Project type: Weir removal and habitat restoration
Location: Ravensbury Park, Morden, London
Length: 30m
River: Wandle
Client: The Wandle Trust
Installation date: September 2012
Project Brief
A stepped concrete weir on a side channel of the River Wandle created a complete barrier to fish.
Cain Bio-Engineering reconnected the river by breaking out the concrete weir and stabilising the bed using sweet chestnut post flow attentuators and locally sourced large gravels.
We also replaced the dilapidated oak boarding with a a geotextile revetment which is designed to fully vegetate.

Location: Stapleford, Salisbury, Wiltshire
Length: 55m of geotextile revetment
River: Wylye SSSI
Client: Balfour Beatie, Mott MacDonald, Highways Agency
Installation date: October 2011
Project Brief
This project is located on the River Wylye adjacent to the A36 west-bound carriageway. River bank erosion was threatening the stability of the highway.

Project type: Mill Leat Bypass
Location: Arborfield
Length: 200m of new bypass channel
River: Lodden
Client: Environment Agency
Installation date: 2011
Project Brief
On the River Lodden at Arborfield, historic mill and weir structures prevented fish passage, and had impounded the river for 4km upstream.
A combination of civil engineering and soft engineering techniques were used to design and build a 200m weir bypass channel to reconnect 25km of the River Loddon.

Project type: Mill leat and carrier restoration
Location: Hampshire
Length: 500m
River: Upper Itchen
Client: Private landowner
Installation date: 2011
Project Brief
At this historic milling site, three off-take side carriers provided the opportunity to reconnect a perched mill leat with the main river Itchen. Because of a relatively steep fall from the mill leat down to the main river, the gradient had been previously stabilised using concrete weirs to create amenity impoundments with decorative waterfalls.
