Abstract
This paper presents the design of a rainwater harvesting system for Linamar Corporations CAMTAC plant. The main purpose of the design is to decrease municipal water costs by supplying rainwater for manufacturing processes. The system consists of two underground concrete storage tanks placed inline with the existing stormwater management system at the plant. After storage, the system uses a pump and pressure tank to deliver water throughout the system. Water treatment consists of two cartridge filters and an ultraviolet disinfection unit prior to entering the existing reverse osmosis unit. The storage tank level was simulated using historical precipitation and water demand data. The results showed that the design will allow for annual savings of approximately $13,000 in municipal water costs with a payback period of 2.3 years.
