Briefing Guide: Drain and Sewer Descaling & Obstruction Removal

Things to consider when deciding to choose water jetting for Sewer and Drain Unblocking, Descaling and Obstruction removal service.

  • A good supply of potable water is required (Ideally a fire hydrant – for applications using water pressure up to 1000 bar we are able to use process grade water) 1.5 – 12 cubic meters per hour.
  • Size Range: Diameter from 100mm ID to over 2000mm ID may be treated using this remote control system.
  • We are able to remove grout or concrete from steel or cast iron pipes with multiple bends.
  • We are only sometimes successful at removing concrete from plastic pipes. If we are successful at clearing the blockage the pipe almost always requires re- lining.
  • We have cleared obstructions in sewers over 200m meters in length
  • We have cleared sewers which were entirely blocked with scale, without damaging the pipe material.
  • We own all our own equipment
  • A suitable area for laydown of plant (Van and trailer combination or truck options are typically 10m in length)
  • For best results; we prefer sewage flows are diverted or over pumped.
  • Waste water disposal: Normally after filtration to remove majority of solids, the water is pumped to downstream side for disposal.
  • Productivity: Sometimes water jets offer the only effective method of cleaning thus avoiding the costly replacement of drain or sewer.
  • Removed solids are normally collected recovered from manholes using our powerful vacuum equipment and placed into containers/skips. These are normally moved to disposal point via forklift or crane.
  • Our Plant is diesel driven and as such requires a well-ventilated area in which to operate.
  • Our diesel engine pump units are fitted with spark arrestor and chalwyn valve, suitable for use in Oil Refinery or other installations where volatile atmosphere may exist.
  • Our Plant should ideally be positioned adjacent to the work face. It may however be operated remotely over 100m from the work face under special circumstances.
