To survive the intense heatwave, the Delhi government has planned to implement a dual pipeline network for all residential and official buildings. The infrastructure aims to feed buildings in two separate lines, one for scarce drinking water and the other for carrying treated recycled water to keep Delhi running without draining its primary reservoirs.
What's The Plan?
The capital receives approximately 650 MGD of treated water from 37 STPs. Of this, approximately 105 MGD is used for irrigation in parks and sprinkling on roads.
The remainder is drained into the sewers. To utilise this, the Delhi Jal Board will lay pipelines to supply water to DDA and MCD parks near the Sewage Treatment Plant (STP).
The Delhi Jal Board has issued the tender to lay pipelines for delivering treated STP water to 74 identified parks larger than one acre. A sum of Rs 90 crore has been approved for the project.

The STP water can be utilised for construction work, government, commercial, and domestic non-potable water purposes. The project will provide around 1,000 MGD of water to the Delhi residents.
Test Before Installation
Deputy Chief Minister of Delhi, Parvesh Verma, claimed that the work has been initiated to upgrade the STPs. He stated that the treated water has a biological oxygen demand (BOD) of 10. BOD is primarily used as an indicator of water pollution. Higher BOD values refer to the water being more heavily polluted, which can deplete oxygen levels and harm aquatic life. The current BOD is suitable for construction.
Along with setting up modern technology STPs for domestic use, a double pipeline system will be provided in government buildings, commercial establishments, and houses.

The authorities will conduct a feasibility test before installation. The pipelines will initially be implemented in government buildings. Over time, it will then be expanded to hotels, commercial establishments, group housing societies, and large residential complexes. Incentives are also being considered for institutions and societies that adopt this system.
