If you have a mud run in your yard a bioswale might be a perfect option. Swales are ditches lined with rip-rap (rough stones), compost or vegetation to help direct and filter water. In general a bioswale is made by creating a wide gently sloped ditch and filling it with a natural filtration device such as those previously mentioned. Swales are a great way to naturally and sustainably prevent erosion and run-off. Swales work by filtering out pollutants and distributing the flow of water. The construction of a swale can be quite specific from the grade of the slope to the amount and type of materials used, or it can be more informal. To find out more about swales, give us a call to arrange an appointment 301-603-1080.
