Rainwater Harvester

• Underground rainwater harvesting systems from GRAF are make ecological and economic sense.

• Up to 50 % of drinking water can be saved, preserving groundwater reserves and taking the strain off wastewater treatment systems.

• The flat Platin tank with a volume of 1,500 l or more is easy to install yourself.

• Rainwater can be stored from anywhere between one week and indefinitely.

• The more consideration you put into your storage system – using the right materials, preventing algae and mosquitos – the longer your rainwater's shelf-life.
