Cleaning is one of the most important aspects of our business for both maintenance purposes or in preparation for rehabilitation. Our services include pipe cleaning, vault and tank cleaning and hydro-blasting. We also provide vacuum services for debris removal to augment the cleaning operation.


Using a cleaning medium (water) that is readily available and environmentally safe, high pressure water jetting is a nondestructive cleaning method in which the equipment can be self transported. At 4K psi, the water exits the specially designed nozzles at 500 mph, thus creating a thrust to propel itself and the Kevlar hose through the pipe. From half inch lines to five foot wide culverts, we have to tools nessessary to remove material and open your lines. We have a full compliment of nozzles including chain flails to Stoneage Dolphins at 100 gpm to 24 inch grinders to remove rust from cast iron lines.

Sanitary Sewer

An extensive array of cleaning equipment, coupled with over thirty years of industry experience, enables MSI’s trained personnel to clean pipe from 1” diameter up through large diameter (60"). Root cutting and obstruction removal services are also available if necessary to ensure the pipe returns to normal operation.

Storm Sewer

Clogged storm drain systems pose the threat of flooding during heavy rains causing costly repairs to the structures they were designed to protect. We specialize in the removal of accumulated debris that, if left in place, could result in flooding and hazardous conditions. From hydro-cleaning to bucket machines, MSI has the experience and equipment necessary to return the drainage system to its best possible condition.


Horizontal edge drains range in size from one and a half to two inches in diameter. These wells utilize perforated pipe to dewater, relieving hydraulic forces in unstable locations. Over time the wells will become clogged with soil and roots and require cleaning. Hydro–jetting the pipe will cut root intrusions and remove mineral and soil build–up throughout the well.

Industrial Cleaning

Concrete Cutting:

Concrete cutting is performed using a hand gun capable of producing 10,000 psi water pressure with a 0 degree pencil jet nozzle. This procedure is effective in creating exposed aggregate from a cured concrete surface.

Wet Abrasive Blasting:

Requiring hand held equipment with pressures ranging from 4,000 to 10,000 psi, various abrasive materials are injected into the water flow through a Venturi nozzle. Very controllable results can be attained by this method. Water effectively retards the dust and reduces the heat (warping effect), which are major negative byproducts of conventional blasting methods. Abrasive materials range from sand to crushed walnut shells or almost any abrasive, free flowing material can be used depending upon the results required. A unique feature includes the ability to recover the abrasive and allow reuse.

Tube Bundles:

Flex lancing usually necessitates 10,000 psi water pressure. Tube bundle residue varies in thickness and density. Specialized rotating nozzle tips perform cleaning operations on these, sometimes totally restricted, tubes. Foot control valves are essential pieces of safety equipment for applications where the jetting operator is unable to see and communicate directly with the machine operator. This also applies to applications where a stainless steel semi flexible lance without a dump type trigger assembly is used.

Communication Conduits:

Today’s infrastructure was installed with yesterday's technology. Vitrified clay tiles with no mortar joints are susceptible to root intrusion and sifting backfill. Jetting flushes the conduits, cuts roots and lubricates the passage for insertion of a pull rope or interduct casing. Our unique jump jet capability allows us to jet along side a cable pair already occupying a conduit.
