What changed
Columbus is not framing the 2026 increase as a one-off inflation adjustment. The city points to major long-term growth and capacity needs, including a fourth water plant expected to cost more than $2 billion.
For commercial properties, the 18% water increase is the headline, but the 8% sewer increase matters just as much because many businesses pay sewer charges based on metered water volume.
Commercial impact model
A property spending $10,000/month on combined water and sewer before the adjustment should not budget a simple 8% blended increase unless it knows the water/sewer split. If 55% of the bill is water and 45% is sewer, the blended increase is roughly 13.5%, or $1,350/month.
At that usage profile, annual exposure is about $16,200 before any demand growth, stormwater adjustment, connection-fee changes, or service-size charges.
What operators should do
Columbus businesses should separate the bill into water, sewer, and stormwater line items, then calculate the effective blended increase by account. Multi-meter campuses and industrial users should do this meter by meter.
If the property is in a high-use category, reducing metered volume is the most direct lever because it lowers both water commodity charges and sewer charges tied to water use.
