Water Service Options in Calgary

Unlike electricity or internet services, water service in Calgary is fully municipal — meaning there is one provider and no competition, but homeowners still have important responsibilities and billing considerations.

Who Provides Water in Calgary?

The City of Calgary Water Services department provides:

• Drinking water supply

• Wastewater (sewer) service

• Stormwater drainage services

All residential properties connected to city infrastructure receive water through this system.

There are no private residential water utilities within Calgary city limits.

Where Does Calgary’s Water Come From

Calgary’s drinking water comes from two primary river systems:

• The Bow River

• The Elbow River

Water originates from snowpack and glaciers in the Rocky Mountains before being treated at municipal treatment plants.

Why this matters to homeowners

• High-quality mountain-fed water supply

• Reliable long-term water availability

• Moderately hard water, which can lead to mineral buildup in appliances over time

How Water Gets to Your Home

Every serviced home typically has:

• A water service line connecting the home to the city main

• A water meter installed inside the property

• Interior shut-off valves for emergencies

Water moves through Calgary using pumping stations and elevated storage reservoirs that maintain consistent pressure citywide.

How Water Billing Works

Water is metered, meaning you pay based on usage.

Bills are typically issued monthly.

Charges included

Your bill usually combines:

• Water consumption

• Wastewater treatment charges

• Stormwater fees

• Fixed service and infrastructure charges

Even with low usage, base service fees still apply.

Wastewater charges are calculated using water consumption as an estimate of sewer output.

What Happens When You Buy and Move Into a Home

When ownership changes:

• Your real estate lawyer notifies the City of Calgary.

• Utility accounts transfer to the new owner.

• Meter readings determine buyer/seller adjustments.

• New billing begins after possession.

Important:
Water charges are tied to the property and are normally settled during closing adjustments.

Homeowner Responsibilities

You are responsible for:

• Interior plumbing maintenance and leaks

• Frozen pipe prevention

• Private water service line repairs on your property

• Maintaining access to the water meter

• Monitoring consumption for unusual increases
