Given the low-head nature of the majority of our rivers, and a history of fish-protection issues preventing micro-hydro developments, the potential for this technology was immediately obvious. Mann Power became the Archimedean Screw generating specialists in the UK.

As a newcomer to British rivers, it was essential to demonstrate to environmentalists and statutory bodies that the positive results of tests carried out on undertaken by Mann Power has extremely positive implications for the economics of micro-hydro in the UK. Literally hundreds of sites – previously written-off for hydro – are being revisited for development and the cost of installation has been greatly reduced.

Most positively of all, the advent of the Archimedean screw means that fish-protection and micro-hydro need no longer be mutually exclusive.
