Collecting Rainwater for Your Garden
More and more people are mindful about not wasting water and are choosing to collect rainwater that can be used in their flower or vegetable garden.
Why collect rainwater?
Although water shortages are not yet a problem in Québec, efforts are being made to raise awareness about the importance of reducing our water consumption. According to Environment Canada, every Quebecer uses an average of 400 litres of water per day for personal consumption, including 30% for outdoor use in the summer. Using rainwater in a vegetable or flower garden to wash your car or even to fill a swimming pool are ways to reduce our consumption.
What are the advantages?
Recovering rainwater helps limit the volume of water that needs to be treated by filtration systems, it protects groundwater and reduces the costs required to process the water. It also reduces risks associated with flooding and ensures an additional water resource in the event of a shortage.
How to collect rainwater
There are several solutions available, many of which are quite inexpensive. You can even build one yourself using a recovery, storage, filtration and distribution system.
- The recovery of water can be done by connecting the gutters to the storage solution;
- The storage of water requires a simple above-ground plastic barrel that has a capacity of approximately 200 litres. For larger gardens, you can bury a prefabricated concrete (or plastic) tank with a capacity of 2,000 to 10,000 litres;
- The filtration is done with a simple system that removes all of the large impurities;
- The distribution is done through a valve or pump.
If you have more specific needs, such as a swimming pool, it’s best to consult a professional. You should also know that if you sell your home one day, the water recovery system will be considered an added value.
