Transcript of "Award-Winning Water Supply System Lowers Usage and Costs"

  1. 1. PROJECT HIGHLIGHTS Award-Winning Water Supply System Lowers Usage and Costs T he Georgia Bureau of Investigation (GBI) headquarters in Decatur had been coping with high nonpotable water usage and costs to support systems fed by the county water supply. In fact, the GBI consumed 1,000,000 gallons month—costing $34,400 annually. From this information, they also developed a b ­ aseline meter reading for the winter months of just over 140,000 gallons per month. The source of the additional 230,000 gallons per month on average was then pinpointed —the cooling tower make-up water and ­rrigation systems. i To lessen county water usage, the GBI staff developed an inno­ vative alternative water capture s ­ ystem and enlisted McKenney’s engineering expertise and capa­ bilities to implement the system. It consisted of two cisterns with 10,000-gallon total storage capacity and an on-site well that pumps water to the cisterns.

The Challenge žž Calculate water usage and costs history žž Pinpoint source of excesses žž Devise supplemental water supply solution The Solution žž Dig an on-site well and install storage cisterns žž Capture condensate and r ­ ainwater for cisterns žž Pipe water from cisterns to cooling tower and irrigation systems The Results žž Cost savings of $20,000 annually žž Project earned 2013 GASFA ­Innovation Award žž System payback of four years annually, which allows the system to pay for itself in just four years. With such significant results—not only in cost savings but also reduced environmental impact—the project earned a 2013 Innovation Award from the Georgia Association of State Facilities Administrators (GASFA). It also paves the way for other state agencies with a high demand for non-­ otable water to enlist a p similar solution to lower water use and costs, provided it has the infrastructure to support an on-site well and water storage system.
