Complete Tapping Service

What Complete Tapping Service does

Complete Tapping Service (CTS) is an Australian specialist field services company that performs under pressure tapping on water and wastewater mains, enabling connections, modifications, and maintenance on live pressurized pipework without interrupting customer supply. The company is headquartered in Keysborough, Victoria, and operates seven regional offices across Queensland (Brisbane and Townsville), New South Wales, Tasmania, South Australia, and Western Australia, with regional managers handling customer inquiries, quotes, and on-site project execution. CTS's core technology stack consists of two line stopping systems: its patented in-house AquaStop™ system for temporary shutdown of mains from 80mm to 500mm, and the imported Hydra Stop system used alongside it. The company is a subsidiary of the AVK Australia Group (itself part of the larger AVK Holding conglomerate), generates revenue through professional services on a quote-based pricing model (costs determined by project scope, pipe diameter, and location), and serves primarily water authorities (government utilities) and contractors, with secondary use cases in mining/industrial and building services. CTS holds approved-contractor status with all major Australian water authorities and complies with the WSAA Code of Practice, and in 2024 completed what is described as the largest under pressure tapping project in New Zealand, signaling incremental trans-Tasman expansion.
