The Clearwater NSBP006 Bypass Separator is for areas up to 3,335 sq/m. This range of Bypass separators from Clearwater, provide the ideal solution for low risk floods – when there is little possibility of a combined heavy rainfall and large spillage.
Bypass separators are used when it is considered an acceptable risk not to provide full treatment, for very high flows, and are used, for example, where the risk of a large spillage and heavy rainfall occurring at the same time is small, e.g. Surface car parks, roadways, lightly contaminated commercial areas.

Clearwater Plastic Bypass Separators Guidelines
Each bypass separator design includes the necessary volume requirements for:
- Oil separation capacity
- Oil storage volume
- Silt storage capacity
- Coalescer
Bypass Separator Alarm Options
Environment Agency PPG3 Guidelines stipulate that all separators must be fitted with a robust system to provide an audible and visual alarm if the oil level becomes too high. We strongly recommend that you purchase the Darcy Mains Alarm alongside this item, and it will be delivered with the separator ready to wire in.

Features and Benefits of the Clearwater NSBP006 Bypass Separator
- Light and easy to install
- Inclusive of silt storage volume
- Fitted inlet/outlet connectors
- Extension access shafts for deep inverts
- Maintenance from ground level
- GRP or rotomoulded construction (rotomoulded for NSBP003, NSBP004 and NSBP006)
To specify a nominal size bypass separator, the following information is needed:
- The calculated flow rate for the drainage area served. Our designs are based on the assumption that any interconnecting pipework fitted elsewhere on site does not impede flow into or out of the separator and that the flow is not pumped.
- The drain invert inlet depth
- Pipework type, size and orientation.
