Sewerage Proposal for Clan Jetty, Penang

Abstract

Sewage systems transport sewage through cities and other inhabited areas to sewage treatment plants to protect public health and prevent disease. Sewage is treated to control water pollution before being discharged to surface waters. Sewerage systems are very important for housing areas as they ensure that human waste is disposed of properly and directed to the treatment plant. At Clan Jetty, Penang there is no sewerage system, so human waste is directly disposed of into the water. As a place of historical interest which encourages visitors to come, seeing the human waste floating on the water surface and smelling the dirty water is not good for tourism. The function of a sewerage system is to transfer any wastes such as those that are ordinarily discharged from toilets, water closets, baths, showers, sinks, basins and other sanitary and kitchen fitments. The absence of a proper sewerage system has seriously damaged the beauty of the whole area. The absence of which, combined with general water pollution around Penang, has seriously affected the waters around the jetties which are no longer even suitable for fishing [1]. The main purpose of this thesis is to propose a treatment process and also to recommend long-term operations and maintenance in order to properly deal with the issue of substandard sewage processing.
