MEMORANDUM
TO: Honorable Mayor and Members of the Common Council
FROM: Justin Gierach, Engineering Division Manager/City Engineer
DATE: April 9,2020
RE: Approve Amendment to Agreement for Flow Monitoring Collection Services
for 2020/ADS Environmental Services,Inc. (ADS) ($59,985)
BACKGROUND
An agreement for flow monitoring collection was awarded by the Common Council to ADS on
March 26, 2019.
The past seven years the City has utilized ADS to conduct flow monitoring services to collect
sanitary sewer flow data used to identify areas of high inflow and infiltration of clear water into
the sanitary sewer system. This data is utilized to calibrate and verify the sanitary collection
system model that was developed by Jacobs Engineering Group, Inc. (formerly CH2M Hill).
ANALYSIS
With a combination of the computer virus from earlier this year and the COVID-19 virus
sweeping the globe, bids for this work were not able to be sent out as usual. This work is time
sensitive as we need to collect data during the spring rains. Staff asked ADS to provide costs for
new locations throughout the City.
FISCAL IMPACT
Staff has reviewed the amendment and the proposed costs and has found the costs consistent
with the level of effort that will be expended in order to complete this project. The amount of this
contract amendment is $59,985. This will raise the total agreement amount to $131,983 (not to
exceed). Funds for this project are included in the 2020 Wastewater Utility Operating Budget.
