A sustainable solution for your toilet

Water is a precious and vital commodity. However, in our households, the largest proportion of drinking water is used to flush the toilet and use the washing machine. Using rainwater for your toilet could save a huge volume of drinking water each year. As the toilet flush is not used as a source of drinking water, this is a practical and sustainable alternative.

Before using rainwater, seek specialist advice and check with the manufacturers of your household appliances to ensure they are suitable for this. Additional installations may be required.
