Filter Soxx used for ditch checks
- Provide a porous physical barrier perpendicular to concentrated stormwater flow
- Are designed to reduce and disperse runoff energy
- Reduce erosion by slowing runoff velocity and dissipate concentrated stormwater runoff flow
- 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
- 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.
- The centre of the ditch check should be at least 150mm lower than the sides of the channel.
- Ditch check soxx may be stacked on top of each other if additional height is required.
- Stakes shall be used to stabilise the ends of the ditch check soxx.
- 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
- 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
- Routine inspection should be conducted within 24 hours of a runoff event or as designated by the regulatory authority.
- Check dams should be regularly inspected to make sure that they maintain their shape and that they are producing adequate hydraulic flow through.
- If ponding becomes excessive, additional ditch checks or sediment removal may be required.
Ditch Check Soxx Applications
- Mining and coal seam gas sites.
- Road and rail infrastructure.
- Urban and rural subdivisions.
- Golf courses.
- All erosion control and stormwater management projects.
