resource: Technical solutions envisaged in managing solids in combined sewer networks
  type: AcademicArticle
  abstract: Solids in combined sewer networks represent two important technical questions: -the clogging of man-entry sewers, and -pollution in urban wet weather discharges, whose main vectors are generally suspended solids. 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 largest solids; selective trapping of bed load solids, which form deposits; and the displacement of deposits using dry weather flow flushing waves. We shall then examine technical solutions to control pollution in urban wet weather discharges. This will show that decantation is an efficient means of fighting pollution. However, it is not always feasible because it involves large scale investments. Complementary methods should, therefore, be developed and used at different points in the water’s passage through an urban drainage area. Copyright (C) 1996 IAWQ.
