Broadview Heights Water Hardness & Quality Report (2026)

The Cleveland Water Department serves Broadview Heights, Ohio, drawing water from Lake Erie — the region's primary surface water body. Treatment occurs at the Division Avenue Water Treatment Plant and other facilities, using screening, coagulation, sedimentation, filtration, and chloramination to produce safe drinking water. Some areas supplement with groundwater from local wells, creating a mixed supply. The system delivers to approximately 20,000 residents in Broadview Heights and nearby communities within Cuyahoga County.

Water originates from the Lake Erie watershed, encompassing drainage from Ohio's glacial plains and the Cuyahoga River basin. Underlying Devonian shale, limestone, and dolomite formations — including the Berea Sandstone and Chagrin Shale — interact with surface runoff, imparting minerals to the supply. Glacial aquifers in unconsolidated sand and gravel deposits contribute in some locales. Silurian and Devonian carbonate rocks dissolve calcium and magnesium ions into the water, yielding a hard supply with notable mineral content from ancient sedimentary formations.

Hard water promotes scale buildup in pipes, water heaters, dishwashers, and washing machines, reducing efficiency and lifespan. Faucets and fixtures may develop mineral stains, and soap lathering is less effective, leading to scum in showers. Regular maintenance such as flushing water heaters and cleaning aerators is advised. A water softener is recommended to mitigate these effects and protect appliances. Cleveland Water meets all EPA standards — pH typically 7.5–8.5 — with robust lead and copper rule compliance through corrosion control. No recent PFAS exceedances reported; occasional iron/manganese discoloration is addressed by flushing hydrants.
