At the Eco Dairy, publicly accessible commercial installation, Barr Plastic installed a system that harvests rainwater to irrigate a green roof, where goats graze & frolic. The average rainfall is 60 inches per year, and is stored in a green 3,000 US Gallon Norwesco tank, and distributed by a 3/4 HP Leader pump to supply sprinklers. It's located at 1356 Sumas Way, Abbotsford, British Columbia, Canada. Eco Dairy is the first educational dairy farm in Canada which features the latest sustainable technology. Their phone number is 604-557-5481. For more information on the installation, contact Barr Plastics.
