PMRDA and PCMC have planned projects worth over Rs 625 crore to curb pollution in the Mula, Mutha and Pavana rivers, which have seen repeated mass fish deaths and growing sewage contamination. In affidavits filed before the NGT last week, PMRDA outlined a Rs 500 crore project covering 107 km of the Mula, Mutha and Mula-Mutha rivers. It includes intercepting and diverting sewage from open drains and nullahs, decentralised and centralised STPs, interceptor sewer networks and ecological restoration. The target for completing execution is August 2030. Appointment of a project management consultant has begun, with four bidders in technical evaluation. The consultant will prepare the DPR, conduct surveys and finalise designs before execution tenders are floated.
PCMC has submitted details of a new 50 MLD STP at Wakad to cut the sewage load entering the Mula basin, funded from its own resources, with land acquisition being pursued after the draft DP approval. For the Pavana, PCMC listed sewerage works worth Rs 125.60 crore under its drainage master plan. Works worth about Rs 27.05 crore are in progress and Rs 98.55 crore are at tender stage, including about Rs 78 crore for strengthening the sewage network across zones. The Mula stretch in PCMC limits, around Pimple Nilakh, Wakad and downstream of Hinjawadi, has seen repeated pollution issues. In September 2024, dead fish near Pimple Nilakh made the NGT take suo motu cognisance. The targets are on paper, and the results will show in the water.
