Sri Lanka, officially Democratic Socialist Republic of Sri Lanka, formerly Ceylon, is an island republic in the Indian Ocean. Globally, Asia has the lowest overall figures of safe water supply coverage and sanitation coverage: almost two-thirds of those without access to improved water supply and approximately 80% of those without access to improved sanitation. However, in Sri Lanka, 81% of total population has adequate sanitation facilities and 78% are using improved drinking line water sources (UN 2002). The lack of good sewage treatment is a cause of sickness and disease, a major environmental threat to any country's water resources, and a fundamental stumbling block in the advancement of human dignity. The importance of sewage treatment must be understood by both public and government. Currently there is a positive trend in treating sewage. Sewage treatment in Sri Lanka has been developing strongly in the last two decades. Still there are many challenges to be overcome associated with the sewage treatment industry. Public awareness is the most important issue. The National Water Supply and Drainage Board which is under the Ministry of Urban Development and Water Supply is the main governing agency in Sri Lanka for sewage treatment and has been actively involved in its improvement. Also, local government authorities, the Environmental Protection Authority, non governmental organizations and the public are involved in the drive to achieve worlds' best practice in this area. I had been working at Sewerage Section of Central Engineering Consultancy Bureau, Sri Lanka since graduation, March 2002. At that time, I was really interested to do some work related to sewage treatment in Sri Lanka. It motivated me to choose 'Sewage Treatment in Sri Lanka' project as my hydrology and water resources supervised project. / Thesis (MEng(HydrologyWaterResources)--University of South Australia, 2005

In this thesis, detection of active water-borne bacteria was achieved by combining flow cytometry with vital dyes that characterise the metabolic status of cells. Following optimisation, these techniques were applied to investigate the activity of bacteria exposed to disinfection, both in the laboratory and in real systems. Raw and potable waters from various locations around South Australia were then analysed to investigate relationships between numbers of active bacteria and those detected by traditional culture-based techniques. / Thesis (PhDAppliedScience)--University of South Australia, 2005.
