Abstract:

A unique subsurface system was designed and implemented for draining such a natural depression in the City of West Lake Hills, Texas. This subsurface drainage system uses a part of the natural depression as a detention basin for storms of design frequency of 25 years or less. A filter system was installed in the natural depression to remove undesireable elements of the surface drainage. Filtered surface runoff is then collected by a system of perforated pipes and delivered to a drain well located at the lowest point of the natural depression. This system of managing storm runoff has proved to be very cost-effective, trouble-free, and efficient for the City of West Lake Hills, which experiences several high intensity rainfalls annually.
