An alternative to a rain barrel: more rainwater, a natural fit for your garden.
After a shower, there is plenty of water. But when your plants need it later, a small rain barrel may already be empty. Want more in reserve without a large barrel in view? Give that rain a place along the edge of your garden.
Collecting and using rainwater in the garden
A lot of rain in one shower, but your plants need water later? Through your roof and downpipe you collect part of it in a water butt or rainwater wall. You keep it for plants, borders and pots, so that at watering time you can use rainwater instead of drinking water.
Choose the storage that suits your garden. An ordinary water butt works if you mainly want to fill a watering can now and then. If you want a larger water reserve along a facade or garden edge, the Harves Rainwater Wall offers approx. 1,000 litres of storage per module, with a depth of approx. 30 cm.
A full module of approx. 1,000 litres equals roughly 100 watering cans of 10 litres. This is a calculation example, not an average garden usage figure or a guaranteed saving. By using stored rainwater, you free up room for the next shower.
As long as storage space is free, the rain wall temporarily holds back part of the roof water instead of draining it away immediately. That is storing water, not automatically infiltrating it into the soil. It does not guarantee protection against flooding; a suitable overflow and drainage are still required.
How much rainwater you can collect depends on the connected roof area, the rainfall and your connection. How long the supply lasts depends on your plants, the soil and the weather. A larger store gives more room for a reserve, but does not guarantee water during every dry spell.
When positioning it, consider a suitable foundation, anchoring, a tap-off point and an overflow. Have the connection and setup matched to your location. Use collected rainwater as garden water, not as drinking water.
