  • 1. Hosted by: Office of Senator Richard Burr Office of Senator Kay Hagan North Carolina Military Business CenterSponsored by: Presenting Sponsor Gold Sponsor Silver Sponsor
  • 2. Net Zero Water Installations & FacilitiesThis roundtable will address:• Conservation and efficiency in use of fresh water• Improved integrity of distribution systems• Repurposing greywater• Harvesting and reusing rainwater and storm water• Desalination of briny, brackish or salt water• Recharging wastewater to aquifers
  • 3. Net Zero Water Fort Bragg InitiativesCurrent Initiatives (Installation/Agency: Fort Bragg)1. Utilization of non-potable water sources for non-potable needs.2. Publication and implementation of the Fort Bragg Water Conservation Policy.3. Limiting access to potable water sources.5.Installation of water meters at all new construction to monitor water usage.6.Construction of a tanker purging facility to reduce water use during purging.7.Water use awareness and education through the Green Boot Program.
  • 4. Net Zero Water Fort Bragg Future NeedsFuture Needs (Installation/Agency: Fort Bragg)1. Increase the utilization of non-potable water sources2. Installation of water meters on existing construction for monitoring purposes3. Construction of a water purification unit for treatment of Oil Water Separator water5.Outreach and Education of Fort Bragg population6.Information-only billing to promote water use awareness7.Rain water harvesting systems
  • 5. Water Conservation MCIEAST InitiativesCurrent Initiatives (MCB Camp Lejeune)1. Developed a Potable Water Conservation Plan3.Installing water conserving faucets, showerheads, toilets and urinals in buildings and a closed loop vehicle washrack system.3. Using non-potable water for golf irrigation.6.Installing stormwater Low-Impact Development (LID) measures, including infiltrationbasins as well as rainwater harvesting.7.The Base continues to work with ONWASA and the City of Jacksonville in an effort toprotect the resource
  • 6. Water Conservation MCIEAST Future NeedsFuture Needs (MCB Camp Lejeune)3.New drinking water supply wells will soon be constructed on main side and VeronaLoop.5.Projection to construct a consolidated 12 mgd membrane filtration plant to serve MCIEAST-MCB CAMLEJ.3. Continue to document aquifer drawdown cycles, long-term water level trends, and water quality conditions in the Castle Hayne Aquifer and in adjacent aquifers at key locations throughout the Base.4. Continue to investigate and identify new well-field locations for future well development
  • 7. Net Zero Water MCAS Cherry Point InitiativesCurrent Initiatives (Installation/Agency: MCAS Cherry Point)4. Reclaimed water for irrigation5.Reclaimed water to replace potable water in processes at the Waste Water TreatmentPlant6.Rainwater harvesting7.Low-flow toilets and urinals
  • 8. Net Zero Water MCI East Future NeedsFuture Needs (Installation/Agency: MCAS Cherry Point)3.Building audits4.Reclaimed water to replace potable water in the production of steam at the CentralHeating Plant5.Potable water storage tank mixing to improve water quality and eliminate distributionsystem flushing6.Fill port in reclaimed water system for tanker trucks7.Cooling tower improvements to eliminate open loop cooling8.Distribution system leak audit
  • 9. Net Zero Water NC National Guard InitiativesLike energy conservation, a net zero water approach requires command emphasis, sensiblenear-term milestones, and use of cutting edge technologies to achieve long-term success.Current NC National Guard Initiatives1. Annual Conservation Policy establishes over-arching vision: “NCNG personnelwill….integrate conservation efforts into “day-to-day” operations and missions, to the extentthat missions allow.” Building occupant behavior modification is key.2. Near-term water conservation goals: 2012 -- 5% reduction. 2013 -- 10% reduction.6.Field units receive monthly, quarterly, and annual feedback to track actual results.7.Retrofit Options (older infrastructure) – distribution system repairs, native landscapingmaterials/xeriscaping, recycled (non-potable) irrigation, “water-wise” (low flow) devices.8.Net Zero Water Strategies (new construction) – holistic, LEED-based water conservationdesign from inception; innovative recycling of water discharges from all sources.
  • 10. Net Zero Water NC National Guard Future NeedsWe use a mix of supply-side and demand-side water conservation strategies to stretch ourbudget as far as possible. Some ambitious efforts may require additional investment*.Future Improvement Strategies/Needs (NC National Guard)5.Supply-Side Water Conservation Strategies: a. Review water utility accounts to ensure we qualify for lowest cost rate schedule. b. Take advantage of special utility company rebates or discount programs. c. Analyze water bills for sudden rate changes or usage spikes (possible line breaks?)6.Demand-Side Water Conservation Strategies: a. Maximize number of water efficiency/retrofit projects each fiscal year.* - High priority on distribution system repairs and upgrades to prevent water loss. - Equipment swap-out (i.e., “water-wise”, low-flow fixtures). - Gradual site landscaping evolution in favor of xeriscaping and native plants. b. EVERY new construction project will follow LEED water conservation approach.* - Extraordinary focus on innovation – esp. discharge recycling opportunities. - Complete linkage of the site (landscape) to the building systems (architecture).
