Why won the stormwater and wastewater be separated in the entire Custer Basin?
Studies of the combined sewer system have shown that the proposed additional storage and upgraded treatment for CSO’s in the Boulevard CSO Basin is the most economical and effective approach to meeting water quality standards. Stormwater runoff from urban areas is polluted with solids, bacteria and heavy metals and will require additional controls in the future if water quality standards are to be met in all streams and rivers.
