River Itchen Eel Screens

Barhale was contracted by Portsmouth Water to design and build
appropriate infrastructure at its abstraction intake on the River Itchen.
The scheme aimed to align the structure with the recently imposed
England and Wales Regulations (Eel), whilst also screening for Brook
Lamprey.
To achieve this, 4No. S1800 Hydrolox screens were retrofitted to the
existing intake structure in place of the existing raked course bar
screens. This required structural modifications and an additional
cantilevered 12m walkway over the river for maintenance access.
