On August 3 at 2:11 p.m., we received notice that a contractor performing work for the
Minnesota Department of Transportation had drilled into our 24-inch diameter water
main along Highway 169justsouthof School Street.Staff from every department at
ERMU began the challenging task of stopping the water leak while keeping the rest of
the water systemin Elk Riverpressurized. Due to the location of the leak, it required
shutting off thewater supply from Freeport Water Tower; at this point we had two
water towers off line as the Gary Street Water Tower was already out of service due to
scheduledmaintenance.Brenteson Excavation washired to perform the excavation and
repair work of the damaged water main. ERMU staff worked through the night until the
morning of August 4when the pipe repair was complete,and the water was turned back
on. Photosare attached.
Staff worked with Elfering and Associates to investigateoptions for running watermain
rd
to Windsor Park 3 Addition. According to our water modelif a twelve-inchwater main
was installed alongCounty Road 1 to County Road 33 and then over to that
development, they would have approximately50 psi of water pressure. Elfering and
Associates also proposed a water main on Meadowvale Road to create a water main

loop that would increase water flow and improve water quality to that northern area, it
would not increase water pressure. The estimated costof directionally drilling 12,500
feet oftwelve-inch watermain, adding fire hydrants, valves, traffic control, mobilization,
and restoration would be approximately$2,000,000.Thiscost does not include the
water main loop along Meadowvale Road. Attached is a drawing of the proposed water
mains.
During a scheduled water main shutdown for the rehabilitation project on Proctor
th
Avenue, two water main valves located in the intersection of 6Street and Proctor
Avenue began to leak after being operated.Utilizing theircontractorfor the project,we
worked with the County to have thevalves excavated and repaired. The estimated cost
for the repairs is $12,100.
The final coats of paint are being applied to Gary Street Water Tower’s interior, the
project should be complete on or about August 14.
rd
Avenue, which was identified during our leak detection
The water main leak on 183
survey, has been repaired.
Sprint has decided to reinstall their equipment onto Auburn Street Water Tower since
all three lease agreements withERMU have been renewed for another 5-yearterm.
The water operators have continued to fix fire hydrants thatwere identified as needing
repair during flushing and our leak detection survey. They have also started exercising
and repairing distribution system gate valves as part of the annual gate valve exercising
program.
