Treatment Plant / Laboratory Tours


The 45-minute bus tour of the plant will cover the primary and secondary operations, solids process, energy recovery facility and outfall where approximately 156,000 gallons of purified wastewater is discharged into the Ohio River each minute. Tours depart every 15 minutes but fill up quickly – we recommend that you get your tickets at the tour ticket booth when you arrive. Event registration does not include tour tickets.


A 30-minute walking tour of the Lab provides an overview of the types of tests performed and the equipment used for analytical research. This tour is designed for both technical and non-technical audiences and is offered at 10 a.m., noon, 2 p.m. and 3:30 p.m. No tickets are required but space is limited.
