Permeable Pavers
To manage rainwater on campus, we incorporate permeable pavers into new construction to allow for better infiltration of the runoff rather than having it run directly to the river that borders the campus. Permeable paving systems are porous, so they allow water to infiltrate the pavement and drain into the ground or sub-base rock underneath. The permeable pavers have open cells that are filled with gravel or grass and are designed to let water enter into their surfaces, get detained in the rock base, and absorb into the ground beneath. Paving systems that use hardscape surfaces (concrete, asphalt, or compacted gravel) will collect stormwater, causing it to pool or run off. Instead, permeable pavers have a porous surface that naturally mimics and recreates the way the ground reacts to rainwater. The rate at which the water drains into the surface depends on the specific type of permeable paving system used.

Optional documentation
Current water billing practices do not provide insight into which water meters are associated with irrigation use vs. non-irrigation use. Additionally, considerable portions of the campus are irrigated with non-potable water sourced from the Boise River through a local canal company. This water is not billed on volume, but rather based on the amount of land & water rights held by the university. This non-potable irrigation water is not currently metered and is excluded from the reported totals. Diverted water that is not used by irrigation district shareholders is returned to the Boise River.
