Drain desilting removes settled mineral deposits from a defined pipe run. Jetting is planned with a recovery point so loosened silt is removed from the network. Rapid recurrence can indicate a continuing sediment source or a low section that needs further investigation.
Drain Desilting
Drain desilting to remove settled sediment through controlled jetting and recovery, with advice on recurring silt and further inspection.

Settled sediment and recovery points
Silt tends to collect where flow slows or a pipe has a low section.
Jetting and controlled sediment recovery
Before desilting starts, we establish the section to be cleaned, connected flows and a suitable recovery point.
Settled sediment and recovery points
Silt tends to collect where flow slows or a pipe has a low section. Jetting loosens the deposit and moves it towards a suitable recovery chamber, where suction removes it from the system. Pumping free water alone can leave the sediment bed intact. Pipe condition and access determine which tools can be used safely.

Jetting and controlled sediment recovery
Before desilting starts, we establish the section to be cleaned and the connected flows. Recovery is arranged so loosened material is not driven into another restricted or occupied part of the system, and waste handling reflects any contamination picked up from the catchment.
Condition checks after desilting
Once sediment has been removed, we state how much of the pipe was cleaned and whether the wall is visible for inspection. Low spots, damaged connections or continuing construction runoff can explain rapid recurrence. Desilting removes the deposit; it does not correct poor fall or repair damaged pipework.
If a later CCTV survey is needed, any section that remains obscured is identified so the inspection coverage is clear.
Drain Desilting: common questions
Is desilting the same as removing grease?
No. Mineral sediment and grease behave differently and need suitable methods.
Does pumping water remove all the silt?
No. Settled deposits can remain after free water is pumped away.
Why might silt return quickly?
Continued incoming sediment, low spots or damaged drainage can cause quick recurrence.
Will silt be pushed into the next drain?
The plan includes a controlled recovery point to remove loosened material from the network.
Should a survey follow desilting?
It may be needed where deposits previously hid the pipe wall or a repair decision depends on condition.
