are typically found in parking garages, auto repair shops and large commercial spaces with floor drains. What most people don’t know is sand trap’s should be serviced (pumped) on an annual basis to prolong the life of the tank and protect the city sanitary sewer from harmful chemicals and oils.
What is a sand trap? A sand trap is a tank that separates waste water collected from area floor drains. When liquid enters the tank, heavy debris falls to the bottom. Since oil is lighter than water it floats to the top. The remaining liquid flows through the tank and relatively clean water enters the city’s sanitary sewer system.
Servicing your trap on an annual basis is important to prolong the life of the tank. Over time, sediment will build up on the bottom of the tank. this can lead to major blockages and flooding throughout the garage. It is important to remove sand deposits before this occurs. Pumping the tank also prevents large amounts of oils and chemicals from overwhelming the system and distributing it into the sanitary sewer system.
