Design and build a rainwater harvesting system — from roof catchment and gutters to storage tanks, filtration and maintenance — to keep water flowing year-round.
Rain is a free, clean resource falling on your roof. This course teaches you to catch it, store it and use it safely — for gardens, livestock, household needs and, with the right treatment, even drinking. Rainwater harvesting is one of the oldest and simplest ways for households, schools and communities to supply their own water.
Across five modules you will learn how to size a system from your rainfall and roof area, choose catchment and guttering, select and protect storage, treat water for different uses, and maintain the system so it lasts. Practical calculations and checklists make it ready to build.
