Table E- 0 - 10 in Saidabad Water Treatment Plant Project, Phase III

Table E-0-10: Monitoring issues/ requirements during operation phase of the project (Originally Table 8)Environmental IssueMonitoring requirements/issuesDisposal of treatment waste› Regular (once every three months) assessment of the characteristics of sludge through TCLP test to ensure that it is not hazardous.› Monitoring of discharge parameters of liquid residuals from sludge drying operations.› Studies to explore the possibility beneficial sludge disposal options (e.g., land application), and in designated landfills (coordinating with the Dhaka City Corporation)Treated water quality› Regular monitoring of treated water quality (as part of the ongoing regular plant operation) to ensure that it is safe for public consumption.› Modification of treatment process (e.g., increase/decrease alum dose of chlorine dose), if needed.Raw water quality› Regular monitoring of raw water quality, as part of ongoing regular plant operation.› In association with the Department of Environment (DoE), developing of a long-term management plan for the protection of raw water quality in Meghna River (including restriction on establishment of industries producing liquid effluent within certain reaches upstream and downstream of the intake point).Generation of additional volume of wastewater as treated water supply increases› This issue should be taken into consideration in the ongoing planning and implementation activities of DWASA aimed at expanding sewerage network and treatment facilities in Dhaka city. This would obviously necessitate additional sewage treatment plant at appropriate locations.Safety of water distribution network› Monitoring and detection of leaks and expansion and up-gradation of water distribution network of, as part of DWASA’s regular monitoring and expansion works.
