MacEwans Flood Gate Enter Here


MacEwans flood gates are proudly manufactured and designed in New Zealand to stand up to the harshest environments.

The gates are normally mounted on the end of the pipeline but can be mounted in a variety of configerations

A small differential pressure on the back of the flood gate causes it to open and surf on top of the water discharging from the pipe.  When the flow stops the gate will close to prevent back flow.

MacEwans Flood gates are manufactured from cast iron and are fitted with stainless steel hinge pins and bronze bushes for many years of trouble free operation.


Flood gates are typically used for flood control, sewer outfalls, irrigation systems, pump discharge control, water and sewage plants.
