Ditch Checks

(Call for a Quote)

Filtrexx® filter soxx are used for ditch checks in stormwater drainage channels to slow concentrated directional flow velocity of stormwater runoff.

Ditch checks reduce gully erosion in ditch bottoms and remove sediment and soluble pollutants present in stormwater runoff.

Description

Filter Soxx used for ditch checks

  1. Provide a porous physical barrier perpendicular to concentrated stormwater flow
  2. Are designed to reduce and disperse runoff energy
  3. Reduce erosion by slowing runoff velocity and dissipate concentrated stormwater runoff flow
  4. Trap sediment and soluble pollutants by filtering stormwater as it passes through the ditch check and by water temporarily ponding behind the ditch check.

Ditch Check Soxx Installation

  1. Ditch checks should exceed the width of the channel by at least 1.2M on both banks to ensure water flows through and over the soxx and not around it.
  2. The centre of the ditch check should be at least 150mm lower than the sides of the channel.
  3. Ditch check soxx may be stacked on top of each other if additional height is required.
  4. Stakes shall be used to stabilise the ends of the ditch check soxx.
  5. Stakes should be 50mm x 50mm x 600mm softwood and should be located as follows
    • sand and loam soils = 300mm deep
    • clay soils = 200mm deep
  6. Vegetated drain checks may be seeded at the time of manufacture and installation to create a contained ‘living’ bio-filter and left intact after completion of the construction period.

Inspection and Maintenance

  1. Routine inspection should be conducted within 24 hours of a runoff event or as designated by the regulatory authority.
  2. Check dams should be regularly inspected to make sure that they maintain their shape and that they are producing adequate hydraulic flow through.
  3. If ponding becomes excessive, additional ditch checks or sediment removal may be required.
