Shirebrook Project Summary
Shirebrook STW is located approximately 5 miles north of Mansfield town center and caters for a population equivalent (PE) of 12,000. As part of the AMP6 Chemical Investigations Programme, Severn Trent Water was required to carry out a full scale trial of a ‘proprietary’ iron dosed sand filter plant on a works serving between 10,000 and 50,000 PE. The trial is to assess the effectiveness of the process at removing priority hazardous substances/ hazardous substances/specific pollutants (PHS/HS/SPs) as defined under the Water Framework Directive (WFD) – in this case cadmium. In addition, WFD modelling has identified there is a high probability that Shirebrook STW will be subject to a phosphorus consent of approximately 0.2mg/l. Severn Trent Water promoted a scheme to address this and the requirements of the trail in March 2015 and appointed their framework design and build contractor, NMCNomenca, to carry out the work.
