The contract involved excavating two access pits for cleaning, CCTV inspection, and CIPP lining the approximately 700 linear feet of sewer force main. It also included installing two new sections of 10-inch PVC sewer force main at the access pits to connect to the rehabilitated 10” CI force main, along with associated fittings and appurtenances. As part of this work, the General Contractor, Insituform Technologies LLC, furnished, installed, and maintained a temporary sewer bypass pumping system, which extended from a manhole outside of the Holmes Point Pump Station to a discharge manhole located at the intersection of Sandwich Street and Bay View Avenue.

The General Contractor substantially completed the project on April 9, 2024.

Over the past twenty years, the vacuum system has experienced system-wide failures from a variety of causes including storm-induced electrical malfunctions, extreme weather and storm runoff, and tidal inundation. EP evaluated transient electrical supply issues; compared system design standards to installed operating conditions; assessed operations and maintenance practices, troubleshooting, alarm monitoring, and emergency response; identified inflow contributions, and reviewed planned upgrades.

EP’s prioritized recommendations will increase the resiliency of the system under all operating conditions, while making the system more resilient to instantaneous disruptions from weather and tidal disruptions.

The site drainage was modified to prevent any flooding within the flood barrier wall during storm surge events. The existing catch basin discharge in the north corner of the paved area was fitted with a 12-inch gate valve. The manual gate valve will isolate the catch basin and prevent flooding from outside of the flood barrier wall backing into the WSPS yard through the basin. While the existing catch basin is isolated from the drainage outside of the WSPS, storm water will be collected into the existing catch basin via the existing on-site storm water collection system and will be pumped out of the basin with a trailer mounted dry-prime trash pump (supplied under this project).

The perimeter wall was designed as a reinforced concrete foundation and wall with New England stone veneer facing along the building. As part of the aesthetic design, the permanent flood barrier wall structure included a granite stone cap.

As part of this project, EP assisted the Town with obtaining a $2.5 million dollar grant through the MassWorks Infrastructure Program and a $350,000 grant through the CARES Act program. The General Contractor on this project, C. Naughton Corp of Bridgewater, MA took delivery of the new Gorman-Rupp pump station equipment for the new Campanelli Parkway Pump Station.

Phase 1 of the expansion was separated into two contracts; Contract 1 involved the installation of 9,200 LF of 8-inch PVC gravity sewer main and 4,300 LF of 6-inch PVC sewer force main, along with associated services, manholes, and appurtenances. Contract 2 consists of the installation of a pre-packaged sewer pump station inside the Campanelli Business Park. Both projects were bid in 2021 and awarded under budget. Construction for Contract 1 was completed in 2023, while construction of Contract 2 is nearing completion and is expected to be completed in early 2024.

The Town responded to two emergency ruptures of the sewer force main in 2016 and 2017, which ultimately led to the Town retaining EP to perform an assessment of the sewer force main to look at potential options for rehabilitation and replacement.

After assisting the Town with the design and permitting of a new sewer force main comprised of 20” PVC and 20” HDPE sewer main piping, EP is currently providing construction administration and oversight services for its replacement. With C. Naughton Corp. of Bridgewater, MA, construction of the new sewer force main began in the Spring of 2022 and is scheduled to be commissioned during the Summer of 2023.

The City, in part with funding from the U.S. Economic Development Administration, is improving the resilience of the WPCF for future coastal storms and sea level rise. The City’s general contractor, Methuen Construction, has installed the earthen berm along the western side of the site. Concrete work for the flood wall along Essex Avenue is proceeding and the steel sheet-pile wall along eastern side of the site will be completed soon.

Construction is anticipated to be complete later this fall and include installation of four self-deploying flood gates for vehicle and personnel access points to the WPCF.

To protect Vineyard Haven Harbor, the Town is initiating a program to connect boat sewage pump-outs from private marinas to the sewer system. The municipality is leading the way by connecting the Town dock and Harbormaster pump-out facility at Owen Park. The project entails constructing 800 feet low pressure sewer via horizontal drilling, including using an abandoned water main as a conduit for 400 feet of the pressure pipe, and a new grinder pump chamber at the pump-out tank.

The project was constructed on a tight schedule to allow for the paving of Main Street prior to the annual Memorial Day March to the Sea by Tisbury School students. Children in grades K through 8 toss flowers into the harbor at Owen Park to honor those who have given their lives for their country.
