SADE defies the heights…
…by rehabilitating a reservoir using the Hydroclick® process.
Vendée Eau entrusted the Rennes Regional Division with the rehabilitation of a 5000m³ reservoir in La Roche-sur-Yon.
Dates: from 2 November 2021 to 17 May 2023
A vast project
This was a technical feat for the Civil Engineering-Special Works Agency, which was responsible for the interior rehabilitation of the water tower:
- Waterproofing of the tank by laying HDPE plates (Hydroclick® process)
- Repairs, by rope access technicians, to the reduced-access steel riser mains
And exterior junction and asbestos disposal works to the pipelines
Its co-contractor, VERTICAL, was in charge of the facility’s external renovation, which included stripping, waterproofing and sealing repairs to the dome.
Where there’s a problem, there’s a SADE solution
The rehabilitation of reservoirs using the Hydroclick® process is in perfect keeping with the French Government’s goals for water management, addressing one of three major challenges: to preserve the quality of water by improving storage and thus ensuring safe supply.
Spotlight on the Hydroclick® process
This technique consists in laying high-density polyethylene plates (4mm thick), which are specially designed to ensure optimal watertightness and resist extreme conditions. They guarantee the durability and reliability of a tank, ensuring safe storage of drinking water for more than 50 years!
