Infrastructure Projects
System improvements, upgrades and projects
We are continuously working to maintain and improve the water system. Some of the major projects we are currently working on involve the installation of new, or the replacement of existing, equipment and facilities needed to provide safe, reliable water service.
Proposed Water Transmission Main - Hemlocks Reservoir, Fairfield to Coleytown Road, Westport
Aquarion Water Company (AWC) has been working on a long-range plan to strengthen the resiliency of the existing water system in the Fairfield County area. AWC is currently working with AECOM, a consulting engineering firm, to design a new 36-inch diameter water transmission main and the initial phase of the work is located in Fairfield and Westport.
The pipeline design and construction is divided into phases. This particular phase of the work in Fairfield and Westport will begin at the Hemlocks Reservoir on Black Rock Turnpike and proceed approximately 4.4 miles into Westport to an underground connection at the intersection of Coleytown Road and Easton Road(CT Route 136). There will be another phase of work that will extend the new 36-inch water transmission main from the location on Coleytown Road to the existing water storage tanks on Belden Hill Road in Wilton.
- Beginning in Fairfield, West on Hemlock Road
- North on Burr Street
- West on Aran Hill Road
- North on Congress Street
- West on Longmeadow Road
- South on Redding Road
- West on Catamount Road into Westport
- In Westport, Southwest on Easton Road (CT Route 136)
- Ending at the intersection of Coleytown Road and Easton Road
- A surveying crew from Pereira Engineering will document the existing conditions along the route and a soil scientist will be flagging the inland wetlands within the street right-of-ways. Wetlands within the public right of way adjacent to roadways along the route will be flagged.
- Soil borings will be taken to investigate the soil conditions. First, an engineer from AECOM will mark out the locations of the borings. A crew for Corbuilt LLC will confirm locations of buried utilities using ground penetrating radar. Prior to drilling, at particular locations, a vacuum excavation crew from Terracon Consultants, Inc., a boring contractor, will carefully remove pavement and the soil underneath to confirm there are no utilities at that location. Next, Terracon, will drill approximately 72 test borings.
- Later in the summer, DAS Construction, Inc. will excavate test pits by vacuum methods to allow AECOM access for measuring specific buried utilities of interest.
- Traffic control devices such as cones and signs will be provided during the drilling program. In addition, it is anticipated that police details may be required and it may be necessary to close a lane of traffic. The subcontractor is responsible for coordinating traffic detail.
- The project schedule is as follows:
- On-Site Design tasks – Spring and Summer 2025
- Final Design complete – February 2026
- Begin Construction in Spring 2026
- Construction activity may be reduced in the winter months for inclement weather. Due to the large pipe diameter and the significant length of the pipeline, it is expected that this phase of the pipe installation will be completed by the end of 2027.
