AgriTank planning tool

Plan rainwater storage
with confidence.

Estimate how much rainwater your roof can collect, account for practical losses and see how a proposed tank capacity fits the site.

Roof area×Rainfall×Collection efficiency=Harvestable water

Indicative mean annual rainfall: 620 mm.

Planning estimate only. County figures are indicative mean annual rainfall values; rainfall is uneven through the year and real collection depends on local weather, roof material, system design, demand and overflow. Confirm the selected product specification and installation requirements before ordering.
