WATER JETTING

"Insight Drainage sets the standard for high pressure jetting in the industry". We are constantly evolving both machinery and operational practices to meet the needs of our clients.

Insight has jetting units with the capabilities to clean 30ml tubes to 1200ml pipes running at 90 to 300 litres per minute water volume with 60 - 600 bar.

Insight water jetting equipment is engineered to be precision orientated.

Our jetting units are used to clean

  • Sewers
  • Storm water drains
  • Industrial pipe-lines
  • Culverts

Applications/Capabilities

  • Root-cutting
  • Heavy material removal
  • Fat deposit removal
  • High flow water-jetting

DRAIN SURVEYS

A drain survey involves a visual inspection of the pipe for condition assessment, fault detection and location, and quality of workmanship during the installation process. CCTV (closed circuit television) inspections are carried out by either pushing a camera along the pipeline, or by using a motorised tractor unit with a mounted pan and tilt head camera, to video and identify problems.

Insight 's CCTV operations use the very latest camera equipment for all their drain surveys. The company has advanced the use of the technology and includes the latest Ibak systems to allow immediate data transference to the client.

Drain surveys are used in:

  • Building consents
  • Property pre-purchase surveys
  • Stormwater and sewer pipeline location
  • Pipeline condition assessments
  • Blockages - cause and remedy
  • Council and/or property development of subdivisions/sign off for drainage

SUCTION

Insight pioneered the development of Hydro-Excavation (suction) in New Zealand. The company specialises in the removal of ground material to expose sensitive pipe areas such as gas pipes, and electrical cables. Insight's experience in rubble removal from most depths is second to none. Our machinery has the capabilities to lift sand, wood-chip, stones, water and sludge.

Insights vacuum-loading unit can handle debris materials as well as liquids. Both air and water can be used in the Hydro-excavation process.

Applications:

  • Hydro excavation
  • Catch pit cleaning
  • Heavy debris removal
  • Clean up of waste/sewer spills
  • Tank cleaning for pump stations and vehicles

SMOKE TESTING

Well functioning, effective drainage systems are an integral part of a healthy community and the conservation of a pollution free environment. Insight is regularly called upon to carry out smoke testing in the community. It is an effective process that identifies inflow sources to pick up cross connections and defects in sewer and storm water pipe lines.

The procedure uses a non-toxic smoke which is forced into the drainage systems. Where any smoke escapes via cracks, breakages, or incorrect connections it indicates a problem and identifies where the fault lies within the drainage system.

Generally :

  • Ground surface smoke indicates cracked or broken pipes below
  • Smoke from water pipes indicates an incorrect connection
  • Smoke coming from manholes indicates there is damage or unsealed waste water inspection chambers

The smoke used is environmentally safe. Our contractors inform local residents by letter whenever smoke testing is going to take place.


PIPELINE TRACING

Pipeline tracing is an effective method of pipe detection for situations where a camera cannot be used. Directional positioning of pipelines can be established using this method

  • No digging required
  • Can trace via gully traps
  • Can operate up to 5 metre depths
