Silt Trap

An inspection chamber within a drainage system. The chamber allows soil sediment, that is suspended or contained within drainage water for a period of time, to settle in the base of the chamber. Less contaminated water will eventually be discharged in the outflow pipes once the height of those pipes has been reached. It is important to periodically inspect and clean out silt traps, otherwise sediment will build-up and clog up the drainage system, making it ineffective. It is also called an inspection chamber.
