DP World London Gateway, a smart logistics hub near London, has selected WPL’s technology to deliver enhanced ammonia removal in order to protect sensitive waters within the Thames Estuary.
WPL, a water recycling specialist company within WCS Group, will be providing a custom wastewater treatment plant for a new detached warehouse for 150 office workers, currently under construction in the logistics hub. The plant will be able to process 1981 gallons daily for a population equivalent of 100. The hub is located on the north bank of the River Thames in Thurrock, Essex, 25 miles from central London.
The package plant will discharge into an environmentally sensitive swale, which feeds into the Thames Estuary, and must meet stringent Environment Agency standards of 15:15:03mg/l for ammonia and suspended solids.
WPL will provide one below-ground high performance aerated filter (HiPAF) system to deliver ammonia removal, with one dosing unit and sand filter to further improve final effluent in line with the site-specific consent requirements. The design also includes a small pumping system due to the depth of the incoming drain and a pumped flow return chamber.
Dominic Hamblin, technical manager for WPL, said, “DP London Gateway is a major logistics hub, and we are excited to be delivering this onsite environmental solution on its behalf.”
“WPL’s modular HiPAF range meets stringent European environmental discharge consent standards, without the use of chemicals,” Hamblin continued. “The technology is regularly specified by UK water utilities and is an effective choice for sensitive locations such as swales, which are shallow and not heavily diluted.
WPL’s treatment plant will be constructed by Readie Construction. Construction is due to start before the end of 2021 and is expected to take 12 weeks.
