Environmental Techniques was established in 1992 to provide trenchless drainage inspection, cleaning and rehabilitation throughout the United Kingdom and Ireland, with offices in Northern Ireland, Scotland and the Isle of Man.

Our fleet of inspection vehicles provide surveying services for wastewater network assets including CCTV surveys, sonar surveys, manhole mondition and dimensional surveys, dye tests and impermeable area surveys. Our jetting rigs provide cleaning, unblocking and degreasing of sewers and culverts. We also provide services for pipeline rehabilitation including CIPP lining, localised patch repairs and GRP lining.

In 2017 Environmental Techniques became part of the Aegion Corporation which recently in 2024 rebranded as Azuria Water Solutions. As part of Azuria Water Solutions, Environmental Techniques have further developed their technical capabilities through the use of carbon fibre reinforced polymers and drone survey technology.

Environmental Techniques continue to push the boundaries of CCTV surveys and investigation through the use of drone and LiDAR technology. Environmental Techniques work closely with clients to understand the needs in advance of carrying any work out. With close liaison and good communication, Environmental Techniques are able to provide savings and benefits to clients on a regular basis.
