Gurugram, Nov. 26 -- Residents of Imperia Esfera in Gurugram's Sector 37C have raised concerns over a leakage in the sewage treatment plant (STP) of their society near the entrance gate. The STP, which should have been properly covered, is lying open, and the leakage is emitting a strong foul odor. Residents say the stench is causing significant discomfort and posing potential health hazards. "Our society was developed in three phases in 2018. During phase 1, the builder had said the STP near the entrance was temporary and would be shifted to the basement in phase 2. However, nothing has been done so far. The current STP location isn't even approved, and despite our requests, the builder has not provided any documentation," said Rinky Singh, RWA president of Imperia Esfera. Residents said the builder is yet to hand over the society to the RWA. In July this year, Real Estate Regulatory Authority (RERA) directed that the handover of common areas should be completed. "Before the handover, we had all assets audited by a professional auditing company to ensure they were in proper working condition. However, the audit revealed that many assets were not up to standard," said Rinky Singh, adding that the report also found that the STP is beyond repair and requires urgent replacement. "The situation is so bad that every time we pass by, we have to cover our mouths and noses. Since eight years, there has not been a single repair of the STP," said Shiv Shankar Maurya, RWA vice president. "We raised our concerns with the Haryana State Pollution Control Board (HSPCB) on Tuesday. They shared that they will speak with the builder." Harsh Pushkarna, vice president of Pragati Associates, the agency appointed by Imperia Structure Limited for Imperia Esfera, said, "The society was handed over to the RWA in June this year. Since then, the STP has been the RWA's responsibility. They could have had it properly covered by now."
