Rainwater Harvesting Philippines
Rain water Filtering system provides a way to clean and filter water debris from the roof. Rainwater is free from chemicals and chlorine so it is safe and smart to collect. This system will pay itself overtime since the cost of water is very expensive.
Common Applications of Rainwater
- Watering Green wall / Vertical garden
- Watering Green roofs
- Car Cleaning
- Laundry
- Flushing Toilet
- Drinking (Need additional Filters)
- Showering (Need additional Filters)
Rainwater Harvesting Procedures

Step 1: Water flows from the roof

Step 2: Water flows from roof to rain gutters

Step 3: Water flows to the rain water harvesting filter

Step 4: Centrifugal force to seperate the debris and small particles

Step 5: Dirt goes down and clean water goes to tank

Step 6: Clean water stored in water tanks ready for use
