Simple rain gardens

Posted on

Michael Mobbs has blogged about a very simple approach to rain gardens, where water off rooftops is used to sustain pavement gardens. To quote:

Notice how the water from the downpipe is being diverted by a Barloch water diverter located about 1 m high above the pavement so that rainwater, which would otherwise flow to the gutter and be wasted, may be directed by gravity below the footpath to water the garden beds some metres away.

This is exactly the sort of simple, low-tech approach that we should be using more of…

    Maybe I can use this to justify not installing a water tank, now we’ve had to disconnect them from the clogged stormwater “drain” 🙂

    Don Burke recommends something similar in a book about practical gardening (or some such thing). He diverts his tank overflow onto a slightly concave lawn that gently heads gently down to cover as much of the garden as possible, giving the garden a good chance to absorb the water.
