INNOVATION IN WATER, WASTEWATER, AND STORMWATER NETWORKS
Dee Valley Water plc
Network Spatial Analysis
Wrexham, United Kingdom
Dee Valley Water supplies more than 23 million tons per year of water to
258,000 customers in North East Wales and North West England, United
Kingdom. The 2,000-kilometer network is managed using MicroStation and
Bentley Water. To meet regulatory reporting requirements and maintain up-to-date asset information, the company introduced spatial analysis capabilities
with Bentley Map.
The Bentley solution allows Dee Valley Water to spatially reference overlay
polygon datasets such as water quality boundaries, soil type boundaries, and
district meter areas. Polygon attributes are assigned to network assets based
on spatial location. Reports detailing which assets are within each polygon
dataset are exported and processed for regulators. Assets are re-assigned on
the fly when polygon boundaries change.
Delhi Jal Board
Master Plan for Improvement of Water Supply System in Delhi
Delhi Jal Board supplies potable water to Delhi, India. Known issues in the
7,000-kilometer water distribution network included high non-revenue water,
supply shortages, inefficient equipment, and inadequate operation and
maintenance. The master plan for system improvements was based on a forecast
population of 26 million and consumption of 60 gallons per capita per day.
Delhi Jal Board used WaterGEMS to convert GIS data into a hydraulic model,
perform hydraulic analysis to identify network inadequacies, estimate and
distribute demand, and optimize network parameters. This lowered non-revenue
water, electricity consumption, and service outages. Distribution facilities were
planned to meet a total water demand of 1,560 million gallons per day.
