Montague staff out in field performing night flow isolations at manholes
Wright-Pierce and the Town of Montague DPW will be in the Turners Falls and Millers Falls areas for two consecutive evenings performing sewer night flow isolations (NFIs) next week.
The tentative times are:
10pm June 14th (Tuesday) through 6am June 15th (Wednesday)
10pm June 15th (Wednesday) through 6am June 16th (Thursday)
Night flow isolations involve opening sewer manholes and using a flow meter to measure flow. The Town needs to perform NFIs at night so that they can find extra water (groundwater infiltration) that is coming into the sewer system when they typically see very low sewage flows (people are sleeping and not flushing toilets and doing laundry typically!). There will be no additional noises to be concerned about. There may be some additional lights (on trucks, flashlights) to help staff see what they are doing. Each “set-up” is 30-45 minutes or so. The staff will perform about 30 “set-ups” each night at different manholes in the two village areas.
The exact starting time and meeting location for each night is still TBD.
If you have any questions, please reach out to the DPW.
