Blueprint Columbus is an exciting new opportunity that is being explored by the City of Columbus. Its focus is eliminating sanitary sewer overflows while also investing in our neighborhoods and our local economy.

Blueprint Plan Cover

Blueprint Columbus was submitted to the Ohio EPA on September 15, 2015. This plan has many advantages over the City’s original Wet Weather Management Plan: it's faster and cheaper; it’s greener; it’s more affordable; it’s more innovative; it’s better for our neighborhoods and our local economy; and it’s what our community wants.

Understanding Our Sewer System There are three types of sewers:
• Combined sewers carry both sewage and rain water to wastewater treatment plants
• Separate sanitary sewers carry sewage from homes and businesses to wastewater treatment plants
• Storm sewers convey rain water from streets, rooftops and parking lots to nearby streams - learn more

Water Gushung Manhole

An Old Problem Our sanitary sewer system works well most of the time, but rain water and snow melt can seep into the system and overload it. When this occurs, the amount of water entering the sanitary sewer system exceeds the system’s capacity to hold it. - learn more

Town Street Green Infrastructure

A New Approach The City of Columbus is in the process of developing a new approach to eliminate sanitary sewer overflows. Instead of simply storing excess water that seeps into the sanitary sewer system when rain falls and snow melts, Blueprint Columbus will address the source of the problem. - learn more

Four Pillars

Four Pillars There are four pillars that make up Blueprint Columbus: lateral lining, roof water redirection, a voluntary sump pump program, and green infrastructure. Lateral lining, roof water redirection and sump pumps keep rain water out of the sanitary sewer system and green infrastructure protects the quality of water in our rivers and streams.

Clintonville Area Project

Clintonville Area Project The City is investigating the best method for eliminating the sanitary sewer overflow into Adena Brook in Whetstone Park. This project will reduce the amount of rain water that makes its way into the sanitary sewer, overburdening the system and resulting in an overflow - learn more
