A rain water collection system for the Guelph Centre for Urban Organic Farming(GCUOF) has been designed to meet the irrigation demands of the farm 9 out of 10 years. The design uses no municipal services or electrical energy and collects rain water on site using an elevated catchment ”funnel” along the southern edge of the farm. Drip irrigation is used to water the crops. Water is stored during the winter months in the greenhouse for irrigation. Best farming practices for water conservation are assumed to be used along with dilligence on the farmer's part. The initial cost of the system is estimated to be $26000.


Created in fulfillment of the course requirements for ENGG*3100 Engineering and Design III. This course combines the knowledge gained in the advanced engineering and basic science courses with the design skills taught in ENGG*1100 and ENGG*2100 in solving open-ended problems. These problems are related to the student's major. Additional design tools are presented, including model simulation, sensitivity analysis, linear programming, knowledge-based systems and computer programming. Complementing these tools are discussions on writing and public speaking techniques, codes, safety issues, environmental assessment and professional management. These topics are taught with the consideration of available resources and cost.
