A simplified scheme of the key stages. Scroll to see the sequence.
Typical applications
- Removing blockages and silt deposits in sewers and storm drains
- Cleaning collectors, wells and reservoirs
- Preparing pipelines for relining and tele-inspection
- Milling hard deposits and roots
Things to consider
- For failing pipes the pressure mode is set after diagnostics
- Access to manholes/inspection points on the section is required

FAQ
Is high-pressure cleaning safe for old pipes?
The pressure mode and nozzles are selected for the pipe material and condition; video diagnostics is done first if needed.
What about hard deposits?
Mechanical or hydrodynamic milling is used — it removes mineral deposits and roots.
