Industrial Use of Treated Municipal Wastewater

[Ashish Bhardwaj]

Dear Members,

We all know that India is likely to become a water scare country in near future and there will be rise in conflict between the three segments of the society (i.e. Agriculture, Industry and Urban) on the usage of freshwater.

Industries have become conscious of the limited availability of freshwater and are taking measures to reduce their water footprint by employing various measures like reducing freshwater consumption, rainwater harvesting and searching an alternate source of water such as desilantion, waste water recycling, water reclamation etc.

Recently industrial use of treated Municipal waste water has gained momentum. I am aware that Bangalore Water Supply and Sewerage Board (BWSSB) and Chennai Metropolitan Water Supply and Sewerage Board (CMWSSB) are selling a certain quality of treated municipal waste water to industries.

I would like to know who are industries which are using treated municipal waste water as their process water after necessary treatment. I am aware of the some like ITC Limited, Madras Fertilizers Limited, Rashtriya Chemicals & Fertilizers Ltd. but there are other industries also.

I would request if anyone could give me the information, I would be grateful.

Thank you,

Warm Regards,

Ashish Bhardwaj

Dear Ashish,

I think you made a mistake in cost of purchasing treated wastewater. It is per cubic meter and not per liter. We are helping many Industries to recycle their sewage through bio-remediation techniques. Among them are P&G, Chenai, The Lawrence School Sanawar, Near Shimla, Ajit Bhawan hotel in Jodhpur. But I guess you are looking for purchasing organizations and not the ones who are recycling!!

Regards,

Sanjay

Alternately, the treated sewage can be used for construction activities in case of big township projects if those are being developed in phased manner or supplied to other construction projects by tankers.This can help utilize the treated sewage in the vicinity if there are no water intensive industries around.The cost comparison of treated waste water and fresh water however will be required to prove its affordability by the project proponents.

Thank you Mr. Sanjay and Mr. Indresh for correcting me. The cost is in KL only. It was by mistake I mentioned litre. Thank you all for your inputs!
