A green garden starts with water you saved yourself
Your garden gets a good downpour. A few dry days later, your plants need water again. Keep some of that rain for later, in a wall that belongs in the garden you love spending time in.
Rain today, a green garden later
You want a green garden and a pleasant outdoor space, without a big tank taking over. Keep part of the roof water in a slim wall and use it when your plants need it.
1. Collect
Roof rain runs through the filter into the slim wall instead of flowing straight away.
2. Store
Around 1,000 litres per module, in a wall about 30 cm deep. Keep rain along a suitable façade or garden boundary.
3. Water later
Water your plants, hedge and beds from your own reserve on dry days. A full module holds about 100 ten-litre watering cans.
Rainwater is naturally soft and low in lime. A great choice for your plants — and a smart way for you to use less tap water.
One reserve, so many solutions
- A green garden, less tap water. Give your flowers, beds and hedge soft rainwater from your own reserve. Put the rain to work for the greenery you love to watch grow.
- Useful beyond the garden. Use rainwater to rinse your car, clean your garden furniture or wash your tools. These outdoor jobs do not need drinking water.
- Give rain a new purpose. HARVES collects roof water that would otherwise flow straight away. Use your reserve in the garden and make room for the next shower: a practical contribution to more thoughtful water use.
