Butler Drive WRF, Arizona

What is it?

A 37,850m³/d wastewater treatment plant serving the city of Peoria, AZ. The plant has the potential to be expanded to 49,205m³/d in future.

Who is responsible?

Black & Veatch provided design and construction-phase services for the $135 million facility, which is owned by the City of Peoria. Sundt Construction was the main contractor.

What makes it special?

• The City of Peoria has met the dual challenges of wastewater treatment and water supply to a rapidly growing desert community with one of the US’s largest membrane bio-reactors by capacity.

• The 30,280m³/d of treated effluent currently produced by the plant is reused in aquifer recharge, enabling the City to earn valuable water withdrawal credits.

• The plant’s low-profile external appearance was integral to gaining public acceptance. The facility includes compact structures that are largely below ground.
