Worksop Sludge Treatment Facility (STF) has been constructed to cater for a lack of sludge treatment capacity
within Severn Trent Water’s (STW) Northern Area. The Worksop STW site was selected as central to the area
and a new access road was constructed as part of the scheme to better connect the facility to the surrounding
road network. The STF is designed to process a peak load of 10,209 tonnes dry solids (TDS) a year of sewage sludge
with approximately 80% of this coming from tankered imports. The plant was designed around acid phase digestion
(APD) to maximise gas yield and solids destruction.
