Safe and Efficient River Intake

Protection against Excessive Supply

Solutions > Intake in rivers

​​In river intake management, several challenges are crucial to ensure a constant and efficient supply, especially in extreme conditions. The proposed solutions approach the design with simplification for operation and maintenance.


Common situations

In natural river intake, the priority is to guarantee supply in dry seasons and to manage floods. Flat Gates are solutions to control flow, but their effectiveness depends on the ability of staff to adapt to abrupt changes. Other options, such as taking all the flow and then returning the excess, face challenges with floods that can block the control elements. Mobile Dam solutions also require manual operations, impacting their effectiveness depending on the staff's ability to avoid structural damage. In conclusion, adaptability to rapid changes is key in the design to ensure functionality after extreme events.

The equipment operation for the above situations can be exhausting, especially in watersheds with unseasonal flood events, which often occur during the night. In addition, the absence of flood events for extended periods can create a false sense that the constant presence of operators is not necessary. Hiring staff willing to work in remote and challenging locations compounds the problem.



Technical Challenge

​

The technical challenge is to design a safe construction site that manages design flow rates and is protected against overflows, without exclusive dependence on operators. Fast response to changes in level and flow, resistance to weather and vandalism are essential.

Our technical solutions focus on efficient and sustainable performance in time.

► Features

These solutions include civil works for small or medium-sized river intake, which include one or more gates controlled by floats and ballast weights, designed to maintain a specific downstream level defined by the user, according to the required flow rate. These devices open or close autonomously according to variations in the level of water in the channel, ensuring the downstream level constancy. The absence of motors and sensors contributes to the robustness and reliability of this equipment.


They enable set point changes to be made on the regulated levels if the customer requires it, either manually or with the automation of small devices inside the gate. This automation is focused on the management of the set point change, not on the adjustment operations of the gate itself in case of fluctuations in the water flow, a situation that will always continue autonomously by the gate's floats. This ensures efficient, trouble-free and reliable operation in severe and variable weather conditions.


►Tips about use

This solution includes equipment inspired by a simple hydraulic design, totally autonomous, robust and free of any mechanical complication, allowing it to adapt to the most severe working conditions.

Features

  • Guarantee of constant and safe inflow to the intake, independent of fluctuations in the river.
  • Guaranteed functionality in severe weather conditions and safety in case of blockages.
  • No electrical power is required for operation.
  • No solids are retained at the bottom of the canal.
  • Allows set point changes to adapt to operational changes (remote controllable).
  • Low and simple maintenance.


Tips about use

  • It can be motorized and remote-controlled, with small DC motors and solar panel, simplifying the set point changeover operation.
  • It requires knowing the flow curve of the downstream section to obtain the flow rate.
  • Requires some rubber sealing equipment to achieve complete leak-tightness.
