Karnataka Minister Criticizes Municipal Authorities Over KC Valley Water Project
In Bengaluru, Revenue Minister Krishna Byre Gowda has issued a stern warning to municipal authorities for allowing untreated sewage to flow into lakes, a move he says is jeopardizing the ambitious KC Valley project. This comes amid growing criticism over the quality of treated water supplied to Kolar and Chikkaballapur districts and recent protests by farmers demanding tertiary treated water.
Scientific Backing for Water Quality
At a review meeting with experts from the Indian Institute of Science (IISc) and other ministers, Gowda cited long-term scientific assessments to counter allegations about water quality. "It is not just one or two years. Over the past six years, IISc has been consistently monitoring water quality, and tests have revealed no such concerns. Neither in surface water nor groundwater samples has any metal residue been found," he stated emphatically.
He highlighted the project's benefits, noting that groundwater levels have improved significantly, from depths of 1,800 feet to about 50–100 feet now. The water undergoes a five-stage purification process, with no harmful metal content detected, and there have been no reported health issues among people or livestock using the water.
Critical Flaw: Untreated Sewage Discharge
However, Gowda pointed to a critical flaw in the system: the unchecked discharge of untreated sewage by local urban bodies. "Such negligence by local officials is not only polluting water bodies but also damaging the credibility of the project. The mistakes of municipal authorities are tarnishing the very purpose of the KC Valley initiative," he cautioned, warning that years of positive outcomes could be undermined by poor governance.
Specifically addressing the situation in Chikkaballapur, he said, "Good quality water is being polluted by the discharge of untreated sewage from urban pockets. The sewage of Chikkaballapur town is directly let into these water bodies." He called for legal action against responsible officials and directed authorities to collaborate with BWSSB engineers to develop a plan for treating sewage before its release into lakes.
Positive Environmental and Agricultural Impacts
Reiterating the project's successes, Gowda shared that soil quality has improved, leading to successful cultivation of crops such as fenugreek, cucumber, beetroot, tomatoes, and flowers. Milk production has also increased due to better water and fodder availability. IISc experts conducted multiple field surveys, visiting residents three times to assess any adverse impacts, but no problems were reported; instead, people spoke of the benefits.
Environmental indicators are encouraging, with increased bird populations and healthy aquatic ecosystems. IISc has dismissed claims of rising nitrogen levels, further supporting the project's safety.
Future Monitoring and Sustainability Measures
To ensure continued safety and sustainability, Gowda suggested extending IISc's monitoring for another five to 10 years. He also instructed district officials to conduct biannual checks on fish health and meat quality. This proactive approach aims to maintain the project's integrity and address any future concerns promptly.
The KC Valley project, designed to supply treated water to arid regions, faces challenges from municipal lapses, but with scientific backing and proposed corrective measures, officials hope to restore public trust and enhance its long-term viability.
