Water Submetering

Water submetering brings the same fairness and transparency to water billing that electricity submetering provides for power.

Why Water Submetering Matters

Water costs are rising across Ontario. In buildings without individual water meters, costs are typically split equally regardless of usage. Water submetering addresses this by measuring each unit's consumption individually, encouraging conservation and ensuring fair billing.

Conservation Impact

Studies suggest that water submetering can help reduce water consumption in multi-residential buildings. When residents can see their own usage and pay based on what they consume, they tend to adopt more water-efficient behaviours.

How It Works

Individual water meters are installed on each unit's water supply lines. These meters record consumption data that is used for billing. Residents receive clear statements showing their water usage and charges. The approach is similar to electricity submetering but applied to water consumption.

Frequently Asked Questions

Is water submetering regulated in Ontario?

Water submetering in Ontario is subject to municipal bylaws and provincial regulations. Requirements vary by municipality. Voltage Vision ensures all water metering installations comply with applicable local regulations.

Can water submetering be combined with electricity submetering?

Yes. Many buildings benefit from both electricity and water submetering. Installing both at the same time, particularly during new construction, is the most efficient approach.
