Notice of Sewer Inspections-Greenwich Avenue Area

GREENWICH AVENUE AREA INSPECTIONS      SEE MAP BELOW                         

The Town of Greenwich is undergoing investigations to reduce inflow and infiltration to the sewer system in the downtown area of Greenwich, which is centered around Greenwich Avenue, as well as perform a conditional assessment of the sanitary sewer mains to maintain a good overall system service life.


Inflow is ground or storm water that is discharged to sanitary sewers from sources such as basement sump pumps, floor drains, roof leaders, foundation and yard drains, and catch basins. Infiltration is ground or storm water that enters the sewer system through pipe joints, cracks in pipes, manholes, etc. During rain events, high sewer flows generated from these sources can cause overflows of the sewer collection system. These overflows have a negative effect on the ecology of the Long Island Sound, reduce the quality of the waters for recreational activity, and provide unhealthy environmental conditions for our residents and businesses.


WHAT?  - CLOSED-CIRCUIT TELEVISION (CCTV):

The Wastewater Division’s engineering consultant CDM Smith and their subconsultant National Water Main will be cleaning the sewer and televising the condition of the sewer main and the sewer laterals. In addition, the sewer laterals will be located using a handheld meter. Temporary paint markings may be used during the process of locating the laterals. This paint is necessary for us to identify locations and be able to properly map/survey the area. The temporary paint will eventually wash off/wear off and is not permanent.


WHERE?

Streets where CCTV work will occurArch Street, Benedict Place, Greenwich Avenue, Havemeyer Place, and Lewis Street - Please see attached map for the work areas.  Work is scheduled to start on Greenwich Avenue (on the north side near West Putnam Avenue) and head south along the avenue.  Benedict Place will be performed after the Greenwich Avenue work is completed.


WHEN?

Activities are scheduled to occur starting Monday, June 17, 2019 and run through July 3, 2019 weather permitting.  Normal hours of work will be between 7:00 a.m. and 5:00 p.m. Additional work may be necessary after July 15th to complete field investigations after the sidewalk sales are complete. Additionally, later in 2019 there may be follow-up work including smoke testing to identify potential inflow sources. Separate communications will be distributed before smoke testing work begins.


WHAT DO YOU NEED TO DO?

You can continue to use water freely during the work.


We will do our best to minimize the impact to residents and we appreciate your cooperation. Please expect to see workers from our Consulting Engineer (CDM Smith), the subcontractor performing the CCTV inspection (National Water Main) and Town of Greenwich DPW Sewer Division staff in the area during the work. There will be some temporary disruptions to a few parking spaces as the work progresses each day.


Any questions, please feel free to contact the Sewer Division at 203-622-7760. Thank you.
