2016 Construction Projects

2016 Street Rehabilitation

– Gleahaven Road, Chicago Avenue South, and Cross Street will be fully reconstructed. Work on Lake Street, between Barry Ave and the Ferndale Road railroad crossing, Manitoba Avenue, Indian Mound (behind City Hall), and Central Avenue South will involve the milling and overlaying of the existing pavement surface only, with minor drainage repairs. Additionally, the City’s parking lot, behind CoV and Steele Fitness, will be reconstructed.  This project is proposed to be awarded to a contractor in early May. Work will likely begin in early July and is expected to be completed in September.

2016 Sewer Lining

– Approximately 6,000 feet of sanitary sewer will be lined on Edgewood Ave. S., Highland Lane, Lakeview Lane, Westwood Lane, Highcroft Lane to Peavey Lane, Bushaway Road, Margaret Circle, and Gleahaven Road. This project is proposed to be completed by the end of October.

Cured-In-Place Pipe Process
Cured-in-place pipe (CIPP) is a trenchless rehabilitation process used to repair existing pipelines using a resin (styrene) saturated felt tube.
  1. Cleaning and Inspection: Prior to lining the existing sewer, crews clean the pipe using high pressure water hoses and video cameras to inspect the pipe condition.
  2. Pipe Lining: Crews place a flexible liner into the existing sewer. Steam or heated water is forced into the liner, pushing the liner tightly against the existing sewer walls. The heat causes the liner material to cure, creating a new pipe within the existing sewer that is free of cracks and holes. Crews then use pumps and hoses to re-route sewer flows, ensuring sanitary service to customers.
  3. Reinstating Laterals: Crews cut open the existing lateral pipes serving each home, using a remote operated cutter and video camera.
  4. Lateral Connection Sealing: Another contractor may inject grout to completely seal the connection and ensure no infiltration reoccurs.

The actual pipe lining process typically takes less than one day to complete. This can depend on the size of the pipe.

Benefits of CIPP

  • Allows for pipes to be rehabilitated without disturbing the surrounding neighborhoods and businesses.
  • Less expensive than replacing the pipe.
  • Allows for an increased sewer flow capacity.
  • The process has a 50-year design life.
  • Process is completed in one to three days.

How Will I Be Affected?

Residents may see activities related to the sewer relining for several weeks leading up to the actual lining. These activities include:

  • Assessment of flow conditions within the main sanitary sewer using remote controlled video cameras.
  • Cleaning and inspecting the main sanitary sewer prior and after the sewer lining process is completed.
  • Dye testing to confirm connections between buildings and sewers.

On the day of the work, we’ll turn off the water service to the residence between 8:30 a.m.-6:00 p.m. This is to prevent involuntary sewage backup into your home. Residents may also experience noise from the equipment, unpleasant odor from the liner and parking restrictions.

Any unused/dry drains that connect to the sanitary sewer system should be filled with water to prevent sewer gases from entering the residence. These drains include:

  • Floor drains. Most residential basements have one or more floor drains, usually near the water heater, washer/dryer and A/C unit.
  • Unused bath tubs, showers, sinks, etc. You may want to pour water in these fixtures because lack of use may have caused the drains to dry out over time.
  • Sump pump. Found in residential basements, sump pumps have a motor that turns on when the water table is above the foundation of the home. In some cases, older sump pumps are connected to the sanitary sewer system, therefore if your sump pump has not been running for a while, it is a good idea to pour water into the pit to allow the sump pump to run.

2016 Watermain Projects

– The City will be replacing a twelve-inch (12”) watermain on Ridgeview Drive, between Far Hill Road and Broadway Avenue.  This segment of pipe has experienced multiple breaks since its installation in 1971.  The City will also be completing a six-inch (6”) watermain loop on Eastman Lane.  This project is proposed to be awarded to a contractor in early May and completed by the end of June 2016.

Water Treatment Plant #2 Rehabilitation

– Magney Construction has been hired to upgrade many of the systems at the water treatment plant, located on West Lake Street. The work will be completed in June 2016.

Peavey Bridge

– The bridge over the Peavey Channel, on Ferndale Road West, was reconstructed in 2015. Several outstanding, smaller construction items remain, including concrete touch-up, curb and gutter, and paving on the east side of the bridge.  This work should be completed by the end of May 2015.
