In this paper, we shall present first, curative technical solutions which avoid or remove deposits in man-entry sewers. We shall discuss the partial extraction of the. High strength wastewater can cause sewer problems such as sewer Ashley, RM ( ), Solids in sewers: characteristics, effects and control of sewer solids. Studies undertaken in Belgium, France, Germany and Scotland have shown that the deposit situated at the water-sediment interface (termed the Near Bed.This Report presents information on the current state of knowledge of the origins, occurrence, nature and effects of sewer solids for use by engineers, scientists, administrators and water quality planners for the planning, design and operation of sewerage systems. A gravity sewer is a conduit utilizing the energy resulting from a difference in elevation to remove unwanted water. The term sewer implies removal of sewage or surface runoff rather than water intended for use;  and the term gravity excludes water movement induced through force mains or vacuum sewers. duces solids’ transfer in sewers. When considering reducing water usage through water conservation, these savings could be cancelled out by an in-creased population and the situation exacerbated by the impacts of climate change. There are issues in relation to varying design methods a reliance on, engineering judgement in sewer design, uncertainty relating to future water stress, and a lack of cross .
