The new City of Airway Heights Water Reclamation Plant is being designed to provide a new source of water to meet the growing demands of our community, and will eliminate our wastewater discharge to the
Spokane
River
. It will be located North of McFarlane Road and South of 21st Avenue, bounded by Russell Street to the East and Lawson Street to the West.
The first phase of the plant is being designed to treat up to 1 million gallons per day (MGD) of wastewater. A second phase is planned in the future to increase the capacity to 1.5 MGD, which should accommodate the City’s needs over the next 20 years
The plant will treat wastewater to Class A Water Reclamation and Reuse Standards that will provide water suitable for a wide variety of beneficial reuse. This highly complex treatment will involve advanced biological treatment, coagulation and membrane filtration, and additional disinfection, plus removal of nitrogen to protect groundwater quality. It is anticipated that the new plant’s reclaimed water will be used for aquifer recharge, commercial and industrial uses, and irrigation applications.

Project Background
In 2003, the City of Airway Heights recognized that the West Plains was experiencing difficult water resource and wastewater challenges that could significantly impact our residents and region. The City was reaching wastewater treatment capacity available through an agreement with the City of Spokane. In addition, local drinking water resources were known to be limited.
From 2003 through 2005, the City completed a wastewater facilities planning process, which included a variety of technical studies. A Wastewater Steering Committee, which included representatives from several stakeholder groups, was formed and met to review planning and study elements, and provide advice and perspectives to City staff and consultants.
During the facilities planning process, three proposed treatment alternatives were reviewed. It was recognized that the best solution was to keep water in the region, to address both wastewater capacity and limited water availability issues. To achieve these goals, protect the environment, and provide service to residents at the lowest possible cost, the decision was made to build a new City of Airway Heights water reclamation plant. This plant will eliminate discharge to the Spokane River, helping to improve water quality, and provide a new source of water to meet the growing demands of our community.
The new plant will treat wastewater to “ultra” clean Class A reclaimed water levels, and the water will be used for non-potable water needs and to recharge our stressed aquifer. This project provides our community with an excellent opportunity to address the water-related challenges that we face, while protecting our environment.
The planning process also involved review of four candidate sites for the new reclamation plant. Based on scoring of over 15 criteria, the City selected the site located in the southerly portion of the City’s service area, bounded by McFarlane Road on the south, Russell Street on the east, 21st Avenue on the north, and Lawson Street on the west. This site will allow for some expansion of the City’s sewer conveyance system and the ability to construct a reclaimed water distribution system to supply water to commercial and industrial customers for reuse.
