East Durham Waterline Replacement
Water Management’s project contractor, Hydromax USA, is planning to perform fire hydrant assessments and flushing within the East Durham project area. The work is scheduled for Monday September 30, 2019 and is expected to be completed within one week. The work will include a detailed assessment of each fire hydrant within the project area to document the existing conditions and paint the hydrants. In addition to the assessment, Hydromax will operate each hydrant to measure the flow and pressure of the water. During the measurements, water will be flushed from the hydrant to the ground surrounding the hydrant. No disruption to services are expected during the assessment and flushing operations.
Water Management's project contractor, Hydrostructures, is planning to perform dye testing of select sanitary sewer services within the East Durham project area. This work is scheduled to begin Monday August 19. No service interruptions are anticipated; however, if no cleanout near the street exists, representatives may need to access inside buildings for this work. If inside access is needed, a time will be scheduled when the resident/property owner is available. Door hangers will be placed at properties where dye testing will occur.
The departments of Water Management and Public Works are assessing required improvements to the existing water, sewer, and stormwater infrastructure between Fayetteville Street and Alston Avenue, and 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 City’s stormwater sub-consultant, Kimley-Horn and Associates, will begin going door to door on Tuesday, May 28 to collect signed stormwater Right of Entry agreements from property owners. Only a small number of property owners within the East Durham area will be impacted by this pre-assessment activity. We appreciate your time and assistance returning these forms in a timely manner so that we can move into the Assessment phase.
The Assessment phase will begin July 17, 2019 and continue through early spring 2020. Assessment activities will include survey, water meter, fire hydrant and water valve assessments, CCTV, stormwater and sewer main inspection, flow monitoring, dye testing, and smoke testing as necessary. 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 will recommend a design and construction phasing plan to complete all required upgrades to the existing infrastructure within the study area over a five-year period. The project brochure at right provides more information on the Assessment phase.
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 four to six phases each lasting 18-24 months. Phase 1 construction is expected to begin in mid-summer 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.
