Commence an aggressive campaign to locate and repair dripping faucets and toilets.  Many bathrooms have small drips from the faucets and/or small drips from the pipes underneath the sinks.  In additon, many toilets have small drips from the flushing handle or from the main pipe.  These small drips are seldom reported unless they become major drips and cause a flood.  The staff bathroom in my area alone has had a small drip for at least the last 6 months.  Searching out these drips center wide may lead to

a.) less waste of water in this time of significant drought

b.) a decrease in the cost of UCSF's overall water bill

c.) help to maintain pipes and grout by minimizing rust, mold, etc.
