How do I collect rainwater ?
To collect rainwater, you will need a water butt connected to a downpipe via rainwater diverter.
What are your water butts made of?
All Ecosure water butts are manufactured from high quality Medium Density Polythylene (MDPE). This strong durable material is weather and impact resistant.
How do I install rainwater diverter?
You can install a diverter anywhere on our water butts. We would recommend near the top but not too near the corners
Can they be installed underground?
We manufacture a range of water tanks specifically design to be installed underground. Available in non-potable and potable versions.
How do I get the rainwater out?
Each water butt has brass outlet moulded into them during the manufacturing process. This outlet can be used to attached a tap or shut off valve.
