Fairfield CT Wastewater Treatment Plant (WWTP)

Hardening Project Sea Level Rise

Seaside Towns across New England have begun to harden themselves against future sea level rise. In many cases the historical sprawl of development has made it difficult to relocate important utilities such as water and wastewater treatment plants. Many municipalities are protecting their investments in utilities to insure they will function for years to come.

The Fairfield WWTP Hardening Project installed 2,400 linear feet of cantilevered steel sheet pile walls to encompass their Department of Public Works campus. The infiltrated water will be collected and dewatered using pump stations.  Both pump stations require high volume dewatering systems to allow for construction.

Recon Outfitters designed a treatment system to fit within the tight confines of an active WWTP, capable of treating up to 700 gallons per minute (gpm), fed by two dewatering wells positioned adjacent to the work area for the installation of the pump station.  The system consisted of three 21,000-gallon RECON frac tanks interconnected, a 4-inch diesel pump, a duplex multi bag filter, 6 skid-utilizing ten micron bag filters, and 6 pressurized vessels containing 5,000 pounds of granular activated carbon media each set up two in a series,  followed by a flow meter totalizer prior to discharge.

RECON helps contractors operate, optimize, and maintain the system to allow the contractor to focus on the construction portion of their work, while RECON keeps the water flowing.
