The original cast iron water main within the project area was installed in 1895. It has suffered repeated breaks over the years and has exceeded its useful life. 

SPRWS crews along with Quam Construction Co. will replace the existing 6” cast iron water main with 8” HDPE pipe via a trenchless method called pipe bursting.

This work is being coordinated in advance of mill and overlay improvements planned to be completed by St. Paul Public Works in 2020.

Project Scope:

  • Replace 1,400 ft. – 6” water main

  • Replace valves and hydrants

  • Restore street pavement as needed

Project Updates


SPRWS crews will be potholing and excavating on the west side of St. Peter to locate utilities beginning the week of April 15 to about April 29.

Temporary Water Services Lines

Temporary water lines will be constructed above ground along the sidewalks to provide water service to customers currently fed by the St. Peter St. water main.

This work will continue into the week of April 22, with excavations being done in the sidewalk areas at various locations to tie into underground service lines.

Project Updates

  • Excavation continues between 7th Place and 7th Street in preparation for water main to be installed via pipe bursting the week of May 20.
  • Temporary water lines are currently being put up along the sidewalks on both sides of the street between 7th Street and 10th Street.
  • No parking will be allowed on both sides of the street between 7th St. and Exchange St. as of May 10.
    (No parking continues between 7
    th Place and 7th St.)
  • Traffic will be reduced to a single lane on St. Peter between 7th Street and 10th Street starting May 13 and excavation will begin for temporary water connections.
  • 7th Street will be reduced to a single lane in each direction towards the end of the week of May 22-24 with the crosswalk on the north side of 7th closed to pedestrians.

Project Updates

Water main installation is complete from 7th Place to 7th Street. During the week of May 28th crews will be doing final service connections, removing temporary water and restoring pavement.  

Once restoration of the pavement is complete, traffic will be opened to 2 lanes and parking allowed on both sides of the street south of 7th Street. This is anticipated to occur the week of June 3rd.

Crews will continue water main work north of 7th Street next week. Traffic going southbound on St. Peter will continue to be restricted to a single lane between 10th Street to 7th Street likely through the end of June.

Project Updates

Work at the intersection of 10th and St. Peter will require a closure of eastbound and westbound traffic on 10th Street tonight from 5 pm to midnight. St. Peter Street will remain open to traffic with a detour provided for 10th Street traffic.

New water main pipe will be pulled in tonight from 10th Street to 7th Street. Crews will begin reconnecting service connections next week and getting ready to flush and test the new main. We expect to be complete with this section of the project by July 4th after which point we will be continuing north from 10th Street to 11th Street.

Project Updates

Restoration of the pit on the north side of 7th Street is underway. The 7th Street crosswalk is expected to be reopened by Saturday, June 22nd.

On Monday, June 24th, the eastbound lanes of 10th street from Dorothy Day Place to Wabasha will be closed for up to 5 days in order to allow for valves to be installed in front of the St. Joe's main entrance and on the west side of the 10th/St. Peter intersection. Normal traffic lanes will be restored by the end of next week.

We expect to be complete with work between 7th St. and 10th St. by July 4th. Work will continue from 10th to 11th.
