Sewer blockages are the single greatest operational expense for sewer system operators. Spills from blocked sewers are now the cause of the majority of sewerage flooding of property incidents and environmental pollution events. They are also the largest cause of customer complaints relating to wastewater services.
Six wastewater utilities are working with WRc to help reduce sewer blockages by bringing blockage clearance practice up to the highest standards currently used in the UK. These improvements should eliminate the need to revisit a blockage site because it was not cleared properly the first time. This getting it right first time approach also has the potential to reduce the overall cost of blockage clearance.
Sewer blockage clearance practice varies depending upon a number of factors such as; location; accessibility of the sewer; likelihood of property flooding and size/depth of sewer. Best practice varies depending upon these circumstances and the most appropriate equipment used in the clearance. The collaborative Portfolio project “Sewer Blockage Clearance – Best Practice Guidance” (CP468) will capture best practice for a range of situations and will assess what practices to use, when and where.
Outputs from this practical based project will a “Best Practice Guidance Manual”, quick reference guides for site crews and a training video.
