Maharashtra Industrial Development Corporation (MIDC) has rolled out a major infra project of laying 106 km of pipelines to carry effluents and sewage in the 22-km long TTC area, after pressure for quick action from MPCB. The project has an approximate budget of Rs 200 crore.
The new high-density polyethylene pipelines will be laid alongside the old ones so that there is no disruption in the transportation of effluents to the Central effluent treatment plant (CETP). “This new variant is long-lasting and will not clog. The earlier cement pipeline passage would get clogged due to acidic effluent from several units, which have now shifted,” said MIDC sources.
The work will be carried out in phases with a deadline of 2018. The tender for laying new pipelines from pump stations at Sanpada and Rabale to CETP is under scrutiny. “The work will roll out in about a month’s time,” said an MIDC official. The pipeline also carries sewage.
MIDC has also approved a pipeline network of 25km for enhancing collection system and tender will be called shortly. It is also considering a 2-km pipeline from CETP to a nullah connecting to Vashi creek for final discharge of effluent.
Anil Mohekar, regional officer, MPCB had stated that there is an urgent need to replace the 25-year-old pipeline, as it had leakages in several places after which MIDC stepped up efforts to repair the leaks, as and when reported. The Thane Belapur Industry Association also expressed its concern on the frequent breakages.
