Adelaide Flood Control System: How Does It Work?

Each year, the floods in Adelaide makes its way to the populated areas, costing millions of dollars and destroying neighbourhoods, causing damages, and thwarting the local economies. When the main city is overfilled, it will be exposed to water damage. 

This is why it is essential to know about flood control systems.

 Severe rainfall and unusual tides in the Brown Hill Creek area can cause floods in Adelaide. In this article, we will tell you all about flood control management and how the flood control system works.

What Is Flood Control And Its Significance?

Flood control refers to the techniques utilised to prevent or reduce the damages caused by flood waters. Some common flood control methods are installing rock beams, sandbags, rock rip-raps, slope upkeep with vegetation, or applying soil cement to steeper slopes.

Adelaide flood control is essential to keep flood damage to a minimum. They also help control any development into unsafe floodplains while protecting the properties and lives of those in them. 

Financially, flood control will take the burden off the communities and municipalities where flood damage is frequent and extensive. It also ensures that fresh, uncontaminated water is available for drinking.

How Does Adelaide Flood Control Work?

The flood control system in Adelaide is made for the protection of houses when the primary lines of the sewer are overfilled. Flood control systems comprise part of 1-2 brass one-way flow valve, which helps prevent sewage from flowing back to the house. It allows the sewage to flow to the sewer line of the city. 

The flood control system also consists of an ejector pump. These pumps discharge wastewater from the house when the sewer lines of a city are closed.

Types of Flood Control Systems to Control Floods in Adelaide

The following are the most commonly used systems to control Flood in Adelaide:

Stand Pipe

The standpipe is an inexpensive method that works with floor drains. The simple installation system keeps the pressure back on the drainpipe. It is located above the floor level. 

With this, the standing water will be pushed back. 

Lift Stations

The lift station is among the best methods for protecting the home from sewage backups or floods. 

The lift station puts the basin with a series of pumps between the house and the city’s sewer. Rather than using gravity to push down the water, lift stations use commercial pumps to move the water to different elevations in the sewer system. 

This flood control method protects the properties when the neighbourhood backs up.

Overhead Sewers

Overhead sewers are another efficient method that you can opt for to get protection against floods in Adelaide. The sewers with the battery will completely floodproof your house. 

Fixtures at lower levels are not tied to the sewer. Rather, they drain it to the ejector pump to push the water back into the in-flight sewers. 

It is the best option for frequent flooding issues, especially if the sewer is near flood belts, such as Brown Hill Creek.


Flood control and management systems are crucial since they can help the residents of flood-prone areas avoid any significant losses. The Brown Hill Keswick Creek Stormwater Project is a comprehensive Stormwater Management project that aims to minimise severe flood risks and safeguard houses and other properties in and across the Brown Hill Creek catchment area. 

Before the project delivery, almost 4,000 properties would remain vulnerable to flood-related damage. However, after the project delivery, the figure will drop to 63.Visit Brown Hill Keswick Creek Stormwater Project’s official website to learn more about this collaborative undertaking by five councils.
