For a planned town like New Town, it may be possible to scale up both activities to the city level.
The entire New Town has a network of box drains for draining off rain water from roads. These converge ultimately to a canal (like the link canal or pass-khal in Action Area 1, for example) and a Drainage Pumping Station (DPS) pumps out the water to the Bagjola Canal of Irrigation Department that ultimately takes it to the sea. The possibility I'm asking my engineers and planners to explore is as follows: can the DPS send the water to the nearby Tarulia raw water reservoirs where water from the 6ft pipes from Hoogly river will be brought in? In that case, we will save ourselves the cost and energy needed to pump in water from a 11 km distant source. We will also be able to supply additional water into the distribution channels.
For waste water too, there are Sewage Treatment Pumps (STPs) all over various locations of New Town. After treatment, the waste water is pumped out to bheries or canals. There is the possibility of using the treated water, with a second stage purification, to use for gardening (think of water needs of plants of Eco Park/ tea garden/ chilren's parks, greenery on medians) or in community toilets (think of Pay & Use toilets at Eco Park / Rabindra Tirtha/ Convention Centre etc) for flushing and washing.
I have advised Mr Debashis Banerjee, EE PHED to make out a basic concept note / discussion paper within the month. Thereafter we can have a technical discussion involving engineers, planners and experts.
