Essential Rainwater Harvesting Tool
The feasibility stage of designing a rainwater-harvesting system is about evaluating your project and selecting the size(s) of your roof and storage containers to best meet your needs for the least possible cost.
In Essential Rainwater Harvesting: A Guide To Home-Scale System Design (book), we provide you with the step-by-step instructions and templates to build your own simple rainwater harvesting calculation tool, using any spreadsheet software.
However, our Essential Rainwater Harvesting Tool is a pre-built spreadsheet tool that contains beautifully formatted tables, the formulas and logic presented in the book, plus a substantial number of more advanced features. It is pre-programmed and ready-to-go.
