    Aquarius Water Treatment

    The Aquarius Water plant represents years of planning to provide the citizens of western Lake County with a water supply and distribution system. The 20 MGD facility services customers from Eastlake, Lakeline, Timberlake, Wickliffe, Willoughby, Willoughby Hills and Willowick. It has improved water pressure for individual homeowners and provides an adequate supply of water for fire protection.

    Interesting Facts:

    • Before Aquarius was built, western Lake County was supplied with water from the City of Cleveland.
    • In 2008, the Aquarius Treatment Plant produced an average of 9.7 million gallons per day.
    • Currently, the plant provides water to 80,000 residents in seven Lake County communities.
    • Hardness of water: 114 mg/L or 7 g per gallon.
    • Pressure of water coming from plant: 80 pounds

    Water Treatment Process

    Water Collection/Intake

    The initial step in the water treatment process is the collection of the water. The water that some of us will eventually drink is collected though a pipe 60 inches in diameter about 3,000 feet off the Lake Erie shore. The water in this pipe flows to the raw water pump station. When the water reaches the raw water pump station, the water in the pipe goes through two traveling screens, which remove debris and/or other objects from the water. After the water has traveled through the screens, it streams into two 61,500-gallon raw water clear wells. From inside the containers, the water is pumped out to the treatment plant by five vertical turbine pumps.

    Rapid Mix Tanks

    When the water reaches the treatment plant, it is separated into two 5,000-gallon rapid mix tanks. At this point, the chemicals can be added to the water to control odor, taste, and pH levels.

    Flocculation Tanks

    The water is then sent to the flocculation tanks, where a large paddle slowly moves around the water to make sure that the chemicals previously added complete their chemical reactions. It is in this tank as well, that the different particles and sediment floating around the water clot together and settle to the bottom of the tank. Once the chemical reactions are completed in the flocculation tanks, the water flows into the four settling basins.

    Settling Basins and Sludge Thickeners

    Since some of the waste on the bottom of the tanks is already settled, it is collected and sent to the sludge thickener for disposal. When there is enough sludge to dispose of, it is removed from the two 60,000 gallon sludge thickeners and taken to the Lake County Gary L. Kron Water Reclamation Facility in Mentor.

    Filtration

    As the water continues on its journey to our faucets, six double cell high rate filters eliminate the remaining sediments in the water. The water is filtered through coal and sand filters, which produce the final product: clean drinking water. An under drain collection system takes the water to its final resting place before it is distributed. Sometimes though, the water that has just been finished is used in a backwashing process, where the water is pumped backwards through the filters to remove any contaminates. Water used to backwash the filters, is then sent through the treatment process all over again.

    Finished Water Storage

    Finished water is passed through two 375,000-gallon storage tanks, two clear wells and two water chambers before the chlorine and caustic soda (chlorine further disinfects the water and the caustic soda balances out the pH) are added. Once these chemicals are added to the water, the fully treated water is pumped out to the distribution system by five vertical turbine pumps, where it soon can reach a sink near you.
