CITY COUNCIL AGENDA REPORT
MEETING DATE: APRIL 4, 2011
AGENDA #: 9A
PREPARED BY: STEVE ALBRECHT, PUBLIC WORKS DIRECTOR
PRESENTER: STEVE ALBRECHT
AGENDA ITEM: CONSIDER APPROVAL OF A REPORT REGARDING STATUS OF
CURRENT WATER SYSTEM PROJECTS
DISCUSSION: Introduction
The purpose of this agenda is to update the City Council on the status of
current water system projects.
Hi story
Over the past several months the City has undertaken the following Water
System Projects /Studies:
1) Water Meter and Automatic Meter Reading System (AMRS)
Replacement Project
2) City of Prior Lake and Shakopee Mdewakanton Sioux Community Joint
Northern Water System Study
3) City of Prior Lake Water Supply Options Report
4) Water and Sewer Rate Plan
Current Circumstances
1) Water Meter and AMRS Replacement Project
Staff delayed issuing the Request for Qualifications to AMRS vendors until
additional information from the City's existing provider Aclara could be
obtained. As part of that process the City now has the ability to read the
battery strengths of the existing individual AMRS units which should allow
the City to extend the replacement program timeframe. The ability to
monitor battery strengths should allow the City to get up to 15 years of life
out of the 6,000 units installed in 2002/2003 and the subsequent units
installed prior to 2008. The units installed after 2008 should last 15 or more
years based on battery technology improvements implemented after that
date.
The estimated replacement schedule is as follows:
Year

2020

*Includes meter replacement
* *Includes approximately 400 meter replacements
The present value of the replacement over a ten -year period is estimated to
be $1.8 - $1.9 million. This amount does not include any additional meter
replacement beyond the 1,888 meters identified in years 2011 -2014.
Staff proposes the following amended project timeline:
April 2011: Solicit Requests for Qualifications from AMRS Vendors
May /June 2011: City Council Accepts RFQ's Authorizes advertisement
for bids for AMRS Replacement Program
July 2011: City Council Accepts Bids and Approves Contract
September 2011: AMRS Replacement Program Begins
2) Joint Northern Water System Study
Last fall City staff presented a Water Supply Options Report that identified
several options to meet the City's current "firm capacity" and emergency
water supply needs along with future demand needs. The options
discussed included construction of City Well No. 10, an upgraded
interconnection with Savage and a Joint Northern Water System with the
SMSC.
Currently the City of Prior Lake and SMSC water models are being
updated. The City of Prior Lakes water system was last modeled in 2003.
Since that date, substantial improvements have been made to the system
requiring the model be updated. Technology (software) and model
advancements have also advanced making the 2003 model obsolete and
less accurate. The process of updating the model is not anticipated to be
completed until May.
Once the City and SMSC models are updated the joint system model can
be developed and run. Upon completion of the joint system model the
study will be completed identifying the pros /cons of a joint system and the
potential costs. The study is anticipated to be completed by July 2011.
3) Water Supply Options Report
Once item 2 is completed, City staff will prepare a final report and
recommendation on the best emergency and long -term demand options for
the City's water system. This report will be presented in August in
conjunction with final CIP and preliminary budget discussions.
4) Water and Sewer Rate Plan
A preliminary water and sewer rate plan will be presented as part of the
long range Water and Sewer System plans presented in the Capital
Improvement Program in July /August. The plan will be subject to the final
recommendations of the Water Supply Options Report.
Conclusion
The City Council should provide comment and direction on the Water
System projects and proposed schedule.
ISSUES: Public Works Director transition and City staff workload may impact the
proposed schedule.
