RainCycle

Developed as a decision-making assistant, RainCycle is a Microsoft Excel spreadsheet that focuses on the hydraulic simulation of Rainwater Harvesting Systems (RWH), such as the costs of construction, operation, maintenance, and decommissioning. It covers residential, industrial, commercial and public buildings.
The downloaded package includes the standard and advanced version of RainCycle, in addition to in-depth help documentation and tutorials (for a junior school. These Excel spreadsheets can be copied to your computer and used as templates when designing your own hydraulic simulation systems. Just make sure to keep the original files untouched by saving your own models as new files or by creating backups.
RainCycle features optimization programs for storage tank sizes and cost savings, as well as a simulation for the harvesting system (up to 100 years, including yearly expenses and detailed results). It can take into consideration all costs, automatically generate reports, check for errors, and use any currency you define.
The hydraulic modules cover rainfall profiles, catchment surface, rainwater filter, storage tank, pump, UV unit and water demand, while the analysis modules are available for project and whole life cost details, tank size, saving and other optimization modes, along with system, sensitivity and Monte Carlo simulation analysis.System requirementsIBM Compatible PC
