Four Pillars

The sanitary sewer system carries sewage from homes and businesses to the waste water treatment plants. Over time, pipes that make up this system have developed cracks and leaky joints that let rain water into the sanitary sewer, causing it to fill up beyond its capacity and overflow into rivers or back-up into basements. Foundation drains that connect directly to the sanitary sewer also contribute to the problem of rain water getting into the sanitary sewer.

Blueprint Columbus will stop rain water from entering the sanitary sewer system through lateral lining, roof water redirection and a voluntary sump pump program. That rain water will be directed to green infrastructure so it can filter through layers of stone, soil and plants before it slowly releases into the storm sewer system that empties into our rivers and streams.
