Noida Sewage Woes: STPs Fail, Wetlands Polluted
22 Nov
Summary
- One sewage plant non-operational due to flood damage.
- Wetlands show elevated pollutants, partly due to rain.
- Untreated sewage from Khoda continues to pollute drains.
Recent joint inspections by the Central Pollution Control Board (CPCB) and Uttar Pradesh Pollution Control Board (UPPCB) have uncovered critical issues with sewage treatment infrastructure in Noida. One significant sewage treatment plant was found non-operational due to damage from floodwaters, necessitating the diversion of its load to an adjacent facility. While other operational plants were assessed, wetlands developed on Noida drains exhibited elevated pollutant levels at their outlets, a situation exacerbated by recent heavy rainfall.
Further challenges persist with drain interception, where physical tapping of numerous drains remains incomplete despite feasibility studies. Construction is ongoing at some drains, while others are overwhelmed by rainfall, preventing verification of tapping efforts. Geo-tagging of key locations has been confirmed, but the proposed sewage treatment plant for Khoda-Makanpur is stalled, leading to untreated sewage discharge into Delhi and Noida drains.
Water quality monitoring of the Noida drain indicates the highest pollutant concentrations near the Delhi border, with levels decreasing towards the Yamuna River. Previous efforts by the Noida authority to increase treated-sewage reuse are noted, but the latest findings highlight the current on-ground status and the persistent environmental concerns surrounding sewage management in the region.
