Lake pipelines and drinking-water intakes.

A blocked intake cannot wait. We have done this work before: you can count on us.

A drinking-water intake supplies a whole municipality. When a screen clogs or a pipeline fails, every day out of service weighs on your network. We work on screens, pipelines and intake structures within the agreed time, and hand you a report your water department can file.

An intake that is down cannot wait.

The deadline

A blocked or out-of-service intake is a real problem for the supplier. We set a date with you and we keep it, planning the work to limit any interruption to supply.

Experience

Screens, pipelines, couplings, intake structures: our teams have done this work before. They know what they will find down there and how to deal with it, without trial and error on your time.

Depth

Many intakes lie between 25 and 69 metres. Below 40 metres, air is no longer enough: we dive on mixed gas, with the chamber on site.

Emergency. Intake blocked, mooring torn away: for emergency work on your structure to be possible, let us agree on it in advance. Write to us at subc@trsc.world and we will set the mobilisation time together.

A plan, a date, a report.

Before

We come and look at the structure. You receive a written work plan, including your network's hygiene requirements, a date and a price, fitted to your operations.

During

A daily update. Every dive is measured and recorded as it happens.

After

A report: the condition of the structure, what was done, what will need a further intervention and when.

Respect. In Switzerland, every dive follows the Ordinance on the safety of workers when working in pressurised environments (SR 832.311.12): safety concept (Art. 6), emergency and rescue plan, regularly drilled (Art. 7), treatment chamber on site as soon as the planned decompression exceeds fifteen minutes (Art. 21). In France, the Labour Code (Art. R4461-1 et seq.) and the orders of 14 May 2019; in Germany and Austria, the national accident-prevention rules. Our public liability insurance covers every job: the certificate comes with every offer.
