“We can help with selecting, costing and buying your rainwater management system.Using our rainwater drainage design calculator, we (or you) can work out what size guttering and downpipes will be required on your project in your particular geographic location.”

The drainage design calculations

If you are confident doing your own rainwater flow calculations, you’ll find the calculator here: calculator.rainclear.co.uk

The outcome of the rainwater drainage design calculation depends on several things:

The size of the roof area to be cleared of rain and the pitch of the roof. The deeper the angle of the roof, the faster the water will be carried to the gutters and need to be swiftly cleared away down the drops.

The number of drops – i.e. how many suitable locations there are around the building for downpipes that lead from the roofline down to a subsurface drain. The fewer drops there are, the more capacity (i.e. a larger downpipe diameter) is required in order to effectively divert rainfall away from the building into drains and water butts.

The usual and the worst rainfall the location or geographic area of the building experiences (and is expected to experience in the future), based on historical records.

A lot of rain in a short period of time places greater demands on the system and needs more efficient management of the rainwater to effectively protect your property and foundations.
