PORTLAND -- The Portland Water Bureau had to activate groundwater wells in the Columbia South Shore Well Field Tuesday, after a leak was detected in the Bull Run watershed system.
The leak was found on June 30th, in one of the 50-inch diameter supply conduits from the Bull Run watershed into the city, according to bureau spokesman Tim Hall. He said it will take about two days to repair the conduit.
In the meantime, the water bureau will augment the Bull Run supply with drinking water from the Columbia South Shore Well Field.
"Thanks to careful planning and investment, we have two high quality sources of water available to us," said Portland Water Bureau Administrator David Shaff. "When there is a disruption in the Bull Run water system, it's tremendously comforting to know that we can turn to our Columbia South Shore Well Field as a back-up and supply all our customer's needs."
The groundwater system may contribute up to 30% of supply during the repairs. Hall assured that customers should not notice any difference in the taste of the water.
The public will be notified when the well field is shut down and the water supply returns to 100% Bull Run water.
