Water and sewer service is provided by the City of Oakridge. The City of Oakridge water system consists of two reservoirs, providing just over 2 million gallons of storage capacity. A well field, which has five active wells capable of pumping 1.6 million gallons per day, supplies the water for the City.

The City of Oakridge constructed a new wastewater treatment plant in 1994, and has been active in maintenance and general upkeep to keep the facility modern and running properly. The plant is located south of the Willamette River to the southwest of the City, but outside of the City limits on U.S. Forest Service Property. In 2003, the City renewed permits with DEQ and the USFS for plant operation and sludge application in cleared fields surrounding the plant. Construction was done to EPA class II reliability standards using an extended aeration activated sludge treatment system.

The City has prepared a Policy and Procedures document for the systems which is provided to new customers and upon request. The document provides rates and charges for the services and other information useful to customers.
