A residential system that recycles greywater (water from showers, baths and sinks) or harvests rainwater can lead to water savings of about 146,000 litres a year for a 4-member family that uses appliances regularly. That’s enough to fill 3 aboveground swimming pools. Installing these 2 systems will reduce annual water consumption by about 33%.

Our recommendations :

1. Rainwater harvesting systems direct the water from the roof gutters into tanks for storage. It can then be reused for activities that do not require potable (suitable for drinking) water, such as watering the garden, washing the car or supplying toilets. Water that is reused for toilets must be filtered and treated to prevent the build-up of bacteria, which would have an impact on resources and water quality. Harvesting and using rainwater can save water and reduce the pressure on public utilities.
2. Creating a rain garden is another way to re-use water: the gutter downspouts are directed to a depression located at least 4 metres away from the foundation and filled with indigenous plants that can withstand drought and occasionally flooding. The water must be able to filter through quickly (24 to 48 hours) to avoid creating a breeding ground for mosquitoes. You’ll need the help of a professional to create a garden of this type.
