City plans phased water- and sewer-plant repairs, CIPP lining and a fourth water tower as growth pushes capacity needs
Summary
Public Utilities Director Lake Jordan outlined planned plant maintenance (process floor coating, pump and belt-replacement work), phased primary-settling-tank repairs, cast-in-place pipe (CIPP) lining projects, and long-range planning for a fourth elevated water tower as average daily flow approaches 4 million gallons.
Public Utilities Director Lake Jordan told the committee several water- and sewer-system projects are prioritized in the CIP to maintain capacity and reliability. He said process floor coating at the water plant, deferred from earlier value engineering, needs repair in 2026 because cracking allows water intrusion to the basement. Jordan also described scheduled staggered pump replacements and an upcoming gravity-belt thickener replacement.
On the sewer side, Jordan explained the primary settling tank chains and scrapers (installed 2007) have reached end-of-life; the CIP phases repairs with two tanks per year and contractors have been solicited. He described cast-in-place pipe (CIPP) as a lining approach for failing pipes and flagged large capacity projects such as the South Industrial Loop and the Northeast Olentangy interceptor, which are in design/feasibility phases. Jordan said daily average flow is approaching 4,000,000 gallons, prompting planning for a fourth elevated water tower to add storage and pressure capacity.
