The management of the sewerage services in Malaysia has undergone drastic changes with the introduction of the Sewerage Services Act (1993). Sewerage Services in Malaysia is now managed by Indah Water {Consortium (IWK), a private company which has been fully acquired by the government. Measures are being implemented by IWK to upgrade the facilities related to sewerage services. New, bigger and more efficient centralized wastewater treatment plants (WWTPs) will be constructed to replace the existing 8000 smaller plants. This will result in increased transport time, thus allowing for possible significant microbial processes to occur during transport. This thesis presents the methodology and results of studies on wastewater quality changes under anaerobic condition in the bulk water phase of municipal wastewater as it occurs in sewers. Wastewater samples for the study was taken from sewers or from the wastewater treatment plant (WWTP) at Jalan Ilmu, UiTM Shah Alam. Two types of batch reactors were used. One reactor subjected to aerobic condition, used to investigate the COD-fraction of the wastewater. Another reactor was used to investigate sulfate utilization in the wastewater.
