Once you have done your research and purchased the right sewage pumping station Australia, it is important to know how to correctly install your pump station. This may seem like a complicated task but if you hire a professional to do the installation, it will be a straightforward, simple procedure.
Choose a suitable location
Your pump station will need to be installed below the ground level. It is, therefore, important to think about the exact location you want to install your pump station. It is crucial to allow for falls in the drainage and before you start digging, you should check for any underground cables, service ducts and pipes. If the tank needs to be installed under a footpath or road, additional provisions such as a manhole cover will be required and these should be bought before you start the installation.
Excavating the opening
At this point, you will need to dig a hole for your pump station. The hole should be about 500mm deeper than the length of the tank. If it is dug by hand then the size should be shored up to prevent slippage of the earth. If you are digging using a machine then you should ensure they are battened for stability. You may need a dewatering pump to drain away all the available groundwater.
Prepare the excavation
Place a layer of hardcore into the base of the excavation. Ensure this is 200mm thick. However, if the conditions of the ground are good, 50mm will be enough for your sewage pumping station. You should then cover the hardcore with concrete and compact and consolidate them well. The minimum grade of your concrete should be between 25mm and 150mm thick.
Install your tank
Now you are ready to install your tank. You should slowly lower the tank onto the damp base and allow the fleet to settle into the concrete. It is crucial to ensure that connections and pipes are positioned correctly.
Secure the tank
If you are happy with the position of the tank, you should fill it with water and secure it in place using concrete (grade 25). The concrete should be poured evenly around the tank to a height of about 600mm and a thickness of about 100mm. Vibrate the concrete to avoid voids. You should then connect all the pipework on the packaged station and backfill using grade 25 concrete. When backfilling, take care to keep the tank level.
Make the final connections
Wiring is the final stage. You should give the concrete enough time to set. Once the concrete has set, remove water from the tank. You are free to install the pumps and your float switches. Make the final electrical connections.
When installing a sewage pumping station Australia, you should seek professional help to help with the commissioning and wiring service. A professional will test the connections and ensure that your new sewage pump station is up and running properly. He can also issue a commissioning and wiring certificate for your records.
