Khlong Saen Saep is a canal in Bangkok Thailand, connecting the Chao Phraya River to Prachin Buri and Chachoengsao. A portion of the canal is used for public transport by an express boat service in Bangkok. The canal is lined with concrete walkways on either side in many areas where people stroll. In other areas the heavily polluted water oozes into adjacent properties, especially after heavy rainstorms. The canal is connected to many other canals in a large network, though most of the other canals do not have a regular transport service.
