Water & Wastewater Utility Diving Services

TUF International provides commercial diving services to water utility companies, municipal authorities, and infrastructure contractors responsible for drinking water and wastewater treatment assets. Our teams inspect, maintain, and repair treatment plant infrastructure — including reservoirs, clarifiers, filters, and pumping stations — without drain-down, eliminating the cost and disruption of taking assets offline. All operations across 154+ countries comply with drinking water and environmental standards.

Diving operations in potable water environments are governed by strict material and contamination standards. All tools, equipment, and repair materials that come into contact with drinking water must be compliant with WRAS (Water Regulations Advisory Scheme) approval requirements, and divers themselves must follow hygiene and decontamination protocols that prevent the introduction of biological or chemical contaminants into treated supply systems. In wastewater environments, additional biological hazards — including hydrogen sulphide, methane, and Leptospirosis — require gas monitoring, medical surveillance, and HSE-compliant confined space procedures throughout every operation.

TUF International's IMCA-aligned commercial dive teams are fully equipped and trained to manage all of these requirements — delivering safe, compliant water and wastewater utility diving services, treatment plant inspection, confined space diving, and underwater structural repair across drinking water treatment works, wastewater treatment plants, pumping stations, and storage reservoirs worldwide.
