CITY COUNCIL AGENDA ITEM
ACTION REQUESTED:
title
Approve the award of Change Order #1 to Option Year One of Contract 20-002, Leak Survey, to ADS Environmental Services for an amount not to exceed $169,048 for a one-year term
body
DEPARTMENT: Water Utilities
SUBMITTED BY: Darrell Blenniss, Director
BACKGROUND:
The Water Utilities began conducting annual leak surveys in 2007 and has experienced great success with finding undetected leaks. In 2018, the Water Utilities went from annual inspections of the entire water distribution system to semi-annual surveys. The most recent surveys conducted in 2021 resulted in the identification and repair of:
• 48 leaks with a total estimated leakage of 376,000 gallons per day in the spring/summer survey
• 74 leaks with a total estimated leakage of 510,000 gallons per day in the fall/winter survey
DISCUSSION:
In December 2019, the Water Utilities issued Bid 20-002, 2020 Distribution System Leak Detection Survey Program, to obtain a vendor to perform water distribution system leak detection and correlation for approximately 748 miles (3,870,874 linear feet) of public water distribution mains. The survey includes appurtenant valves, hydrants, fire lines, and service lines as required to detect and correlate leaks.
ADS Environmental Services has done an outstanding job with the leak surveys and final reports. All work was performed in a timely manner with zero concerns.
The term of the first option year is January 1, 2023 to December 31, 2023, with one, one-year option remaining on the agreement.
ADS Environmental Services has asked for a 3% increase, due to increased fuel cost. Staff recommends awarding the first option year to ADS Environmental Service.
FISCAL IMPACT:
CIP#: N/A
Distribution Leak surveys are expensed to the Operational services account listed below. A total of $175,000 has been submitted for this service as part of the 2023 budget which is currently in review. Pending Council approval, the requested award of $169,048 is expected to be within budget.
