Decentralized sewerage system is defined as the collection, treatment, disposal/reuse of sewage from individual homes, clusters of homes, isolated communities or institutional facilities, as well as from portions of existing communities at or near the point of waste generation.
Advantages of Decentralized Sewerage
1.In general, prediction of sewage volumes is far easier in decentralized sewerage micro collection areas and to that extent the design becomes realistic.
2.Flows in a decentralized sewerage are relatively smaller than conventional sewerage and this implies that environmental damages from any mishaps are also minimal.
3.Given the smaller flows, the sewer sizes are also smaller and the depths of cut are also less thus, making it easy to construct and maintain.
4.Additions of new service areas which are independent of the existing system and the need to augment or enlarge the existing sewers and STPs are avoided.
5.The STPs are smaller and it is easier to find the reuse prospects nearby as compared to all the sewage being treated in one far corner.
6.It is also easier to layout return lines of treated sewage for use in medians, industrial supplies, flushing far flung head manholes, etc.
7.The ecology of rivers, streams and receiving waters are better managed
