Decentralised/Sustainable Wastewater Treatment Technologies

The centralised sewage treatment technologies have proven to be expensive, complex and are failing to cater to the total wastewater generated. The untreated/partially treated wastewater makes its way to the water body causing immense degradation of the ecosystem and the environmental health.

Need is for sustainable wastewater treatment technologies - to locally treat the sewage and also reuse/recycle. The decentralised sewage treatment can be both electro-mechanical system that have higher energy requirement or natural systems with less or no energy requirement.

CSE has reviewed and documented select case studies that present innovative, sustainable and affordable ways treating the sewage locally including reuse/recycle. The case studies comprise of the wastewater treatment systems which have been implemented at individual, community/cluster and at municipal level. The case studies documented discuss the principle, salient features, and performance indicators and provide details of individuals or agencies/institutions who have implemented the system

The cost comparison of the natural technologies listed under decentralised sustainable wastewater management practices has been presented in the table here..
