Hydro excavation is a safe, non-destructive digging technology used to avoid potential damage caused by mechanical excavation. The underground infrastructure is crowded with pipes, ducts, sewers, water lines and electrical conduits. This process uses pressurized water and a powerful vacuum to remove the loose material or liquid, exposing the site without interfering with the existing utilities.
MSI’s combination trucks are equipped with a high power suction unit to remove, store and transport wet material including liquids, sludge and slurry. The material is vacuumed through 6’ tubes into a ten-yard debris tank located at the rear of the truck. Adding extensions to the tubes allows the vacuum to reach the base of a manhole or tank to remove debris. This method is also useful in removing material from ponds, settling tanks, lift stations or any application where the removal of liquid waste is necessary. Once the material is on board, it can be transported to the disposal site.
For projects requiring dry debris removal, MSI offers vacuum services for the collection and removal of materials such as gravel, brick, rock and dirt. The powerful suction unit draws the material into an on-board tank for ease of transport and disposal. The dry vacuum units are particularly effective when exposing underground utilities prior to boring as the work site remains dry and ready for further work. A rotating, extendable boom allows further versatility when accessing difficult to reach locations.
To assist in the disposal of waste material collected from cleaning and pumping projects, MSI utilizes 20 and 30 yard water tight containment units to separate liquids from solid material. The containment units are fitted with an internal stainless steel filtration system. Various filter fabrics and meshes are installed for finer screening per the project specifications. The phase separator accepts material directly from pumping or from offloaded trucks via specially designed elevator ramps. When the dewatering process is complete, the solids are ready for transportation to a designated disposal site.
MSI employs a variety of tools and methods in response to spill containment tailored to the conditions at the site. Flow-through plugs are used to contain the spill once the boundaries of containment have been established. By-pass pumps, vacuum trucks, phase separators and dewatering systems are all essential to successful spill containment.
