CDM Smith of East Hartford and Martinez Couch & Associates LLC of Rocky Hill have been contracted by West Haven to conduct a sewer system study for locating sources of stormwater inflow to the city’s sanitary sewer system.
The three-week study, overseen by CDM in designated Allingtown neighborhoods only, will attempt to locate direct and indirect connections from sources, including catch basins, roof drains and broken sewer pipes. One of the methods used is smoke testing, performed by Martinez Couch.
During testing, white smoke is introduced into the sanitary sewer system via a smoke-generating machine at an existing maintenance hole. White smoke is vented from holes in maintenance hole covers on the street and plumbing vent pipes on or near the roof surface.
The procedure is normal and not cause for alarm.
