The City of Hood River’s extension of the municipal wastewater plant’s outfall pipe farther into the Columbia River is wrapping up. The City was required to do the work by the Department of Environmental Quality after the 2006 rush of debris from the Hood River changed where the proper mixing zone in the Columbia River for treated wastewater is. City Manager Steve Wheeler says the other portion of the project extends the path to the Hook area. Asphalt for the path should be finished by the end of the week.
