Technology – Fish Lift Tube

We have developed a hydraulic, no‑electricity batch fish lift that lifts fish over dams and weirs using only water pressure. The system is simple, reliable, and fish‑safe.

What we can share openly

• The system operates on a 5‑step cycle: attract, capture, transport, deliver, drain.
• It uses no electricity – only the existing water head.
• The fish transfer tube is made of HDPE (corrosion‑proof, UV‑resistant).
• It is suitable for head heights from 1 to 10 metres (higher on request).

Detailed engineering information

The following information is available to qualified organisations (water boards, government agencies, hydropower operators, engineering firms, and serious project developers) after signing a Non‑Disclosure Agreement (NDA) and providing basic information about your barrier project:

• Exact tube diameter recommendations per fish species and head height
• Water supply pipe sizing formulas and surge flow calculations
• Valve specifications (type, size, actuation)
• Cycle timing and hydraulic logic
• Materials sourcing (HDPE grades, seals, coatings)
• Installation drawings and concrete anchoring details
• Performance estimates (passage rates, cycle times)

Why we require an NDA

We have invested years of engineering and real‑world testing (including algae systems featured on CNN and Biodiesel Magazine) into this hydraulic fish lift design. To protect our intellectual property and remain competitive, we share detailed specifications only with genuine project partners who are willing to sign a standard NDA.

This is common practice in B2B engineering – and it ensures that you receive accurate, site‑specific advice, not generic brochures.

How to request detailed information

If you represent a water board, government agency, hydropower operator, or a serious project developer with a specific barrier, please:

1. Contact us via email: info@fishlifttube.com
2. Include – your organisation name, the barrier location, head height (metres), and target fish species.
3. We will send you a one‑page NDA.
4. After signing, we will share the relevant technical specifications for your project.

No obligation. Just professional dialogue.
