Project

A Need for Adequate Water Infrastructure
Situated on the banks of the Brahmaputra River, Dibrugarh is a major city in Assam, India, and an emerging industrial, educational, and health care center in the region. Despite its riverside location, the town has no centralized potable water supply facility for the 25,391 households, home to 167,733 people. Given the unreliable, inequitable water supply and highly compromised water quality, the government initiated a water infrastructure project to ensure adequate distribution and 24x7 access to clean drinking water. The USD 25 million initiative includes engineering, procurement, and construction of a 220-kilometer integrated water network. DTK Hydronet was hired as the engineering consultant and faced coordination and engineering challenges while working with the contractor and utility, as well as addressing non-revenue water (NRW) concerns.

Digitalizing Conventional Engineering Practices
Hydronet wanted to implement hydraulic modeling and analysis for the entire scheme and develop an integrated asset management platform, which would help them meet the utility’s demands and limit NRW. However, it was impossible for them to work with the utility’s conventional file sharing methods and conduct hydraulic studies within the stipulated time frames. Faced with a missing central data repository, no provision for district metered areas (DMAs), and insufficient, manual utility processes, DTK Hydronet needed to establish an open, connected data environment and digitalize engineering workflows and asset management. This system would help them optimize collaboration, design, and lifecycle operations.

Solution

Bentley Applications Provide Integrated Solution
Already familiar with Bentley applications, DTK Hydronet selected ProjectWise and OpenFlows to develop a GIS, cloud-based platform to manage information and perform hydraulic modeling. Using ProjectWise to host the digital asset repository provided a single source of truth of all project data and models accessible to DTK Hydronet, the contractor, and the utility. The platform improved collaboration and issue resolution to keep the project on track. They used OpenFlows WaterGEMS to develop the initial hydraulic model and generate over 100 scenarios to improve the utility and contractor’s project understanding. Using OpenFlows HAMMER, they conducted detailed transient and surge analysis to safeguard the network. They integrated all asset data and models into a comprehensive 3D utility model accessible via mobile and web-based devices.
