Drain Cleaning & HP Jetting
High-pressure jetting for blocked drains, sewer lines, stormwater systems, industrial pipelines and pre-rehabilitation cleaning.
Nationwide South Africa Coverage
HydroTrace provides this service across South Africa for residential, commercial, industrial, municipal and mining infrastructure clients. We support Gauteng, Western Cape, KwaZulu-Natal, Eastern Cape, Free State, Mpumalanga, Limpopo, North West and Northern Cape projects.
Technical Overview
HydroTrace uses high-pressure hydro jetting to restore hydraulic capacity, remove obstructions and prepare pipelines for inspection or rehabilitation. Jetting is a controlled cleaning process where pressure, flow and nozzle type must match pipe condition.

- Tree roots
- Sediment and sand
- Sludge accumulation
- Construction debris
System Problems
- Slow drainage
- Recurring sewer backups
- Stormwater flooding
- Odours

Full Technical Process
CCTV or Site Assessment
HydroTrace identifies blockage type, pipe diameter, material, access points and structural risk before cleaning begins.
Pressure Calibration
Jetting pressure and flow are selected according to pipe condition. Older clay, concrete, PVC and corroded lines require different cleaning strategies.
Nozzle Selection
Penetrator nozzles, rotating nozzles, root cutters, descaling heads and flushing nozzles are selected according to the obstruction.
High-Pressure Cleaning Passes
Controlled jetting passes remove debris, roots, grease, scale and sediment while restoring flow path.
Debris Flushing & Removal
Dislodged material is moved downstream or extracted to prevent secondary blockages.
Post-Cleaning CCTV Verification
A final camera inspection confirms whether the line is clean and whether structural defects remain.
Maintenance Recommendation
HydroTrace advises whether routine jetting, root management, relining or repairs are needed.

Drain Cleaning & HP Jetting Technical FAQs
Is high-pressure jetting safe for old pipes?
It can be, but pressure must be controlled. HydroTrace selects pressure and nozzles according to pipe material and condition.
Why clean before CCTV?
Debris, grease and sediment can hide defects and prevent the camera from travelling through the line.
Can jetting remove roots?
Yes, root-cutting nozzles can remove roots, but recurring root intrusion usually indicates pipe defects that may require rehabilitation.
