Dennis Harwich Yarmouth Clean Waters Community Partnership The breakdown of Dennis' sewer plan. The town hopes to start to address nitrogen pollution in the southern part of Dennis. Dennis voters rejected a more than half-a-million dollar funding request to begin designs for a sewer project at Saturday's Town Meeting. The proposal needed a two-thirds majority vote to take $660,000 the town has set aside for wastewater initiatives, and put it toward the design of a sewer collection system in the southern part of town. Select board member Paul McCormick says the no vote pushes back the town's already overdue goal of reducing nitrogen pollution. And he's disappointed.
