See how Agra has improved its water network and prevented leakages


The Rs 34-billion Agra Water Supply Project delivers an adequate supply of treated water 24/7 to Agra. Undertaken by NJS Engineers for Uttar Pradesh Jal Nigam, the project includes construction of a 144 million-liter-per-day water treatment plant, sedimentation tank, and a 130-km transmission pipeline. Rehabilitation and repair of two water treatment plants, overhead tanks, clear water reservoirs and distribution networks were also undertaken.

The distribution network installation, leakage prevention, and rehabilitation were challenging due to high volume of non-revenue water. A GIS-based spatial database of assets was developed, and WaterGEMS was used to create a hydraulic model for existing, intermediate, and future water supply zones. Through this, the agency prepared the GIS-based asset database, project area database, and land acquisition database and to develop water network hydraulic models. These applications were essential in planning system rehabilitation, improvement, and expansion as well as establishing efficient operational strategies and reducing non-revenue water.

The model was used to evaluate network flow, capacity, and pressure; plan system rehabilitation, improvement, and expansion; monitor non-revenue water; and develop efficient operational strategies.

The project provided a robust system for identifying the most pronounced weaknesses in the network and ensured that these deficiencies will be addressed well in advance of issues arising that would impact the delivery of service to consumers. The functional water network eliminated the need for thousands of water tankers that would have been required to deliver water to affected areas each week had they not used Bentley’s solution.

The existing system delivered an intermittent water supply, with pumping stations operating a few hours a day. A pilot project repaired 206 of 308 leakages in six months, increasing the population served from 57 to 72 per cent. The hydraulic model developed using WaterGEMS will continue to be used as a tool in monitoring non-revenue water

The hydraulic model built with WaterGEMS provided a complete representation of the city of Agra’s water distribution system, including all of the pipelines, pump stations, tanks, and control valves. The model was used to determine which pipes to replace, how to setup control valves, and where to draw boundaries for pressure zones and district meter areas. Without the model, a manual approach to alternatives would have been random, untested, and inefficient.
