CCTV Drain Surveys near you

British drainage surveys are coded rather than described. WRc publishes the Manual of Sewer Condition Classification, now in its fifth edition and universally shortened to MSCC5, and its codes are used alongside the European coding standard BS EN 13508-2. Every observation the operator logs — a fracture, an open joint, root ingress, encrustation, a deposit, an intruding connection — is recorded as a code at a measured distance from the start manhole, which is why two surveyors working properly on the same pipe should produce broadly the same document.

From those codes come the grades that actually drive decisions. WRc describes how the internal condition grade and the operational grade for each pipe section are determined from the MSCC codes in accordance with its Sewerage Risk Management approach, and states that these are scored 1 to 5 where grade 5 is the worst condition. Two grades exist because a pipe can be structurally sound but operationally useless, or structurally poor but currently flowing perfectly well, and the two problems have different remedies and different urgencies.

When you commission a survey, ask in advance for the coded observation schedule, the grades per section and a drawn plan with manhole references, not merely a video. If a surveyor cannot say which manual and which edition the report is coded to, you are buying footage rather than an assessment, and no insurer or engineer will be able to use it.

A camera is excellent at condition and layout and poor at watertightness. It will show you a fractured barrel, a root mass, a dropped invert, a rat run or a pipe laid backfall. It will not, on its own, tell you whether a hairline crack is leaking, because water leaves a pipe under load and a survey sees the pipe empty. That distinction matters most in subsidence and damp investigations, where the whole question is whether water is escaping into the ground.

This is why Approved Document H, the 2015 edition, tests new drainage with pressure rather than pictures. For below-ground gravity drains and private sewers up to 300mm diameter it describes a water test in which the system is filled to a depth of 5 metres above the lowest invert in the test section and a minimum of 1 metre at the highest, left about an hour to condition the pipe, then held for 30 minutes with the level topped up, and losses per square metre of surface area must not exceed 0.15 litres where the test length is pipeline only, 0.20 litres where it includes manholes, or 0.40 litres for manholes and chambers alone. Nothing a camera does replaces that.

The other blind spot is connectivity. Approved Document H expects that, where separate drainage systems are provided, connections are proven to be made to the correct system — a check that needs dye or tracing rather than the camera, and one worth asking for explicitly if your property has separate foul and surface water drains and an unexplained smell or a pollution notice.

In England and Wales, pipes serving more than one property and the lengths running beyond a single property's boundary to the public sewer passed to the water and sewerage companies in the 2011 adoption of private sewers, which is covered in detail in the sewer and drain guides on this site. The practical consequence for a survey is straightforward: if the fault lies beyond your boundary or in a shared run, the company should be investigating it, usually with its own camera, at no charge to you.

So the sequence is to ring your sewerage company first, describe the symptom, and let them establish whether the defect sits on their asset. Commission a private survey when they have confirmed the problem is inside your boundary and serves only your property, when you need a document for a purchase or an insurance claim, or when you want an independent opinion on work someone has quoted for. Scotland and Northern Ireland did not go through that transfer, so ask Scottish Water or NI Water where their responsibility starts rather than assuming the English position applies.

Survey pricing follows access and length more than anything else. The variables are how many chambers there are and how easy they are to lift, how much of the system has to be cleaned before a camera can see anything, the total run length and how many separate branches you want covered, whether tracing and depth plotting are included, whether dye or connectivity testing is needed, and how much reporting you are buying — a coded schedule with grades and a drawn plan takes office time that a raw video file does not. A survey bundled into a jetting visit is usually cheaper than one commissioned on its own, and a purchase survey with a formal written report costs more than a diagnostic look.

LokalMatch is the introduction and nothing more. Describe the drainage problem once, say whether you need a report for a purchase or an insurer, add your postcode, and drainage firms covering your area contact you directly. Using LokalMatch costs homeowners nothing; the pros pay for the requests that reach them. LokalMatch does not carry out surveys, has no say in what anyone charges, and does not vet, rank or recommend the firms that reply, so asking which coding manual the report follows and what the deliverables will be is a question for you to put to each of them.
