Our drain pollution guards (or drain wardens) are a unique and cost-effective solution to prevent drains from congestion while protecting our waterways. The pollution guard fits easily under the drain and captures rubbish, debris and coarse sediments. A low resistance to water flow ensures effective drainage while the included bilge boom removes hydrocarbons, oils and fuels. Designed for use on construction sites, civil work sites, delivery docks, retail centres and parking lots. Available in two standard sizes, sides can be trimmed when in place to custom fit the space you require.
