Abstract: Zeta Rod® Water Management Systems were selected to be utilized as the water treatment system of choice for the recirculating open-loop chillers, heat exchangers and cooling towers for the two HVAC Central Plants at a U.S. Government Data Facility in the Southeastern United States. The purpose of the system was to deliver significant water conservation while protecting critical cooling equipment in a manner consistent with a well managed traditional chemical water treatment program. The Zeta Rod system was included as part of an Energy & Water Conservation Project implemented by the Tennessee Valley Authority (TVA).
- 22% less make up water used
- 65% less waste water sent to the sewer
- 5.8 Million gallons of water saved during the first year

The application of a Zeta Rod Water Management program allowed the Crime Lab to earn the LEED point under Water Efficiency and Innovation in Design. In particular, a measurable non-regulated water use savings that is at least 10% of the total calculated baseline design (166,000 gallons for the Crime Lab) for regulated (fixtures) water use is eligible for an exemplary performance ID point under WE Credit 3. This project conservatively documented savings of 674% of the baseline calculation for an annual total of 1.1 million gallons.

Within 60 days, results delivered by the Zeta Rods were significant:
• Reduced water consumption per vehicle from 48.75 gallons per car (gpc) to 35.51 gpc; a net reduction of 27% per vehicle
• 235,000 gallons of water saved in 60 days
• 38% drop in the total per vehicle washing cost
