ULMA's Drainage Solutions Installed in Saint-Zacharie

Situated at an elevated vantage point above its neighbouring villages, Saint-Zacharie has acquired notable recognition for its lofty altitude, prompting whimsical tales regarding the possibility of touching angels' feet. However, setting aside these fanciful narratives, ULMA explains how they assisted in devising a drainage solution characterised by superior hydraulic efficiency, all while upholding the aesthetic appeal of the locale.

Technical advice and hydraulic calculations

ULMA first carried out hydraulic study using their Optimal Drain software to calculate the behaviour of water in the channels. By doing so, they can optimise the cost of the channel lines by selecting the channel best suited to each project.

Having completed this study, and thanks to the collaboration between the project's construction manager and ULMA's Technical Department, it was decided that the best solution was to install MultiV+ Channels with single-slot grating.

Optimized V-section for improved hydraulic efficiency

MultiV+ channels have a technical feature that sees them achieve a higher speed at low flow and increased capacity in extreme flows.

Their V-shape allows water to drain more quickly, meaning the force of the water when travelling through the channel is capable of moving sediments, generating a self-cleaning effect.

The smooth finish of the channel's interior helps the water to glide better, which improves the system's evacuation capacity.

Minimal visual impact

The installation of single-slot gratings is particularly popular in urban areas like this central street in Saint-Zacharie.

When working in environments like this, installing unattractive grating can be an issue that negatively impacts the visual finish of the facility.

It was for this reason that the decision was made to install a hidden single-slot grating: it leads to better aesthetics and ensures the drainage system doesn't affect the landscape.

Take a look at the photos. Can you see the straight line in the paving? The drainage system is installed underneath it, combining the system's hydraulic efficiency with aesthetics.

As you can see, this solution doesn't overshadow what should really shine, which is the scenery of Saint-Zacharie.
