INNOVATION IN WATER RESOURCES
Cradle Coast Water
Barrington treatment Plant Backwash Process upgrade
the Barrington treatment Plant is a dissolved air floatation and filtration
configuration with a design capacity of 3. 5 million liters per day. Filter run
times were gradually reducing, leading to inadequate plant performance. Off-line, structural inadequacies mandated a full plant upgrade.
A model was created through WaterCAD using pipe lengths, inside diameters,
and construction elevations. The model showed that a small variation in pipe
diameter downstream of the bypass valve had a significant bearing on bypass
flows. During commissioning of the valve control system, the valve position
was found to be within 10 percent of calculated value.

Davao City Water District
Installation of Pressure Enhancers at Different Strategic Locations
Davao City, Philippines
to sustain required residual water pressure during peak hours at remote
service areas, the Davao City Water District installed an in-line booster
station. The alternative of increasing the size or number of transmission
pipelines would have required a huge investment and caused traffic
congestion during construction along major thoroughfares.
WaterCAD and WaterGEMS were used for hydraulic modeling, analysis, and
design, resulting in fast modeling of the water supply system’s physical attributes
and quick results of analysis and design works. Using MicroStation PowerDraft
saved up to 70 percent of the time required for drafting work compared to
conventional methods. The overall return on investment was 45 percent.
