Solid transport in combined sewerage systems
type: CreativeWork
description: Interest in the problems caused by the deposition of sediments in sewers, and by the transport of solids through and from sewer systems has given rise to a great deal of research both in the UK and internationally. A collaborative research effort has been initiated by the Water Research Centre (WRc) under the auspices of the UK Urban Pollution Management (UPM) programme to study all aspects of sediments in sewers. The work of the Wastewater Technology Centre (WWTC) of the University of Abertay Dundee (UAD) has made a major contribution to this aspect of the UPM programme. The work reported in this thesis constitutes a significant component of the WWTC research on solids transport in sewers. The accurate prediction of solids transport in sewers is a problem which has been addressed by a number of workers using various approaches, none of which has currently proved wholly satisfactory. This thesis describes an investigation of the transport of solids in combined sewers during both dry weather flow periods and storm flows. The study is based primarily on measurements of flow conditions and suspended solids concentrations at two sites on the main interceptor sewer at Murraygate, Dundee City Centre and one other site on a trunk sewer in the Perth Road area of Dundee. In addition, information on the associated accumulation of sediment in sewer inverts was obtained. The relationship between hydraulic conditions in these combined sewers and the transport of solids in suspension has been examined. The aim of the work was to arrive at a methodology by which an appropriate model could be selected or developed which would predict solids transport rates given information on hydraulic conditions.
