From April 20-24, 2009, three senior managers from the Wastewater Management Authority visited counterparts in King County to learn best practices on water treatment facility management through site visits to three treatment plants.  King County provided WMA managers with hands-on training, demonstration and exercises, and presentations on key priorities areas identified by WMA.   Based on the success of USAID Environmental Cooperation-Asia (ECO-Asia)-facilitated twinning, both parties discussed a plan to leverage their own resources to transform their relationship into a long-term partnership.
