An energy-saving idea from Town Staff means savings in electricity consumption at the Craigleith Wastewater Treatment Plant.
Following direction from Town Council to look for ways to save energy and dollars, Staff at the Plant decided to try using reclaimed effluent water, instead of potable water, for several maintenance procedures.
The Plant’s staff of Rob Fleming, Maurice Dempster, Scott Pendleton, Brian Vail and Evan Orser developed the idea. John Caswell, Manager of Water and Waste Water Services added that it was urging by Town Councillor John McGee that inspired the team to look for ways to reduce energy use and operating costs.
The result is a reduction of about 80 per cent in potable water usage at the Waste Water Treatment Plant.
"The Waste Water Plant group has made some significant changes to reduce hydro and potable water consumption at the Craigleith WWTP,” said Fleming, Operator in Operational Responsibility. “Diligence and participation by all of our staff was a key to making this happen successfully.”
The idea has paid off handsomely. In 2007, the Plant used 11,512 cubic meters of potable water, costing $37,841. Figures for 2008 show those numbers were cut to 2,246 cubic meters of water used, costing $9,129.
Caswell added that the new method also means big savings, in electricity us, which translates into reduced costs as well environmental benefits. The Plant’s electrical use dropped from 41,852 kilowatt hours (kwh), in 2007, to 35,525 kwh in 2008. The reduction meant a saving of just under $9,000.
“This is a real success story driven by innovative plant staff,” Councillor John McGee said. “The water savings is equivalent to water used by approximately 50 households.”
McGee added, “Our 2010 draft budget is proposing an energy audit of all Town facilities and we expect to see additional saving in our operating costs as a result. Rob and all the Staff should be congratulated for leading the way toward a more sustainable community.”
