Some city water treatment facilities combine storm water and sanitary sewage systems. During heavy storms, these treatment facilities may be overwhelmed with water, and untreated storm water mixes with sewage and flows directly back into the streams and rivers where treated water usually returns. What might be the best way to address this problem?
A) do not collect rainwater in storm sewers and let it just accumulate on the roads
B) collect and treat storm sewer and sanitary sewage systems separately
C) drain the sewage system onto a field near the stream or river
D) use the excess sewer water as a source of water for the city
