The silt warden is used to trap silt and course sediments before they continue into stormwater drains. This simple and cost effective device assists in achieving environmental compliance on worksites.
The silt warden is specially designed to protect stormwater systems during the construction of infrastructure projects, in particular road ways. It can prevent blockages within the stormwater system. This solution is especially effective when installed in the early stages of construction and landscaping activities.
How the silt warden works
Our silt wardens are manufactured from high tensile, UV stabilised HDPE shade cloth. It has a skirt and a basin. Once installed under the drain grate, it will function as a filter for the runoff heading into the pit. The basin has a capacity of 0.117 cubic metres.

- 1.3mL x 1.3mW x 50mmD skirt
- 600mmL x 600mmW x 600mmD tapered basin
The silt warden is easy to install. It is sized to fit a standard drain pit. You simply lift the grate, fit the silt warden in the pit and use the grate to hold it in place. Reinforcement can be achieved using zip ties to attach the handles to the grate.
Once installed the device and the pit should be inspected both on a regular basis and after rain events. Once the silt warden has reached capacity it can be removed using heavy equipment such as a forklift. It should then be responsibly disposed of according to local regulations.
