EXPERT PANEL RECOMMENDS NEW WATER TREATMENT PROCESS FOR LAKE OSWEGO AND TIGARD
Posted: June 14th, 2010 3:44 PM
A panel of national experts in water treatment and public health recommended last week that the cities of Tigard and Lake Oswego pursue conventional drinking water treatment plus ozone to best meet their future water treatment needs.
The two communities entered into a partnership in 2008 to share drinking water resources and costs. Lake Oswego's water supply system is near capacity and key facilities need expansion and upgrades. Tigard residents need a secure, dependable water source. Both cities want to keep water affordable for their customers and sharing the cost of new infrastructure to serve both communities does that.
The recommendation validated a 2007 engineering report that provided support for the partnership agreement, that conventional treatment meets water quality requirements. The panel recommended ozone in addition, because it is capable of addressing emerging concerns about currently unregulated contaminants. The panel determined that adding ozone as an additional treatment barrier would best protect public health in the long term. Ozone would proactively ensure the best taste year round and would reduce the amount of chlorine used for disinfection, among other benefits.
Additional work will determine costs for this portion of the overall project costs before each City Council is asked to confirm the recommendation. However, of the total 18 alternatives examined, this treatment recommendation was considered mid-range in terms of cost.
Interested water customers and citizens in neighboring communities are invited to learn more about the project at an open house later this month.
