Filter Soxx used for concrete washouts
- Concrete wash-off and washout from equipment and trucks.
- Where surface water is pumped to allow access to stream banks for stabilisation projects.
- Sediment and stormwater pond emergency overflow capture and filtration.
- Dredging slurry filtration.
- Non-hazardous industrial effluent and slurry solids separation from point sources.
Concrete Washout Soxx Installation
- Installation of concrete washouts shall ensure that the containment area is sufficient to handle the rate and volume of influent flow.
- When installed on non-paved surfaces, stakes should be installed on the inside of the concrete washout at 1.5 metre centres.
- 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
- Concrete washouts may be installed on top of impermeable mats or geotextiles to prevent percolation of contaminated water into soil.
- Concrete washouts shall not be placed near concentrated or high sheet flows of stormwater runoff which may compromise the structural base of the concrete washout.
- Concrete washouts may be seeded at time of installation to create a vegetated living bio-filter.
- Concrete washouts installed on paved surfaces should be stabilised along the outer circumference using concrete blocks for structural support.
Inspection and Maintenance
- Routine inspection should be conducted within 24 hours of a runoff event or as designated by the regulatory authority.
- Concrete washout soxx should be regularly inspected to make sure that they maintain their shape and that they are producing adequate hydraulic flow through and solid removal.
- If rainfall is excessive, additional concrete washouts may be required to contain the added water volume.
Concrete Washout 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.
