In July the Doubletree Hotel ~ Atlanta Buckhead invested in a plumbing project to recycle their refrigeration compressor cooling water. The under $9,000 investment paid back in two weeks from reduced water bills! By year end, the Doubletree estimates the project will save 1 million gallons of water.
Previously this water-cooled system sent the used water down the drain. Always striving to improve environmental efficiencies, General Manager David Rossman and his team installed a dedicated re-circulation loop for the walk-in coolers which streamed the water back into the existing cooling tower.
In addition, the City of Atlanta is crediting the hotel 2.3 cents for every gallon of water that is safely reused! What a way to reduce the burden on the fragile water and sewer system in our city.
Check out these impresssive ROI numbers:
In the first three months since the work was completed, the Doubletree Atlanta-Buckhead saved 695,334 gallons of water and $15,993 in water/sewer expense.
