COMMON EFFLUENT TREATMENT PLANT

The concept of common effluent treatment plant has been accepted as a solution for collecting, conveying, treating, and disposing of the effluents from the industrial estates. The effluent includes industrial wastewaters and domestic sewage generated from the estate.

​

A CETP can be changed to combined effluent treatment plant when it collects sewage from surrounding localities and treat it with industrial wastewaters.

 

CETP is designed on the basis of:

​

• Quality and flow rate of the wastewater.

• Effluent standard required by CETP.

• Possibility of recycle and reuse of treated wastewater.

• Availability of land, manpower, energy and expertise in specific treatment methods.

• Willingness of the industries located in the industrial estate to contribute towards the capital and operating expenses of CETP.

​

Advantages of providing CETP

​

• Small and medium scale industries are not required to treat their wastewater separately.

• Assured wastewater treatment hence better control over pollution.

• Concerned pollution control agency has to monitor only one treatment plant for its performance.

• Participating industries have commitment to generate wastewaters acceptable to CETP.

• Industries are responsible for finding ways to minimize pollution load and reduce water consumption to the extent possible.
