SaniTube® receives KTW-BWGL certificate of conformity

Greater safety for the trenchless rehabilitation of drinking water pipes

The rehabilitation of existing drinking water pipes presents network operators and planners with growing challenges: alongside technical renewal, drinking water hygiene, operational safety, construction time and cost-effectiveness play a particularly crucial role.

The KTW-BWGL certificate of conformity certifies that the SaniTube® process from Amex Sanivar is suitable for drinking water hygiene. This marks an important milestone for its use in the trenchless rehabilitation of drinking water pipes in the DN 80 to DN 450 range.

This means that our system is not only recognised under the French ACS and the Austrian OFI standards, but also holds the highest German drinking water approval.


Close-Fit technology without resin or curing

SaniTube® is based on Close-Fit technology. The liner is pulled into the existing pipework and, under pressure, moulds itself tightly to the existing, deteriorated pipe wall. This creates a precisely fitting liner that leaves no annular gap – even in bends – and therefore causes no pressure loss. Furthermore, no resin impregnation, thermal curing or reversion is required.

This eliminates a key processing step which, in resin-based methods, can require additional technical equipment and process control. This simplifies installation and enables an efficient construction process.

Long insertion lengths, fewer interventions

Depending on the project conditions, SaniTube® allows insertion lengths of up to 2,000 metres at insertion speeds of approximately 10 to 35 m/min. This means that longer sections of pipework can be rehabilitated with only a few excavation pits. This reduces disruption to the existing infrastructure and significantly shortens construction times, whilst minimising disruption to local residents and traffic.

Furthermore, the system is designed for applications up to PN 16. The mechanical connection to the pipework network is achieved using specially developed, tension-secured SaniGrip flange couplings® PN16.

Drinking water hygiene meets efficient rehabilitation

The combination of KTW-BWGL compliance certification, close-fit technology and efficient installation makes SaniTube® a modern solution for the trenchless rehabilitation of existing drinking water pipes.

Where open-cut construction reaches its limits, trenchless rehabilitation demonstrates its strengths. SaniTube® combines drinking water hygiene safety with efficient installation and minimal disruption to the existing infrastructure, thereby offering a forward-looking alternative for the rehabilitation of drinking water pipes.
