CONSIDER APPROVAL OF A RESOLUTION AUTHORIZING THE
PURCHASE OF OMNI-SITE TELEMETRY UNITS FOR THE LIFT STATION
RESTORATION PROJECT
Histor~
The proper function of a sanitary sewer system is vital to protect public health, property
and water ways in surrounding areas. New regulations from the Environmental
Protection Agency (EPA) will be implemented in the next few years to help in
prevention of sanitary sewer overflows. All collection systems will have a National
Pollution Discharge Elimination System (NPDES) number in addition to a Capacity
Management Operation and Maintenance (CMOM) system in place. What this means
is the maintenance or improvements completed by staff or outside vendors is now
documented and filed is required to be mailed to the EPA.
Being responsible and proactive to prevent potential sanitary overflows and backups
from lift station failures, staff investigated the possibility of using telemetry on the
City's sanitary lift stations. While looking into the possibility of adding 34 lift stations
to the City's current Supervisory Control and Data Acquisition (SCADA) system, the
costs of purchasing the monitoring equipment along with installation was very high.
Our estimate provided was over $19,000 per lift station site. Further investigation was
completed on using wireless phone equipment units which gather lift station
information through the internet and make it available to staff. The SCADA system
also calls out maintenance personnel rather than waiting on residence calls for
notification of alarm sounds or alarm lights.
Staff found two quality companies. The first being Mission Control through Quality
Flow of New Prague; second being Crystal Ball, Omni-Site through Electric Pump of
Bloomington. Both companies provided very similar equipment and service. Initial
equipment and monthly service costs were considerably higher with Mission Control as
compared to Crystal Ball, Omni-Site.
Current Circumstances
Over the past few years staff has chosen to use the Crystal Ball, Omni-Site SCADA
system. A number of these units have been installed in existing lift stations and
included in all cabinets rehabilitated as part of the 2003-2004 lift station rehabilitation
project. These units are also required by developers to install as part of new lift station
installations per the City's Lift Station Standardization Policy. These units allow staff
to monitor twelve points for potential problems.

REVIEWED BY:
The points monitored are listed below:
· Wet well high level
· Wet well low level
· Power failure/phase failure
· Pump one run time, seal fail
· Pump two runtime, seal fail
· Control panel low temperature
· Control panel high temperature
· Engine generator running
· Engine generator alarm
· Control backup power
Staff is very satisfied with these omni units in both data acquisition and in alarm
notification. We have seen a significant improvement in response time to lift station
alarms.
Budget Impact
As part of the 2005-2009 Capital Improvement Budget, staff recognized the need for
the expenditure of approximately $25,000 for telemetry units for lift stations. This
amount is being funded through the Sewer Operating Fund.
Following through with the City's lift station standardization, staff would recommend
utilizing the current vendor Crystal Ball, Omni-Site, through Electric Pump. There are
no new equipment price increases from last year. Quotes for the units are as follows:
Units Cost per Unit Total Cost Tax Total Cost
Crystal Ball 10 $2,000 $20,000 $1,300 $21,300
Omni Site
Mission Control 10 $2,500 $25,000 $1,625 $26,625
The Mission Control system costs $24 per site per month in operating costs. The
monthly charge for the Omni-Site unit is $22 per site per month.
These are brought to the City Council for approval since it is the total is over $20,000
and derived from the Utility Fund.
The alternatives are as follows:
1. Approve the resolution authorizing the purchase of ten Crystal Ball, Omni-Site
telemetry units from Electric Pump of Bloomington, Minnesota for a cost not to
exceed $21,300.
2. Table this agenda item for a specific reason.
3. Deny this agenda item for a specific reason and provide staff with direction.
Staff recommends alternative number 1.
