MELROSE — The City of Melrose’s Public Works Department has started the first phase of a sanitary sewer investigation program throughout the city.

The purpose of the project is to identify problem areas of the sewer system that are in need of rehabilitation and/or repair in an effort to prevent infiltration from entering into the pipes. Infiltration is clean water from below the ground, known as groundwater), that enters the sewer system through defective sewer pipes and structures. This “clean” water takes up space or capacity in a pipe that would normally be available for wastewater. It can cause the pipe and its service connections to back-up and potentially overflow during extreme wet weather conditions, and it costs the city’s sewer ratepayers money to send to the MWRA sewer system.

One step in this program is to conduct flow isolation. Flow isolation is a method of quantifying the amount of infiltration in a sanitary sewer system. Flows in the system are measured during off-peak times, typically between 12 a.m. and 6 a.m. Normally people are sleeping during this time and if there is flow in the sewer system, it can be assumed to be largely infiltration.

Beginning on Sunday, April 9, 2017, crews from Inland Waters, Inc. of Johnston, Rhode Island, will be present in the neighborhoods between the hours of 11 p.m. and 7 a.m. A representative from Weston and Sampson Engineers, Inc., a wastewater consultant, and/or a representative from the city will also be present for the duration of the flow isolation.

It is likely that residents will see trucks and workers present in the street during these hours. The workers will be required to remove the existing sewer manhole covers to enter the sewer system and some minor noise disturbances may result. It is expected that all of the flow isolation will be completed in approximately three weeks.

“We ask for your patience and understanding while this work is completed,” said City Engineer Elena Proakis Ellis in a press release.

If residents have any questions or concerns, people should call Project Engineer Scott Dixon at (781) 979-4173 or Ryan Henley of Weston and Sampson, the City’s wastewater consultant, at (860)-967-4651.
