During FY 2001, the grounds team at the Department of Energy's Pacific Northwest National Laboratory (PNNL) applied state-of-the-art grounds management techniques to maintain the landscaping surrounding the PNNL campus. PNNL conserved approximately 114 million gallons of water by using the latest technology to gather data on watering systems, using best-practice landscape methods, monitoring soil moisture, and fertilizing. In addition, PNNL saved approximately 1.5 million gallons of water and subsequently saved almost $3,000 in waste water fees from the city. The facility also avoided sending water into the sewer system, which saved $33,000 in sewer costs. The innovative thinking of this team, which has included the use of predictive water flow models and soil analysis, has yielded substantial environmental, energy, and cost benefits.

Using a non-traditional water conservation and cost-savings concept, DOE's Lawrence Livermore National Laboratory's (LLNL) Plant Engineering Instrument Shop and Energy Management Program saved an estimated 72,600 gallons of water per year through their Drain-Down Recovery Project. LLNL's project team came together to prevent water waste during the repair of heat and cooling water circulating systems. The team's drain water recovery program reuses most building system water, as well as anti-corrosion and scale-inhibiting chemicals. The idea of the project is simply to collect drain-down water and return it to the system following repairs, rather than waste it down the drain. The project realized savings in three areas: the cost of water; the costs of anti-corrosion and scale-inhibiting chemicals (which total more than $9,000); and, reduced labor costs (by $52,600). With an amazing payback period of just three months, LLNL's project effectively conserves water, prevents pollution, and reduces maintenance costs.

Severe drought conditions in San Angelo, Texas, home of Goodfellow Air Force Base, spurred the Base's Water Conservation Team into action during FY 2001. Partnering with the City of San Angelo, the Base adopted the city's water conservation and drought plan, and expanded its own water conservation measures. The Base's Water Conservation Team decreased water consumption by more than 16 percent, saving more than $73,000 in utility charges. Through a $3 million energy savings performance contract, the Base has completed $375,000 worth of water conservation projects, installed efficient water fixtures, implemented water-efficient landscaping, and developed and maintained an aggressive water conservation awareness program. With the ESPC, the Base realized a savings of 237 million gallons of water and $48,000 per year. Also, to keep water use to a minimum, more than 60,000 square feet of lawn areas were converted to xeriscape landscaping or rock gardens and 1,300 work orders were completed to stop leaks and replace inefficient water fixtures.
