Environmental Regulations for establishing a new water treatment plant

[Vidhu Tripathi]

Dear Members

I want to know weather EIA is required for establishing a large (say 80 MGD capacity with land area of 9.3 ha ) water treatment plant or not.

 

If EIA is not required what are the other Environmental Regulations need to be consider starting the construction.

 

Kindly give the quick reply

 

 

Regards

Yes, the project requires environmental clearance as the built-up area is above the 20,000sq.m limit and the state pollution control board is to be approached to start with. Otherwise also for funding agencies like World Bank, such projects require conducting environmental assessment to identify mitigation measures with responsibility and time frame.

2. Since the withdrawal is huge, permissions would be required from governing agencies like water utilisation committee under public works department.

3. Any other permission by virtue of the site ownership has to be dealt with.

4. EIA has to cover a lot of aspects like river quality, impact on nearby features, downstream users, discharge of wastes etc and site specific requirements if any.

The water treatment plant will be run by government agency for the purpose of water supply.

Any way has it got any relevance with Environmental Clearance.

projects are categorised based on the activity or proposal and not differentiated based on the proponent.

Sir,

Environmental Clearance is not required as long as no waste water is generated and it has no relevance wether it is run by government agency or government itself.

Dear Mr Tripathi,

1. Water treatment plant generates waste water. What happens to the suspended solids and bacteria attached to them? What is backwash water? Where does backwash water go?

2. Water found in nature is a natural resource. The ecological processes down stream are controlled by river flow. Any abstraction of major type would impact river ecology. This impact shall be mitigated. So is discharge of wash water laden with concentrated suspended solids and residual treatment chemicals usually running to tons per day. Consider the lowest flow period and predict the impact and suggest mitigation measures.

3. Water supplied from the treatment plant becomes waste water in the form of sewage and sullage. What are the management measures planned to cope with this waste water.

One thing is evident: any activity related to large water treatment plant needs EIA.
