Commission forwards wastewater master plan after treatment‑plant cost increase to $259M

City engineer Vince Hoag presented the wastewater master plan and the related wastewater impact‑fee facility plan during the Sept. 8 meeting. Hoag said the city refined design to 60% for a treatment plant expansion and east‑side trunk line and that updated cost estimates had increased considerably.

Hoag said the plant expansion estimate rose "from 193,000,000 to 259,000,000," and that the project would increase treated‑water capacity from 2,400,000 gallons a day to 8,000,000 gallons per day. He added that the existing trunk line along Pony Express is near capacity and that a new east trunk line will be needed to serve additional growth on the north and east sides of the city.

There were no public comments during the public hearing. Following staff discussion, the commission moved to forward a positive recommendation to City Council on the wastewater master plan and associated IFFP; the motion passed 5–0.
