Town discusses sewer odors and low-cost mitigation; $20,000/year odor-control chemicals used
Summary
Board discussed a July complaint about sewer odor and noted the town spends about $20,000 per summer on odor-control chemicals; staff discussed building a vegetative 'peat filter' planter as an inexpensive way to control hydrogen sulfide emissions and agreed to pursue joint sewer district meetings.
Board members reviewed one July complaint about odors from the joint sewer district and discussed operational steps taken to mitigate smell. Staff reported the town spends roughly $20,000 each summer on odor-control chemicals and that portable feed systems at pump stations have been effective, while also noting sludge removal events can temporarily increase complaints.
A staff member described a low-cost mitigation option being considered: "It's building a big planter and filling it with peat moss, keeping it moist, connecting it. It's kind of an inexpensive way that you can control hydrogen sulfide." The board agreed to convene a joint sewer meeting in September to consider options and rate-setting and to weigh the potential cost (estimated in the $20,000–$30,000 range) of more extensive engineering work such as covering pump stations.
