Guelph Center for Urban Organic Farming Final Design
This paper presents a low impact, energy eﬃcient designed rainwater harvesting and irrigation system for the Guelph Centre for Urban Organic Farming at the University of Guelph. The system collects water from the roofs of nearby residence buildings, stores it and delivers it to the site as needed. An analysis showed that suﬃcient water is provided for summer and winter months by using 3068 m^2 of roof area with a 45 m^3 underground storage tank and a 136 m^3 irrigation pond. With these parameters drought would rarely occur at the farm and if it did occur it would last only a short period. Two solar panels that produce a total of 160 W are used to power the pump. The total cost of the system is $65 000.
