As part of the Green City Mission, we are planning to recycle and re-use waste water. Sewage water, the black water that originates from domestic toilets and other liquid waste sources is typically treated in small septic tanks / soak-pits in rural/ semi-urban areas and is treated in sewage treatment plants in cities like New Town/ Salt Lake etc. The conventional STP (Sewage Treatment Plant) technology however has two disadvantages (a) it takes up a large amount of area and (2) its level of purification (30 BOD) is just fit for release into the environment (ie canals and rivers) but unfit for any use.
We were looking for modular space saving recyclable technology for the yet-unbuilt STP for Action Area 3 of New Town. Yesterday, even during the Viswakarma day, we had a detailed discussion with PHE and Hidco Engineers. We decided to opt for a smart solution. We decided to go for SBR (Sequential Batch Reactor) technology that will consume less land area (up to 50% less) and produce clean water (5 BOD). We will use the water to supply to Eco Park, children's gardens (there are eight in New Town), avenue plantations and road cleaning. The land area saved will be used to set up a modern solid waste processing plant.
