SPEL Monitoring & Containment Systems

Monitoring and control of outfalls is an area SPEL Products have advanced systems to safeguard outfalls in sensitive sites eg sites of special scientific interest – SSSI sites and/or where specific outfall discharge consent levels have to be maintained 24/7.

Product Sizing

All tanks and chambers are available from 200-600 Series.
Site specific requirements and design detail will be confirmed with the client and SPEL’s Special Products team.


  • Fire water containment
  • Airport de-icing
  • Non-fuel tanker delivery areas
  • Food processing / Washdown areas
  • Chemical spill zones

Shell Design

Designed with reference to BS EN 13121. All tank shells carry the SPEL 25 Year Warranty and life expectancy in excess of 50 years.

Shell Specifications

Different tank shell specifications are available dependent upon tank invert levels, ground conditions and ground water levels. (See Installation Guidance section)

Inlet/Outlet Connections

Pipe connections available to accommodate most standard sizes.

The Monitoring Chamber is the heart of this system and provides not only monitoring but also the ability to automatically divert the flow or close the network, depending on the design. This chamber is available in sizes from 1.2m diameter to the largest 4m depending on incoming pipe size and number of monitoring probes.
The Containment Tank can be horizontal or vertical, single or double skinned depending on site constraints, and is located off line so that diverted flow can be safely contained and tankered off site for safe treatment.
The key benefit of this system, other than its pollution capture capacity is that it can be simply reset by the client/ operative and NOT bring the site to a stop or risk flooding.

Typical Layout – SPEL Pollution Monitoring and Containment System

The above diagram shows a bespoke system designed for Jaguar Land Rover, Wolverhampton. This diagram accompanied by the description below shows SPEL’s extensive capabilities to design a bespoke system to suit site requirements and pollutants.
Complete protection of the drainage system is provided 24/7 by the SPEL Automatic Pollution Monitoring and Containment system and, in addition, the SPEL Puraceptor® separator incorporates an automatic closure device (ACD) in the case of a heavy spill. This double protection provides a ‘belt and braces’ safeguard for complete confidence. The above system also incorporates a SPEL Puraceptor. This adds additional oil capturing and includes an ACD to give complete peace of mind.

Spillages and leaks that can occur in the handling and storage of hydrocarbons and chemicals are always a danger to our environment, therefore, as with such high profile developments as the new engine plant at Jaguar Land Rover any potential risks must be carefully considered at design stage.
SPEL Pollution Monitoring, Diverting and Containment Systems typically comprise of a diverter chamber followed by a SPEL Puraceptor® (two chamber model) full retention Class 1 fuel/oil Separator to remove hydrocarbons as a result of minor spillages washed down during normal rainfall events.

Following the SPEL Puraceptor® is the monitoring and valve chamber. The monitoring system incorporated is designed to detect the pollutants posing a risk. The level of concentration of these pollutants can be set to within the sites allowable discharge limits and when exceeded, automatically close off the drainage route and divert the contaminants to a containment tank.
If such a spillage occurs and fills the containment tank the pollutants require sucking out and dealing with by a specialist waste company.
Unless a spillage occurs the discharge from the SPEL Puraceptor® continues to the drainage system and off site.
