Large wastewater reuse scheme planned for part of Delhi
Reuse of 40 MIGD (182,000 m³/d) of wastewater for direct non-potable or indirect potable uses will be provided for 3-4 million people in Delhi, India, under a partnership led by consultant CH2M Hill.Together with PUB, Singapore's water agency, and Singapore Cooperation Enterprise, CH2M Hill will provide recycle and reuse facilities in the Coronation Pillar area for the Delhi Jal Board (DJB).
The DJB programme proposes to provide an in-depth understanding of the benefits and challenges of an integrated and holistic water management framework. It will also outline implementation and operation of sewage and wastewater recycling and reuse-related infrastructure projects, including delivering projects on a public-private partnership (PPP) basis.
Under Phase 1, the team will develop a recycle and reuse strategic plan, feasibility study and preliminary design, as well as a PPP framework for the Coronation Pillar Water Reclamation Plant. The programme will also conduct a series of workshops to build capacity for 90 government officials from the Delhi Jal Board.
During Phase 2, a tender document will be developed to invite bids on a DBFOT (Design Bid Finance Operate and Transfer) basis. Singapore-based Temasek Foundation, a philanthropic organization aimed at developing a prosperous, stable and connected Asia through developing human and social capital, is providing 70% of the funding as grant needed for Phase 1.
The population of Delhi, the capital of India, has increased from 9.4 million in 1991 to 16.3 million in 2011 with an ever-increasing pressure on the existing water resources.
