The City of Olmstead’s Proficiency in Stormy Weather


Olmstead is putting in place an impressive $39 million capital improvement program.  Along with the ongoing maintenance and repair procedures, the North Olmsted team has flood management under much better control.  North Olmsted’s 37,000 residents are served by a separate sanitary sewer system that runs for 159 miles beneath this Cleveland suburb. Sewer lines, most of them installed well over forty years ago, consist of vitrified clay pipe ranging in diameter from 8 to 42 inches. The system contains 2,800 manholes and approximately 900 hydrants.  Five pumping stations power the system. Four are positioned around the city in relation to a natural divide that passes through the area, and all four pump into a main sewer line south of Lorain Road. A fifth station was added more recently to serve a new commercial development.

Wastewater flows to a conventional activated sludge treatment facility, designed to handle average daily flows of 5.5 mgd.  Located near the Lake Erie shoreline, North Olmsted is used to stormy weather. Rainfall in an average year is just over 43 inches. Annual snowfall exceeds 60 inches. Sudden storms can dump as much as 4 inches of rain in just a few hours.  One of the ways the City has addressed this concern is by installing equalization tanks to store sewer overflows and feed them back into the system during dryer weather.
