Sewage and Effluent Treatment

Are Sewage Treatment Plants (STP) legally mandated in Apartments in Bangalore?

I live in an apartment in Bangalore which apparently does not have an STP. Currently the sewage is being redirected to a lake nearby. While a few of us would like to rectify this and construct an STP, the general consensus is to build one only if required i.e if the law mandates it.

Can someone clarify on what the Bruhat Bangalore Mahanagara Paike (BBMP) as well as Pollution Control Board norms say about this?

Oil and Grease Traps - Feasible Long Term Solutions?

Dear Friends,

Disposing of organic (Kitchen) waste eg. Fat, Oil and Grease from the Grease Trap is the major problem with Hotels and corporate Buildings. Grease Traps and STP's are mandatory by Pollution control board.

Fat, Oil and Grease (FOG) is Long Chain Fatty Acid which is difficult to degrade and condition in Grease Traps is adverse for natural bacteria to survive. That is why it is regularly scraped from the Grease traps.

Presently it is manual scraped which is unhygienic and disposing off at some distance places is also not environment -  friendly because it is non - biodegradable. Again Oil from the Traps flows in to STP's and it imbalances the bacterial activity of the STP that leads to STP's problems.

Discussion/Participation on this will be informative for every body and are people interested to know about bio solution for this critical issue? Do write in with your valuable suggestions 

Thanking You,

Sale of STP Treated Water : Legality?

Hello Everyone,

When we set up a Sewage Treatment Plant ,the treated water we get is mostly drained since mostly the requirement for recycled water is limited to horticulture,HVAC and flushing(provided the establishment has dual piping).My question is if I maintained all the parameters in STP Treated Water as per govt norms Is it legal to sell that water outside of that establishment to other organizations which require water for horticulture or for HVACs?

Is there any law against selling that water in India??

thanks & regards,

Tarun Joshi,
