Home My WebLink AboutPurchase Approval - S4 Water Sales & Service LLC - Filter Anthracite $24,779.15 (3) To: Luke Stowe, City Manager Edgar Cano, Public Works Director From: Darrell A. King, Water Production Bureau Chief Subject: Filter Anthracite Purchase Date: July 6, 2026 Recommended Action: Staff recommend the City Manager approve the purchase of filter anthracite from S4 Water Sales and Service, LLC. (160 Vanderbilt Court, Bowling Green, KY., 42103) in the amount of $24,779.15. Funding Source: Funding in the amount of $24,665.75 will be from the Water Fund account number 510.40.4220.65070, which has a FY 2025 budget allocation of $94,500.00. This account has a year-to-date balance of $55,345.62. Background: The Evanston Water Treatment Plant filtration system consists of a total of 24 filters with a peak rated filtration capacity of 108 million gallons per day (mgd). Maintaining water filtration plants require proper preventative maintenance which in turn can prolong filter operation, enhance performance, and ensure effluent goals and regulatory compliance requirements are achieved. Anthracite is a component of the filter media that removes particulate matter from the water during the filtration process. The filtration process largely depends on the filter media, and media performance depends primarily on the media’s physical condition; backwash effectiveness; and maintaining the correct media depth and retention. Normal filter backwash operations eventually wear and smooth anthracite particles as well as causing the anthracite to be broken into small pieces that are lost during the process. In addition, mud ball removal occurs as part of our filter preventative maintenance program. Anthracite is also lost during this operation and must be replaced.
