Council approves change order and advances wastewater reuse planning work
Summary
Council approved a small credit and deadline extension for the WWTP disc-filter installation and directed staff to advance a planning-level effluent reuse study; due to a dissent the planning-item will come back as an action item next week for separate votes.
Council reviewed two related wastewater items: a change order for Action Contracting on the wastewater treatment plant (WWTP) disc-filter installation and a separate planning-level change order to begin a wastewater effluent reuse study (Hanson & Luce) and related Water Master Plan modeling.
Jonathan Stathis (Engineering) said the Action Contracting change order reconciles interest on a prepayment (a credit of roughly $642) and extends the contract completion date because the large disc-filter units arrived later than expected. Philip Green of Action Contracting explained equipment and scheduling delays and said commissioning was deferred after plant staff recommended delaying start-up to avoid clogging the new filters with high total suspended solids. "We didn't get them until November 2…we had 8 to 12 weeks to order the spools," Green said, describing logistics and the need for a realistic commissioning window.
Council approved that change order and placed it on consent.
On the related reuse study, Jonathan described a planning-level analysis to identify pipeline routes, booster stations and high-level cost estimates for distributing treated effluent to parks, SUU and other outdoor uses. Some council members expressed concern about timing and cost—Councilmember Schmidt said the city lacks funding and that large distribution into town may not be feasible now—while others said the engineering study is necessary to support grant applications and future bonding discussions. The council agreed to advance the study but, because of a recorded 'nay' and procedural rules, directed staff to present the full combined item on action next week so council can vote on the two parts together or separately.
Ending: The disc-filter change order will proceed; staff will refine the reuse study scope and bring both parts to next week's action agenda where council will take final votes.
