Head of the Westport River Stormwater Project

Overview

The Buzzards Bay NEP is working with the Westport River Watershed Alliance (WRWA) and the Town of Westport to address stormwater pollution currently discharging into the Westport River at the Head of Westport village. Phase 1 of this project has already been complete with the construction of a stormwater wetland system for the discharge along the east side of the river. Phase 2 is now in the beginning stages and will involve the reduction and remediation of stormwater flow to the west side of the river. Phase 2 encompasses two stormwater pipes, HW1 and HW2 (see maps), the largest of which is HW1. Preliminary site investigations by BBNEP and WRWA indicate that this drainage system begins at the high point of Old County Road, just east of Route 88 and includes drainage from Jason Drive, the Westport Middle School/Library complex, and some of the Drift and Gifford Roads area. The smaller pipe (HW2) drains a portion of Drift Road.

The BBNEP, the WRWA and the town have been working on developing conceptual strategies to address this stormwater issue, especially the contribution made from the middle school and library. The WRWA is providing support by issuing a Request for Proposals to develop an existing conditions plan for the contributing watershed. To support the town and WRWA's efforts we have created this web page to make available information about the project and to disseminate information to our partners, the public, and other interested parties.

Project Goals

The overall goal of this project is the reduction of stormwater pollution at the Head, with the primary focus on bacterial loading. To accomplish this goal, two initial objectives must be accomplished. First, data and information must be collected to determine the feasibility of stormwater remediation for the road drainage to HW1 and HW2. This information will be used at a later date for design purposes. Second, data and information must be collected to prepare designs and a bid package for the storage and treatment of stormwater runoff generated from the Middle School and Library property (MS&L Complex). It has already been determined that a significant amount of stormwater flows off this site and contributes to the overall detriment of the river. A stormwater treatment system that both reduces stormwater flows to the river, and stores and recycles that rainwater for irrigation of the schools recreational fields accomplishes two worthwhile objectives - reducing well water use and reducing pollutant loads. It also makes treating the water from other parts of the watershed easier because a smaller combined volume must be treated before discharge to the river.

Schedule

Once the existing conditions plan is developed, the Buzzards Bay NEP hopes to issue an RFR for stormwater treatment designs for the Middle School and Library Complex. More information about this project will be posted as those other efforts proceed.
