by Brianna Crandall — January 7, 2011—Green Energy Management Services recently announced it has signed a five-year water efficiency installation and maintenance contract with Keystone Holdings, a residential and commercial real estate developer located in Miami, Florida. The project entails installing and maintaining Airlock valves across Keystone’s 14 properties, beginning with Keystone Palms, a residential property in Miami.
The contract is estimated to provide Keystone Holdings with as much as 30 percent annual savings in its water and sewer costs at each of its properties. As compensation for the project, the Green Energy Management will receive 50 percent of the savings over the life of the contract.
Airlock is a proprietary, patent-pending device that more accurately measures water flow from a water provider. Air typically accumulates in water pipes before it reaches the meter, artificially raising meter readings, explains GEM. Airlock compresses the accumulated air in the pipes. The water then flows through the meter with the air undetected, and the result is a reduced water bill, says the company. Airlock is cast in surgical stainless steel, assembled in the U.S., and certified by the NSF.
