DDA Plans STPs to Irrigate 750 Parks with Treated Water

23 May 2025 CW Team

The Delhi Development Authority (DDA) is set to construct its own sewage treatment plants (STPs) under a new water management initiative designed to supply treated water for irrigation across 750 green spaces, including parks, forests, riverfronts, and golf courses spread over 10,000 acres.

Currently, the DDA relies on water tankers or pipelines laid by the Delhi Jal Board (DJB) to supply treated water to its green spaces. However, under the proposed plan, the authority aims to establish self-sufficient systems, reducing its reliance on external agencies and improving cost-effectiveness.

“Some parks are connected to DJB STPs via pipelines; others rely on water tankers. We now want a unified system,” a senior DDA official said. The authority will appoint a consultant to prepare a detailed project report covering design, technology, and operational aspects of the initiative.

DDA data shows a daily requirement of approximately 34 million litres of water for maintaining all its parks and green zones. The proposed consultant will be tasked with assessing current water demand, mapping available sources of treated water, and designing suitable STPs.

The comprehensive plan will include capturing raw sewage, selecting treatment technologies, and ensuring a continuous supply of treated water for irrigation.

The initiative aligns with National Green Tribunal directives to minimise groundwater extraction and prioritise the use of treated wastewater for horticultural purposes. The DDA’s move is expected to enhance irrigation efficiency, reduce operational costs, and ensure the long-term sustainability of Delhi’s urban green cover.
