CCTV Drain Surveys

Hydro Cleansing Limited have invested significantly in state-of-the-art CCTV technology to deliver our full range of CCTV services and capabilities.

Why choose us?

We operate one of the largest fleets of CCTV vans in the South East.  Our high performance systems each have HD colour cameras, enabling engineers to easily identify objects causing blockages and are able to survey pipe sizes between 50mm and 300mm in diameter and operate to distances of 500m in a single setup.

Our CCTV operators are trained and accredited to OS19X for piped drain and sewers and OS21X for bricked sewers.  These accreditations are a pre-requisite for all operators who prepare CCTV reports for long term records purposes for all the U.K. Water Plcs.

Upon completion of the CCTV drainage survey, our clients are provided with a full colour DVD and a comprehensive WinCan version 8 report alongside recommendations prepared by a fully qualified engineer.

Typically deployed to find and record faults within drainage systems, we can help prevent any failures in the system.  CCTV is used within the construction industry, at the point of site handover.  The engineer will carry out a comprehensive evaluation, producing a report on the sites drainage systems, verifying the integrity, cleanliness and operational effectiveness.  The report
is vital to the assured and complete handover of a building preventing
on-going disputes over liabilities, should systems fail.


Conditional & Connectivity CCTV Surveys

Conditional and connectivity surveys assess the internal condition of our drains and sewage systems unearthing any pipe collapses, rot damage or blockages.  Inspecting the structural condition means that any problems can be dealt with straight away and any future problems can be avoided.

Pre-adoption CCTV Surveys

Pre-adoption surveys are carried out by water authorities, builders, architects, developers and local authorities when buying assets which involve drainage systems.  It provides confirmation and security that the pipelines are in good condition, that no unknown environmental risks are being accepted and there are no hidden problems within the drainage systems.

Home Buyer/Seller CCTV Surveys

Pre-purchase house surveys are now required by most mortgage lenders, alongside giving peace of mind to the prospective property buyer.  This can be particularly relevant if the property is older, refurbishment has been undertaken, or if there have been construction activities in the surrounding area.


Push Rod Cameras

For pipes smaller than 2.25mm in diameter we use an advanced push rod camera system, which consists of a camera attached onto a rod, which can be manually navigated to identify problems.  This provides the same level of reporting, but is able to access narrow, smaller pipes.

Crawler Camera CCTV Drainage Survey Unit

A crawler unit drain camera is used for longer and larger pipe sections, is operated by remote control and has advanced pan and tilt technology.  The high performance CCTV drainage crawler camera system is supplied with 500m of Kevlar-reinforced cable and an auto self-leveling high definition (HD) colour camera.  Suitable for pipe sizes from 150mm (6") up to 525mm (20.5") in diameter.


Mega-Cam is another remote controlled CCTV camera system.  It has 4-wheel drive, colour CCTV inspection and suitable for pipes between 450mm and 2 metres+ in diameter.  This unit comes complete with built-in DVD, so all WinCan surveys are recorded and given to clients as a formal report regarding the condition and structure of drainage networks.
