The Bull Run water system is designed to capture and store rainfall from the rainy season to provide an adequate water supply during the dry summer months. The city has an additional, high quality water source in the Columbia South Shore Well Field which augments summer supply. This groundwater source is the state's second largest water supply after Bull Run.
Since 1993, the Water Bureau has developed annual contingency plans for summer season supply. Each spring an interdisciplinary team evaluates a range of variables related to water supply and demand. These include available water supplies, past and projected water demand, the impacts of regional conservation programs, public health protection, water quality, and native fish protection to name a few.
The plan is used to guide operational strategies to ensure the Portland Water Bureau continues to provide high-quality drinking water to our customers while meeting all of our system’s needs.
