High pressure line cleaning is accomplished by using combination trucks. These large vehicles are designed to jet clean the interior of pipe systems and to vacuum the retrieved debris from an access manhole. Sewer lines must be cleaned prior to television inspections. The cleaning operator will use various nozzles to deliver up to 3,000 pounds of pressure per square inch of pressure to dislodge grease, roots and other debris. The vacuumed debris must be decanted and disposed of properly. After cleaning, clients will see improvements in system hydraulics and lift station performance, as well as a reduction in pump wear. Cleaning also provides increased system capacity, reduced customer complaints, and a reduction in overflows and bypasses. CES has the capacity to clean sanitary sewer lines, storm sewer lines, manholes, lift stations, and more.
