The City of Island City and the City of Halfway were honored to receive the 2018 Water Project of the Year and Wastewater Project of the Year, respectively, at the annual Eastern Oregon Subsection AWWA/PNCWA Operator’s Conference.
Water Project of the Year – City of Island City
Due to increasing nitrate levels in the City’s backup well, the City of Island City found itself relying on one well and reservoir to meet system demands. While the City had adequate water supply capacity, there was limited water supply and storage reliability. The City teamed with AP to develop a Water System Master Plan and provide funding assistance, permitting, land acquisition, water rights, environmental reporting, cultural resource evaluations, and design and construction engineering services for the identified improvements. The project included developing a new 500-foot alluvial filter pack supply well with a pumping capacity of nearly 1,500 gallons per minute, a new 500,000-gallon storage reservoir, updated system controls, improved distribution system looping to improve water quality, and increased fire flows and hydrant coverage.
Wastewater Project of the Year – City of Halfway
The City of Halfway owns and operates a wastewater collection system and treatment and disposal facilities under a National Pollutant Discharge Elimination System (NPDES) Permit. The City hired AP to complete a Wastewater Facilities Plan Update that identified deficiencies and improvements for the existing wastewater treatment and disposal facilities to correct problems and address current and future NPDES Permit compliance issues. The City determined that the best long-term alternative to dispose of its wastewater was to eliminate the direct discharge to Pine Creek and take effluent from the wastewater treatment facility, store it in a storage pond during the winter months, and use the stored wastewater for irrigation during the summer months. The improvements project consists of an effluent pumping station at the Wastewater Treatment Facility, a transmission line from the City’s treatment facility to the irrigation storage pond site, construction of a storage pond, and construction of an irrigation pumping station and transmission line to a center pivot that irrigates a grass pasture for use by the cattle operation.
