This article will help you understand what stormwater drainage is, the different types and why maintence is vital.
What is storm water?
Stormwater is the water that drains off a house site from the rain that falls on the building roof and land, and everything that the water carries with it. This can include soil, organic matter, litter, fertilizers from gardens and oil residues from driveways, which can pollute downstream waterways. Rainwater refers only to the rain that falls on the roof, which is usually cleaner.
What Is Stormwater Drainage?
Stormwater drainage is the system that is installed to manage stormwater. It includes gutters and downpipes, which collect rainwater from the roof, and a series of pipes, drains and channels that carry the water away from the house. The system may also include a stormwater tank, which can be used to store rainwater for garden use or to release it slowly into the environment so that it does not cause downstream flooding.
What Different Types Of Stormwater Systems Are There?
There are two main types of stormwater systems: surface water systems and subsurface water systems. Surface water systems discharge stormwater onto the ground surface, where it flows by gravity through gutters, downpipes and open drains to a natural outlet such as a creek or lake. Subsurface water systems discharge stormwater into the ground, where it is absorbed and filtered by the soil.
The type of stormwater system you have will depend on the size and layout of your property, as well as the rainfall conditions in your area. Your local council or a qualified engineer can advise you on the best system for your home.
