Andidrain specialise in carrying out high quality investigative surveys of wastewater infrastructure, including drains, culverts and chambers.
We operate a large fleet of CCTV units using the latest equipment and carry out man-entry confined space survey work, using our own experienced and qualified personnel.

CCTV Surveys

Andidrain has established an enviable reputation for the quality of CCTV survey work.

Our fleet of units are maintained to exceptionally high standards and utilise reliable, up-to-date technology combined with skilled and experienced operators and processing staff.

As well as fully equipped self-contained CCTV vans, we have also developed and operate a tracked rough terrain unit incorporating a 500m long reel, allowing surveys to be undertaken in remote locations.

We use the industry leading WINCAN reporting system, where survey footage can be embedded, to produce accurate, detailed and easy to understand reports. We even provide the software to enable customers to view surveys and reports on their own PC’s.

Andidrain were one of the first organisations in the UK to successfully publish data using the Highways Agency Drainage Data Management System (HADDMS).

Surveys can be presented in hard copy and in a variety of digital formats to suit individual requirements.

Confined Space Surveys

With twenty years experience, Andidrain are one of the UK’s leading experts in the provision of Confined Space Entry teams.

We can either carry out surveys directly ourselves or provide the support to enable clients’ engineers to undertake their own inspections.

Our experienced site teams are Confined Spaces qualified up to High Risk City and Guilds standard, with additional training in the use of Breathing Apparatus (B.A.) and Confined Space Rescue and Recovery.

Andidrain have worked in a range of challenging environments, from highways and tidal works through to chemical manufacturing facilities and refineries.


“Over the last 5 years I have found Andidrain to be reliable, flexible and easy to do business with.

They have adapted to the ever changing demands in the industry and provide a quality service, whilst always looking for improvements and efficiencies.”

Tim Shepherd Programme Development Manager

“Andidrain emptied and cleaned one of the AD digesters, a liquid feedstock vessel and a lagoon; I was impressed with the professionalism of the team, along with the quality of work carried out. I would have no hesitation in recommending Andidrain for digester cleaning.”
