Although we need water to sustain life, oftentimes it can be a nuisance, and sometimes even downright dangerous. Water destroys building materials and presents other hazards. Silver Leaf SWPPP provides dewatering services to building contractors, construction companies, site managers and anyone involved with SWPPP construction projects. We provide both commercial and residential stormwater management solutions.
Many construction stormwater general permits call for dewatering before the project begins. The purpose of dewatering is to lower the water table, usually by pumping the water out before digging begins.
Water interferes with builders’ ability to construct a building or other structure, such as a road or bridge. Water destabilizes the hole, allowing the sides to fall in and creating a dangerous situation in which areas of land could suddenly collapse. This prevents walls from being erected, cement from hardening and stability from being achieved. Working in a hole that has not been properly dewatered threatens not only the intended structure, but the workers in the immediate area as well.
While pumping water out of a hole may not sound that complicated, where the water goes next is critically important, and it depends on the landscape and other factors.
Sometimes the water can be pumped directly into a storm drain or watershed area, but not always, and making a mistake in this area can result in fines and/or a cleanup order. Certainly if the water contains any contaminants, it must be treated before being released.
If the water is not going directly into a storm drain, it must be released in another safe area, such as a forestor an area of thick vegetation. The thicker the vegetation, the less chance for erosion. When choosing an area, it’s important to avoid slopes, even if they are covered with grass and trees. A lot of water on a slope could quickly destabilize it and cause trees to fall.
Dewatering is often an ongoing process for a SWPPP construction site. To ensure no harm is being done, it’s important to test the water before dewatering and at regular intervals afterward to ensure your project is not impacting the water supply.
At Silver Leaf SWPPP, we take care of the permitting, testing, construction and monitoring of your dewatering system. We file reports on your behalf and create records of each stage of the process — including ongoing testing — and keep them on file for you electronically for you convenience. If state regulators need proof of your SWPPP efforts, it will be at your fingertips.
