As per field surveys and observations in Mysuru, 7% of the total population is dependent upon OSS out of which 1% of the total population of Mysuru has septic tanks in their respective households with outlet connected to open drain or storm sewer, 3% of the total population has lined pits with semi permeable walls and open bottom without any outlet or overflow and 3% has unlined pits with no outlet or overflow. Emptying frequency differs widely across the city, depending upon the type of OSS and the size of household. Faecal sludge is discharged by private emptiers into open drains or other water bodies, since no co-treatment is practised and there are no dedicated faecal sludge treatment plants. There is no treatment of the FS collected since it is discharged directly into the drains, reaching the environment, untreated.
