Boise Puts Southeast Water Recycling Facility on Hold as Construction Costs Climb

Interstate highway

The City of Boise has indefinitely paused plans for a first-of-its-kind recycled water treatment facility in southeast Boise, citing rising construction and labor costs that threatened to strain utility budgets and push up rates for residents. The announcement came Tuesday, June 2, halting a project that had been years in development and backed by a voter-approved bond.

What Was Planned for the Southeast Boise Site

The facility was slated for a 76-acre parcel near the WinCo Distribution Center in southeast Boise. Once operational, the plant would have treated up to 6 million gallons of industrial wastewater per day, with the resulting recycled water available for use by area businesses or injected directly into the city’s aquifer — the underground water source that supplies roughly 70% of Boise’s drinking water.

The project originated from a 2021 utility plan approved by city leaders and was supported by a $570 million voter-approved bond dedicated to water infrastructure upgrades across the city. Construction had not yet begun, with a groundbreaking originally expected in 2027 and full operations anticipated in the early 2030s.

Rising Costs Prompt the Indefinite Pause

City officials said the decision to pause came down to a significant and broad-based increase in construction and labor costs, both locally in the Treasure Valley and across the country. With no groundbreaking yet taken place, the city determined this was the right moment to reassess rather than proceed into a project that could place undue financial pressure on utility ratepayers.

Boise Public Works Director Steve Burgos acknowledged the difficulty of the decision. “Pausing this recycled water project is disappointing for our team and our community, who continue to show their support for protecting our local water resources,” Burgos said.

City officials stressed that recycled water remains a component of Boise’s long-term water strategy and that staff are now reviewing alternative approaches to meet the city’s water resilience goals.

Impact on Ada County Residents and Boise’s Water Future

Boise currently treats approximately 30 million gallons of wastewater each day at existing facilities, with that treated water discharged into the Boise River. The southeast facility was intended to divert a portion of that flow into productive reuse — both easing demand on the aquifer and reducing river discharge volumes.

With the aquifer supplying the overwhelming majority of the city’s drinking water, long-range planning around water supply is a significant concern for Ada County’s growing population. Boise and the broader Treasure Valley have seen rapid growth in recent years, adding pressure to both water supply and infrastructure planning.

For homeowners and businesses connected to Boise’s water utility, the pause offers some near-term relief from potential rate increases that a costly construction project might have triggered. However, the deferral also means the city’s long-term water resilience strategy will need to adapt.

For context on other infrastructure developments affecting Ada County residents, the Ada County Highway District recently adopted new rules to fine traffic-control firms directly, with changes taking effect June 27 — another sign that local agencies are navigating rising costs and accountability pressures across the board.

What Comes Next

The City of Boise has not set a timeline for revisiting the recycled water facility. Officials indicated they will evaluate alternative strategies to achieve the same water resilience outcomes outlined in the original 2021 utility plan. Residents interested in the city’s long-term water and infrastructure planning can monitor updates through the City of Boise’s Public Works department. No formal public meetings on the revised water strategy have been announced as of this report.
