The SPEL ESR Bypass is fully certified to meet the CIRIA SuDS Mitigation Index. It has been tested by WRc to the British Water Code of Practice for Manufactured Treatment Devices. This unit is also certified to the British and European Standard BS EN 858.
SPEL’s ESR range is a total treatment system removing Hydrocarbons, Total Suspended Solids (TSS) and Metals. It’s a highly efficient, single unit, water quality SuDS component.
The coalescer inserts are easy to clean and simple to replace but rarely require replacing. The unique ‘insert’ format ensures that this unit can be extracted complete every time, compared to other systems where ‘wrap around’ style units allow the foam to slip off, requiring confined space entry to retrieve.

The ESR Bypass will treat up to the 1 in 1 year storm event for surface water run-off to a Pollution Hazard Index of ‘Medium’. This covers surfaces such as:
The ESR Bypass can be used as part of a treatment train to achieve a ‘High’ Mitigation Index. (See other SPEL SuDS treatment systems).
Designed with reference to BS EN 13121. All tank shells carry the SPEL 25 Year Warranty and life expectancy in excess of 50 years.
Different tank shell specifications are available dependent upon tank invert levels, ground conditions and ground water levels. (See Section 8)

The ‘standard’ specification is normally adequate for most installations but Heavy, Extra Heavy, Special, Extra Special, Ultra and Ultra Plus specifications are available depending upon the burial depth and water table level, in winter. The concern is when the system is emptied completely and remains empty for a period of time.
For more information and to see burial depth charts see Installation Guidance.

*These connectible/catchment areas are based on the SuDS Manual requirement for bypass devices to treat the 1 in 1 year storm event (27mm).
**SPEL ESR Bypass Treatment Systems are designed for a maximum flow (NS/NSB) but can be fitted with larger than the recommended maximum connection size IN/OUT or with the addition of adapters providing the maximum flow (NS/NSB) cannot be exceeded or any increase in the operating level in the SPEL Separator to cause the captured pollutants to escape into the vent connections or through access shaft connections. Any overriding of the above criteria could jeopardise performance to the European Standard BS EN 858-1.
To facilitate easy insertion of coalescer units, the optional SPEL guide rail system manufactured in stainless steel can be incorporated into SPEL ESR Bypass Systems.
Brackets fixed to the top and bottom of the coalescer unit simply engage with the stainless steel guide rail which is fixed to the top of the stub access shaft. The coalescer unit is then lowered in the normal way, being guided at the correct angle into the conical base.
Lifting chains are available for the larger coalescer units and where extension shafts are fitted.
Extension guide rails can be incorporated into SPEL extension shafts to suit.
Where SPEL ESR Systems can be subjected to surcharging and/or tidal outfall, then the SPEL 3L system should be included.
The SPEL Lifting, Locating and Locking system is manufactured in stainless steel and replaces the standard coalescer unit handle.
The locating/locking handle ensures the coalescer unit is seated and locked in its correct position.

Dependent upon model and diameter of connections, these nine different orientations are available. However, on the larger models it is important to check with our technical department.
Extension access shafts are available for deep invert application and are available in 500mm height increments.
Where surface water run-off has a high silt content the coalescer units can become filled, making them heavy to lift out. In order to facilitate easy withdrawal of coalescer units the SPEL tripod and hoist is recommended.
