Various Fish Passes

Llandaff Fish Pass

The contract involved the construction of a 15m long larnier fish pass in the existing Llandaff Weir.

The works were adjacent to a comprehensive school and a busy public footpath known as the Taff Trail through a busy local park.. Within the proximity of the site Japanese knotweed was present

What We did

  • Created temporary blockstone and clay bunds to keep construction dry
  • Creation of access ramp that allowed footpath to remain
  • Constructed settlement pond
  • Worked pro-actively to mitigate costs when work carried into second season
  • Developed slotted fabrication method, allowing greater construction tolerance

How it was successful

  • Temporary bund worked during excessive rainfall (greater than CE events)
  • Working method avoided removal of knotweed
  • Steelwork fitted ahead of programme with no off site adjustments
  • Zero complaints from public
  • No accidents, incidents or environmental incidents

Brecon Fish Pass

This 15m long larinier type fish pass constructed on the River Usk was located in an environmentally sensitive area.

Access was gained through a 400m track constructed through a golf course.

What We did

  • River bed material re-used for infills in golf course
  • Liased with EA and anglers and carried out fish rescue, during installation of temp works

How it was successful

  • No material taken off site - 100 % reuse
  • Work started late summer yet sill completed before working constraints were enforced
  • Zero Complaints
  • Zero accidents or incidents

Treforest Fish Pass

Located on the River Taff in Treforest located in a constrained location both for construction and access.

What We did

  • Successfully constructed all in-river sections of the new fish pass.
  • Completed an impressive structure and created a landscape with great improvements to the original appearance

How it was successful

  • No complaints from the local garage owner or local residents.
  • Successfully worked with the Designer to develop a constructable scheme despite time, space, environmental and budgetary constraints.

Hampton Court Fish Pass

Located on an existing weir on the River Lugg, this 20m long larinier type fish pass was located in an environmentally sensitive area.

What We did

  • Constructed a 500m long access track across grazing land
  • Sourced existing masonry stone to match existing
  • Developed programme to maximise reuse of formwork - saving 2 weeks
  • Negotiated with land owner to reuse material

How it was successful

  • Constructed on time within budget
  • Zero complaints
  • No accidents or incidents
  • No material taken to tip - 100% reuse

Pontymoel Fish Pass

Located on the River Llwyd, adjacent to a Grade II Listed aqueduct, the fish pass is in an environmentally sensitive area that required access via temporary track. How it was successful

By submitting the Land Drainage Consent early, it enabled us to go into the river within three weeks, which allowed the major works to be undertaken prior to pour weather.

Ian was an integrated part of the planning process in determining the temporary access track and working platform arrangements.
