SG1 Silt Guardian Data Sheet

Full Description

Through similar functions of the bypass separator design, the silt separator intercepts silts and sediments upstream of storm attenuation systems. Functioning as a filtration system, the SG4 temporarily stores water, allowing unwanted particles to settle on the bottom of the unit. This prevents any siltd from entering into water storage systems.

Specifically, in residential areas, these systems contribute to effective stormwater management as it prevents blockages and improves flow rate of drainage systems. Also suitable for domestic or commercial developments, the SG4 is equally applicable in vehicle washdown areas.

Key Benefits:

- Improved water quality
- Protection of stormwater systems
- Prevention of environmental contamination
- Enhanced flow rates
- Versatility

In summary , the installation of a silt separator provides a range of environmental, regulatory, and practical benefits for many varied industries. This product contributes to sustainable and responsible water and land management practices.


Waste that develops from vehicle washing and cleaning businesses, may be referred to as ‘ contaminated waste’. In that instant, there is a duty of care to responsibly dispose/ recycle through a professional and registered waste carrier. This waste should be disposed in a suitably licensed facility.
