About this area's water

Did you know
- Lebanon hasn't treated a drop of its own drinking water since October 2012, when city and Cincinnati officials turned a valve together to start a 40-year, up-to-7-million-gallons-a-day wholesale deal.
- The pipeline that made that possible -- 40,000 feet of water main plus a new pump station -- was built starting in fall 2010 and finished three months ahead of schedule.
- Lebanon tap water is a blend: about 88% Ohio River water filtered through granular activated carbon at Cincinnati's Miller plant, about 12% groundwater lime-softened at the Bolton plant from a Great Miami Aquifer well…
- GCWW was the first water utility in the nation to use granular activated carbon with on-site reactivation, and it added UV disinfection after sand filtration and GAC.
- Buying its water didn't make Lebanon a bystander: the city still owns and maintains about 110 miles of pipe, four booster stations and four water towers for roughly 7,300 accounts, and ran over 1,000 of its own water…

GCWW's supply is a blend of Ohio River surface water treated at the Richard Miller Treatment Plant (about 88% of GCWW's water) and groundwater from the Bolton Well Field…

Supply stress
Lebanon's source is not stressed. It draws on GCWW, which serves more than 1.1 million people, produces about 133 million gallons a day and can treat up to 280 million, from the Ohio River plus the Great Miami Aquifer. Lebanon's own exposure is contractual and structural rather than hydrologic: its wholesale agreement is capped at 7 MGD…
Sewers

The City of Lebanon operates its own sanitary collection system and wastewater treatment plant. The collection system is more than 100 miles of sanitary sewer main, 14 miles of sanitary force main and seven pump stations. Aeration improvements at the WWTP and an update of the Sewer System Master Plan are on the 2026 and 2027 council goal…
