Sewer separation is the construction
of new sanitary or storm sewers within a combined sewer
service area. The existing sewers will then serve as either
sanitary or storm sewers, depending upon the design intent
of the newly constructed sewers. In a separate system, stormwater
is conveyed to a storm water outfall for discharge directly
into the receiving water. The sanitary flow is typically
piped to a treatment plant for screening and disinfection
before being discharged.
Under the current Authorized CSO
Remediation Plan, the City will fully separate the
and McDaniel CSO Basins
and the Stockade
Sub-basin (Custer CSO Basin). This plan will increase the city's total separated area
from 85% to about 90% and eliminate two CSO facilities
and one CSO regulator.
