The INR 34 billion Agra Water Supply Project delivers an adequate supply of treated water 24/7 to the city of Agra, India. 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 130-kilometer 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 the high volume of nonrevenue 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. The model was used to evaluate network flow, capacity, and pressure; plan system rehabilitation, improvement, and expansion; monitor nonrevenue 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 solutions.
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.
