Polluted drains carrying industrial waste to rivers: PCMC report
The ESR 2024-2025 states that 60 nullahs flow into the Pawana River, 12 into the Indrayani River, and nine into the Mula River. These nullahs are natural channels meant only for rainwater. However, during inspection, these were found carrying a dangerous mix of household waste, sewage, and industrial effluents, especially from slum and industrial areas. This untreated wastewater enters rivers, severely degrading the water quality.
According to civic officials, during the seasonal chemical testing in the Pavana, Mula and Indrayani rivers, Pavana was identified as the most polluted. Since it flows through the heart of the city, it receives direct inflow from several contaminated drains. Indrayani, which flows through industrial belts, is the second most polluted.
As per the report, the pH (potential of Hydrogen) levels of all three rivers are within the permissible limits set by the Maharashtra Pollution Control Board.
However, environmental experts are of the view that even within acceptable pH levels, other harmful chemicals can become more soluble at lower pH values, posing serious risks to aquatic life.
Green activist Prashant Raul said, 'Many references and data are unrealistic and misleading, or may have been copied and pasted from a previous report, or are based on wrong information. I will raise objections against this ESR. The nullahs and rivers were polluted even in the previous years, but no measures were taken by PCMC.'
However, Sanjay Kulkarni, city engineer and head of the environment department at PCMC, said action has been initiated against individuals and industries found releasing untreated wastewater in nullahs and rivers. He also said that the civic body has prepared a master plan to combat water pollution.
'We will set up several STPs (sewage treatment plants) which will be able to treat over 300 MLD of wastewater. The PCMC has sent the proposal to both the central and state governments, seeking funds under various schemes,' he added.

PCMC's green claims fall flat as ESR reveals air, river pollution still high
1 2 3 4 Pune: The latest Environment Status Report (ESR) of Pimpri Chinchwad Municipal Corporation (PCMC) reveals alarming levels of air and river pollution across the twin cities, despite the civic body's claims of launching green initiatives. The revelation has drawn sharp criticism from environmentalists and residents alike. The ESR data for 2024-25 reveals that the city's average particulate matter (PM) 2.5 and PM10 levels — key indicators of air pollution — significantly exceeded India's National Ambient Air Quality Standards.

Prashant Raul, an activist from the Green Army group, slammed PCMC's initiatives and said, "The ground reality is far worse than even what the ESR suggests. If our rivers remain polluted despite crores of rupees spent on green projects, something is seriously wrong with PCMC's approach. Their awards for environmental initiatives now seem hollow in light of this report." In June 2025, PCMC raised Rs200 crore via green municipal bonds to fund sustainable projects like Harit Setu. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Cliff Richard's Partner Finally Revealed – You Won't Believe Who Outlier Model Undo Last year, it also clinched top spot in the state's 'Majhi Vasundhara Abhiyan 4.0' for environmental conservation. Raul told TOI that the ESR's detailed findings show dangerously low DO levels in parts of the Pavana river. "Low DO levels threaten aquatic life and pose serious health risks to residents relying on these rivers," he said. Last year, the Central Pollution Control Board (CPCB) classified the Pavana river under the 'Priority 1' category, marking it among India's most polluted rivers. Despite its role as a primary drinking water source for the city, PCMC's efforts to address river pollution appear inadequate. Reports of floating dead fish and toxic foam in the river are frequent. Activists blame the civic body for releasing untreated effluents into rivers due to an inadequate network of sewage treatment plants (STP). Shailaja Deshpande of NGO Jeevitnadi, who has been working in the river conservation sector for several years, highlighted, "The STPs within PCMC limits are not operating in accordance with CPCB norms, resulting in a significant amount of untreated effluent being released directly into the rivers." When it comes to air pollution, local resident Pushkar Kulkarni attributed the surge to unplanned development. "New high-rise projects are mushrooming, but there is no proper planning for resources. Construction dust is a major contributor to PM2.5 and PM10 levels, and norms are not strictly followed," he said. Despite being a major industrial hub, Pimpri Chinchwad lacks a dedicated facility for hazardous waste disposal as well. "Without proper disposal systems, illegal burning of hazardous waste is rampant, further worsening air quality," pointed out Raul. Sanjay Kulkarni, PCMC's city engineer and head of the environment department, acknowledged the rising pollution levels but attributed them to ongoing construction and development activities. "We have introduced measures like mechanical road sweeping, fog cannons, and air bins under the National Clean Air Programme. A dedicated squad also monitors compliance at construction sites," he told TOI. On river pollution, Kulkarni said, "We have prepared a master drainage plan to prevent untreated discharges into rivers, but we are awaiting funds from state or Central govts. In the past six months, PCMC added three new STPs, with one more set to be operational soon. At present, 20 STPs are functional across the city, and we are committed to cleaning our rivers."

