The top swale

The top swale

Finally, after discovering and experimenting with swales for some time, I have rerouted the rainwater from the house roof to a newly created TOP SWALE. The new excavations run in a fairly straight line through the orchard and overflow into the recently reconfigured garden swales.January 18, 2013  rain  water  swale 
The way of the swale

The way of the swale

A swale is a permaculture technique designed to improve water catchment and retention on slopes. Applicable to varying scales, a swale is basically a ditch or terrace created along a contour line with the removed soil piled on the downhill side. As rainwater drains down the slope above is is caught and absorbed by the swale. Plantings made along the swale will have access to additional moisture for extended period.

My first attempt at a small swale follows the contour line on a northwest facing slope below an existing track. Because of the small size I was able to dig this by hand over 2 periods, using an A-frame level. Over the course of the next few months we will be scattering the kitchen scraps along the length for the chooks to work over, adding their manure and nutrients from the kitchen. Finally it will be planted up in a variety of different plants from ground covers, bulbs and shrubs to fruit and firewood trees.
