California city finds early success solving its pinhole water leak problem
The city of Folsom has experienced a significant decrease in pinhole leaks in copper water pipes in local residences since adding orthophosphate to the water system. This past summer, Folsom experienced what residents dubbed “a pinhole leak apocalypse.” Water leaks in homes developed nearly 1,400 times. On the recommendation of consultants, the city started adding orthophosphate to the water treatment system in October. Folsom’s environmental and water resources director, Marcus Yasutake, says it’s had the desired effect.
