Removing a few thick tree roots that grew into a 200mm (8″) VCP sewer pipe from the joint. 500bar (7,250psi) was used in combination with a rotary nozzle on the water jet cutting robot to remove the root infiltration in minutes.

Removing a few thick tree roots that grew into a 200mm (8″) VCP sewer pipe from the joint. 500bar (7,250psi) was used in combination with a rotary nozzle on the water jet cutting robot to remove the root infiltration in minutes.

Fat and grease from various upstream located restaurants had settled inside this 12” (300mm) concrete sewer main line until the pipe flow was eventually blocked.

Precision water jet cutting with 7,250psi (500bar) water pressure was used with a rotary nozzle to remove the solidified fat and grease deposits fast and accurate.

Concrete slurry with aggregate was poured into 250mm, 375mm and 450mm (10”, 15”, 18”) sewer mainlines after boring into an unmarked sewer line during ground stabilization work in a coastal condo development near Los Angeles. The concrete blocked the sewage flow from nearby Marina del Rey towards the treatment plant.

Concrete that was meant for the foundation of a building had filled a stormwater pipeline near Amsterdam, the Netherlands, after one of the reinforced concrete foundation pillars was drilled through the line.

Removing the grease film and taking care of tree roots infiltrated from joints, cracks and lateral connections to prepare a pipe for the installation of a cured in place pipe (CIPP) liner.

Have a look over the shoulder of this operator while he removes grout from this Sewer Pipe with the R125 transporter and WJ125 water jet cutting equipment at 1000bar (15,500psi).

The concrete found its way into a 20” (500mm) drainage pipeline near the runways of a large Airport to settle and form an impossible blockage.

A walk in the park for our water jet cutting equipment. The blockage was removed in a few days.

A grout mix meant for soil stabilization found its way into a vitrified clay sewer main pipeline during supportive construction for subway tunneling. The slurry settled inside the pipe causing a serious blockage.

Root infiltrations from pipe joints and lateral connections are no problem for 500 bar (7,250psi) precision water jet cutting. Multiple massive root infiltrations are blasted into wood pulp and removed within minutes.

Limescale, the cristalized mineral deposits often found in sewer pipelines of hard water areas, has been succesfully removed from multiple sewer pipelines in the Swiss Alps by H.Jakober with the Sewer Robotics water jet system.

The calcium carbonate had build up over many years and was so hard that it required up to 2500bar (36,250psi) to remove at some sites.

The Sewer Robotics’ robot R160 with the attached water-jet nozzle tool WJ180 was inserted into the pipe. A pump unit with up to 14,000 bar @ 18 LPM (20,000psi @ 10gpm) provided variable water-jet pressures throughout the cleaning process. After 3 days approx. 45M (150ft) of 30″ pipe were clean and the debris removed. All this without any interruption of the plant operation.

Calcium mineral deposits had built up over years in this 250mm (10″) PVC pipeline and were removed with the Sewer Robotics water jet system.

The calcium broke loose in pieces as soon as the water blast penetrated the deposits and were removed with the jetter truck. The PVC host pipe remained untouched.
