The Jakarta Flood Canal (Indonesian: Kanal Banjir) refers to two canals that divert floods from rivers around Jakarta instead of going through the city. This first flood control channel was designed by Hendrik van Breen, engineer at the Burgelijke Openbare Werken or BOW (later the Ministry of Public Works), after a big flood hit the city on 13 February 1918.
With help of Netherlands Engineering Consultants, the "Master Plan for Drainage and Flood Control of Jakarta" was published in December 1973. According to this plan, flood control of Jakarta would revolve around two canals encircling the city.
The canals divert the water flowing from the south around the city and into the sea. These canals are known as West Flood Canal and East Flood Canal. Other measures to control floods in Jakarta include reservoirs and pumps in areas below sea level. This system built in 1983.
The West Flood Canal marked the southern boundary of the Menteng residential area. The flood canal was included in the 1918 Batavia city plan and constructed in 1919. It runs from the floodgate in Manggarai, via Pasar Rumput, Dukuh Atas, Karet Kubur, Tanah Abang, Tomang, Grogol, and Pademangan to the sea at Muara Angke. Another floodgate is located in Karet. A still existing bronze plaque on the Manggarai floodgate honours Van Breen and commemorates the canal's first use in diverting the flood of 1919.
In the 1973 master plan, a system of canals was planned to cut to the flow of water in West Jakarta. This was a continuation of Van Breen's canal and would later be known as the West Flood Canal. The construction was delayed by problems in clearing the heavily populated area. After a flood in January 1979, the central government and the provincial government of Jakarta revised the West Flood Canal plan by the construction of the Cengkareng drainage system.
