1. New buildings

a) Require all new buildings use 30 percent less water – partial success through DFCM & LEED standards

b) Dual plumb all new buildings – pilot projects (NHMU & S. J. Quinney College of Law) –further study needed

2. Existing buildings

a) Replace existing toilets with 1.28 gpf – partial success

b) Replace fixtures with low use – partial success with showers, lavatories

3. Convert one percent of existing turf to xeriscape per year – success, ongoing

a) New building conversions

b) One acre+ per year in stand alone projects.

4. Increase the efficiency of new building cooling by 10 percent – success through standards and energy efficiency efforts.

5. Use non potable water for irrigation – success

a) Use well water for irrigation – well irrigation started in 2014, planned growth for the program

b) Capture rainwater – pilot projects (NHMU)

c) Use well water for process water – planned

6. Increase infiltration of precipitation to balance water usage and reduce storm water runoff – partial success

a) New standards for storm water management (Retain 10yr)

b) HPER mall redesign
