Doing any kind of construction underwater requires the construction site to be dewatered beforehand. Your workers need a dry, stable environment to complete the repairs or new construction. Sometimes, though, a project may require water to also be diverted.
Types of Projects that Require Dewatering and Diversion
Many projects require water to be removed from the worksite for a safe, dry construction environment. Temporary cofferdams have conventionally been filled with earth and rock, though sometimes concrete or sheet pilings are used. However, today water-filled inflatable bladder dams have become the industry standard for dewatering construction worksites.
At times, the worksite may need to be dewatered and additional water may need to be diverted. This may include projects that involve bridge repair and construction, dredging, chemical spills control, fish habitat protection, environmental remediation, shoreline restoration, pipeline crossings, construction site dewatering, levee repair and construction, wetland management, construction of pumping stations, irrigation canals, and other manmade structures, and water storage.
All About Diversion
Sometimes diversion is necessary in construction to ensure an isolated, dry project area. In some cases, water is temporarily rerouted in order to prevent or minimize contamination of clean surface waters. It’s also instrumental in providing an effective temporary water barrier to allow for easier dredging of smaller waterways such as ponds and canals. Diversion provides an effective method of sediment control. Work zone sediment is prevented from entering the waterbody which is especially crucial when dewatering storm water. Finally, water diversion allows for maintenance of upstream fish passage if an area will be affected for an extended period of time.
The Dewatering Standard
Inflatable bladder dams have quickly become the leading method for dewatering in construction. They are easy to deploy, effective, and environmentally friendly. Consider investing in a water-inflated bladder dam for your future dewatering and diversion projects.
