Water Quality Objectives

The marine treatment of sewage has become a well established practice in the UK. The technique involves the discharge of sewage through a system of ports or diffusers at a carefully chosen location (often several, kilometers out to sea) which will ensure that the subsequent dilution and dispersion of the sewage will achieve the required water quality objectives. The paper describes the studies and investigations that are carried out to determine the most appropriate discharge location and discusses the design of the pipeline and diffuser systems. The various construction techniques used in the UK to date are described, as well as the pre-treatment equipment and the methods of monitoring outfall performance. Particular attention is drawn to the need to undertake marine biological base-line surveys prior to commissioning as well as regular surveys after commissioning, both to ensure the environmental objectives are being met and to monitor the effects of the discharge.
