| Abstract | The study deals with the construction and the operation of an open test cell to identify the general behaviours such as leachate generation and characterization, gas emissions, and the performance in the open dump conditions under the tropical climate condition. An open test cell was constructed with four elements: liner system, leachate collection and removal system, gas collection system and simple cover system capable of rainfall percolation. This open test cell was constructed by using the locally available construction materials and filling the domestic waste, and monitored for a period of rainy and dry seasons. Leachate generation, leachate characteristic, gas emission, waste settlement variation and quality of groundwater near the test cell were monitored. After six month of monitoring, higher leachate generation was observed in the rainy season and little in dry season. The monitoring results of pH, conductivity, alkalinity, TSS, COD and TKN indicate the process of the waste decomposition or biodegradation within the test cell. The results of gas emission showed that more CH₄ and CO₂ were detected in the bottom level and indicates that there exist aerobic condition in the top level, transition phase from the aerobic to anaerobic phase in the middle level, and the acid generation phase in the bottom level. The settlement gradually increased during the dry season. The groundwater monitoring results showed that test cells are containing the waste effectually and not affecting the site groundwater. The similar tendencies in pH, conductivity, alkalinity, TSS, COD and TKN were observed from the previous lysimeter tests |
