Tata Innoverse is seeking solutions in the form of smaller size and modular PSTPs so that they can be moved on narrow roads and installed in the available space. The area and road width (to move PSTP) constraints are as below.
Small towns in India struggle with the problem of collecting and treating sewerage. Septic tanks have been in use for such locations and tanks would be cleaned as per need. However, rising human encroachment has reduced the space on roads which inhibits reaching these septic tanks for cleaning and maintenance purposes. This leads to problems with overflow in these septic tanks causing inconvenience (bad smell, hygiene issues, etc.) to the residents.
Packaged sewage treatment plants (PSTPs) of varying capacities (as depicted in Figures 1 and 2) were deployed to collect and treat the sewage in-situ, without the need for collection (from septic tanks) and transfer to a centralized treatment unit. The required space and approach roads became a problem that limits the use of PSTPs.
