Concrete removal at the Ibrox Stadium

The Colus Specialist Projects Team has been working at the Ibrox Stadium, the home for the Scottish Champions ‘The Rangers’, at their new museum, removing 12m of concrete running up to 100% in a 450mm pipe.

Failed CIPP liner removal

How to remove a failed or collapsed CIPP liner? Simply with High Pressure Water Jet Cutting.

In this video a failed, partially uncured, liner with a massive wave (shark fin) at the bottom was removed from a 450mm (18”) host pipe with the Sewer Robotics WJ180 Water Jet Cutting Sewer Robot.

California calcium removal

The calcium in this coated VCP 12″ sewer pipe was more than half the diameter of the inside of the pipe and had formed a “pipe in a pipe”. Pacific Sewer Maintenance broke that internal calcium structure into smaller manageable pieces for easy removal with a jetting truck. 600 feet of pipe back to 100 % capacity.

Removing tuberculation before UV-lining

Years of hydrogen sulfide gasses accelerated the corrosion of this 300mm (12”) sewer pipeline, leaving it heavily tuberculated with the upstream manhole in a very bad shape.

No problem for Daito CO., LTD., who accepted the challenge with a smile.

Fatberg removal from UK sewer pipelines

The enormous fatberg was found in UK sewers was approx. 330ft in length and 9.5″ (100m long and 25cm thick) and taking up half the flow capacity of the pipe. The gruesome fatberg was one of 30,000 sewer blockages a year in East Anglia – 80 per cent of which are caused by wipes and fats.

Concrete removal in Italy

After various failed attempts of different nozzles and cutters, Sewer Robotics was invited to remove the concrete that has been blocking this 400mm sewer main line for the past 10 years.

Calcite removal from clay pipe

Years of mineral deposits leaving a layer of calcite and narrow joints inside this 200mm (8”) clay sewer main pipeline.

Water jet cutting applies a high pressure low volume water blast from a special designed crawler with camera and pan and tilt nozzle to remove the calcium without adding damage to the host pipe.

Removing pipe tuberculation (scaling)

Scaling and tuberculation reduced the flow in cast iron pipelines.

The pipe flow was restored with a water jet applied from a robot with camera and rotary nozzle with 500bar (7,250psi) water pressure.

Water jetting roots at pipe joint

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.

Sewer Wax removal after factory fire

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.

Water jetting hardened grease and fat

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.

25 cubic yards aggregate concrete blocking multiple lines

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.
