Explanation:
Delhi's two main surface water sources are the Yamuna and Ganga which, officials said, account for around 90% of the water supply. The remaining is covered by ground water.
Answer:
After water is treated in the plant, it is released into the DJB water pipeline network stretching over 13,000 km. It first reaches a primary underground reservoir (UGR), a reinforced concrete water tank of a large capacity where water is supplied 24×7. However, a DJB officer revealed that while changing pipelines a few years ago, around 200 direct consumer connections were found in between water treatment plants and the primary UGRs — something that is now prohibited. The department now keeps a track of the amount of water received and supplied with 2,200 flow meters installed across its network.
From the primary UGR, water is either supplied directly to colonies based on a fixed time schedule, or is sent to a secondary UGR and in rare cases, a tertiary UGR, which cater to single or a group of colonies. Together, there are nearly 500 UGRs in Delhi. The water pipelines pass in front of houses and it is the responsibility of consumers to apply to the DJB for a connection, officials said. A DJB engineer then assesses the site and recommends how the connection can be made with the help of a DJB licensed plumber
