King LEED 2 Water Resources

How does the building preserve water resources?

Recycled Water Supply for Toilets and Urinals

Reclaimed Water Sign

King Library was built with dual plumbing to deliver recycled water to toilets and urinals.

King Library's plumbing supply system was installed with separate supply lines for toilets and urinals, in addition to the supply lines for potable (drinking quality) water so that the building could take advantage of South Bay Recycled Water when it became available.

Four years after the library opened, recycled water mains were installed in San Fernando Street making recycled water available.

After a lengthy design and permitting process to ensure that recycled water is kept separate from potable water, construction began in March 2010 to connect the recycled water supply in the street to the pumps in the mechanical room so recycled water can finally be used.

Use of recycled water for flushing not only displaces the use of potable water, it provides the local water treatment plant with a use for its treated water.

This means that less fresh water is discharged from the treatment plant into the San Francisco Bay, helping to maintain the bay water's natural salinity and preserving the local ecosystem.

Less-thirsty Landscape

The landscape design for the building included plants that need less water.

The campus plant palette is being revised to include more drought tolerant, recycled water-tolerant and native plant species.

SJSU is working on its irrigation system to isolate it from the potable water system. When this is complete, recycled water will be used to water much of the campus landscape, including the King Library site.

Low Flow Faucets

King Library was designed with low flow faucets at all sinks and low flow toilets.

Green Site Management

The site is maintained to avoid discharging dirt, fertilizers, pesticides and other contaminants into the storm sewers which discharge into the San Francisco Bay.
