We only seem to recognize the value of water when it becomes scarce in times of drought and with the changing seasons. Yet we each dirty and waste 45 liters of this precious resource every day just to flush away our excrement. As the need to save water becomes ever more urgent, Jardin d’Aisance offers an alternative to conventional wastewater treatment methods.
Urine is a potentially valuable resource that can be used to revitalize and fertilize the soil. Thanks to a low-tech system of filters and microbes, urine—which cannot be used in its pure form—is stabilized and transformed into an odorless fertilizer known as pitribon. Just 15 liters of urine can produce enough fertilizer to treat a garden the size of the public toilets in Parc Louis Bourget for an entire week. With its young forest ecosystem, Jardin d’Aisance is proof that this urine-based natural fertilizer can nourish and sustain woodland gardens.
