Rain Barrel Works

Start with the roof, then the tank

Rain Barrel Works organises rainwater storage around the space outside your home: the collecting roof, the available base and the route between downpipe and vessel. Column, Terrace, Wallslim and Orchard provide different body sizes and nominal capacities, from 210 to 500 litres. Volume is one decision; access to the lid, overflow and low outlet is another.

The capture calculator makes a scenario from roof area, rainfall and your chosen collection factor. Add a reserve and planned daily draw to examine available water, or enter seven daily rainfall values to see a simple sequence of use and overflow. These are your assumptions, not a forecast for the garden.

Connection families matter as much as litres. Divert 25 matches the 25 mm inlets of Column and Terrace. Column 58 raises only its matching Column vessel. The larger tanks need their own connection and base planning, made explicit in each product description.
