Portland CSO Basin
Home Public Input Portland CSO Basin
Basins are a key part of achieving safe, clean waterways
Rainwater can enter the sewer system during rain events and cause a mixture of sewage and rainwater to flow untreated into our waterways. Proposed and existing storage basins—throughout our city—are designed to retain the mixture of rainwater and sewage until the rain subsides, and then gradually release it back into the sewer system for treatment.
Portland CSO Basin
The covered underground Portland Storage Basin will offer the Ohio River protection from combined sewer overflows.
