Pumping stations can act as a holding chamber to collect stormwater, rainwater, sewage or wastewater. The pumps transfer the water or waste for reuse or disposal.
Available in a range of sizes to suit requirements, pumping stations can be installed in residential, commercial, industrial or mining settings. For larger commercial developments, there can be a requirement for one or more pumping stations to be installed.
An efficient pumping station is crucial. Improving the efficiency of pumping systems has numerous benefits, from being environmentally friendly to providing energy efficiency, to reducing costs.
Types of pumping stations
Different types of pumping systems are designed for different applications. You need to ensure you install the right one to ensure optimum performance.
Designed for stormwater, or effluent waste, a stormwater pump station consists of a collection tank for stormwater, with a submersible pump at the bottom. Rather than relying on gravity to cause the water flow, the stormwater pump provides additional pressure to transfer water to the discharge point.
Installation of stormwater pump stations prevents water from ponding in a basement, car park or paved area, which helps prevent flooding or overflow. It also allows the capture of stormwater for reuse.
When installing a stormwater pump station, there are generally specific regulatory requirements they need to meet.
Typical wastewater systems consist of a network of sewers and sewage pumping stations, which collect and transport wastewater and raw sewage from where it is generated to a wastewater treatment plant.
Wastewater systems can be designed to maximise the use of gravity to transport the sewage. These generally do not use energy or require the same amount of maintenance as other
pumping stations, which can result in a more efficient system.
Variations in the landscape can limit the viability of a gravity system, in which case, alternative systems may be considered.
Rainwater pump systems save water that would otherwise be wasted, allowing it to be reused.
Rainwater pumps can offer numerous benefits. They reduce water bills and alleviate pressure on reticulated water supply, reducing capacity restraints in stormwater systems, while also providing additional water supply during water restrictions or drought.
Generally inexpensive and easy to maintain, they can add value to commercial or residential properties.
An efficient pumping system
In order to design an efficient pumping station, you need to understand what is being pumped, where the pumping station will be located and where it will be discharged to. This will influence the necessary pump and station size.
Consider the size of the system, both of the chamber and the size of pumps required. Numerous factors can influence the design size and pumping station capacity required. These can include the invert level on the pump chamber, water holding capacity time and risk, and the pump flow rate to lower water levels.
Some may only require a single pump, while for bigger applications, such as commercial developments, a dual-pump system may be needed. For larger areas, or where heavier rainfall can be expected, a larger pumping system will be required.
In stormwater application, the required flow rate is determined by the catchment area and rainfall intensity, while for sewage pumping, the number of users will impact the necessary flow rate. Solids handling pumps are generally preferred for preventing blockages and ongoing maintenance issues.
Also, consider the type of pump station you choose. Different types are more suitable for certain applications, selecting the right one ensures your pump systems are providing maximum efficiency.
The pumping station could be concrete or fibreglass. It will depend on the planned application as to which is most suitable. Fibreglass is ideal for smaller applications, as it is lightweight and simple to install; concrete is good for larger applications, though consider if crane access is limited.
For some pump station applications, you may require council approval and or need to adhere to certain requirements depending on where the station is being installed.
Pumps need to be reliable and durable, and able to handle application requirements to work efficiently. The most efficient option will depend on the application and type of pump station. If the wrong size or type of pump is selected, it can result in cavitation, high energy costs, high maintenance costs, or even flooding.
