Surface and groundwater removal is important in establishing a workable excavation place. Looking for the best dewatering system for the environment provides quality results in the least amount of time. To make sure that you are choosing the best dewatering system, it’s important to keep in mind a few things. Here are some of the key things that you should consider to ensure that you are choosing the best dewatering system for your needs.
Understand the Available Options
There are a few options when it comes to dewatering systems. A wellpoint system is the commonest technique for excavations up to 25ft deep and contains a series of shallow wells that can be strategically placed around the site. Water is then pumped to the surface through connected pipes. You need to know that deep well systems contain drilled wells and leverage electric submersible pumps to take the water out of the work area. We have sock dewatering systems that utilize perforated pipes that are installed with a trenching machine that lays the socks, approximately at a depth of 20ft. Lastly, we have open pumping systems that contain sump dewatering, which is efficient for large amounts of water or shallow excavations.
Assess Excavation Depth
It’s important to note that the best dewatering system highly depends on the depth of excavation. Usually, a perfect dewatering system highly depends on excavation depth. For instance, well-point systems are perfect for dewatering in shallow foundations, trenches, and utility works. On the other hand, deep well systems can perfectly work at depths below 26ft and remove large amounts of water, although it may take a long time. Sock and open pumping systems also work perfectly for shallow excavations but work more than wellpoint, usually between 5 to 15ft. Both options are essential for drawing water quicker, but open pumping systems can be designed for minimum costs. What’s more, they can remove large volumes of water and redirect discharge.
You will want to understand the soil type before choosing a dewatering system. Soil is a crucial consideration in choosing a dewatering design. The geography and group contents can give you an idea about the dewatering application you should utilize, but permeable layers can help you decide the best application to choose. You need to know that the runtime of the dewatering system can be affected by soil type and materials, and this might influence the timeline of your project. If the soil is coarse, your preferred dewatering system will run faster. On the other hand, if the soil is fine, then your dewatering system will take more time to dewater. Before choosing any dewatering system for your project, make sure that you have checked soil types and geography to help you make an informed decision.
Filtration and Monitoring
There might be some additional environmental rules depending on your project and job site. So, to will want to make sure that you have added a filtration system for treating pumped-out water before it’s discharged. This way, you are assured of remaining compliant. Make sure that you have contacted a professional filtration engineer to assist you in analyzing and designing a perfect solution that guarantees compliance.
