Sewage Treatment Plants in Majiwada, Thane.

In Majiwada an STP usually has to fit into a basement under the tower, because there is no ground left for it. Mixed-use buildings add a second difficulty: office floors send sewage through the working day, flats in the early morning and late evening, and the plant must handle both peaks. We size the equalisation to the building's own pattern, design ventilation so the basement does not smell, and plan how treated water returns to the building: flushing, cooling towers, landscape.

Majiwada sits at the junction where the Eastern Express Highway meets the start of Ghodbunder Road, with flyovers and the Metro Line 4 viaduct overhead. The old village of Majiwada survives in lanes of low houses, now enclosed by towers of twenty floors and more. Around it are commercial blocks, hotels and offices, much of it built on land that was once industrial or open. Traffic between Mumbai, Ghodbunder Road and the highways north passes through the junction day and night. The neighbourhood is largely built out: the change now is redevelopment and densification rather than new ground.
