  • Patent number: 9328871
    Abstract: A system for containing and managing fluids produced at a work site, such as an oil or gas drilling site, includes one or more fluid containments formed as a basin for collecting and retaining fluids, a berm forming a perimeter of the containments, a layer of sand placed over each basin, a fluid-impermeable membrane placed over the layer of sand, and drainage stone placed over the membrane, filling the basin. A geotextile fabric can be placed over the membrane to help protect the membrane from adverse affects of the drainage stone. A leak detection system can be coupled with the membrane to identify potential leaks in a containment system. One or more catch basins can extend through the basin and the drainage stone filling the basin, to receive fluids. A drainage system is placed in fluid communication with the catch basins to drain fluids from a containment.
