2012 Structural Lining Program


Existing water mains in the Town of Irondequoit on St. Paul Boulevard, Parkview Terrace, Wabash Avenue, Beach Terrace, Lake Terrace, Centre Terrace, North Terrace, Summerville Drive, Second Street, Third Street and a cross county main running from Timrod Drive to Parkview Terrace will be cleaned and lined by a contractor hired by the Water Authority. 

As part of trying innovative methods, MCWA is conducting a pilot program using a cured-in-place-pipe (CIPP) structural lining product. The CIPP liner is either pulled into the existing pipe using a winch, or inverted inside the existing pipe by using water or air while under pressure. Once installed, the lining is cured using warm water or air. When cured, the CIPP is considered independent from the existing pipe and is equivalent to a replacement pipe. Along with reducing the possibility of future water main breaks, the smooth interior of the CIPP will improve water quality and enhance the ability to maintain pressures and flow for firefighting purposes.

A cleaning and lining project requires only small excavations to access the main at about 500 foot intervals and at locations where water mains intersect.  Water services can be reinstated from within the water main by a remote controlled robot.  Occasionally some services need to be dug up at the water main.

The first step of the contractor’s work is to lay temporary bypass piping. This temporary piping is chlorinated, flushed, and health sampled by the Department of Health. After the health samples are approved, each customer’s home is temporarily connected by a hose to the bypass system. Excavations are then made at selected locations, and the main is cut to allow access for cleaning and lining equipment. A scraper is pulled through the pipeline until all tuberculation is removed and other preparation work is done, and then the main is flushed clean. The contractor then installs the CIPP lining system into he existing main. If conditions warrant, old fire hydrants and valves are replaced. After the lining cures, the lining is inspected with a video camera and then the main is pressure tested for leaks. Before customers are returned to the refurbished main, it is chlorinated, flushed, and tested by the Department of Health.

During final restoration, the temporary bypass system is removed and disturbed areas are restored to their preconstruction condition. Temporary asphalt is removed, and permanent asphalt is installed in paved areas. Lawn areas are graded and seeded, and the contractor is responsible for getting all seeded areas to grow properly.

Additionally, as part of this project a short section of existing 4" water main on Summerville Drive near house #139 and #151 will be replaced. 


The schedule depends on a number of factors, but we anticipate our contractor starting work in June and finishing by November. Minor restoration work may occur in the spring of 2013.

Project Bulletin

Q: What determines replacement, relocation or relining of water mains?
A: Evaluation is primarily based on pipe age, the occurrence of breaks and repairs, and future hydraulic considerations.

Q: Will our water services need to be repaired?
A: The Water Authority is typically responsible for the portion of each building's water service that is in the public right-of-way or water main easement, up to and including the curb stop. The Water Authority will replace its portion of your service line and the curb stop during the project if needed.

Q: Will I have water service during the project?
A: If the water main that serves your home is being replaced, you will be notified in advance of any non-emergency service outages. Service to homes is temporarily shut down during installation of new service connections to the curb stop and during tie-in connections at the end of the water main installation.

Q: What are the advantages of cleaning and lining water mains?
A: Along with improved water quality, the ability to maintain pressures and flow for firefighting purposes is enhanced by the smoother pipeline interior.

Q: How are sections of pipe removed and replaced?
A: Access excavations are made approximately every 500 feet and at locations of pipe intersections. Pipe sections are cut for removal utilizing pipe saws. The removed pipe sections are cleaned and lined above ground and re-installed.

Q: How soon after lining can the pipeline be put back in service?
A: Service can usually be restored within 48 hours at operating pressure.

Will there be open trenches at night?
A: No. The site must be left in a safe condition by the contractor and trenches will be protected with orange construction fence.

Q: Is the contractor penalized if the project is not completed on time?
A: Yes, there are provisions in the contract to ensure the project is completed in a timely manner.

Q: Will damage to my lawn be repaired?
A: Yes, lawn areas are graded and seeded and the contractor is responsible for proper regrowth.
