The ULMA Engineering and Product Department has developed this specific solution for this project, which required a response to the problems of dirt and maintenance of pipes and trench drains.

These channels with built-in slope are the only ones on the market with a real slope of 2.5% which, thanks to their marked slope, provide greater hydraulic capacity, and resolve the slope limitations that can be found in some places.
After an analysis it was identified that the solution could consist of a channel of greater hydraulic capacity, incorporating a slope of 2.5%.

ADVANTAGES:

• Hydraulic capacity -100 l/s in 20 ml. * Study conducted by the Universitat Politécnica de Catalunya.
• Self-cleaning effect that allows the inside of the channel to remain clean at a low flow rate (from rainwater). It obtains a greater capacity to remove the sediment that can accumulate during heavy rains. This leads to a reduction in the need for maintenance.
• Possibility of installing up to 40 ml. It is possible to install two sections of 20 metres each, with a single water outlet.
