KIRK UK, part of KIRK GROUP, has recently completed upgrades to the Wanlip Sewerage Treatment Works based in Leicester.
KIRK UK, part of KIRK GROUP, successfully constructed the UK’s largest Anaerobic Digestion Plant in Staffordshire, West Midlands.
Wanlip STW is one of Severn Trent’s major sewerage treatment facilities and treats domestic and industrial waste from inhabitants and factories in Leicester and nearby villages. The site runs over 40 hectares and serves a population of approx. 500,000.
The original plant was built way back in 1964 as an integrated sewerage and household waste treatment facility. By 1987 more capacity was needed and the ‘New Works’ were added the plant. Two CHP engines were built on site to convert the excess gas produced in the digesters into renewable energy used to power the plant and the excess sold to the National Grid.
In 2013 Severn Trent were again faced with the need to increase capacity on site due to a prediction in growth in the area and to meet with the Ofwat requirements. Also the existing equipment was reaching the end of its expected operational life and therefore needed updating with the latest products in the market to keep up with the plant requirements.
KIRK were selected by the E5 Joint Venture to design, supply and install six epoxy coated steel digesters all complete with stainless steel roofs, providing a total of 24,000m3 capacity on site. Access to the centre of each roof would be granted via a 900mm wide walkway leading to a 4m diameter central access platform. A handrail was also constructed around the full perimeter of each roof.
Epoxy coated steel is a long-lasting coating in- novation with maximum corrosion and weather resistance, perfect solution for the wastewater market.
