The aim of this item is to improve water quality by creating a strategically placed sediment trap and / or bund to intercept run-off that currently discharges direct to a watercourse or freshwater drain.

The land must be within a diffuse pollution priority catchment or focus area (unless an endorsement has been obtained from the Scottish Environment Protection Agency) or a flooding target area.

You must combine this item with:

You must prepare a plan which must include a map of the relevant fields / steading identifying the location of the rural sustainable drainage system feature.

  • bund height must be less than 1.3 metres, unless designed by a qualified engineer
  • fencing must be provided to protect people and livestock.
  • only run-off which does not fall within the definition of slurry may be conveyed to a sediment trap / bund
  • run-off from pesticide handling or washdown areas must not be conveyed to a sediment trap / bund

You can claim:

  • excavate and form sediment trap – £10.50 per square metre
  • create bund – £7.20 per linear metre

The inspectors will check:

  • the location and extent of the sediment trap
  • the length of the newly created bund
  • bund height is less than 1.3 metres, unless designed by a qualified engineer
  • fencing is provided to protect people and livestock
  • only run-off which does not fall within the definition of slurry is conveyed to a sediment trap / bund
  • run-off from pesticide handling or wash-down areas is not conveyed to a sediment trap / bund
