High-Pressure Water Jetting
When routine rodding or flushing no longer shifts grease, silt or compacted debris from a run, jetting is the next step in a managed drainage programme. This page sets out how a jetting instruction is scoped, what the site team needs to supply and when a camera inspection should follow. A reported symptom shapes the scope but is not a diagnosis.
Overview
Jetting cleans a pipe; it does not tell you why it blocked. The pressure used, the nozzle chosen and the state of the pipe all have to match the asset, or cleaning can do harm.
Our full service catalogue, including every individual service, is available across every listed sector and location. For one site or several, we agree the scope, access and programme around the buildings concerned.
What the work can include
An instruction can cover jetting of named, accessible runs, preparation beforehand, a flow check afterwards and a record of any restriction or damage revealed. The scope identifies the run, the waste handling and whether inspection follows, with what is handed over or tested at the end. Repairs, design, testing or replacement are separate unless included.
At the end the client holds a record of the run jetted, how waste was handled and whether follow-up inspection is recommended, with any limitation, interface or next action noted.
Important decisions
The key judgement is whether jetting should be followed by CCTV or a repair assessment. Make it with the site's operating limits and the client's approval route in mind, so follow-on work can be authorised without a wasted visit.
Before we visit
We ask for the pipe size and access, known defects, blockage frequency, any contamination, who occupies the area, the water source and the disposal route. For an estate, list each site separately and keep asset references consistent so runs on different buildings are not mixed up.
The size and access of the run, its blockage record, known defects, water supply and waste route are the essentials. Say at the outset whether the run should be inspected once it is clean.
How the work proceeds
The run and its risks are assessed, the cleaning method chosen to suit it, the agreed section jetted, flow confirmed and any defect or limit reported. The record of the run, the waste handling and the inspection recommendation gives the client what is needed to decide on CCTV or repair.
What affects cost and timing
Access, run length, the nature of the deposits, water and waste handling, traffic control, work outside normal hours and any preparation for a subsequent survey all affect price. For a managed site or estate, give the working window, the access contact and any shutdown constraints that apply to jetting.
Sector and property applications
Office blocks, schools, retail units and industrial premises each need jetting coordinated around where equipment can be set up, how waste is removed and how occupied areas are protected. The sector directory places the requirement in the context of each building type.
Local coverage
Our coverage takes in Northumberland, Tyne and Wear, County Durham and Tees Valley, including Berwick-upon-Tweed, Alnwick, Morpeth, Hexham, Newcastle upon Tyne, Gateshead, Sunderland, Durham, Darlington, Hartlepool, Stockton-on-Tees, Middlesbrough and Redcar and Cleveland. Estate clients should record each site's jetted runs, waste handling and inspection recommendations separately. Browse the locations.
Frequently asked questions
Does jetting deal with root growth?
It can clear roots that are within reach, but cutting them back leaves the joint they entered through unrepaired, so they return. An inspection afterwards is usually needed to choose between repair and relining. For an estate, hold each site's run, waste and inspection record separately so the next decision is clear.
Is there a risk to older pipework?
There is, where the pressure, nozzle or technique is wrong for the pipe's condition. The run, its material, known defects and access should be assessed before the method is fixed. Where the work touches occupied areas or operations, agree access, shutdowns and contractor handovers before it is scheduled.
Does a camera survey come with the jetting?
Only when the instruction says so. Cleaning and inspection answer different questions; a post-clean survey is added where a condition or repair decision depends on it. The completion report states what was included, what could not be done and what follow-up is needed.
How is the water and debris from cleaning dealt with?
Recovered solids and wastewater are contained and removed under the method agreed for the job. The scope names the water source, the disposal route, controls for contaminated material and any access limits. Planned programmes should use the findings to decide whether further jetting or related repairs are needed.
Knowledge and guidance
For the decision on whether cleaning should be followed by inspection or repair, read what causes recurring drain blockages and what CCTV drain surveying involves. The site assessment applies that guidance to your building or estate, with operating duty, access and the approval route taken into account.

Contact Black & White Facilities with the site or estate, the runs concerned, any records of previous cleaning or inspection and the operating constraints. We can then set out the client interface and scope without assuming a response time or a result.
