The Pune Municipal Corporation's directive to use treated sewage water at construction sites has largely failed due to weak enforcement and logistical hurdles. Builders continue to deplete groundwater and use potable water tankers, exacerbating the city's water stress.
Technology and Compliance Issues
The PMC's smartphone application, the "PMC STP Tanker System," has over 700 registered developers and 138 tanker operators. However, its impact on the ground remains inconsistent. The technology has not ensured widespread compliance with the mandate.
Developers' Concerns
Developers argue that treated water is unsuitable for construction, potentially compromising structural integrity. One developer stated, "Potable water ensures better binding of cement and materials. Treated water might be fine for curing or cleaning, but using it in core construction could damage the structure." Cost is another issue, with treated water costing nearly double. Water from wells or borewells costs around Rs 800 to Rs 900 per tanker, while treated water can range from Rs 1,600 to Rs 2,000 per tanker due to transportation from distant sewage treatment plants.
Civic Activists' Criticism
Civic activists term the non-compliance a governance failure. Vivek Velankar of Sajag Nagrik Manch said, "There is a clear reluctance among PMC officials to crack down on violators. Senior officials who turn a blind eye must be held accountable. We have even seen potable water being used in public toilets, which is sheer mismanagement." Ameya Joshi of Kothrud questioned the PMC's inaction, noting that residents face water cuts while developers use water freely for commercial activities. "It is an injustice to ordinary citizens," he added.
PMC's Response
PMC officials claim awareness campaigns are underway and adoption is improving. Nandkishor Jagtap, head of the PMC water supply department, said, "We have created a dedicated mobile platform and are seeing increased engagement." The PMC itself uses treated water for gardening, road cleaning, and public infrastructure maintenance.
Scale of the Challenge
Nearly 150 tankers are used daily for private construction, with another 200 for civic projects, including road works, Metro construction, and the 24x7 water supply scheme. A PMC survey two years ago found that out of 326 active construction projects, only 118 complied with the treated water mandate, while 208 were issued notices for violations.
