Pune: PMC Introduces Real-Time Digital Monitoring for Private STPs in Housing Societies

The Pune Municipal Corporation (PMC) is taking significant steps to enhance urban pollution control and wastewater management. As part of this initiative, the PMC is preparing to introduce real-time digital monitoring of private sewage treatment plants (STPs) installed in housing societies across the city. This move aims to ensure that sewage is treated properly and prevent untreated water from entering drains and riverbeds.

Additional Municipal Commissioner Prithviraj B. P. emphasized that the proposed sensor system will enable the civic administration to verify whether STPs are operational and whether sewage is being adequately treated. The live data will be available at a central control room, providing continuous oversight and immediate alerts in case of any issues.

This initiative follows the PMC’s earlier decision to mandate air quality sensors at construction sites as part of its broader pollution control measures. Now, similar technological oversight is being extended to wastewater treatment, reflecting the growing concerns over untreated sewage entering the environment. According to the civic administration, more than 750 private STPs are currently operational in Pune. Development control rules require housing societies with more than 100 flats to install sewage treatment plants. However, the PMC has frequently received complaints that many of these STPs are either not operated regularly, poorly maintained, or fail to meet prescribed treatment standards.

To address these gaps, the PMC is exploring the installation of sensor systems that will monitor key parameters such as water flow, treatment status, and the quality of treated water. Once implemented, these private STPs will be digitally linked to the municipal monitoring mechanism, enabling continuous oversight and ensuring that the systems function effectively.

The initiative aligns with the city’s long-term water reuse and pollution reduction goals. Several large-scale sewage treatment projects are currently underway in Pune under the AMRUT scheme, with five major projects expected to become fully operational in the coming months. The proposed monitoring of private STPs is seen as a complementary step to ensure that decentralized wastewater treatment systems are functioning as intended.

The civic body acknowledged that enforcing compliance has been a challenge, given the scale of private STPs spread across the city. Untreated or partially treated sewage discharged into nullahs and rivers poses a significant risk of water pollution, making technological intervention necessary. The PMC is now working on finalizing the framework for sensor installation, including cost estimates and implementation timelines. As per the initial plan, housing societies will be required to bear the cost of installing the sensors on their STPs.

“The sensor system will provide real-time data on water flow, treatment processes, and output quality from STPs. This will make it easier to take action against societies violating norms and will also promote water reuse while helping curb pollution in rivers and streams,” Prithviraj B. P. explained.

Civic officials indicated that once the policy is finalized, detailed guidelines will be issued to housing societies, marking a significant shift towards technology-driven environmental regulation in the city. This move is expected to enhance the overall water quality and contribute to a cleaner, more sustainable urban environment in Pune.
