CITY COUNCIL AGENDA REPORT
MEETING DATE: JANUARY 16, 2018
AGENDA #: 9A
PREPARED BY: JASON WEDEL, PUBLIC WORKS DIRECTOR/CITY ENGINEER
PRESENTED BY: JASON WEDEL
AGENDA ITEM: CONSIDER APPROVAL OF A RESOLUTION UPDATING THE PRIOR
LAKES PUBLIC WORKS OPERATIONS MANUAL POLICY ON FROZEN
WATER SERVICE THAWING
DISCUSSION: Introduction
The purpose of this agenda item is to consider updating the City of Prior
Lakes Operations Manual Policy - Frozen Water Service Thawing
History
There are roughly 9,000 water service connections within the City of Prior
Lake. Typically, these service connections are buried below the average
frost table depth to ensure they do not freeze. If the water service is above
the average frost table or there is an unusually harsh winter driving the
frost table deeper, some service lines become susceptible to freezing.
When this happens the City receives requests for assistance in thawing
service lines.
The service line is the responsibility of the property owner from the meter
inside the house to the curb stop, typically located at the right-of-way
(ROW) line. The curb stop and the remaining service line to the watermain
in the street are the responsibility of the City. If the service line freezes, it
can be difficult to determine where the issue has occurred and whom is
responsible. Therefore the City Council adopted the Frozen Water Service
Thawing Policy on November 28, 2016.
Current Circumstances
Recently, City Staff was informed of incidents in neighboring cities of
property owners using electrical welding methods to thaw services that
have damaged other properties during this process. Due to improper
grounding, electrical components can short circuit and fires in neighboring
structures are possible.
In addition, the City standards have changed for water service pipe
materials over the past couple of years. Previously water services were
constructed using copper but now that has changed to polyethylene
(plastic). Any use of electrical methods to thaw a polyethylene water
service could result in melting and damage to the service resulting in leaks.

Conclusion
It is recommended that the Council approve the revised Water Service
Thawing policy to clarify the use of electrical welding equipment to thaw
service lines is not permitted in the City of Prior Lake.
This policy change is recommended as part of the city’s risk management
program. The city is insured by the League of Minnesota Cities Insurance
Trust. The trust seeks to provide appropriate coverages but also to limit
exposure.
When the city does work which damages private property there is an
expectation that we will bear some of the cost. The city should be
responsible for public infrastructure but not private infrastructure.
There are also properties in the community where frozen pipes tend to
occur year after year. The revision in this policy encourages property
owners to take corrective action rather than rely on the city year after year.
The revised policy could actually reduce city liability exposure which in
turn could mitigate against increases in our insurance premiums. It may
also reduce the amount of time city staff spends on addressing private
rather than public property issues.
ALTERNATIVES: 1.Approve the resolution updating the Water Service Thawing as
presented or as amended by the city council.
2.Table the resolution with direction to staff.

VII. WATER SERVICE THAWING POLICY
Adopted by City Council November 28, 2016
Revised by City Council January 16, 2018
SUMMARY/PURPOSE
There are roughly 9,000 water service connections within the City of Prior Lake. Typically, these service
connections are buried below the average frost table depth to ensure they do not freeze. If the water
service is above the average frost table or we experience an unusually harsh winter driving the frost
table deeper, some service lines become susceptible to freezing. When this happens the City receives
requests for assistance in thawing service lines. The City has created this policy to define how the city
will respond to these requests.
POLICY
The service line is the responsibility of the property owner from the meter to the curb stop, typically
located at the right-of-way (ROW) line. The curb stop and remaining service line to the watermain in the
street are the responsibility of the City. If the service line freezes, it is difficult to determine where the
issue has occurred and whom is responsible.
The City has historically worked with property owners to address frozen service lines responding to 4-5
requests per year. However, during harsher winters we have experienced over 50 requests. This policy
and these procedures were developed to standardize the practice of thawing service lines to the best of
our ability while remaining cognizant of our limited resources and also reducing our liability when
entering into private properties.
a. The water service lateral from the curb stop to the meter is the responsibility of the property
owner.
b. The City will assist property owners by offering, at no charge, to thaw the service if it can be
accomplished without digging and if it is the first occurrence of the season for the property. A fee
will be charged for subsequent thawing services within a single season (November-March), which
can be found on the City’s fee schedule.
c. The City will attempt to thaw the service up to four (4) hours. If not successful, staff will re-
evaluate availability of resources at that time.
d. The property owner must sign a Right of Entry and Release of Liability before any work is
completed.
e. The City will not assist with any frozen water pipes on the house side of the meter.
f. The City has the right to refuse to enter a residence due to health and/or safety concerns
g. The City of Prior Lake does not guarantee a frozen water service can be thawed with City
resources.
h. The City reserves the right to deviate from this policy at any time if deemed to be in the best
interests of the City and its residents based on safety, political and economic considerations. Any
deviation and the reason for the deviation shall be documented in writing.
