Phase 1 of the Elmore-Ada Water Project evaluated the water supply and delivery opportunities for the region between Boise and Mountain Home along the I-84 corridor, which spans the region framed by Mayfield, Orchard, Simco Road and the Kuna-Mora road sections of western Elmore and eastern Ada counties.

One aspect of Phase 2, which is currently underway, includes the continued design-engineering work and further financial analysis of the three pipeline alignments which were identified as being feasible options.
