About this area's water
Did you know
- Northwood gets its water two different ways depending on which side of town you live on: the west end from the City of Toledo, the east end from Oregon by way of this district.
- The water arrives from a crib sitting completely submerged 16 feet down and 1.5 miles off the Lake Erie shore, drawn through a 48-inch line to a pump station near Anchor Point Marina, then pushed 5 miles through 36-inch…
- Treatment starts before the water has gone anywhere: potassium permanganate is dosed right at the lake intake to stop zebra and quagga mussels from colonizing the conduit.
- This district resells water but treats none of it - the entire Waterline 200 system is a distribution network hanging off one 1963 municipal plant in a neighboring county.
- Millbury, one of this system's two anchor towns, was hit by an EF4 tornado in 2010.
History4

Treatment & pressure
How it is treated
The district treats none of its own water - Waterline 200 buys finished water wholesale from the City of Oregon. Oregon's plant (built 1963, expanded to 16 MGD, 667,000 gallons per hour) draws from a fully submerged intake crib in Lake Erie near Reno Beach, 1.5 miles offshore in 16 feet of water…

Typical household bill about $45 a month for water.
The district publishes an average bill rather than a plain volumetric rate. For 2026 its rates page puts the average residential customer using 7,500 gallons a month at $45.34 for…
