<p>what is the basic difference between simplified sewer system and conventional sewer system.</p>
Simplified sewerage, also called small-bore sewerage, is a sewer system that collects all household wastewater (WC wastes and sullage) in small-diameter pipes laid at fairly flat gradients. Simplified sewers are laid in the front yard or under the pavement (sidewalk) or - if feasible - inside the back yard, rather than in the center of the road as with conventional sewerage.
It is suitable for existing unplanned low-income areas, as well as new housing estates with a regular layout. With simplified sewerage it is crucial to have management arrangements in place to remove blockages, which are more frequent than with conventional sewers. It has been estimated that simplified sewerage reduces investment costs by up to 50% compared to conventional sewerage.
Simplified sewerage is sometimes also referred to as conventional sewerage with appropriate standards, implying that most conventional sewers are overdesigned.
