Drain Cleaning & High-Pressure Water Jetting
High-pressure jetting and combination units for blocked and dirty pipe networks.
Dynamic clears and maintains pipe networks using high-pressure water jetting and combination drain-cleaning units. Jetting cuts through blockages, silt and build-up, restoring flow in stormwater, sewer and drainage assets.
What is high-pressure drain jetting?
High-pressure jetting drives water through a nozzle at pressure to cut through blockages, silt and root intrusion and scour the pipe wall. On a combination unit the dislodged material is recovered by vacuum rather than pushed further down the line.

What decides how a drain clean is run
Jetting a short stormwater line and clearing a silted culvert are different jobs. These are the things that set the unit, the nozzle and the time on site.
What is blocking the line
Silt, sand, roots and debris each need a different approach. If the cause is unknown, a CCTV run first avoids guessing.
Pipe size, type and length
The unit and nozzle are matched to the asset, from small drainage lines through to culverts.
Access points
Where the pits, manholes or openings are, and whether a truck can stand close to them.
Recovered material
A combination unit recovers what is dislodged by vacuum. The expected volume, and whether it has to leave site, affects the setup.
Traffic and public areas
Road and public-area works need traffic and site controls in place before the crew starts.
Planned or reactive
Scheduled maintenance programmes are planned around a network. Urgent blockages are worked in around what is available in the region at the time.
Benefits of using Dynamic
Restores flow
Jetting removes blockages, silt and root intrusion that slow or stop drainage assets.
Pairs with inspection
Cleaning is often combined with CCTV inspection to confirm pipe condition after works.
Planned or reactive
Supports both scheduled maintenance programmes and urgent blockages.
From a blocked line to a decision on the asset
Cleaning and inspection answer different questions, and each makes the other more useful. This is how the drainage work fits together.
High-pressure jetting
Jetting cuts through silt, roots and debris so flow is restored and the line can be inspected.
This service
Vacuum recovery
On a combination unit the dislodged material is recovered by vacuum at the pit rather than pushed further down the network.
Vacuum LoadingCCTV inspection
A drain camera records the condition of the cleaned line, including where each defect sits along the run.
CCTV Pipe InspectionsDefect assessment
The footage and report show what is wrong and where, so the asset owner is deciding on evidence rather than on symptoms.
Repair or maintenance decision
Where a defect has to be dug up, hydro excavation can expose the pipe at the recorded position without damaging the services around it.

Safety considerations
- High-pressure equipment operated by trained crews
- Traffic and site controls applied for road and public-area works
- Recovered material contained and removed

What to send us for an accurate quote
Each of these has a field in the quote form, and site plans, drawings, photos and tender documents can be attached. The more of it we have, the fewer assumptions sit in the price.
- The assetStormwater, sewer, culvert or pit, with its approximate size and length.
- What the problem appears to beSlow flow, a full blockage, silt build-up or recurring issues.
- Access pointsWhere the pits or manholes are. A marked-up plan or photos are ideal.
- Disposal of recovered materialWhether it has to be taken off site.
- Whether CCTV is neededBefore cleaning to find the cause, after cleaning to confirm the result, or both.
- Traffic control and timingWhether the work is on a road or public area, and the preferred date and hours.
Frequently asked questions
How does drain cleaning relate to CCTV inspection?+
Cleaning and CCTV inspection work closely together. A CCTV inspection can identify the cause and location of a problem before cleaning, and confirm the pipe is clear and sound afterwards. Many jobs combine both.
What pipes can you jet?+
The fleet handles a range of stormwater, sewer, culvert and drainage assets. The right unit and nozzle are matched to the pipe size and blockage type.
Does jetting just push the blockage further down the line?+
Not on a combination unit. The jet dislodges silt, roots and debris and the vacuum recovers it at the pit, so the material is removed from the network rather than moved downstream to cause the next blockage.
What information do you need to quote drain cleaning?+
The type of asset, its approximate size and length, what the problem appears to be, where the access points are, and whether recovered material has to be taken off site. If the line has not been looked at, a CCTV run is usually the cheapest way to avoid quoting blind.

What CCTV drain inspection tells you about an underground asset
A camera in a pipe replaces guesswork with a record. CCTV inspection reports the location, depth, length and type of a drainage asset along with the faults inside it, which is what makes a maintenance or repair decision defensible.

A combination unit carries jetting and vacuum capability on the same truck, so a drainage line can be cut clean and the material recovered in one operation. Water recycling extends how long a crew can work before refilling.
