Waste Management
India’s Current Sewage Treatment Situation
TL;DR: India’s sewage treatment still has big gaps. A 2015 CPCB census found only about 522 of 816 STPs fully operational, and even these fall short of capacity. About 60% of the urban population relies on onsite treatment systems. New norms, such as Mumbai’s rule that large housing projects treat waste in house, bring land and knowledge challenges that biological technology can help solve while lowering OPEX and CAPEX.
For a country like India, which is looking to revolutionise its sewage wastewater management systems, the gaps in the functionality of current treatment systems are very high.
The CPCB’s 2015 census report states that out of India’s 816 STPs, only about 522 are fully operational and do not meet their entire capacity of treating sewage.
While the coverage of sewage treatment and toilet facilities has greatly risen under the 2014 Swachh Bharat Mission, about 60% of the urban population depends on On-site treatment systems, and the remaining 40% are serviced by sewerage systems.
In metro cities like Mumbai, housing projects with more than 20,000 sq metres are given clearance upon the condition that they treat solid waste in-house, making it mandatory for them to have functional and compliant private STPs.
With the introduction of new norms come problems associated with land availability and the overall lack of the right knowledge and software to efficiently treat the sewage while managing costs and abiding by discharge norms.
To address current sewage challenges faced in residential STPs, hospitals, malls, hotels, educational institutes, and municipal STPs, Organica Biotech adopts solutions by leveraging biological technology to lower overall OPEX and CAPEX costs.
