Case Study: DTK Hydronet Solutions achieves 100% 24/7 water supply for 600 Bankura villages with Bentley WaterGEMS

Rural Villages in Bankura to Receive 100% Water Supply with New Bulk Water Supply Scheme

DTK Hydronet Solutions was retained by the Public Health and Environmental Engineering Department of West Bengal and the Asian Development Bank to design a new bulk water supply for four blocks in Bankura, serving 600 villages and nearly 1 million residents. The customer faced severe drought, arsenic- and fluoride-contaminated groundwater, an antiquated leaking asbestos-cement network that delivered only ~20 L/person/day for less than 45 minutes, and high waterborne disease mortality—so they needed a 24/7, equitable system delivering ~70 L/person/day to every household. Bentley’s WaterGEMS and HAMMER were used as the core modeling and analysis tools.

Using Bentley software, DTK Hydronet built a single GIS-integrated hydraulic model (leveraging WaterGEMS modules like Model Builder, TRex, LoadBuilder, Darwin Designer and CONNECT Advisor, and HAMMER for transients) to test 30+ transmission and 90+ distribution scenarios, optimize pipe diameters, pumps, PRVs and DMAs, and produce construction-ready iModels and maps. Bentley’s tools cut design time by 80% and design costs by 40%, reduced total project capital by about 16% (saving ~INR 2 billion), sped delivery by nine months, and enabled a design that delivers continuous, arsenic- and fluoride-free water to 100% of the target population—improving service for roughly 1 million villagers.
