Luton Airport opened in 1938 for use by the Royal Air Force during the Second World War. Commercial and general flights resumed during 1952 and since then has grown massively in the packaged holiday market. Thanks to 100’s of millions of pounds worth of investments since the 1990’s, London Luton Airport has grown to become the fifth busiest airport in the UK with sustained growth ahead.
Since 2022 large scale developments at London Luton Airport have increased in number, with SPEL privileged to be involved on many of these projects with main contractor Ryebridge Construction. SPEL have provided products from right across our large range of tank based solutions. From SPEL Puraceptor full retention separators, through SPEL Stormpump stormwater attenuation and pumping system, SPEL Penstock/Valve Chambers and right through to SPEL ESR Range stormwater treatment devices. Whatever was required, however bespoke the needs where, SPEL were able to deliver.
High quality solutions have always been the requirement from London Luton Airport and the contractor, Ryebridge. SPEL manufactured 2no. SPEL Puraceptor full retention separators (models P400/1CSC and P200/1CSC) for Luton Airport in 2022 and 2023 which were chosen because of their Automatic Closure Device, which will shut off the system in a catastrophic oil spill event. More recently in 2024 we manufactured our market leading SuDS treatment device, our ESR Bypass treatment system (model 350C1/ESR) for their new temporary drop-off zone.
As part of a large terminal and taxiway upgrade, over 700,000 litres of stormwater attenuation was required. The outfall for the attenuation tank was 15 metres from the proposed location and uphill of the attenuation tank base. SPEL designed and manufactured 8no. interconnected SPEL Tankstor tanks, each with 90,400 litre capacity and from our 400 Series range (2.6m diameter). One of these 90,400 litre tanks was manufactured with a sump for a dual pump, Duty/Standby pumping system to be installed. SPEL designed and provided the full pumping system, including quality Grundfos pumps to pump at 3 l/s with 0.9m head and a 15m rising main length and the automatic control panel and accompanying level monitoring equipment and internal pipework, pump pedestals and guiderails. This attenuation system is a cost effective, long term solution, with easy access to all parts of the tank for ongoing maintenance, and the pumping system installed within the tank, removing the need of a separate pumping station.
Glycol is the chemical that is used for de-icing aircraft. Unlike an oil, it does not have a specific gravity which can be captured within a traditional stormwater treatment device (such as an oil separator) and therefore must be captured. SPEL designed and manufactured 4 no. Penstock/valve chambers ranging from 1.8m to 2.6m internal diameter. They were factory fitted and tested in our manufacturing facility with 600mm or 800mm stainless steel/HDPE penstocks, automatically closed by an actuator valve. Prior to starting any de-icing, a button is pressed in the control room, which closes all of the penstock valve. This captures all of the Glycol fluid within the drainage network. Once the de-icing is complete, London Luton Airport fluid tankers connect up to a Bauer coupling within a SPEL designed and fitted out GRP lockable kiosk. A single Grundfos Pump with associated pedestal and guiderail system was fitted within the SPEL Penstock/Valve Chambers. This pump could be activated by the tanker driver, pumping the glycol solution out of the drainage system and into the tanker.
