Burtuk and Chandmari, two wards in Sikkim, India, had no public water supply,
leaving the population dependent on unsafe, untreated spring water. The $4.45
million project to design and construct a water distribution system and service
reservoirs included chlorinators at the reservoir locations and bulk flow meters
on pumping and distribution mains.
The hilly terrain, high elevations, and fixed boundary conditions were major
challenges to designing a system that achieves maximum residual pressure.
Using WaterGEMS, Microsoft Excel, and AutoCAD reduced the time model
builders needed for network drawings and helped them design a system with
residual pressures within the boundary limits.
Zhengzhou Water Supply Corporation
The Water Supply System Modeling of Zhengzhou
Serving a population of 3.4 million in northern China, Zhengzhou Water
Supply Corporation decided to convert to digital management of the water
supply network. Technicians built a hydraulic simulation model of the water
supply network, which included the collection of basic data, import of GIS data,
improvement of topological structures, and water allocations. Capital cost
WaterGEMS enabled the company to create a beneficial hydraulic simulation
model. The model helps keep the error value within 1.6 meters between the
model’s simulated pressure outcome and measured value, and its flow error
under 10 percent. The model and its application aid pipeline management and
optimize dispatching crews for outages.
