State-of-the-art backup for a vital reservoir

Our team identified an alternative intake site and pipeline route that eased construction and minimized environmental impact.

Opportunity

The man-made Deer Point Reservoir, formerly a saltwater estuary, provides 25 MGD of drinking water to residents of Bay County, Florida, and up to 40 MGD during the summer tourist season.

A report commissioned by the Northwest Florida Water Management District showed that a 100-year storm event, roughly equivalent to a Class 3 hurricane, could potentially overtop the dam with storm surge, making the raw water in the reservoir unusable.

Solution

Bay County chose the design-build delivery method for its Alternative Water Supply Project, designed to deliver about 50 MGD of raw water through approximately 11 miles (16 kilometers) of pipeline without causing significant harm to water resources or the ecology of the area.

Our team assessed the challenges of the project, including budget and schedule, environmental impacts, permit lead times, route selection design opportunities, constructability, traffic issues, and availability of specialty contractors and consultants.

Outcome

Mott MacDonald met the goal of building a state-of-the-art facility under budget and four months ahead of schedule. Our team established an alternative intake site and route that, although slightly longer, drastically reduced environmental impacts and constructability issues.
