTRA Light Structure FLOOR & 5KW SolarPV
4. Load of Water Tanks on Roofs could be 5 Tones to 15 Tones and Load on Ground due to Underground Tank additional 10 Tones on average. Owners are deprived of A Light Structure Floor and have 5 KW SolarPV producing 8-9 Units of power daily.
Sources of Waters
5. RIVER WATERS SUPPLIES CONTAMINATED: – Delhi get Sutlej, Yamuna & Ganga Water Supplies as primary sources – Water quality at Take Up points is VERY GOOD to EXCELLENT but Delhi get 50% Yamuna Water from River in Delhi where it is most contaminated. Delhi should get Yamuna Share from Tajewala Headworks.
6. INSIST ON RAPID BUILDING OF STORAGE DAMS – KISHAU, LAKHWAR-VYASI, and RENUKA: – This will ensure GOOD QUALITY 24×365 Water Supply minimize Cost Maximize Capacity or Existing Water Treatment Plants.
Economic Loss Over 5-6 Decades: –
1. Rs.10,00,000 Cr for Rooftop Floors could have been built instead of Water Tanks,
2. Rs.10,000 Cr per year Health Care Cost,
3. Rs.10,000 Cr per year as Cost of Pumping, O&M of Purifiers, Depreciation on Water Supply and Lost SolarPV Opportunity.

CM Kejriwal wants water audit, DJB to go for flow meters
NEW DELHI: To gather real-time data on loss of water in the distribution network, Delhi Jal Board plans to install flow meters on primary and secondary underground reservoirs. Concerned at the extensive water loss and the fact that no water audit has ever been carried out by DJB, chief minister Arvind Kejriwal asked the water board to put in place a mechanism for collection of data on water losses.
Delhi has an installed capacity for the supply of 903 million gallons a day, and while there are no definitive figures for water loss during transmission and distribution, it is estimated to be a bit over 45%. The CM sees this as a major concern in the water situation. After taking over as chairman of DJB in September, Kejriwal realised to his shock that a massive amount of water was lost due to leakage, theft and other reasons.
At a review on Friday, Kejriwal is learnt to have directed the installation of flow metres at the earliest. According to sources, DJB has told the CM that installation of permanent meters would take 6-10 months, so for now clamp meters would be installed to determine the causes of the water loss.
The matter was apparently also discussed at length in the quarterly review of the state government’s outcome budget indicators and targets held in July-August.
DJB intends to begin the process with around 600 underground water reservoirs, which will require 2300 flow meters. However, the meters will be installed only temporarily at the underground reservoirs to collect data over a few days. On the basis of the findings, a plan to check water losses will be determined. To enable this assessment, DJB called for companies to bid for installing the flow meters, and at least seven parties have shown interest. The water board is also learnt to be working on installing permanent flow meters.
This is not the first attempt of DJB at a mechanism to track and record water losses. Kejriwal was apparently informed at the outcome budget review that earlier tenders for bulk supply of flow meters had failed to evoke response. According to DJB officials, a significant amount of distribution losses happen at the stage of the water reaching the household because the pipes at this point are often neglected and unrepaired. The flow meters, though planned at the underground reservoir stages, are expected to provide concrete indicators of where the most water losses occur, sources said.
The current system takes the city’s water through 10 water treatment plants to 117 primary reservoirs and from there to 500 secondary reservoirs. It is from here that the water is supplied to consumers. The figure of 45-50% loss of supplied water is based on feedbacks and estimated capacities. The use of flow meters will make it possible to track the actual losses.
Reliable sources told TOI that DJB has informed the CM that in the last few weeks, its executives have discovered 3,000 instances of illegal tapping of its supply lines. “The possibility of more illegal tappings is high,” a source said.
