Stormwater pumps are wonderful innovation because of the important purpose of collecting, pumping and treating stormwater. If stormwater accumulates, the chance of flooding is likely. That’s why these submersible pumps siphon large volume of stormwater collected on car parks, driveways, residential, commercial, industrial area and other places where stormwater has the tendency to be stagnant. Installation of stormwater pumps are included in drainage infrastructures particularly in those area where heavy rain is an expected occurrence.
Since floodwater contains debris like trash, weeds, leaves, soil, sand and mud, stormwater pumps must ensure that these water before going to stormwater system is free of these coarse debris.
With a critical function such as this, what is the best material for stormwater pumps?
Polyethylene Stormwater Pump
If you would be using the stormwater pump for residential or industrial applications, stormwater pumps made out of polyethylene would suffice because of its durability and flexibility to be molded into the shape of the tank and the maximum volume of estimated stormwater that it would be pumping. Polyethylene is also light and easy to install thus preferred by homeowners since installing it is something that could be done in a day especially by those who already have an idea on how to install these pumps. Size range is between 100 liters to 10,000 liters of stormwater.
Fibreglass Stormwater Pump
For those dealing with stormwater that might have been mixed with chemicals, consider fibreglass pumps for stormwater applications. These pumps are resilient and preferred for industrial wastewater applications. Similar to polyethylene, they could also be customized depending on the requirements. Another similarity with polyethylene is the size range. Used by small to midsize pump stations, fibreglass stormwater pumps are recommended especially if the tank used is unusual in shape.
Concrete Stormwater Pump
For bigger stormwater applications, opt for concrete because it could handle between 10,000 up to 30,000 liters of stormwater. Although, it is difficult to install and would require the help of a crane. But it is not as prone to leakage compared with polyethylene or fibreglass as long as a strong water sealant is placed. Pipe connections is also not as easy compared to the other two material. If choosing concrete, make sure to purchase one that could handle more than 10,000 liters of stormwater so it would be cheaper.
When choosing, the stormwater pump, you have to consider four things. First, the volume of stormwater. When you have an idea the maximum volume of stormwater that the pump would be dealing with, it would be easier for you to determine the type of pump that would meet this requirement. Second, the condition of the area where the pump would be installed. Third, your budget and fourth the main purpose of the pump.
With these four considerations, you would be able to easily narrow down which stormwater pump is best for you. Seek professional advice especially if you would be dealing with water mixed with chemicals or if you would be dealing with a larger volume of stormwater to ensure that installation would go as smoothly as possible.
