Trusted Micro Hydro Energy Solutions in the UK
Established in 2005, Freeflow 69 has emerged as a leader in micro-hydro engineering, combining historical technologies with modern innovations. Our expertise lies in designing and manufacturing stainless steel water wheels and Archimedes screws tailored for renewable energy generation. With over 18 years of experience, we specialise in custom solutions for domestic, commercial, and industrial clients seeking sustainable power systems. Our team guides projects from initial consultation through installation and commissioning, ensuring optimal performance and minimal environmental impact. We prioritise fish-friendly designs and utilise corrosion-resistant materials for long-term reliability.Our hybrid systems, including the patented Ocean Hydro Electricity Generator, deliver 24/7 power generation capabilities. We provide comprehensive feasibility studies, site assessments, and after-sales maintenance contracts to maximise client returns. Our associate manufacturing partner, Able Engineering, ensures precision fabrication of all components in the UK. We maintain rigorous quality standards across all projects, from small-scale domestic installations to large commercial ventures. Our commitment to innovation is demonstrated through continuous research into tidal, wave, and river energy technologies.

Services
Poncelet Water Wheel
Our Poncelet water wheels utilise traditional engineering principles adapted for modern renewable energy needs. Available in standard 2m diameter configurations, these systems operate efficiently with water heads between 1.5-2.5m. Manufactured from corrosion-resistant stainless steel, each wheel delivers 1.7-3kW output while maintaining ecological compatibility with aquatic environments.
Archimedes Screw
Modern reinterpretations of ancient Greek technology, our Archimedes screws convert water flow into electricity with exceptional efficiency. Designed for sites with up to 15kW capacity requirements, these systems combine historical principles with contemporary materials for reliable, low-maintenance operation.
Water Wheel Design
We create bespoke water wheel solutions including overshot, breastshot, and Zuppinger configurations. Our engineers develop hybrid designs tailored to specific site conditions, optimising energy capture while minimising environmental impact through computational fluid dynamics analysis.
Ocean Hydro Electric Generator
Our patented OHEG technology combines tidal turbines with accumulator systems for continuous power generation. Modular designs allow deployment in various marine environments while maintaining structural integrity against oceanic forces.
Eel Passes
Ecological enhancement features integrated into hydro systems to facilitate fish migration. These passages maintain aquatic ecosystem connectivity while ensuring operational efficiency of renewable energy installations.
