In 1968, the Syringa Heights Water Association was created to help 150 households outside the boundaries of the city of Sandpoint jointly fund a water system. The members used a federal grant to build the system.
In 1982 the association reformed itself as a water district, a legal, separate entity as described in Idaho Code. It did so to grow the system and to establish a legal relationship with the city of Sandpoint.
Sandpoint annually sells about 17,000,000 gallons of water (as of 2019) to Syringa Heights Water District. The city considers Syringa to be a “large user” and charges Syringa water rates according to that class. Any quantity of water that Syringa uses over that amount is charged by the city at the next highest rate.
Currently, the system has 211 billed users as of January 2019. New connections are available.
