Town of Germantown

WWTP Upgrades

Project Cost:

The Town of Germantown’s wastewater treatment facility, constructed in 1997, had surpassed its expected lifespan, and its steel tanks and components were rapidly deteriorating due to oxidization and corrosion.  The flow equalization tank and the aerobic digester were delaminating and had become structurally unsound, making operational maintenance difficult and potentially dangerous. The Town’s two wastewater pump stations were also in a state of severe deterioration and threatening mechanical failure.  Working with the Town, Delaware Engineering secured an Engineering Planning Grant in order to study the situation and determine a recommended solution.

The engineering report evaluated alternatives and determined that the steel tanks used for flow equalization, the sludge holding tank, and the primary and second clarifiers needed to be replaced with concrete tanks. Those upgrades, plus the replacement of malfunctioning pumps, blowers, and other underperforming equipment, would cost approximately $2.5 million. The report further sought to identify opportunities for cost-savings by retaining those systems that still functioned well, e.g., the biological process, which continued to produce effluent that in most cases exceeded the requirements of the plant’s SPDES permit.

The report’s findings were used to secure a WIIA grant in 2018 totaling $625,000 (25% of total project costs) and subsidized-interest financing for the project.

Delaware’s scope of services included all planning, grant-writing, SEQRA environmental review, design, permitting, grant administration, construction administration, construction inspection, and start-up assistance.  Construction is anticipated to be complete mid-2022.
