Delhi's daily water demand is enormous, but supply is insufficient. There's a significant gap between water needs and availability. Furthermore, the water reaching the public isn't being properly tested. Standards require multiple tests, but in many places, only a few are being conducted. Due to a lack of staff and modern equipment, water quality cannot be accurately assessed.

The audit also revealed that in many areas, water is being supplied without purification. Water from borewells and other sources is often supplied without treatment. Drinking such water can be extremely hazardous to health. It may contain bacteria, dirt, and harmful chemicals that can cause a variety of diseases.

Delhi has thousands of kilometers of pipelines for water supply. Many of these pipelines are very old and in poor condition. Leaks in old pipelines can cause water to be wasted along the way. Furthermore, cracks in pipelines can cause dirty water to mix with clean water, contaminating the water and making it unsafe for people to access their homes.

Stomach and intestinal infections are also caused by bacteria present in dirty water. Bathing in or using dirty water can cause itching, rashes, and fungal infections. Chemical contamination, such as arsenic or lead, in water can increase the risk of cancer, kidney, and liver diseases.
