The Three Deciding Factors Which Determine What Level Of Dewatering Pumps You Need

Posted on: 23 April 2020

Flooding and the presence of groundwater can be a significant problem on construction sites in even the most arid parts of Australia. That is why dewatering pumps are an everpresent sight on most construction sites as they play an essential role in allowing foundation work to continue in any weather or physical location. However, that statement is only valid when you get the correct dewatering pumps for your project. Not all dewatering pumps are created equal, and the last thing you want to find out when using them for the first time is that they are not rated for your needs. Here are three factors which will make your choice of dewatering pumps far easier. 

Silt And Dirt Content

Almost all water found in construction sites is contaminated with some sort of silt, aggregate or sludge that will be drained out with the water. It is vital that you test the water before you use your dewatering pumps and only use a system that can handle the specific conditions of your groundwater. Smaller pumps will have far less robust filters than a wellpoint dewatering system and will be quickly overwhelmed if used on a bigger construction site. Not only will getting the wrong pump for your site slow down your construction progress, but it will also cost you thousands in repairs at a minimum, so make sure to take this seriously.

Size Of The Site

It should be evident that not all pumps can cater to every sized body of water, but often people overestimate the capacities of their chosen dewatering pumps. Whether due to stubbornness or simply ignorance, the result is always the same: a flooded foundation and a spluttering pump that will overheat and break down. Choosing a dewatering pump for your site requires exact mathematical calculations that take into account the quantity of water, the speed at which you want it drained and the distance the water has to go before it is dispensed. Always use a dewatering pumps expert if you can; otherwise, you are liable to make a mistake in these equations.

Environmental Conditions

Dewatering pumps should stay on-site with you until the foundations of the building are done and there is no more risk of flooding. During this time you need to know that your pumps will not just be able to clear any groundwater but also rainfall and dew which might occur naturally. If you are working in a particularly wet region, such as tropical Queensland or Tasmania, then you should look for dewatering pumps with a larger capacity for drainage. Remember: getting a more powerful dewatering pump system is better than getting one that is too weak.
