Fish Lift Tube
 

Hydraulic fish passage – powered only by water

Dams and weirs block fish migration. Laws require a solution. But electric fish lifts are expensive, complex, and fail when power is lost.

Fish Lift Tube is different.
No electricity. No control room. No complex sensors. Just water pressure, a few valves, and a simple batch cycle.

How it works (5 steps)

1. Attract – Water flows through the tube; fish enter the capture chamber.
2. Capture – The lower gate closes, trapping fish inside.
3. Transport – An upstream valve opens; a surge of water pushes fish up the tube.
4. Deliver – Fish discharge above the dam or weir.
5. Drain – The system resets, ready for the next batch.

All driven by the existing water head – no pumps, no generators, no grid connection.

Why choose Fish Lift Tube?

• No electricity – Works anywhere, even remote sites. No power bills. No outage risk.
• Low maintenance – No motors, no electronics, no sensors to fail. Just valves and tubes.
• Fish‑safe – Smooth HDPE interior, no sharp edges, no high‑speed turbines.
• Grant‑friendly – Environmental agencies and water boards recognise hydraulic solutions.
• Proven principle – Based on decades of batch fishway research – now made simple and robust.
• Built to last – HDPE tubes and industrial valves – corrosion‑proof, UV‑resistant.

Who is this for?

• Water boards (waterschappen) – meet EU fish passage regulations without ongoing costs.
• Hydropower operators – comply with licences using a passive, reliable system.
• NGOs and foundations – cost‑effective fish passage for restoration projects.
• Government agencies – simple to tender, easy to install, no specialist operators needed.

What head range?

Fish Lift Tube works for low to medium head dams – typically 1 to 10 metres.
Higher heads? We can design a multi‑stage system. Contact us.
