INNOVATION IN WATER, WASTEWATER, AND STORMWATER NETWORKS
Sharjah Electricity and Water Authority
Management and Planning of Sharjah City Water Network
and Water Authority developed a model of the city water network that is more
than 2,000 kilometers long. Project data was integrated with a single GIS
database for updating, upgrading, and sharing with other departments of the
Sharjah government.
The project team migrated existing network data from CAD files to
WaterGEMS. This allowed for network management and monitoring (flow,
pressure, leaks), network analysis (demand, criticality, scenarios), network
design and modeling, and network maintenance and expansion (demand
forecasts). Through network analysis results and modeling, the firm improved
water flow and reduced leakage.
Stearns & Wheler GHD
Sanitary Sewer Evaluation and I/I Reduction Study
Allegany County, Maryland, United States
This project addressed sanitary sewer overflows due to excessive rainfall-
derived inflow and infiltration in the collection systems for the Jennings Run-Wills Creek and Bedford Run Sanitary Districts in Allegany County, Md. Stearns
& Wheler performed infiltration and inflow analyses, evaluated the sewer
systems, and developed a rehabilitation action plan.
As part of the Sanitary Sewer Evaluation Study, a dynamic hydrologic and
hydraulic model was developed for each of the collection systems using
SewerGEMS. Using the model to project flow rates and volumes for a selected
design storm, the study team evaluated alternatives for limiting peak overflow
rates. The most feasible solution involved rehabilitation and replacement of
piping and incorporation of storage for stormwater retention.
