History
The Water Plant was first established on Mortimers Island in November of 1903 and operated until the passing of the Clean Water Act in 1972. In 1974 the City completed construction of a new water plant and river intake structures to increase production capability as well as to keep up with the new federal regulations.
The Water Plant received a major upgrade and rebuild beginning in March of 2004 to modernize our facilities and increase our production capability to 3 million gallons per day. The second half of the upgrade was completed in March of 2007.
Our water sources are the Snake and Weiser rivers. The City also has one well that was in use from 1949 to 2006 but, following an EPA regulation change in 2006, and the capacity of the new water plant, the City chose to close this well and keep it active as an emergency backup only.
Our water reservoirs store a combined total of 3,524,000 gallons of water providing drinking water and fire protection within two pressure zones through over 38 miles of piping.
Fluorides are not added to the water, however, testing indicates there is .58 mg/L (parts per million) of naturally occurring fluoride in our water.
