This prerequisite is new in LEED 2009; it does not apply to previous versions of LEED. All design and construction LEED projects have to beat a water use baseline by at least 20% to meet this prerequisite. The baseline is determined by assuming all fixtures meet national codes, as laid out on a fixture-by-fixture basis in the credit requirements. For LEED for Existing Building: Operations & Maintenance the threshold depends on when the facility was constructed or last renovated.
