Water Rehabilitation Iron deposits on valve pipe

Since August 2004, water line rehabilitation projects have occurred along pipelines throughout Greensboro as a way to continuously improve our distribution system.

Water rehabilitation is done on cast iron pipes that were installed before the mid-1950s. This particular type of piping does not contain the protective cement mortar lining that is present in new pipes today. Because there is no protective lining, damage occurs as the water begins to flow and excessive deposits of iron settle along the lining of the pipe. This damage is called "tuberculation." The inside of the pipe is cleaned to remove accumulated materials and then lined to prevent further corrosion. Once the pipe is cleaned, water flows more freely. Inside pipe after water rehabilitation project

The current project area (pdf) consists of 9.76 miles of pipline. Due to the enormous size of the project, work will occur in designated areas of the city at different  times. Specific project area maps are linked as PDFs below:

  • Area 1 project locations include: Walker Ave.

  • Area 2 project locations include: Colonial Ave., Independence Rd., Liberty Dr., Lafayette Ave., Brookside Dr., Kirkpatrick Pl., Princess Ann St., Hawthorne St., Dellwood Dr., Fernwood Dr., Rosecrest Dr., Fairfield Ave. 

  • Area 3 project locations include: Kirby Dr., Forestdale Dr., Wedgedale Ave., Starmount Dr., Madison Ave., Beverly Pl., W. Avondale Dr., E. Avondale Dr., Homewood Ave., Edgewater Dr., Dogwood Dr., W. Brentwood Rd., E. Brentwood Rd.

During the project, residents and businesses along the routes are provided with a temporary water supply. Connections are made to the service line from alternate pipelines laid alongside the curbs on each side of the street. Typically, projects last about two months, however the connection to a temporary water line is only needed for four to six weeks. 

The City tries to minimize inconveniences to our customers during these projects. If you have questions about the Water Rehabilitation project, see the list of frequently asked questions or contact the Engineering division of the Water Resources Department.
