In this paper we present a new system for gathering and utilizing rainwater for uses in an industrial capacity. The main idea is to capture, transport, store, and lter rainwater and feed cooling systems within the factory. The design consists of four major components: PVC piping for transportation, a 10,000 Gallon water tank for storage, membrane and UV filtration units and a pump. The design was simulated and tested and results show that the system will have a cost of $23,000 including installation, which translates into a payback period of 18 months.

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.
