Dewatering services refer to the act of removing groundwater from a construction site. Building in South Florida usually means you will need dewatering, as groundwater is abundant beneath our feet. And while the Everglades once covered about 11,000 square miles of land, much of Florida’s natural wilderness has given way to cities and other forms of development, even if the groundwater has not. The dewatering process is generally done by pumping the water or through evaporation. Dewatering happens before excavation, which lowers the water table to reduce the chances of more problems during excavation and construction.

Why It Is Important

Construction sites are usually prone to water trenches which make excavation a nightmare. Also, construction sites that have high water tables are also prone to water trenches and will require dewatering services. Inadequate slopes also contribute to water trenches. The water must be removed to keep work on schedule and to provide a safe working area for construction workers.

You can use a water pump to dewater your site, but you need to pay close attention to the water discharge area. Without paying attention, you will cause soil erosion and other problems. A tip you can use is to use erosion management solutions to prevent erosion. For instance, you can talk to hydroseeding companies and have them plant hydro grass, which takes a short time to grow and is an effective erosion management solution.

If you plan to pump the water into lakes, wetlands, or directly into sewer lines, you need to make sure that you follow the best management practices and abide by local codes.

Precautions To Take

Once you have adequately planned for potential erosion, there are several other precautions you need to have in mind. For instance, you should never pump water directly into slopes. Besides eroding the soil, you are likely to cause damage to the property or road below. Use dewatering equipment such as wooded buffer during the process. Dewatering service providers will come with the equipment you need, so don’t worry about this.

During the process, you need to pay close attention to the land. If it shows any sign of instability such as visible cracks, change in moisture, erosion, and curved trees, you need to stop the process immediately. Enlist ground stabilization services before you continue to dewater your site.

Always make sure that the dewatering surface is either surrounded by grass or vegetation. As explained, this helps reduce soil erosion. Infiltration is at it’s lowest during rainy seasons so avoid dewatering during heavy rains. Water will move slowly as more pours in from the rain. The process will not function, so it’s best to avoid it altogether until the storms have passed.

Are you dewatering in an area that has oil, grease, and other chemicals? It is best to call dewatering services on site for this. They are familiar with the precautions that need to be taken into account when grease, chemicals, and oil are a factor. Oil and water separation will be necessary, for instance, and your construction site workers may not have the equipment or knowledge to handle the process.

Dewatering companies also understand water table conditions. It is, especially helpful to work with a company in your locality. They know all land conditions in your area and will be better placed to offer the services. If the water table is too close to the surface, your plans may fail, but a dewatering company will give you the best alternative.

The company will advise you on the best technique to use depending on the amount of water you need to be removed. Typically, sump pumps will feature during the process, but they may only handle a small amount of water.

Before you start, ensure you have the right permits and requirements sorted out from your local or federal agencies. This should be the first thing you take care of. A visit to the federal agency’s office will inform you of all the permits you need.

Sometimes, a complete engineering analysis is necessary before any work begins. Without removing the water, your site would be impossible to work, and you would be putting your worker’s health at risk. Excavation would be a nightmare, and you wouldn’t be able to get anything done.
