Common Effluent Treatment Plants is the concept of treating effluents by means of a collective effort mainly for a cluster of small scale industrial units.
This concept is similar to the concept of Municipal Corporation treating sewage of all the individual houses. The main objective of CETP is to reduce the treatment cost for individual units while protecting the environment.
Especially designed for industrial estates and SEZs, where establishment of individual effluent treatment facility is not possible; concept of Common Effluent Treatment Plant (CETP) comes into effect.
It is a kind of waste management, where small and medium sized industries jointly treat their wastewater affordably by installing such an Effluent Treatment Plant, which is common for every unit.
Installation of ETP for single manufacturing unit is not possible due to budget problem and limited area allotment to each unit; therefore, a CETP is a best option which not only protects water environment but also divides the investment and operational costs. Wastewater pipelines from every manufacturing unit are connected to the CETP for treatment.
