Project Details

The original water main on Thomas Avenue and Edmund Avenue is unlined cast iron installed between 1906 and 1910. As unlined pipes age, mineral deposits collect inside the pipes which can decrease water volume and hinder flow for fighting fires. Such deposits can also affect water quality. Water main cleaning and lining is a method of pipe rehabilitation that is used when water mains are structurally sound but suffer from such corrosion and mineral deposits. The pipes will be cleaned with a tool that scrapes off internal mineral deposits. Then the pipe will be sprayed with a thin layer of cement mortar. This will increase flow capacity in the water main and provide a protective barrier against internal corrosion.

SPRWS will be hiring a contractor to clean and line the existing 6" cast iron water main on Thomas and Edmund. SPRWS crews will be performing all excavation and restoration. The scope of the project is as follows:

  • Clean and line approximately 2,500 feet of 6" cast iron water main on Thomas Avenue
  • Clean and line approximately 2,500 feet of 6" cast iron water main on Edmund Avenue
  • Replace necessary valves and hydrants in the project area
  • Repair and restore any areas disturbed by project activities

Lead Service Replacement
Lead service lines were primarily installed in the City of St. Paul from late 1880’s to the late 1920’s. For 25 years Saint Paul Regional Water Services (SPRWS) has been replacing lead water service lines within the street right-of-way to reduce the possibility of lead exposure.

Private Lead Service Line Replacements: Customers in this project area who have a private lead service line are eligible to have it replaced at no cost as part of the new Lead Free SPRWS program. You should have received a letter with instructions on next steps if you qualify. To learn more visit our lead page.

In anticipation of an upcoming main replacement project, SPRWS will be replacing all existing lead services within the street right-of way with copper pipe. This project is completely funded by SPRWS with no charge to the property owner.
