Beckton STW is the largest sewage treatment works in Europe. The site is around 250 acres and treats the waste from more than 3.5 million people. Being located close to London, the treatment works has had to grow rapidly to keep up with the rising population increase. The treatment works has been at this site since the 1860’s! The new ‘Super Sewer’ that has opened as part of the Thames Tideway project, will divert a certain amount of the combined sewer overflow (CSO) that it captures to Beckton STW for treatment, ensuring that CSO pollution spillages are reduced in the River Thames.
A fuel spillage blind tank was required and the consulting engineers, Mott MacDonald specified a SPEL Tankstor 300 series with 8,000 litres capacity to capture any fuel in the case of a spillage.
A chemically resistant (SPEL CR) internal liner was chosen to ensure that the potentially corrosive substances entering the tank would not degrade the tank shell. On many sewage treatment sites, SPEL supply chemical blind tanks in our SPEL HCR (Highly Chemical Resistant) internal liner as these sites often have large deliveries of environmentally harmful chemicals which are used in the treatment process. If there is a spillage during a road tanker offloading these chemicals, they must be captured and this is what SPEL Tankstor’s are often used for on waste water and water treatment works for most of the water companies across the UK.
Due to SPEL’s bespoke manufacturing capabilities, this tank was supplied with 6” sludge removal pipework with a stub flange and backing ring for connection to a Bauer Coupling for easy sludge/spillage removal by a vacuum tanker. 2no. 6” Instrumentation access points, a 6” ventilation pipework and a 750 diameter access opening with a GRP lid which comes with lifting handles were supplied to meet the Thames Water/Mott MacDonald specification.
