Water Treatment Tabs
Cleveland Water has a comprehensive treatment process—amongst the finest in the country—involving screens to remove large debris, rapid mix, flocculation, sedimentation, filtration, and disinfection.

Raw water is drawn from Lake Erie through intakes located approximately 3 miles off shore where the water is cleaner.
Screens are used to remove fish, shells and other large debris. Pumps propel water throughout the treatment process.
Powdered Activated Carbon is added just before rapid mix to help eliminate unpleasant odors and tastes. Alum is then added to help small particles bind together and the water is mixed at high speed.
Mixing speed is gradually reduced to allow the Alum to form clumps which can be more easily removed.
The clumps sink to the bottom of the sedimentation basins, trapping larger organic materials.
Water is filtered through sand and coal removing smaller organic particles not captured during the sedimentation process.
Chlorine, which kills bacteria and viruses, is added to disinfect the water. Orthophosphate and fluoride finish the treatment process.
Plants, towers, tanks and 5,300 miles of water mains distribute water to more than 427,000 homes and businesses in Cleveland Water’s service area.
|Powdered Activated Carbon||Added to the water for absorption of organic material that can cause unpleasant tastes and odors|
|Alum||Added to the water as a coagulant to help small particles stick together so that they can be removed more easily|
|Chlorine||Added to the water for disinfection. It must remain in contact with the water for prescribed periods of time to ensure that bacteria, viruses, and other microbes are killed.|
|Fluoride||Added to the water to promote good dental health|
|Orthophosphate||Added to the water to inhibit lead corrosion of plumbing fixtures|
|Potassium Permanganate||An oxidant that is added to the water to condition it so that coagulation and filtration can more effectively remove particulates|
Water Treatment Unit Processes
|Screens||Remove fish, shells, and other large debris|
|Pumps||Propel the water through the treatment process at a controlled rate|
|Rapid Mix||Quickly distributes treatment chemicals through the water|
|Flocculators||Mix the treatment chemicals with the water at a controlled rate in three stages of decreasing energy to clump the smaller particles together|
|Sedimentation Basins||Water moves very slowly through the Sedimentation Basins to allow large particles to settle down to the bottom and be removed from the water.|
|Filters||Remove fine particles from the water|
|Finished Water Reservoir||Disinfection takes place in the Finished Water Reservoir before water is distributed to customers.|
