Rainwater Harvesting - Replacement to Municipal City Water
The rainwater harvesting system designed for Linamar Corporation provides 38 m3 of water per day and reduces the city water consumption. Sensitivity analysis was performed using the tank cost and the daily consumption which is affected by the amount of area used. The optimum range was between 30 m3 to 40m3 and a 38m3 tank was selected to meet high demands for some months. The system meets 66% of the total demand while the remaining is fulfilled by City water. Budget for this project is kept under 30K, which provides a payback period of 2 years and a return on investment of 61% in the rst year. Various cost savings in this project includes reduction in water bills, softening costs and storm water discharge costs.. . .
