It’s not going to be cheap, but Bend City Councilors say it will be an investment in the City's water system. Wednesday night, on a five to two vote, Councilors voted to continue designing a membrane filtration system. Councilor Mark Capell says several engineering firms recommend the City continue using surface water. “All four of those engineering firms came basically to the same conclusion and that is to continue moving forward on surface water. The one complaint I heard from citizens is that HDR (the engineering company) was self serving in saying go for this.” Analysts say membrane filtration is the best way to screen out any debris should a fire ravage the Bridge Creek Watershed. But it could cost up to $25-million. That's something Councilor Jim Clinton balks at: “At our last meeting, I decided that this was looking to me like this was not a path that was in the best interests of the rate payers of Bend.” The Council can still change it's mind and stop the project, but for now City Manager Eric King says it's in the best interests of the City to continue designing the more efficient filtration system.
