Ultra Drain Guard

Ultra Drain Guards (also known as Witches Hat Drain Guards) are specifically designed to filter out oil and sediment from surface water flowing into gully drains, making them ideal for use around construction sites, farms, industrial estates, and other areas susceptible to stormwater contamination or runoff from cleaning activities.

Ultra Drain Guards are constructed from a high-permeability, non-woven polypropylene geotextile that effectively captures solids and oils while still allowing water to flow through. They also feature built-in bypass ports to help maintain consistent drainage.

Designed for easy installation directly into drain gully pots, these guards filter out contaminants as they enter the drain without hindering water flow. The Oil and Sediment model can absorb up to 3.29 litres of hydrocarbons and hold up to 18kg of sediment, sand, or debris.
