ULMA assists engineers and planners in selecting the most cost-effective drainage solutions while maximising hydraulic capacity.

The Engineering Office follows a structured four-step process to provide clients with certainty and efficiency in their projects. With expert guidance from the technical team, the most suitable drainage solution is identified, ensuring optimal performance and cost-effectiveness.

The Four-Step Process

1. Project Analysis
Each project is thoroughly examined to assess its specific requirements and characteristics.

ULMA Study: Rainfall information, supply areas, land slopes, line lengths, runoff coefficient of surfaces.

2. Hydraulic Calculations
Hydraulic calculations are performed based on key parameters such as height, width, section dimensions, and load classes.

These calculations are conducted using Optimal Drain, ULMA’s in-house software, which ensures that every element—channels, gratings, accessories, outlets, and slopes—is selected for maximum efficiency in both drainage capacity and cost.

3. Comprehensive Documentation
A detailed report is provided, justifying all design choices with reference to dimensions, water flow, filling percentages, flow rates, and velocities.

• Technical datasheets • Plans/details in DWG format • Details adapted to your project • BIM • DOP • DAP • Quality control certificates
4. Construction Support
Assistance continues beyond the design phase, with expert guidance offered to project managers throughout the installation process, ensuring seamless execution.
