WRc Sewer Cleaning Manual

The WRc Sewer Cleaning Manual is a UK industry reference giving guidance on sewer cleaning techniques and equipment, including high-pressure jetting, rodding, winching and silt removal. Published by the Water Research Centre, the document supports water and sewerage undertakers, framework contractors and private drainage businesses operating across Greater London. While the manual is not statutory, it sets out widely accepted methods that inform contractor competence, equipment selection and risk management. Practical implications for homeowners commissioning drain cleaning include expecting their contractor to operate jetting pressures and equipment in line with the manual, which protects pipework while removing blockages effectively. The manual is regularly referenced alongside the WRc Sewerage Manual and the WRc Manual of Sewer Condition Classification, providing a complete suite of UK industry guidance from survey through to rehabilitation and ongoing maintenance.
