The Precision Jet Cutting System from ID-TEC combines waterjet cutting and jetting to eliminate roots and other blockages from sewer mains and lateral connections. A sewer rehabilitation robot is equipped with a camera, a cutting nozzle and an adjustable high-pressure pump. FOG, sludge, calcium, small roots and other deposits are jetted away with pressures up to 4,500 psi. Water pressures between 3,000 and 15,000 psi eliminate root intrusions by jetting away the dirt and small root branches first. Then the water blast cuts off the main root. It can be used at ultra high pressures to remove or cut hard plastics, clay, cement and concrete fast and precise without damaging pipe walls. The water blasts holes in the cement or concrete, causing the material to break loose from pipe walls as pressure rises. It can be used for cleaning and scuffing pipe surfaces for better bonding of CIPP relining materials. The robot suffers less vibration using the system, and water blasts are less likely to cause explosions. 503/504-8474; www.sewerrehabilitationseries.com.
