Delhi Sewage Plan Hits Forest Land Hurdle
6 Apr
Summary
- DJB seeks forest dept permission for sewage network development.
- Unauthorised colonies on forest/ridge land face sanitation issues.
- DJB assures no tree cutting in proposed sewer line project.

The Delhi Jal Board (DJB) has requested permission from the Delhi forest department to construct sewage networks in unauthorised colonies located on forest or ridge land. This move is intended to address environmental degradation and enhance sanitation in these critical areas, which often lack proper sewered infrastructure.
The DJB's proposal emphasizes the urgency of the situation, highlighting the mandate to provide sewage services across Delhi. Specifically, the board requires approval to intercept and divert sewage from colonies situated on government forest land. These proposed works are deemed essential public utility services aimed at preventing pollution of the Yamuna River, aligning with directives from the National Green Tribunal (NGT).
Several areas, particularly in South Delhi, have unauthorised colonies on forest and ridge land, including parts of Sangam Vihar and Sainik Farm. The DJB has committed to laying sewer lines underground, ensuring no trees are cut. The proposal awaits a No Objection Certificate or specific discharge location guidance from the Delhi Ridge Management Board.
Currently, 82% of Delhi is covered by sewage networks, with 18% remaining, predominantly unauthorised colonies and JJ clusters. Out of 1,799 unauthorised colonies, many still await sewer line plans or require clearance from departments like the forest department.
