One-Stop Shop Sewage Treatment Plant in India
Jaipur plant converts sewage into treated water for farming and generates electricity from methane captured by the facility.
Farmer Lala Ram lives in the city of Jaipur in the northern state of Rajasthan in India. He remembers the time when sewage contaminated ground water in the city. Left with no alternative, farmers like Lala Ram used the untreated sewage water for growing crops and vegetables. The sewage also became a health hazard in Jaipur

Before the sewage used to flow just like that. It used to collect in the fields. It would give rise to mosquitoes. There was a fear of epidemic and disease.
In 1998, the government of Rajasthan established the Rajasthan Urban Infrastructure Development Project or RUIDP-1 as an entity under the Urban Development and Housing Department. The Asian Development Bank gave financial assistance to the endeavor, which provided investments in the water supply and sewage sectors across six major cities in Rajasthan.
As part of the project, RUIDP-1 built a state of the art sewage treatment plant in Jaipur. The facility treats and cleans nearly 62.5 million liters of sewage a day. The treated water is released into channels and farmers use it free of cost to irrigate their farm fields.

The water treatment plant has really helped the farmers. The sludge is using the fields and the treated water is used for irrigation purposes to grow vegetables. I can also grow wheat.
Methane captured from the plant is also used to generate clean electricity to run the entire facility. The Jaipur Municipality says this will save more than USD 300,000 a year in electricity cost.

It’s also generating power, which is used for running this plant. It helps generate government revenue by saving electricity cost.
The treatment plant is really a one-stop shop. It transforms sewage to water for farming, harnesses alternative energy, while saving valuable electricity.
