What Are Sluice Gates?

sluice gates

A sluice gate is typically a metallic or plastic channel that runs through the top of the opening and has a closure flap. It has an inbuilt taper that is used to channel the flow of liquid waste liquid in a downstream direction. There are different types of gates available in the market such as solid sliding, semi-permeable, or perforated sluice gates. A sluice gate or mill is usually a closed loop structure where a thin metal sheet is used to channel the flow of liquid. Leet, flange, mill, or penstock gates are some of the common names in this industry.

Why need Sluice Gates?

Sluices, also called sieves, are devices that fit through the hole. They allow for the collection of sediment and other unwanted materials in water. In some systems, it also allows for the separation of sediments from the ground water. This is done by channeling the runoff from agricultural fields to the storm drain system.

Generally, a sluice gates’ primary function is to regulate the exit and entrance of solids and liquids from a pipe or other exit through a storm drain or another drain system. Their primary function is to close the exit pipe during an overflow while allowing the flow of storm water into the sewer system. If a storm drain or sewer line gets clogged, this type of gate is the only way to open it to the drainage of the storm water. It has been found that the flow of storm water into the sewer pipes is much lower than the flow of liquid waste water out of the pipes.
