Water Rates

The Water, Wastewater and Stormwater program is self-sustaining . Revenue comes from billing residents for water use.

You are charged for water use based on your water meter reading.  You receive a bill for your water use from the City’s billing agent, Alectra Utilities (formerly Horizon Utilities). If you have questions regarding your water bill or payment options, contact Alectra Utilities (formerly Horizon Utilities), Billing at 905-522-9200 or visit Alectra Utilities (formerly Horizon Utilities).

When ownership of property is transferred, the buyer’s real estate lawyer must contact Alectra Utilities (formerly Horizon Utilities) at 905-522-9200 to:

  • provide the relevant property transfer information
  • request a final actual water meter reading, not an estimate

This ensures all parties are aware of any outstanding water and wastewater charges and/or compliance issues with Hamilton’s Water Works By-law No. R84-026, such as the replacement of obsolete equipment.­

If a final water meter reading is not obtained, all ou­­­tstanding charges and compliance issues with Hamilton’s Water Works By-law No. R84-026 are transferred with the property and become the new property owner’s responsibility.

How much will my bill increase?

An average household consuming 200 cubic metres of water annually will pay an additional $29.70 per year or $2.48 each week. This represents a 4.11% increase from 2019.

How do we compare to other municipalities?

Hamilton’s water and wastewater/storm rates are among the lowest in Ontario. Hamilton has the second lowest water costs at $722 for 200 m3/year amongst the cities in our region as shown below:


Why do rates keep increasing?

Water and wastewater budgets contain fixed costs that do not change in direct proportion to water consumption. The cost to distribute, collect and treat municipal water and wastewater throughout the City remains relatively constant, regardless of the volume actually consumed by all residents.

The largest portion of your bill is used for capital renewal and expansion of the City’s overall water/wastewater/stormwater infrastructure that has a replacement value of $10 billion. Aging City infrastructure becomes more costly to operate, maintain and replace with over 20% of the City’s water and sewer mains being more than 80 years old.
