The Dalles City Council got an update on the wastewater treatment plant build out during a special worksession on Monday evening.  Mayor Steve Lawrence says they will be receiving at a Council meeting on December 12 the completion of the design for a second phase that is enlarging capacity and find a way to use the methane gas the plant produces to power it.  He adds it will cost about 11 million dollars, but they will be able to fund it without bonding or raising sewer rates.  The plan is to have construction start in January, with work to be finished by the end of next year.  Some changes are being made to the design to accommodate challenges that arose in the upgrade, including a new structure to house the headworks, additional piping work, and a second backup power generator to handle the electrical loads of an upgraded plant.
