Key Points

• Addressing Nitrogen Pollution: The project aims to reduce nitrogen pollution in Barnstable's coastal embayments, primarily caused by septic systems. Sewers are deemed necessary to meet Total Maximum Daily Loads (TMDLs) set by regulatory agencies.
• CWMP Overview: The CWMP is a 30-year plan to install approximately 190 miles of sewer lines, impacting nearly 12,000 properties. The Route 28 West project is a significant part of Phase 1.
• Project Objectives: The project will expand municipal sewer lines along Route 28, creating infrastructure for further westward expansion and decommissioning the Marson's Mills wastewater treatment plant.
• Infrastructure: The project involves 13 miles of new sewer pipes, two force mains, and four new pump stations. Construction, particularly on Route 28, is planned for nighttime hours to minimize traffic disruption.
• Pump Stations: Four pump stations are detailed, including their locations, service areas, and designs. Renderings and site plans are shown for each.
• Marson's Mills Wastewater Treatment Plant Decommissioning: The existing plant will be decommissioned and connected to the new sewer system, with potential repurposing of the building for school use.
• Funding: The project's estimated cost is over $59 million, funded through a combination of town appropriations, low-interest loans from the Clean Water State Revolving Fund, and subsidies from the Cape Cod and Islands Water Protection Fund.
• Schedule: Design is nearing completion, with bidding anticipated in spring 2025, construction starting in fall 2025, and project completion targeted for 2028.
• Sewer Connection Process: A six-step process is outlined, including notification, hiring a licensed installer, septic system abandonment, inspection, activation, and billing. Costs are capped at $10,000 per sewer unit.
