Project Description

The Bangkok Metropolitan Administration (BMA) has planned and continuously implemented the construction of centralized wastewater treatment systems as well as the improvement of community wastewater treatment systems to rectify water pollution in canals and river. Rapid growth of suburban areas, especially the Minburi community area, resulted in the discharge of untreated wastewater from houses and business establishments into Khlong Saen Saep, Khlong Sam Wa, and Khlong Song Ton Nun in Minburi, Khlong Sam Wa and Lad Krabang districts, causing water pollution problems particularly in the dry season. Water pollution is one of factors contribute to the risk of diseases in communities located by Bangkok main canals.

Therefore, the Department of Drainage and Sewerage, BMA, had proposed the implementation of Minburi Wastewater Treatment Project with the objectives of improving the canal water quality within the study area. Wastewater generated in the study area, which covers an area of approximately 2.85 km2 comprises Minburi and Saen Saep subdistricts of Minburi district, would be collected and treated with the wastewater treatment capacity of 10,000 cu.m./day. A plot of land at Khlong Saen Saep, Minburi Regulator had already been allocated for a wastewater treatment plant.
As a result of the review of existing drainage system and the topography of the project area, the Consultant had proposed to adjust the project boundary in accordance with the topography of catchment area. Thus, the project area was adjusted from 2.85 km2 per the TOR to 2.93 km2 and the future expansion area from 23 km2 per the TOR to 29.76 km2.
