The Indira Gandhi International Airport and its neighbouring villages will finally get a proper outlet for sewage and storm water,with the Delhi Jal Board (DJB) in the process of constructing a 10 MGD sewage treatment plant (STP) at Kapashera. The project will be completed by June this year.
Sewage pipelines are currently being laid around six villages around the airport Mehram Nagar,Mahipalpur,Samal Khan,Shahbad Mohammadpur,Bijwasan and Kapashera to collect sewage and transport it to the Kapashera STP. A 10-km storm water drain is also being constructed around an area of 5,000 acre to transport rain water from the airport to the Najafgarh drain.
The DJB also plans to generate revenue from the project by auctioning treated water from the STP to private parties that are slated to develop the airports much delayed hospitality district.
The STP under construction at Kapashera is being built with superior technology to treat wastewater following the treatment of sewage. We will advertise and sell the treated water for purposes such as irrigation and cooling of AC plants, DJB CEO Ramesh Negi said.
These processes require a large amount of water and put an undue strain on groundwater resources.
Our aim is to save groundwater and at the same time generate revenue. Expressions of interest will be invited from private developers soon, Negi said.
Delhi International Airport Limited (DIAL) is in the process of assessing bids from realty developers for the 45-acre airport hospitality district project,and DJB plans to target these parties for the bids,which will be announced in the coming week.
Tackling IGIs sewer problems
Drainage has been considered one of the major problems plaguing the new runway at the IGI airport. The runway has a gradient of about 16 feet,with the NH-8 end being higher. As a result,while there is no water-logging on the runway,rainwater gets accumulated on the Dwarka side.
One of the reasons cited for the frequent bird hits,a regular feature at the airport and the new runway,is the large number of houses overlooking the runway,along with garbage dumps and drains in the nearby areas that attract birds. Airport sources said the problem worsens in the absence of an outlet to discharge the accumulated water,which also attracts birds.
The stormwater drain around the airport is one of the two major projects underway at the Delhi Airport,the other one being the Kapashera STP. The drain will prevent the new runway from getting flooded during the rains, Delhi Chief Secretary Rakesh Mehta said.
The project is being built at an estimated cost of Rs 250 crore,Mehta said. Phase I of the project,in which 5.5-km stretch of the drain will be constructed,will be finished by June 2009.
The entire project will be completed by the middle of 2010,Mehta added.
