Swales and berms to capture runoff

Swales and berms are effective permaculture techniques for water conservation that can be implemented in your garden or landscape. These techniques help to capture and retain rainwater, preventing runoff and allowing it to infiltrate into the soil.

A swale is a shallow ditch or channel that is strategically designed to catch and redirect water. It is typically dug along the contour of the land to slow down the flow of water and encourage infiltration. The excavated soil from the swale is then used to create a berm, which is a raised mound of soil placed on the downhill side of the swale. The berm helps to further capture and hold water, allowing it to slowly seep into the surrounding soil.

By using swales and berms, you can effectively prevent water from running off your property and instead utilize it to nourish your plants and recharge the groundwater. These techniques are particularly useful in areas with heavy rainfall or sloping terrain.

The benefits of swales and berms include:

• Increased water infiltration and retention
• Prevention of erosion and soil loss
• Recharge of groundwater
• Creation of microclimates for plants
• Reduction of irrigation needs
• Improvement of soil fertility

When designing and constructing swales and berms, it is important to consider the natural contours of the land and the specific needs of your plants. Proper maintenance, such as regular inspection and removal of debris, is also necessary to ensure their effectiveness.

Overall, incorporating swales and berms into your permaculture design can significantly enhance water conservation efforts and contribute to a more sustainable and resilient landscape.

Greywater recycling for non-potable use

Greywater recycling is an effective technique for conserving water in a sustainable way.
