Prism Johnson Limited has launched rental and leasing schemes for Effluent treatment plant / Sewage Treatment Plants for the Indian market considering the capex restrictions and enforcement of new waste water treatment standards.

We will provide a novel technology which has very low operational cost, lower footprint area thus saving costly real estate and long life of up to 15 years. The plant is modular in nature and capacity can be enhanced further depending on occupancy levels.


Customers pay less operation charges as the plant runs to only the occupation capacity at any point of time

Completely automated, reducing dependency on operators and the associated problems.

Highest level of treatment achieved complying NGT standards


Housing Society / Residential Associations

Pay less for the electricity charge during low occupancy period

Fully functional plant at full capacity inherited from the builder

Treated water complies with all standards stipulated by the Pollution Control Board and can meet even future stringent norms

Provision to recycle treated water for flushing, gardening, car washing etc.


Builder can pay the monthly rent or in form of 3 year EMI.

Reduction in high running cost during the initial occupancy period (first 3 years).

Plant has operating life of upto 15 years creating good will in market.

Less footprint leading to opening up of costly real estate for other purposes.
