MPCB proposes tougher sewage treatment norms
PUNE: Stringent and uniform standards for sewage treatment in residential buildings and industries with more than 20,000 sq m built-up area is in the offing.
The Maharashtra Pollution Control Board has proposed that all sewage treatment plants should meet inland freshwater discharge standards to promote recycling and reusing of treated waste. The pollution control board has invited suggestions for and objections to the proposal.
MPCB officials said all residential buildings and industries with over 20,000 sq m built-up area must have a sewage treatment plant (STP). In industries, reuse and recycling of water is being promoted. For residential buildings, according to revised environmental consent norms, nearly 80% of the treated waste should be recycled.
If discharged treated water is being reused and recycled in residential projects, the officials said, wherever standards are met, such water is recycled. There is also much acceptance from the residents about reuse of treated sewage water. Such water is used for flushing, and gardening. In some areas, the treated water is released in drainage lines. Recycling of water depends on local constraints and conditions, the officials added.
The pollution control board said in the earlier treated sewage discharge standards, it was assumed that sewage after treatment will be used for agriculture. Environment clearance was granted with standards equivalent to irrigation norms. In all such environmental clearances, it has been mandatory that treated water is reused and recycled.
The pollution control board, officials said, has been given powers to prescribe more stringent standards than those specified by the union ministry of environment and forests. MPCB officials said with newer technologies for STPs, levels of treated water have improved.
