Sewage Treatment Plants in Naigaon, Vasai-Virar.

Naigaon's larger layouts rely on on-site sewage treatment, and shallow groundwater and flood risk affect how they should be built. Underground tanks need to resist uplift and keep floodwater out, and electrical equipment has to be raised clear of floodwater. Surface water entering through manholes can flush the biology out in one storm. We design and repair plants with these conditions in mind, seal them against inflow, and set up operation that keeps the treated water within limits through the monsoon.

Naigaon is the southern gateway to Vasai-Virar, the first station after the railway crosses the Vasai creek from Bhayandar. Much of its land is low and flat, and until recently a great deal of it was salt pans, paddy and marsh along the creek, with mangroves fringing the water. Over the last two decades large residential layouts have grown up on this land, especially on the eastern side, alongside older villages and some industrial and warehouse sheds. The creek, the tides and the monsoon still shape the ground here more than anywhere else in the town.
