The Dalles City Council has given the go-ahead to discuss a proposal from Design LLC, the local construction arm of Google, to develop an Aquifer Storage and Recovery program to expand municipal water supplies.  The concept involves treating surface water during the winter, and pumping it down into the aquifer for later recovery to meet summertime demands, a technology already being used or evaluated by a number of Oregon water systems as a lower cost and effective alternative to constructing surface water storage systems.  City Public Works Director Dave Anderson says Pendleton has had a successful ASR program for about a decade.  He adds an ASR program could save the City money by delaying the need to expand Crow Creek Dam and future expansion of the Wicks Wastewater Treatment Plant.  Councilors approved entering into negotiating a development agreement with Design LLC.
