Newberg, Oregon, is located approximately 25 miles southwest of Portland in Yamhill County. Geographically separated from Portland by the surrounding Chehalem Mountains and located in a broad valley created by the Willamette River, Newberg is home to numerous vineyards and is known as the “Napa Valley” of Oregon. Newberg is a fast-growing community of just over 22,500 people with a diverse economic base. Located at an elevation of only 175 feet above sea level and relatively close location to the Pacific Ocean, Newberg enjoys a moderate climate.

The City of Newberg’s Operations Division operated and maintains the water and wastewater treatment plants, aquifer water supple, three reservoirs, numerous springs, pump stations and a recycled water system for the municipal golf course. Newberg operates a sand and gravel aquifer just south of the Willamette River. The “raw” water pulled from this source is naturally filtered by the aquifer and pumped over and under the river through pipelines to the water treatment facility for further treatment. The wells at the aquifer provide Newberg with 100% of its water supply. The City maintains three 4-million-gallon (MG) reservoirs in the surrounding hills to provide residents with a three-to-five-day potable water supply.
