The Portland Water Bureau has wholesale contracts with 19 water purveyors in the Portland, Oregon metropolitan area including cities, water districts and private water companies. In 2009, the City signed a contract with a 20th wholesale customer, the City of Sandy, for water to be delivered beginning no later than November 2013. Portland can potentially sell water to a wholesale population of more than 440,000 and routinely provides wholesale service to more than 360,000 people. Annual wholesale water sales account for approximately 10-15 percent of annual water sales and 40 percent of annual water demand.
The City of Gresham was Portland's first municipal wholesale customer. Gresham citizens first received Bull Run water on February 1, 1912.
During 2006 and 2007, five of the 13 cities and public water districts signed 10-year agreements, and eight of them signed 20-year agreements. These agreements are virtually identical except that the 10-year agreement customers pay a higher rate of return to the city than those with 20-year agreements. Six small water companies have agreements that renew every five years.
