Santaquin staff warn sewer, reclaimed-water storage will need near-term investment as growth continues

City officials told the Santaquin City Council at a work session April 15 that the city’s wastewater treatment plant and reclaimed-water storage are approaching capacity and will require capital investment and financing to serve already-committed development.

The presentation laid out the most immediate numbers: Santaquin currently has about 5,500 equivalent residential connections (ERCs or “doors”), a wastewater reclamation facility (WRF) pinch point at about 8,900 doors, and roughly 10,000–10,400 doors possible under current land use and vested entitlements. Staff said roughly 2,300 additional doors are imminent because of development agreements and approved plans.

Staff recommended planning now because a formal moratorium on service would be legally limited to six months and design/construction of a new WRF typically takes years.

Why this matters: Council members asked how quickly capacity limits could be reached. Staff estimated current growth at roughly 225–250…
