Abstract

As a result of a combination of the European Communities (EC) BathingWater and Urban Waste Water Treatment Directives, the option of discharging biologically treated effluent into estuaries and shallow coasteal waters through short outfalls is being increasingly considered. This has meant that sewage disposal models are now required to resolve water movements in inshore waters. As part of an environmental assessment into the options for the treatment and disposal of sewage from Felixstowe, Harwich and Dovercourt, Anglian Water commissioned WRc to produce a bacterial dispersion model of the area, It was necessary to quantify the complex flows suspected in Harwich Harbour and to be able to simulate their impact on effluent dispersion, This paper describes the development and application of this model. A detailed 2D hydrodynamic model was calibrated against Vessel Mounted Acoustic Doppler Current Profiler data gathered in the area. A bacterial dispersion model drivenby this hydrodynamic model was validated using bacteriophage tracer releases. The model has been applied to demonstrate that the treatment options under consideration will comply fully with the Bathing Water Directive and are constant with the Anglian Water Environmental Policy.
