Totnes (UK)

In Totnes, Devon, an existing weir has been fitted with two Landustrie hydropower screws. Both screws can generate renewable energy for about 400 households. The screws are 3.7 metres in diameter. A fish passage is provided next to the installation, allowing fish migration to take place unhindered. The number and size of fish passing will be monitored here. The fish-friendly design of the screws also allows fish to pass through without damage.
