SR-SERIES precision jet cutting equipment from ID-TEC can be used with water pressures up to 29,000 psi for trenchless removal of FOG, stoppages, calcium, roots, plastics, cement and concrete in 7- to 40-inch pipelines. Water is pumped under high pressure through a steerable cutting nozzle at the front of the robot. The remaining water blast is aimed at the blockage and cuts holes in it. The pressure inside these holes rises until it breaks the concrete loose. A color camera and high-power LEDs provide perfect vision during the operations. 503/504-8474; www.sewerrehabilitationseries.com.
