Our bypass separators are engineered to treat light surface water runoff by removing oil, hydrocarbons, and suspended solids before discharge.
They’re ideal for low-risk catchment areas such as car parks, access roads, and forecourts, where full treatment capacity isn’t required under normal rainfall conditions.

During heavy storms, excess flow bypasses the separator chamber to prevent overflow while still ensuring effective pollutant removal in everyday conditions.

Fully compliant with EN 858-1 and UK environmental standards, our bypass separators deliver dependable performance and simple installation for a wide range of commercial and industrial applications.
