Outfall Sewer at Tarapur

Maintaining an ecological balance

Tarapur houses major industrial estates of Maharashtra including bulk drug manufacturing units, specialty chemical manufacturing units, steel plants and some textile plants. The highly polluting textile industries dominate this area. An outfall sewer was envisaged to carry effluent water deeper into the Arabian Sea to reduce the impact on the surrounding areas, marine life and maintain ecological balance.

SMC was entrusted with the work of laying the outfall sewer pipeline. It is placed below the sea bed at a minimum depth of 12m (the lowest water level at any time) and runs along the length of 7.1kms into the sea, thus mixing the effluent water with the sea water and diluting the impact.
