Road gullies are water management chambers, designed to collect surface water in the street, and carry that water to the underground drainage pipe system, where it is then taken to a watercourse, storm drain or soakaway. 

Up until 1990 or so, road gullies and yard gullies tended to be big items of clay ware, but their inherent fragility was always a problem. They were slowly replaced with heavy-duty precast concrete elements, which are considerably stronger but also much heavier – requiring serious site equipment to get them located. The larger 450mm diameter units weigh a lot more than just one operative can be reasonably expected to handle, and so they will have to be craned into place by an excavator.

These days, durable road gullies are usually manufactured from plastic, this makes them much lighter, much more cost-effective, and far easier to install as it is merely a matter of surrounding the plastic road gully in concrete. The 300 x 600 gully has an outlet of 110mm to go to 4 inch drainage pipe (110mm), whereas the larger gullys have an outlet to go to the 160mm drainage pipe.
