Rainwater for your garden, on tap
The Platin Garden Comfort system collects the rain that falls on your roof and stores it underground, ready for watering the garden and outdoor cleaning. It’s a complete package for homeowners, self-builders and installers: tank, filter, pump and hose connection boxes, chosen to work together.
How it works

Rain runs from your downpipes into one pipe and into the tank. On the way in, it passes through a filter that keeps leaves and debris out. A pressure-sensitive submersible pump sits in the tank. When you open a tap or hose valve, the pump starts and supplies water under pressure; when you close it, the system re-pressurises and the pump switches off. The pump restarts automatically and has dry-run protection. The pump draws water through a floating intake.
Choose your size
The Platin is a shallow-dig tank: it’s wide and low rather than tall, so it needs a shallower hole than a traditional upright tank. It’s made from 100% recycled plastic and is installed with gravel backfill rather than concrete, which makes installation simpler and saves around £60 per cubic metre. Platin tanks are trusted across Europe for their reliability in rainwater harvesting.
| Capacity | Length | Width | Height to tank shoulder | Weight |
|---|---|---|---|---|
| 1,500 litres | 2,100mm | 1,250mm | 700mm | 80kg |
| 3,000 litres | 2,450mm | 2,100mm | 735mm | 170kg |
| 5,000 litres | 2,890mm | 2,300mm | 950mm | 240kg |
| 7,500 litres | 3,600mm | 2,250mm | 1,250mm | 360kg |
All sizes have an 800mm tank dome with a 315mm dome collar. Choose a pedestrian lid for lawns and garden areas, or a vehicle lid if the tank will go under a driveway.
