Municipal sewerage comprises Industrial and domestic effluents, which leads to water/land pollution. The contamination level depends on the status of the effluents, the characteristics of contaminants, installed processing techniques, and the economics of treatment. In India, approximately 22,900 million litres per day (MLd) of domestic sewages are generated only from the cities and towns. Amongst these, only 5,900 MLd can be treated as per the installed treatment capacity [1, 2]. This concludes that the country is equipped with only 25.8 per cent of domestic sewage treatment facilities. Thus, almost 17,000 MLd of effluents, which is almost 6 billion m3 per year, are being discharged to natural sources without treatment [1, 2]. A few hundred billion m3 of natural water is being contaminated by discharging these effluents to the natural sources. India has established effluent water quality standards, considering the importance of the water bodies in which the effluents are being disposed of. The monitoring and regular testing facilities of the effluents prior to their disposal are costly and thus often neglected. However, it is important that municipal sewerage should be reused to cater for the water demand and risk of contamination of natural water sources. It is a common belief that sewerage water treatment is costly, and thus, many municipalities are reluctant to establish sewerage treatment plants (STP). The municipal corporations are willing to set STP through outsourcing. However, the small scale business setups, which are willing to engage themselves for water treatment job as an outsource company, are facing difficulties of cost analysis prior to quote. Often, these companies do not find any guidance for the same and come out with a wrong quoted value. This paper highlights the outcomes of an analysis carried out on municipal sewerage quality and the estimation of possible costs for its analysis and treatment. However, this cost analysis does not include solid (sludge) handling/disposal/reuse costing. This may guide the small scale business group to arrive at the possible pricing for STP set up.
