City of Calgary - Water Efficiency

Calgary is big city on two small rivers, the Bow and the Elbow. We depend on our rivers to provide a stable supply of water for more than 1.2 million people living in the region and the businesses that work here – numbers that continue to climb.


In 2005, the City developed and approved the30-in-30 Water Efficiency Plan, demonstrating our commitment to sustainable water management.

Our goal is to hold withdrawals from the river steady at the 2003 baseline level of 212.5 billion litres, despite a growing population. To do this, the City committed to reducing its water consumption by 30% over 30 years.

Water Forecast Calgary

Our rivers are under increasing pressure from a growing population, development and extreme weather ranging from intense rainfall to hotter, drier summers and, shorter, more extreme winters.

Calgary's Water Use

Calgarians have been working hard to protect our rivers by using and wasting less water and we’ve made great progress, but there is work ahead.

In 2018, our total per capita water use (including residential and business customers) was 362 litres per capita of water per day (LPCD), well on track to achieving our target of 350 LPCD.

Total Water Use by The Community

The figure above shows water used by residents, businesses and institutions as well as water lost through leaks, unaccounted for or not billed. This total is then divided by the number of people living in Calgary.

  • Keeps our rivers healthy

  • Builds a culture of sustainability and strong communities
