Bypass Pumping

By-pass pumps capable of handling 2,200 gpm flows are used when the need arises to isolate areas for rehabilitation. The pumps are specifically designed to handle sewer discharge and slurry in caustic environments.

Pond Pumping

Holding ponds require periodic removal of accumulated sludge to restore the pond to its maximum holding capacity. Care is taken during the pumping and debris removal process to prevent damage to the liner or earthen subsurface.

MSI employs heavy-duty hydraulic submersible pumps capable of moving water, sewage, sludge, industrial waste, winery byproduct and slurries at a flow rate of 1,400-2,200 gpm with a maximum solid intake of 3”. Submersible pumps can be staged as stand alone, wheeled or afloat as the situation dictates.

Pond effluent can be pumped to an adjacent holding area or directly into awaiting trucks for transport and disposal. Dewatering systems can be integrated to aid in the disposal process.


To assist in the disposal of waste material 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, rigid, stainless steel filtration screen. Varying filter fabrics and meshes can be installed for finer screening if necessary. The phase separator accepts material directly from pumping or from offloaded trucks via specially designed elevator ramps. The solids can then transported to a designated disposal site.


Digesters contain solids and byproductsand they prove to be the hardest to clean. The cleaning procedure requires large amounts of additional water to break down the encrusted solidified mat. In addition to water, large volumes of air are sometimes injected to help percolate the material. These labor intensive "Jackpots" test both man and machine.
