Filter soxx used for runoff diversion
Generally used upslope of areas undergoing excavation
Effective at diverting sheet flow runoff coming from stabilised areas flowing to unstable or bare soils
Direct runoff flows to stabilised channels, vegetated areas, collection ponds or stormwater inlets
Also used for temporary diversions on paved surfaces to protect adjacent disturbed soils
Can be direct seeded to allow vegetation establishment to provide permanent control of runoff velocity.
Runoff Diversion Soxx Installation
Runoff diversion shall be installed above and adjacent to areas of unprotected soil or areas prone to soil erosion.
Runoff diversion placed on slopes greater than 5 % may require erosion control and soil stabilisation measures where runoff flow is concentrated.
Runoff diversion shall not be used on slopes greater than 2:1.
Stakes should be installed on the low side of the soxx at 3 metre intervals.
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
If the sediment control soxx are to be left as a permanent filter or part of the natural landscape, the soxx may be seeded at the time of installation for the establishment of permanent vegetation.
Inspection and Maintenance
Routine inspection should be conducted within 24 hours of a runoff event or as designated by the regulatory authority.
Runoff diversion soxx should be regularly inspected to make sure that they maintain their shape and that they are adequately diverting stormwater runoff.
If ponding becomes excessive, additional runoff diversion may be required, or the soxx may need to be adjusted to allow gravitational flow of water down slope.
Filtrexx® filter soxx used for runoff diversion should be used in conjunction with geotextile matting and compost blankets.
