Inverness Flood Relief Phase 1 & 2

These works comprised the first two phases of the overall South West Inverness Flood Relief Channel project involving the upstream interception of storm water flows from five watercourses with the construction of 2km of open and culverted channels which ultimately discharge into the River Ness via the Holm Burn.

The main elements of the Phase 1, downstream works were on the Holm Burn and  included:

  • Construction of a fish pass and settlement pools
  • Widening of the Burn watercourse, with the formation of bunded ‘wet ledges’, and the installation of Pozidrain and erosion mat burn liner
  • Construction of a new vehicle access bridge and the relocation of a further bridge to enable fishermen access
  • Extensive rock armouring where Holm Burn discharges into the River Ness.

Phase 2 comprised the construction of a new flood relief channel which included:

  • 1km of 8m wide, fully lined open-cut channel
  • 400m of 4m x 2m precast concrete box culverts, installed up to 6m deep
  • Sediment basin and outfall arrangement into the Holm Burn.

Significant efforts were made to minimise any environmental impact of the works with extensive consultation and discussions with local stakeholder interest groups including SEPA, landowners, fishing associations etc.
