Product Description
The 10000 Litre Carat Garden Comfort Rainwater Harvesting System from GRAF is a garden watering system built around a Carat XL underground tank. It suits large gardens, nurseries and equestrian yards, giving you a large store of free rainwater that comes out of a tap or hose at the push of a lever.
As a guide, British Standard BS 8515 suggests a tank of around 5% of the rain your roof collects in a year. On an average UK roof, that therefore makes the 10000 litre tank a good match for a roof area of roughly 335 square metres.
How the Carat Garden Comfort System Works
Rain from your roof runs through the basket filter on its way into the tank, which removes leaves and debris. As a result, the stored water stays clean and the overflow syphon skims off floating matter each time the tank fills.
The Divertron X 900 submersible pump sits inside the tank and draws water through a floating intake just below the surface, where the water is cleanest. Because the pump is pressure activated, it starts as soon as you open a tap or turn on a hose and stops again when you close it.
Key Benefits
- Free rainwater for gardens, lawns, vegetable beds and washing down
- Pressure activated pump, so there are no switches to remember
- Pump and pipework hidden below ground, so the garden stays tidy
- Rainwater is soft and free of chlorine, which is better for plants
- Reduces reliance on metered mains water and hosepipe bans
