Water Saving Initiatives
Domestic Water Saving Initiatives
Water-cooled equipment now uses chilled water from the central chilled water system instead of domestic, deep aquifer water.
Installed shallow aquifer wells are now used in aquaculture research on west campus, to reduce the usage of deep aquifer well water.
Water saving flush valves, showerheads, and faucet valves have been retrofitted and are part of our design standards for new construction.
Reclaimed Water Irrigation System
The University of Idaho is now irrigating over 150 acres with reclaimed water, saving up to 100 million gallons per year from the deep aquifer. The University expects to reduce the areas irrigated with domestic water use by 50% in next 5-10 years. Certain areas of campus will remain under domestic irrigation because the areas are around Housing units that are required to be irrigated with domestic water by state and federal guidelines.
In the last few years, the University has added 45 acres of automated irrigation systems, the majority of it on the reclaimed water system. Automated irrigation reduces water use over hand-watering by an estimated 50% and allows capacity of the water infrastructure to be used nights for more efficient water use.
