This velocity is dependent on the pipe diameter, the type of sediment, and the roughness of the pipe walls.<\/p>\n<p>For clean, smooth pipes, the self-cleansing velocity is typically around 2 metres\/sec. However, for pipes with rough walls or carrying sediment-laden water, the self-cleansing velocity may be significantly higher.<\/p>\n<p>It is important to maintain a velocity above the self-cleansing velocity in order to prevent the build-up of sediment in pipes.
