In 2015, the City of The Dalles embarked on a Progressive Design-Build project to upgrade their wastewater treatment plant. Since January of 2017, MCEDD has been supporting the City in management of labor standards for the project to ensure compliance with state and federal regulations during the construction. The goals of the project were to provide residents with sustainable and reliable treatment facilities that were in full compliance with state and federal regulations. After four years of planning, design and construction, the project is complete. The many upgrades to the plant, which included a cogeneration facility, will allow the City to treat peak wastewater flow rates while promoting sustainability by lowering operating costs and generating clean energy. The upgrades have also increased plant capacity from a peak flow rating of 7.7 mgd to 13.2 mgd (the projected capacity for the year 2037).
