The Haryana State Pollution Control Board on Wednesday issued a notice to the Unitech Fresco residental apartments in Sector 50 over the lack of a functional sewage treatment plant (STP) in the society.
The pollution watchdog conducted an inspection of the society earlier this week and collected samples. The samples failed the test. The HSPCB has since asked the residents to set up an STP plant and also explain the reason for not having one since the last one year.
Owing to the absence of the STP, the sewerage water line is connected to the rainwater pits, thus contaminating the groundwater, said an official at HSPCB.
“The test results were not satisfactory and we have asked the society to fix the problem within a week. We will take action against them if they fail to submit a compliance report,” said Bhupender Singh, regional officer, HSPCB.
The HSPCB officials further said that the setting up of sewage treatment plants (STPs) has been mandated in line with global standards of treating effluent discharge by such plants.
It has been made mandatory by the pollution watchdog to install STPs for large societies in the city. Releasing untreated waste water to natural drains is prohibited, as it leads to contamination of the groundwater and water bodies.
The new norm which was notified last year in November requires installation of modern filtration systems and ensure zero-bacteria discharge into the rivers. According to the HSPCB, untreated domestic sewage accounts for about 80% of water pollution in the city.
The city lacks adequate sewage treatment and municipal solid waste processing facilities.
Earlier, the residents had also lodged a complaint with the HSPCB on the issue. Nilesh Tandon, president, RWA, said, “This is a serious issue, as contamination of the groundwater by untreated waste could lead to health hazards as well.”
A Unitech spokesperson said, “We are working on the issue and will soon submit compliance report.”