Polluted drains carrying industrial waste to rivers: PCMC report
Almost all nullahs in the Pimpri Chinchwad area which flow into rivers are highly polluted, according to the latest Environmental Status Report (ESR) released by the Pimpri Chinchwad Municipal Corporation (PCMC) on Tuesday. These drains continue to discharge water even during the summer season, indicating a constant flow of domestic sewage and chemical-laced wastewater, causing significant pollution in the rivers. These nullahs are natural channels meant only for rainwater. However, during inspection, these were found carrying a dangerous mix of household waste, sewage, and industrial effluents, especially from slum and industrial areas. This untreated wastewater enters rivers, severely degrading the water quality.

PCMC releases Environmental Status Report 2024-25, civic chief says valuable guide for road ahead
The Pimpri Chinchwad Municipal Corporation (PCMC) on Tuesday unveiled its Environmental Status Report (ESR) for 2024-25, which officials said offered a comprehensive review of the city's environmental indicators and progress. The report was released by Municipal Commissioner Shekhar Singh during the Standing Committee meeting on Tuesday. 'The environmental progress Pimpri Chinchwad has made is not just the achievement of our systems, but a reflection of the collective participation of our citizens. This ESR is a mirror of our journey so far and a valuable guide for the road ahead,' the civic chief said after releasing the report. 'This report is more than just data—it's a roadmap for Pimpri Chinchwad's sustainable and resilient future. With community participation and administrative commitment, our city can become a national benchmark in green urban living,' said Vijaykumar Khorate, additional commissioner, PCMC. The report takes a comparative look at environmental trends over the last three years and presents detailed insights into the city's land use, population dynamics, rainfall data, water supply, sanitation, air and noise pollution, soil quality, solid waste management, energy usage, transport systems, and key public services. It also covers the impact of smart city initiatives and urban renewal projects, officials said. A key highlight of the report is that Pimpri Chinchwad has once again secured the 'Water+' certification for fulfilling all sewage treatment and reuse benchmarks. This marks the second consecutive year that the city has achieved this status. In addition, PCMC has successfully retained its 7-Star Garbage Free City rating under the Swachh Bharat Mission, thanks to its robust solid waste infrastructure that includes waste-to-energy plants, decentralised composting units, bio-medical and hotel waste processing systems, as well as construction and demolition (C&D) debris treatment facilities, the report said. In 2024-25, the city carried out extensive afforestation drives, planting a total of 1,73,576 native trees with the active involvement of civic bodies, NGOs, schools, and citizens. Air quality monitoring data showed that PM10 and PM2.5 levels exceeded permissible standards during certain months, with AQI readings in the 'good' category during monsoon, 'satisfactory' in summer, and 'moderate' during winter. Rising vehicular emissions remain a concern, with a 36% increase in registered vehicles over the past year. However, the share of e-vehicles has steadily increased to 3.5%, with over 50,902 electric vehicles now operating in the city, the report said. PCMC's commitment to sustainable public transport is evident in the growing PMPML fleet, which now includes 1,948 buses—of which 490 are electric and 225 run on CNG. On the sanitation front, all 19 sewage treatment plants in the city collectively process 332 MLD of wastewater, with 31 MLD reused each month for street washing, dust suppression, and landscaping, the report said. The city's waste-to-energy plant has processed over 3.5 lakh metric tonnes of household waste to generate more than 13.6 crore electricity units to date. The C&D waste plant has processed nearly 40,000 metric tonnes of debris, while the hotel wet waste project has produced 1.12 lakh kilograms of biogas from over 3,593 metric tonnes of organic waste. 'This year's ESR not only captures data but also documents the scientific and process-based efforts taken to protect and enhance our environment. Our goal has been continuous improvement, and we hope this report serves as a model for other cities,' said Sanjay Kulkarni, chief engineer, PCMC.
