The NGT directed the Chief Secretary, Delhi in coordination with the concerned authorities, including the DJB and the DDA to take further action on the subject of restoration of water bodies, installation of RWH systems, utilisation of treated sewage water, extraction of ground water and prevention of contamination of water.

Further, the Delhi government and all other states/UTs as well as Central Monitoring Committee (CMC) should explore "whether a model can be developed as a strategy for augmenting supply of drinking water by linking water collected through RWH systems to the water supply systems on the pattern of schemes for connecting solar energy generated in individual houses with the Grids with requisite incentives to motivate the concerned individuals/organizations", the NGT order of January 22, 2021 said.
