Our large fleet of tankers collect liquid digested sludge from treatment works and transport to locally sourced registered field sites for recycling. This digested sludge is then applied to the land via Injection or Surface application. Most frequently the preferred method is injection through an umbilical system and utilising a nurse tank, which maximises the nutrient benefit to the land owner and can reduce the risk of odour release. Prior to any operations, Wrights will ensure all permits and Risk Assessments are complete and approved.
