Factors that influence the cost stormwater pits and drains installation

Before starting the job, your plumber will have to inspect the area where the stormwater pit and drain are to be installed. After doing the inspection, the plumber can determine how much to charge you by taking a variety of factors into consideration.


Stormwater pit and drainage systems come in a variety of shapes and sizes. The pits can be made from plastic or concrete, and the drains can be made from plastic or aluminium. Concrete pits are more expensive, but they are a worthy investment because they are built to last. Plastic pits can either be light-duty or heavy-duty, but they are typically more affordable than their concrete counterparts.


A bigger stormwater pit and drainage system will usually be more expensive to install than a lighter one. This is because they are heavier, and they take more time to be properly installed. However, when it comes to stormwater pits and drains, the smallest option may not necessarily be the right one. Make sure to seek advice from your plumber regarding the best size for your property.

Additional services

In some installation jobs, excavation might be needed for the stormwater pit and drainage system to fit properly. This will likely drive up costs. Another thing that can add to your expenses is having custom-made storm water systems. Custom-made systems are more expensive because they are tailored to your exact specifications.

Rates vary from state to state

The rate is a bit higher in Queensland where plumbers charge around $77/hr for the same type of service.
