Reservoir Working

Megget Reservoir – Shoreline Repairs

A considerable length of the shore line on the upstream face of the reservoir bank, close to the reservoir embankment’s mitre, had slipped into the reservoir and this project was to stablilise the slippage and reinstate the shoreline profile.

The works involved the construction of a hardcore road to access the underwater area of the reservoir suffering from slippage and subsidence where the reservoir bank joined the main reservoir embankment close to the dam’s north mitre. The slippage area was excavated to a depth of 3.5m at the lower end with the cut  infilled with rock armour which was subsequently re-covered with the excavated material. Once the rock armour had been covered and shaped to restore the shore-line profile, the temporary stone access road was removed.

GL’s works involved:

  • Cleaning off the reservoir bank vegetation
  • Form a stone access road to the area where the shore-line slippage had occurred
  • Cutting through the existing overburden and forming a wedge-shaped excavation 3.5m deep below the existing slipped bank level
  • Laying a geotextile membrane on the formation and covering the membrane with two layers of rock armour
  • Supply and placing of 2000t of rock armour
  • Replacing and re-grading of the 3300t of excavated material over the layered rock armour to the required shore-line profile
  • Remove the temporary access road to the reservoir and final reinstatement of the area
