East Durham Waterline Replacement
The departments of Water Management and Public Works are improving water, sewer, and stormwater infrastructure between Fayetteville Street and Alston Avenue. Additional improvements will stretch from Linwood Avenue to Hopkins Street. The study area for the improvements can be viewed on the project area map. The project area does not include areas that were previously rehabilitated or replaced.
Public Works is responsible for managing the City’s rights-of-way including roadway, sidewalk, and stormwater infrastructure. Water Management has worked with Public Works to verify that this infrastructure is also evaluated and assessed within the boundaries of our East Durham project. Roadway and sidewalk infrastructure in need of replacement and/or improvement will be included in water and sewer rehabilitation projects. Two areas within East Durham have already been identified for stormwater infrastructure improvements to address flooding and aging infrastructure. These areas are: 1) Belt Street between Morning Glory Avenue and Franklin Street; and 2) Lincoln Street between Simmons Street and Linwood Avenue.
The Assessment phase of this project was conducted in the summer 2019 through spring 2020. Assessment activities included survey; water meter, fire hydrant and water valve assessments; stormwater and sewer main inspection; flow monitoring; dye testing; and smoke testing. The project will replace existing water, sewer, and stormwater infrastructure in the project area that have reached the end of their useful life. As part of the Assessment phase, the consultant developed a design and construction phasing plan to complete all required upgrades to the existing infrastructure within the study area over a five-year period.
Following the Assessment phase, the consultant will move into the Study/Design phase, which will include geotechnical borings and Level A SUE. The City anticipates that the required improvements will be packaged into five to six phases each lasting 18-24 months.

The Phase 1A project area is shown in the map to the right. This area is currently in the Design phase. As part of this work, Water Management’s contractor, Hydrostructures, will be conducting additional assessment work in select areas between Linwood Avenue and Dupree Street in April 2021. The assessment work will include inspection of sanitary sewers with internal cameras to determine the condition of the pipes and dye testing to determine the location of active sewer laterals. During dye testing, bright colored, non-toxic dye is introduced to the building sewer lateral through the cleanout. If there is no cleanout, dye can be flushed through sinks or drains inside buildings. A camera in the sewer records where the dye enters the sewer to confirm where the building lateral is connected to the sewer main. No service interruptions are anticipated; however, representatives MAY need access inside buildings for this work if no cleanout near the street exists. If access inside is needed, a time will be scheduled when the resident is available.
Beginning in the end of April 2021 and through May 2021 Stewart and Falcon Engineering will also be performing investigations in the Phase 1A project area to assist with the project design. Stewart will be performing subsurface utility investigations and Falcon Engineering will conduct geotechnical investigations. Disruption of existing utilities is not anticipated during these investigations. Impacts will be limited to construction related noise and minor traffic control near each investigation location. Night work is not anticipated at this time.
Door hangers will be distributed seven days prior to any work anticipated in your area.
Phase 1A Construction phase is expected to begin in fall 2021
Discolored Tap Water - What to Do
Part of the Assessment phase will include valve operation and assessment of water mains in the project area. Valve operation causes a change to the direction of water flow and sometimes causes an increase in velocity in the mains in the surrounding area. Slight water discoloration is entirely normal for up to 24 hours following valve operation. Customers can flush water in their private lines by turning on cold water from several faucets at once to flush discolored water out of the interior plumbing system. Customers whose water service is temporarily interrupted as a result of valve operation should flush their lines as an extra preventative measure, by running cold water through showers, bathtubs, or other fixtures at full force. This helps clear lines of air and sediment that may have entered the line as a result of the service interruption.
