The Delhi Jal Board has prepared and uploaded on its website the draft ‘Sewage Master Plan (SMP) 2031’, inviting suggestions and comments from various stakeholders before the plan is finalised.

“In an effort to provide enhanced waste water facilities in the city, the DJB has developed a draft integrated and sustainable SMP-31’, to develop a comprehensive and technically viable plan for the implementation of sewerage works within the NCT of Delhi, with support from a waste water management information system. This will also reduce pollution in river Yamuna,” a DJB spokesperson said.

The DJB had engaged international consultants to prepare the master plan in order to carry out an in-depth and exhaustive door-to-door survey of all areas with a sewer system as well as those which did not have any such facility.

During the process, 36 existing sewage treatment plants with a design capacity of 604 million gallons per day at 23 locations were audited.
In areas without a sewerage system — nearly 2,200 colonies —an extensive topo-survey and geotechnical investigation was undertaken. A waste water management information system was developed, which included development of an geographic information system (GIS) framework, integration and close-coupling of sewerage information on the GIS database to carry out hydraulic modelling.

“The Master Plan envisages laying of sewer lines in a length of about 10,500 km, which is a lengthy process. Hence, the work is to be carried out in a phased manner, prioritising areas where sewer lines can be made functional, immediately after being laid, because of availability of outfall sewers and waste water treatment plants,” the spokesperson said.

With the implementation of SMP 2031, sewerage facilities will be extended in the unplanned areas including the rural, the resettlement and the unauthorised colonies. The work of laying of sewer lines has already been completed in 135 unauthorised colonies and is in progress in 208 unauthorised colonies.

“Tenders for taking up work in another 80 colonies have either been approved or are under process of award,” the spokesperson said.
