Overview
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
Greensferry
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.
