There are several specific processes that often play a chief role in stormwater management for any construction site, and dewatering services are typically among these. What is construction dewatering, and which different techniques might dewatering contractors use to prevent chemical runoff and other issues?
At Cearley SWPPP, we're here to offer the best SWPPP services in all of Utah, including serving as the top dewatering company in the state. What exactly is construction dewatering, and which techniques might our dewatering contractors apply to your site to keep it in compliance? Here are some basics on this important area.
For those unfamiliar with the term, construction dewatering is simply the process of removing groundwater or any other type of water from a construction site. This service is often necessary to ensure that construction can take place safely and effectively, and it's a key part of ensuring compliance with environmental regulations and keeping workers safe.
There are several purposes served by construction dewatering services:
There are several different techniques that may be utilized during construction dewatering. The most appropriate technique will depend on factors such as the type of soil at the site, the amount of groundwater present, and any regulations or restrictions that must be followed. Some common techniques will be discussed in our subsequent sections.
One of the most common and efficient techniques for construction dewatering is sump pumping. This method involves placing pumps in excavations or trenches and using them to remove excess water from the site. The pumped water can be discharged into nearby storm drains, retention basins, or other approved locations.
Sump pumping allows for quick and efficient removal of water from the site, making it an ideal choice for most construction projects.
Wellpoint dewatering is another effective method of removing groundwater from a construction site. This technique involves installing a series of shallow wells around the perimeter of the site and using vacuum pumps to lower the groundwater level. The pumped water can then be discharged into nearby approved locations.
Wellpoint dewatering is particularly useful in areas with fine-grained soils or high water tables, as it can be used to lower the groundwater level below the excavations. There are also settings where "deep wellpoint" dewatering is used, which involves the groundwater level being lowered below the excavation level using boreholes and submersible pumps. This method is often used for deeper excavations or in difficult soil conditions.
Also known as trenching, channeling is a technique that involves digging trenches in the ground and then lining them with filter fabric. These will then be accompanied by a pump, which is used to remove water that builds up in the trench and discharge it to an approved location. This method is typically used for smaller projects or when the groundwater level is not too high.
Similar to the wellpoint method in some ways, the eductor method differs in that it pulls water using an existing high-pressure water suction system rather than a vacuum. This is another method that can be used in areas with fine-grained soils, high water tables, or other challenging conditions.
No matter which dewatering method is chosen for a construction site, it's crucial to work with experienced and knowledgeable contractors who understand the complexities of stormwater management. In addition to ensuring compliance and safety, working with quality dewatering contractors can also save time and money by preventing delays, accidents, and potential fines or penalties. With proper dewatering services in place, construction projects can proceed smoothly and efficiently, leading to successful project completion.
