iKapa Concrete Rainwater Harvesting Tanks

How does water harvesting work?

An iKapa tank is fitted to your down pipe from your roof, and falling rain enters the tank through a filter screen which removes leaves and other debris. A pump is fitted to the water tank to pump cool stored water to its desired use. Watering your lawn/garden, washing your car, top-up your pool, hose your driveway and so much more...
