The City of Somersworth, New Hampshire elected to upgrade its existing wastewater treatment facility (WWTF) to improve operational efficiency. Through the use of a $10.54 million Clean Water State Revolving Funding loan agreement, the Somersworth WWTF underwent comprehensive upgrades.

Victaulic’s grooved solutions were utilized on the return active sludge (RAS), waste activated sludge (WAS), thicken sludge line, and plant water systems throughout the Somersworth WWTF. This included the use of grooved couplings, fittings, and valves, listed below. The coupling and valve design, materials, and testing conform to the requirements of AWWA for water and wastewater treatment services.

On this upgrade, Victaulic’s solutions for the wastewater market provided numerous value engineering benefits including ease of installation in the existing facility footprint, vibration attenuation, and elimination of bulky expansion couplings.

The use of Victaulic solutions eliminated the need for dismantling joints which allowed for a reduction in the system footprint and total install cost. Additionally, future system expansion and system maintenance are possible through the grooved design as Victaulic couplings deliver a union at every joint. Victaulic Style 31 Coupling, Series 317 Check Valve, and Style 365 Plug Valve provided valve-engineered benefits to the Park Creek Sewage Treatment Plant that will be realized for years to come.
