2 Agenda 1. Water Balance Overview 2. Progress at Joint Base Lewis McChord (JBLM) and Ft Carson 3. Next Steps Assistant Secretary of the Army (s, Energy & Environment)

3 Net Zero Water Team Project management Planning Domestic Project management Planning Central plants/industrial Project management Central plants/industrial Kate McMordie Brian Boyd Jim Cabe Marcus De La Rosa Elisabeth Giever Jennifer Williamson Benton Russell Scott Brown Doug Dixon planning Ray Reilly planning Susan Loper GIS Subcontract providing specialized expertise for water balances PNNL auditing team Roadmap team Water Savers LLC Assistant Secretary of the Army (s, Energy & Environment)

4 Water Balance Overview Water sources Municipal supply Water uses Metered uses Maximize alternate water sources On-site freshwater Unmetered uses Net Zero Alternate water Losses Reduce freshwater demand and increase efficiency Assistant Secretary of the Army (s, Energy & Environment)

Pools Dining Estimate water use by end-use Compare to total supply Recreation/Gymnasiums

5 Water Balance Approach Collect water supply data Audit buildings Barracks Central Plants Gather typical water use data Extrapolate data to building stock Family Housing Motor Pools Dining Estimate water use by end-use Compare to total supply Recreation/Gymnasiums Office Buildings Landscape/Irrigation Assistant Secretary of the Army (s, Energy & Environment)

6 Data Needs for Water Balance Data requested during site visit: Annual occupancy data for military, family housing, civilian, and contractors Barracks Barracks Utilization Report (AKA BUR ) Morale, Welfare, and Recreation (MWR) number of visitors, data on pools, other water intensive Dining number of daily meals served, annual operating days Hospital number of beds, occupancy rate, equipment list, central plant logs Motor Pools number of vehicles on post, estimated number of annual washes Assistant Secretary of the Army (s, Energy & Environment)

7 Data Needs for Water Balance GIS maps requested during site visit: Buildings Irrigation system Water distribution system Central plant distribution Water meter locations JBLM Building GIS Assistant Secretary of the Army (s, Energy & Environment)

16 JBLM and Ft Carson Lessons Learned: Scheduling with the right people has a big effect on success of site visit Observe buildings of different eras and different remodel activities Sites may have industrial equipment inventory available for use Central plant logs tell a story Operation and maintenance of water-using equipment is critical to know Central Vehicle Wash Facility at Ft Carson Assistant Secretary of the Army (s, Energy & Environment)

JBLM and Ft Carson Initial Observations: Domestic plumbing is a large water demand at training-dominated sites Irrigation is a significant water use

17 JBLM and Ft Carson Initial Observations: Domestic plumbing is a large water demand at training-dominated sites Irrigation is a significant water use at both sites Both sites have remodeled restrooms in older buildings Renovated bathroom at JBLM Assistant Secretary of the Army (s, Energy & Environment)
