High Pressure Water Jetting

High pressure water jetting is an effective cleaning technique in pipes from 3/4” (19mm) to 48” (1200mm) and for the following applications:

Removal of compacted or loose debris in drains, sewers and culverts.
De-scaling of water mains.
Cleaning and flushing process pipe work. Interior and exterior cleaning of storage tanks. Restoration of painted or corroded structures.
Cleaning heat exchangers and condensers.
Removal of oil and grease from production areas.

Water is pumped through a reinforced hose and is converted into fine jets by a nozzle. The nozzles vary in design and application. They can propel the hose more than 300ft along a drain run and, at the same time provide a scouring action which de-scales and cleans the pipe wall. Other nozzles incorporate a powerful forward facing jet to clear obstructions.

Using Southern Drain’s expertise plus a range of adjustable flow-rates and pressures, deposits are efficiently broken up and flushed from the drains. Our jet power pump units vary from trailer mounted to lorry mounted producing a water flow rate range from 9 gallons per minute to 70 gallons per minute.

This combines with a pressure range from 1000 to 12000 PSI. These combinations will effectively clear blockages from soft silt to concrete. Gratings and Safticurb gullies are cleaned by attaching a lance gun to the jetting hose.

A specially designed pump can be attached to the jetting unit to remove water or small debris from manholes to surface level.
