Attenuation & Flow Control

Reducing flooding and controlling stormwater is central to all good SuDS design and SPEL’s comprehensive range helps to deliver the correct storage and control.

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.

SPEL Tankstor tanks offer a cost effective solution for stormwater attenuation especially in areas where cratebased systems are challenged due to high ground water and/or high lateral loads.
The comprehensive range from 1000 – 300,000 litres, across 5 different diameters, offers a great starting point.
Tanks can be interconnected to increase the total storage capacity by use of multipe pipe size options making for simple installation. This type of attenuation format is particularly useful where the attenuation must keep within the footprint of the building and/or include a rainwater harvesting system.

For full range of tank sizes, including diameter and length options, see Section 4. SPEL’s bespoke manufacturing capacity provides engineers and contractors with the flexibility to design attenuation systems to suit all applications, this not only includes the tank size but also multiple pipe size and location options as well as a range of access points.
The inclusion of pumps is also an option (see SPEL StormPump on page 35), these can act as the flow control device. More specialised pumps can also be installed to send the flow to the SPEL RainSave rainwater harvesting system.

13no, 240,000L SPEL Tankstor Tanks, providing just over 3.1m litres of storage at Gatwick Airport

Due to the complexity and demands of modern developments the requirements for pumping stormwater are increasing.
SPEL StormPump delivers the perfect combination of attenuation volume and pumping capabilities all in a single ‘off-site built’, packaged system.
The SPEL team are available to help outline the optimum combination of tanks, pumps and pipework to ensure the combined system delivers efficiency and at peak performance.
Key benefits of SPEL StormPump are the accurate control of discharge flow rates, the ability to reduce attenuation size, and eliminating issues around pipework falls and levels across the drainage network.

SPEL StormPump utilises the full range of tank sizes, including diameter and length options see Section 4 for the complete range. SPEL’s bespoke manufacturing capacity provides engineers and contractors with the flexibility to design and deliver this system to suit all applications, including the use of horizontal and vertical chambers.

SPEL Flow Control Chambers are manufactured in filament wound GRP as a single piece chamber providing a lightweight but strong unit with excellent flow characteristics. These can be fitted with either a vortex control unit or an orifice plate to meet engineer specification and flow rates. These units are fully ‘offsite built’ being delivered to site as a ‘plug and play’ system. The lightweight construction allows for simple offload and accurate placing of the unit on site thus reducing installation time and associated costs. Further benefits include no confined space entry and a bespoke design which further helps to streamline the installation and reduce costs. Reduced site work together with health and safety benefits make the SPEL StormCheck a preferred option over concrete. The pre-fabricated chamber comes complete with either the specified vortex flow controller or orifice plate and the option for multiple inlet pipe connections.

The larger SPEL StormCheck chambers can also accommodate extra storage capacity where site constraints limit the size
of the attenuation tank. For example, a 500 Series chamber at 2.5m dept has a gross capacity of 22,000L.

  • Lightweight for easy offload and placement
  • No confined space requirements

SPEL StormCheck VFC325 Vortex Flow Control Chamber, Ford Motors, Essex.

For some stormwater attenuation systems, a SPEL StormBrake tank can offer savings in reducing the required attenuation volume. This is done by ensuring the flow control device is working at maximum performance for the longest possible duration.
The tank is a two compartment unit comprising of an inlet chamber, where the incoming water level rises quickly to the required head for the flow control device to operate at its optimum performance, this happens early in the storm event, allowing a higher flow for longer when compared with a shallow attenuation tank. A high level weir allows excess stormwater to pass over into the attenuation storage capacity in the second compartment and interconnecting tanks (if fitted).
As the storm abates and the level falls in the inlet chamber, non-return valves in the base of the weir wall open to allow stormwater to pass back into the inlet chamber and out through the vortex flow control device.

*Overall length subject to inlet/outlet and orientation.

**SPEL Separators 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.

Note: Model FP1C/SC is a special Forecourt separator with 7600 litre spillage holding capacity. Click here for more information on Forecourt Separators.

*Overall length subject to inlet/outlet and orientation.

**SPEL Separators 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.

Note: Model FP2C/SC is a special Forecourt separator with 7600 litre spillage holding capacity. Click here for more information on Forecourt Separators.
