The CWMP is a town-wide plan to protect Barnstable’s coastal waters, ponds and drinking water by managing nutrient pollution from wastewater. To accomplish this, the plan calls for an expansion of the Town’s wastewater infrastructure (sewers) as well as other innovative and nature-based approaches such as inlet dredging, cranberry bog conversions and use of nitrogen removing septic systems.
The 30-year plan is comprised of three 10-year phases. Each phase consists of multiple sewer expansion projects designed to reduce nutrient pollution in embayments to a level consistent with regulatory thresholds known as Total Maximum Daily Loads (TMDLs). The plan also protects water quality in ponds, and drinking water sources.
Projects that make up Phase 1 of the plan are shown on the map below. The table shows the estimated timeframes for permitting (yellow), design (blue) and construction (red).
