HydroSystem 1500 – Stormwater Treatment Device
A Hard SUDS stormwater treatment device to treat polluted runoff from roads, car parks, metal roofs, industrial sites and artificial sports pitches.
Connectable surface area from 1600 to 3600m2 depending on the contamination level of the runoff. For installation in either concrete or plastic chambers within 1500mm shafts. Fully DIBt approved, and so meets UK EA approval. This is the Big Brother of the well known and DiBT approved HydroSystem 1000 series.
The HydroSystem 1500 treatment device combines a hydrodynamic particle separator with a filter unit above it. This two step, multi process treatment train within the one SUDS Treatment Device removes both the solids and dissolved substances from stormwater. Space saving design, below ground, provides certainty of performance. Vastly exceeds the removal performance of oil grit separators. Retains litter and inflatables. Filters our microplastics at 100% to 70 microns.
The cleaned water can be discharged directly into infiltration systems, to SUDS surface waters or other green infrastructure components.

Stormwater SUDS Treatment Device – How it works
- The stormwater runoff is directed into the lower treatment room of the system. The angled inlet generates a radial vortex flow pattern.
- The hydrodynamic particle separator promotes particle sedimentation, particularly of the sand and silt fraction.
- The sediment is retained in a silt trap chamber below the separator. DiBT approved and tested. The silt trap is emptied out at site specific intervals.
- The water then has to pass an upflow filter device built of six cartridges. In the filter element filtration adsorption and precipitation takes place. The filter cartridges can be back-washed.
- The filter elements can be easily exchanged through the shaft opening.
- The treated water passes via an oil baffle and discharged the system by the outlet.
The HydroSystem multi process devices fully pass the DiBT standard, as referenced in the CIRIA SuDS manual (see Ch 14 Part D: Technical Detail, and Ch 26, Part E: Supporting Guidance). In so doing, they provide a certainty of performance standard that is understood and accepted by the Environment Agency (EA) in England.
