DEQ seeks comment on draft reuse permit for city of Kuna 

Accepting comments from April 9, 2024, through May 9, 2024. 

The Idaho Department of Environmental Quality (DEQ) is seeking comment on a draft reuse permit for the city of Kuna. 

The city is proposing to construct, own, and operate a new Class 1 municipal wastewater treatment facility that will receive domestic wastewater from buildings constructed at the site of a future data center. The facility will initially treat up to a half-million gallons per month of municipal wastewater but is sized and designed for increased future flows. Treatment will be through three facultative lagoons and chlorine disinfection. The treatment process will produce Class C recycled water to be supplemented with irrigation groundwater, applied to 30 acres of reuse fields for growing alfalfa and silage corn in the growing season, and held in two storage lagoons during the non-growing season.  

Operation of the wastewater treatment and reuse facility is expected to begin in 2024, shortly after a final reuse permit is issued. The permit would authorize reuse operations for nine years and establish monitoring requirements, limits on nutrient and hydraulic loading, and conditions established by DEQ to protect public health and the environment.  

The permit materials are available for public review at DEQ’s State Office (1410 North Hilton Street, Boise, Idaho 83706), DEQ’s Boise Regional Office (1445 N. Orchard Street Boise, ID 83706), and on DEQ’s Public Comment Opportunities page. Written comments will be accepted through May 9, 2024, until 5 p.m. MDT. Submit comments electronically on DEQ’s website or by mail or email to:
