NEW DELHI
The Kejriwal Government will develop decentralised STPs in the parks of the national capital. The key objective of the decentralised STPs is to ease the colonies from the burden of rising water pollution, foul smells, and declining underground water tables in most of the colonies of Delhi. Water Minister and Delhi Jal Board Chairman Shri Satyendar Jain took stock of the construction work of the Decentralised STP and instructed officials to beautify the park and improve the landscape as well. He stated, “This initiative of the Kejriwal government will eliminate the problem of irrigation in Delhi’s parks. Decentralised STPs ought to emerge as “sustainable” alternatives to large STPs that require costly supply, effort, and delivery of infrastructure.” Notably, the Delhi Government is developing five model Decentralised-STPs at Sheikh Sarai, Rose Garden, Prahladpur, Model Town and Sandesh Vihar
Water Minister Shri Satyendar Jain, took stock of the ongoing construction work of the Decentralised Sewage Treatment Plant (D-STP) at Sandesh Vihar, Pitampura on Monday and instructed the officials to make optimal use of the space provided for the public park and improve the landscape and aesthetics of the public garden. He said, “Decentralised STPs will solve the problem of sewer overflow in the city. Apart from this, recycled water will be used for horticulture, which will help us shut all the tubewells and ultimately save precious groundwater. Public facilities shouldn’t be compromised, rather be improved now that we can. With the increasing population and the demand to provide better facilities with existing land area, this new innovative treatment solution is the need of the hour. It’s not only cost-effective but also sustainable and environmentally friendly. Decentralised STPs will save a significant amount of groundwater in Delhi, which may then be utilised for human use during the hot summer months. The treated water contains a high concentration of nutrients that will work as a powerful fertiliser for plants and trees, with no additional costs associated with fertiliser procurement.”
What is a Decentralised STP?
A Decentralised-Sewage Treatment Plant (D-STPs) is a mechanism where a small treatment plant is constructed that treats wastewater at the site of origin. It’s a flexible, sustainable alternative to large treatment plants that require miles of costly supply and delivery infrastructure. Currently, Sewage Treatment Plants (STPs) are installed at a distant geographical location in the city and water is collected from different sources and treated for further use by laying an expensive conveyance system. This new innovative system will not only resolve the complex issue of sewage transportation but will also help rejuvenate the local water bodies and increase groundwater through groundwater recharge.

Importance of Decentralised STPs in Delhi
The implementation of the Decentralised STPs will save a huge quantity of groundwater in Delhi which could be used for human consumption during tough times of peak summers. The treated water has a high content of nutrients which will act as a strong fertiliser for plants and trees and no additional cost will be incurred on the procurement of the fertilisers. The recycled water can be used for horticultural and gardening purposes in the respective parks. Presently, the treated water from far off treatment plants is being transported to the different public parks of the city which comes at a high cost. On the other hand, many parks in Delhi use tubewells to extract groundwater to meet their horticulture and gardening needs. The extracted underground water is of drinking water quality which is a precious resource. To save this scarce resource and shed the load from potable water sources, these D-STPs in the parks inside the colonies will supply recycled water for horticulture and gardening purposes.
The Decentralised-STPs would lift extra wastewater during peak flow, carry out the necessary treatment, and then collect the recycled water in the collection tank built in-situ. The recycled water has a high content of nutrients and it will act as a strong fertiliser for plants and trees and no additional cost will be incurred on fertilisers.
The decentralised STPs will result in saving a huge quantity of water every day, which will allow the government to shut down all tube-wells and contribute to the health of underground aquifers. The treated water will also not require any additional pipeline for supply, therefore, it will be pocket friendly.
The D-STPs will help solve the twin challenges of sewage overflow and the arrangement of water for public parks and gardens, thereby saving precious underground water.
Five Model D-STPs Being Created
As a pilot project, the Delhi Government is developing five model Decentralised-STPs at these locations- Sheikh Sarai, Rose Garden, Prahladpur, Model Town and Sandesh Vihar.
How is a D-STP different from a traditional STP?
Decentralised-Sewage Treatment Plant (D-STPs) is a wastewater treatment system that captures the waste water of the area there itself and supplies the recycled water as per need.Currently, Sewage Treatment Plants(STPs) are installed at a distant geographical location of the city and water is collected from different sources and treated for further use by laying an expensive sewage pipeline system.
In STPs, pollutants including disease-causing bacterias are eliminated using treatment systems which also cleans the pollutants from households, commercial spaces and industries. Further, the laying of pipeline network to the parks is an expensive and cumbersome task whereas the decentralised STPs not only resolve the complex issue of sewage transportation but are also economical. The D-STPs also help rejuvenate local water bodies and increase groundwater levels by allowing the treated water to flow into them.
D-STPs, unlike STPs, do not require the acquisition of large pieces of land, man and machinery. They have the capacity to become carriers of localised hygiene, water supply and ecological restoration.
Decentralised STPs ought to emerge as “sustainable” alternatives to large STPs that require miles of costly supply, effort, and delivery of infrastructure.
