An electrical substation is an integral part of an electrical generation, transmission, and distribution system. Environmental rules and regulations for electric power substations can be strict, requiring oil containment areas discharging into a sanitary sewer. In many cases national or local fire codes also require that these containment systems be designed to minimize the spread of fire within the substation or outside the operating areas so that any discharged oil will not create a hazardous situation to the public, neighboring buildings or equipment. As a result, proper secondary containment system design is essential to control oil contaminated drainage or leaks around electrical equipment and associated storage tanks, pipes, valves and fittings.
