CITY COUNCIL AGENDA REPORT
MEETING DATE: JUNE 4, 2017
AGENDA #: 8A
PREPARED BY: JASON WEDEL, PUBLIC WORKS DIRECTOR/CITY ENGINEER
PRESENTED BY: JASON WEDEL
AGENDA ITEM: CONSIDER APPROVAL OF A RESOLUTION ACCEPTING THE REVISED
PROPOSAL AND AUTHORIZING THE MAYOR AND CITY MANAGER TO
EXECUTE THE CITY’S STANDARDIZED CONSTRUCTION CONSTRACT FOR
THE 2018 AMRS REPLACEMENT PROJECT
DISCUSSION: Introduction
The City’s existing Automatic Meter Reading System (AMRS) was installed in
2002. The life expectancy of the Meter Transmitter Units (MTUs) within that
system is 20 years. The City is experiencing many of these MTU batteries already
expiring, which is making the collection of data for water billing purposes difficult.
It is therefore necessary to move forward with a full city-wide replacement.
The City included funds in the 2018 budget for this work. City staff sent out
Requests for Proposals (RFP’s) to three different vendors that provide these types
of improvements. The City Council selected Ferguson as the preferred vendor at
the May 7, 2018 City Council meeting and directed staff to negotiate with
Ferguson on the final contract amount and bring the contract back for
consideration of approval and authorization to proceed with the work at a future
meeting.
History
The City of Prior Lake’s water meter MTUs are reaching the end of their useful
lives. In 2002 the City installed an AMRS system consisting of MTUs, and
centralized data collecting units (DCUs). Readings collected by the meter registers
are transmitted to the central database once per day through a fixed radio system.
Prior to the AMRS, City staff would travel to each billing address once every two
months to collect meter reading data. This would take four staff members an
entire week to complete.
The current AMRS collects meter reading data multiple times every day.
However, there are meters that are not currently detected. The City has 14 DCUs
spread throughout the City that read the signals coming from the MTUs at each
billing address. Unfortunately, some locations remain undetectable to our DCUs.
The options for picking up these locations is adding more DCUs or having an
alternative method for obtaining readings from those locations such as a drive-by
detection unit. Due to the scattered nature of our missing meter reads, staff would
prefer a drive-by option. Unfortunately, our current Aclara system does not offer a
drive-by option.
The City has had a long history of issues with the current Aclara AMRS. When the
City reports a problem to the company, City staff must spend many hours of labor
and weeks or months of support requests before Aclara will acknowledge and
resolve the problem. In some instances, the problems are as simple as updating a
script or data library, but in other cases the source of the error has been a
complete hardware design failure. The significant investment in the AMRS
infrastructure makes it difficult for the City to cut its ties with Aclara, but these
failures have cost the City a substantial amount of money in lost staff productivity.
With the increasing number of existing MTUs failing every day it was necessary to
initiate the proposal process for their replacement this year. Delaying their
replacement would put the City in a position where we cannot keep up with daily
MTU replacements, which results in meters that go unread requiring Utility Billing
to make estimates on the amount of water used by those accounts.
Current Circumstances
The City received three proposals. The proposers included the City’s current
provider Aclara as well as Winwater and Ferguson. The City Council selected
Ferguson based on several factors including overall cost for MTU and water meter
replacement, the company being local, and they were the only provider that
offered a drive-by option for meter reading.
The total proposed cost for both MTU and water meter replacement was as
follows:
Ferguson $2,079,079.22
Aclara $2,834,885.00
Winwater $2,699,520.38
Ferguson was significantly less expensive than the other two providers when
including water meter replacement due primarily to the fact that they do the water
meter replacement with their own staff and the other two providers were proposing
to use subcontractors for that work.
The City’s budget for the AMRS project is $1,700,000. Therefore, the City Council
directed staff to work with Ferguson to negotiate a final contract amount that is
consistent with the allocated funding.
ISSUES: Staff recommended that the City Council include the water meter replacement
alternative along with the MTU replacement. There is an additional cost for doing
this; however, there are several benefits for doing both at the same time. First,
replacing the older water meters will result in more accurate water meter readings
which will provide more revenue to the City due to older meters under reporting
water usage. Second, replacing the water meters now will allow us to only
inconvenience our residents once. If we only replace the MTUs now we will be
back in approximately 5 years replacing the water meters. Each replacement
requires making appointments and having residents at home to allow us access to
their property to make the changes. Third, the benefit for City staff will be having
one consistent water system throughout the City. It will therefore be much more
efficient to maintain, because we will only have to stock one model of parts and we
only need to train our staff on how to service one type of product. Finally, it is
more cost effective to replace the MTUs and the water meters at the same time.
FINANCIAL
IMPACT:
As stated above, the original proposal from Ferguson for both MTU and water
meter replacement was $2,079,079.22. Staff worked with Ferguson to take a
harder look at the number of DCUs that would be needed to obtain the meter
readings as well as the actual number of water meters that would need to be
replaced. The result was that we were able to reduce the number of DCU’s from
20 to 13 and we were able to reduce the number of water meters being replaced
by approximately 2,200.
The reduction in DCUs is based on a revised propagation study. Once the system
is installed we will know if the study was accurate. There is a possibility that we
might need to add one or two more DCUs. The cost for a DCU is approximately
$20,000. The reduction in water meters was possible because Ferguson has
proposed using Neptune water meters. The City began using Neptune water
meters several years ago, so there are already approximately 2,200 Neptune
water meters in place that will not need to be replaced.
The reduction in DCUs and water meters resulted in a revised proposal cost of
$1,476,324.07. The budget for this work is $1,700,000 so the current proposal is
$223,675.93 below budget.
In addition to being below budget, the City will have an ongoing annual savings
due to the current budgets including $190,000 for water meter replacements.
Once this work is completed that annual expense will be significantly reduced.
ALTERNATIVES: 1. Approve a Resolution accepting Ferguson’s revised proposal and authorize
the Mayor and City Manager to execute the City’s Standardized
Construction Contract for the 2018 AMRS Replacement Project.
2. Deny this item for a specific reason and provide staff with direction.
3. Table this item until some date in the future.
