REPORT TO COUNCIL
SUBJECT
Title
Action on Ratification of an Emergency Sole Source Purchase Order to Pump Repair Services Company for the Purchase and Installation of a Replacement Pump and Motor for the City's Groundwater Well 10 in an Amount Not to Exceed $362,675
Report
BACKGROUND
The City's groundwater wells provide approximately 60 percent of the City's potable water supply. One of those wells, Well 10, located at 3640 Forest Avenue, was constructed in 1957 and is one of the City's active groundwater production wells.

Due to the age of Well 10 and its continued role as an active potable water supply asset, timely repair and replacement of critical well components is necessary to maintain production capacity, regulatory compliance, and water system reliability. When a groundwater production well is removed from service for an extended period, the City may face regulatory, operational, and cost impacts associated with returning the well to active service.
