CITY OF HOPKINS
Memorandum
To: Honorable Mayor and Council Members
Mike Mornson, City Manager
From: Nate Stanley, City Engineer
Date: September 14, 2021
Subject: 2022 Trunk Water Main Rehabilitation Project
_____________________________________________________________________
PURPOSE
To present the results of the preliminary engineering report undertaken to investigate
rehabilitation of the City’s trunk water main system in the area of the Water Treatment
Plant.
INFORMATION
In 2016, staff had an evaluation completed of various critical segments of water main
around town and it was discovered that the trunk water main north of TH 7 had
experienced significant deterioration and had exceeded its expected service life. This
main is a critical line as it supplies water direct from the treatment plant to the
distribution network. Since the existing pavement over these water mains was largely in
good condition, a study focusing on trenchless rehabilitation methods was undertaken.
The preliminary engineering report has been completed and a presentation has been
prepared. Staff recommends advancing to final design and making the recommended
improvements in 2022.
FUTURE ACTION
Final design will be completed this winter and staff will bring final plans and
specifications back before council and ask for authorization to advertise for bids.
