What is a kerb outlet? They are essential parts of drainage systems which serve to remove the excess water from your property by directing it to the kerb on the street, which will then flow into the stormwater system.

Firstly, kerb has two spellings, also being written as curb. “Curb” is the American spelling of the word, where as “kerb” is the correct English standard as has been used since the mid 17th century. Since in New Zealand we use the English standard, we will go with the spelling “kerb”.

Kerb outlets can be used in conjunction with driveway channels, gutters and other types of water removal drainage systems.

We just completed a job for a customer which involved installing a kerb outlet for their stormwater drainage system.

For this job, we had to remove part of the footpath as well as some ground from their property in order to run the piping for the outlet. Once the ground was removed, we could lay down the pipe which was 100mm diameter uPVC in this case.

In this system the kerb outlet was used in conjunction with a 5,500L stormwater above ground detention tank. The outlet was connected to the gutter drain as a means of escape for the stormwater.

Once the pipes were laid, we reinstated the concrete on the foot path and to the neighbouring property that had to be removed. The road and driveway were then cleaned up from all the left overs of working there.

Why would you need to replace a kerb outlet?
Kerb outlets are crucial part of stormwater drainage systems that ensure that water being drained can be removed from the property onto the road, where it can then drain into the main drainage system. If your kerb outlet is blocked or damaged, you could find yourself with a flood in your yard, which could even cause damage to your home.
