Where Did Water Come From & How to Conserve It?

Water. You turn on the faucet, and out it comes. But where did water on Earth originally come from? Some scientists believe oceans may have been formed (about 8 million years after the formation of planet Earth itself) by water dumped from passing comets. The recent discovery of a comet containing water with a similar chemical composition to the water all around us on Earth has given support to that theory.

Hartley 2, a comet about 1.25 miles long, contains ice with the same D/H ratio (the proportion of “heavy hydrogen”) as water found in oceans here on Earth. It’s the first time that Earth-like water has been detected in a comet. Hartley 2 probably comes to us from the Kuiper Belt, a sector of space about 30 times Earth’s distance from the sun. Six other comets studied by the scientists contained water with a different composition, and probably originated in the Oort Cloud, about 5,000 times farther away.

Water Guide

Canada contains one-fifth of the world’s fresh water resources, however, only 7% of that water is renewable. In Canada we consume more water per person per day than most other countries in the world. In B.C., we use about 490 litres of water per person per day, more than 150 litres per day above the Canadian average.

With factors like pollution, high rates of consumption, climate change, and water privatization putting increasing pressure on our fresh water and energy resources, British Columbians need to get serious about water use. B.C. has developed a provincial target of improving water efficiency by one-third by 2020. We all need to do our part – or more, to protect our fresh water resources for generations to come.

BC Hydro Tips On Saving Water:

Run Full Loads

Your dishwasher and laundry appliances use a lot of energy and water, and contribute significantly to your utility bills.

Use A Low-Flow Showerhead

Hot water can account for a substantial portion of a household’s total energy costs.

Identify & Fix Leaks

A leaky faucet can waste 11,350 litres (2,500 gallons) or more every year.

Save Water In The Kitchen

Reducing the amount of water you use helps protect freshwater resources, reduce the need for water sanitation infrastructure and save you money.

Save Water In The Bathroom

There are many opportunities to reduce water use in your bathroom.

Save Water Outdoors

Being water wise outdoors can save hundreds of litres of water each year.
