Item No. 10 26 9
Date: 07/26/10
Item/Subject: ORDER, Awarding Contract for Flow Monitors for Combined Sewer
Overflows
Responsible Department: Waste Water Treatment Plant
Commentary:
As part of the plant's Long Term Control Plan (LTCP) for combined sewer overflows (CSO) the City is
required to install monitoring equipment at CSO points that will remain active. The LTCP requires
that the City be able to measure the frequency, duration and volume of combined sewage
discharged during wet weather. There are currently eight active CSO points within the City, only
three of which are monitored.
The attached order would award a contract to ADS Environmental Services to install equipment in
the remaining five active CSO points. The five remaining locations are difficult applications that
require expertise to install and calibrate the instrumentation. ADS is the only company with flow
meters that have the flexibility of integrated wireless modems and/or 4:20 Amp output to SCADA.
This versatility is critical to this project as bother cellular communication and radio telemetry will be
utilized. Flow meters manufactured by ADS are the only USEPA Environmental Technology Verified
flow monitoring equipment for wastewater collection systems. ADS meters are also the only brand
with Monitor Level Intelligence which improves accuracy and allows the meter to operation in a wide
range of flow conditions.
On July 19, 2010 the Finance Committee reviewed and approved staff recommendation to award the
sole source contract to ADS Environmental Services in the amount of $94,250.
The contract award recommendation must be reviewed approved by the City Council as it is over
$50,000.

From: Brad Moore
Re: Sole source purchase of flow monitors for Combined Sewer Overflows (CSO)
As you may be aware, part of the Long Term Control Plan (LTCP) for Bangor's CSO's
requires we install flow metering equipment at CSO points that will remain active. The
LTCP requires that the City be able to measure the frequency, duration and volume of
combined sewage discharged during wet weather. At this time we have eight remaining
CSO's, five require specialized equipment to measure discharges. Included with this
memo is a proposal from ADS Environmental Services (ADS) for the five remaining
locations. As you can imagine, these locations are difficult applications that require
expertise to install and calibrate the instrumentation.
ADS is the only company with flow meters that have the flexibility of integrated wireless
modems and or 4:20 mAmp output to SCADA. This versatility is critical to this project as
both cellular communication and radio telemetry will be utilized.
Flow meters manufactured by ADS are the only USEPA Environmental Technology
Verified (ETV) flow monitoring technology for wastewater collection systems. ADS
meters are also the only brand with Monitor Level Intelligence (MLI) which improves
accuracy and allows the meter to operate in a wide range of flow conditions.
Funding for this purchase will come from a State Revolving Loan Fund. John True, CSO
Coordinator MEDEP, has agreed to allow sole source purchase of this equipment. I have
included a memo sent to John True justifying sole source purchase and his affirmative
reply.
Please contact me if you have any further questions or concerns.
