Water & Wastewater
Beginning on October 22, 2012 the City of Lebanon began purchasing water from the Greater Cincinnati Water Works (GCWW). There were several key reasons for making this decision.
In 2001 the City of Lebanon Water Department completed a Water Master Plan. One key element of this Plan was to determine if there was enough water available in the aquifers to meet the future water needs of Lebanon. After several extensive explorations it was determined that the aquifer would not be able to supply the future daily water demands generated from Lebanon’s projected residential and commercial water needs.
There was core water-supply infrastructure that was in need of replacement. The City’s North Water Treatment Plant had reached the end of its useful life and would require a full replacement and expansion to meet future water treatment requirements. Two of the eight production wells were over 60 years old and were beyond their useful life. Due to new OEPA Well Site Construction Standards, no new wells would be allowed to be installed on that site if those wells were to fail. Replacing these water supply and treatment facilities would have required a significant financial investment and increased operating costs.
Improved Water Quality
The water provided by GCWW is softer than the water Lebanon provided through its treatment process. Lebanon’s water hardness was 475 mg/L while that of GCWW is 150 mg/L. Lebanon was supplying water with a fluoride content of 0.25 mg/L. Water provided by GCWW will have a fluoride concentration of 1.0 mg/L.
GCWW Treatment Process
Lebanon now receives its water supply from GCWW’s Miller Plant on the Ohio River. With the Ohio River as its source the Miller Plant has an unlimited amount of water it can supply to its users. Water is diverted from the Ohio River into a pre settling basin where settling aids are added to remove most solids. The water then flows into another settling basin where it is prepared for final treatment. This treatment consists of filtration through sand and gravel filters to remove any remaining particulate matter. The filtered water then flows into the Granular Activated Carbon (GAC) basins for removal of organic materials. GCWW is a pioneer in using GAC for the removal of organic materials and their process is copied in major cities around the world. After GAC treatment fluoride and chlorine are added to the water. The water then flows through an ultraviolet system for further disinfection. The water is then pumped into the distribution system.
GCWW constructed a pump station in the industrial park to move water into the Lebanon owned and operated water distribution system.
