Find leaks, prevent floods, manage water use
Your home or building has a City-owned water meter that measures the total amount of water used on your property. The City uses that meter for billing purposes.
A water sub-meter lets you measure water consumption by the minute so you can find leaks, inefficient plumbing fixtures and other water-wasting activities. When you understand how water is being used, you can fix problems, reduce consumption and save money on your water bill.

About water sub-meters
Most sub-meters let you monitor water use from a smartphone or computer. The City will not have access to the data from your water sub-meter. Some will shut your water off automatically if a possible leak is detected, preventing damage to your property. Talk with your insurance provider to learn about possible discounts for customers who own a water sub-meter.
Water sub-meters are available online at select hardware stores. The City of Guelph does not endorse retailers, products or services.
