During the rainy season, Bangkok tends to experience flood problem in the flood-risk areas on the main roads. Therefore, the Bangkok Metropolitan Administration (BMA) has accelerated to solve the problem by acquiring the water retention areas or “Kaem Ling” (which means “Monkey Cheeks” in Thai). It is part of the measures to prevent flood by adopting the principle of the Kaem Ling Project (Monkey Cheeks Project) of His Majesty King Bhumibol Adulyadej The Great (Rama 9). The BMA has implemented project as well as expanded and developed the results of the project by constructing underground water banks and water pumping stations, enlarging sewer and drainage capacity and structures and enlarging additional water routes in the flood risk areas of total 3 points as follows:
Point 1: Ratchadaphisek Road in Chatuchak District, at the area of public park under the Ratchadaphisek Road – Vibhavadi Road Intersection Overpass, and Apha Phirom Road Pumping Station where the water flow into Lat Phrao Canal.
Point 2: Pracharat Sai 2 Road in Bang Sue District, on the left side of Rim Khlong Prapa Road, drainage pipe junction point to discharge water into Khrua Ta Kaen Canal, near Tao Poon MRT Station, and Krungthep-Nonthaburi Road in the area of Bang Pho Canal.
Point 3: Phaya Thai Road, Phetchaburi Road, Sri Ayutthaya Road, Ratchathewi District at Phaya Thai Road in front of the Department of Livestock Development, water pumping station next to the Indonesian Embassy, and at Sri Ayutthaya Road in front of Phaya Thai Police Station.
Currently, the BMA has a total of 33 monkey cheek projects, consisting of 31 water reservoirs and 2 underground water banks, which can support 13.54 million cubic meters of water. Meanwhile, 5 monkey cheek projects are in progress of construction. The BMA has a plan to propel additional projects in 10 sites and six of them have been completed and ready to use. The 4 Monkey Cheeks Ponds and 2 underground water banks are Monkey Cheeks at Pracha Niwet Pond, Monkey Cheeks at Suea Dam Pond, Monkey Cheeks at Rang Khe Pond, Monkey Cheeks at Friendship Housing Estate Pond, Water Bank under Bang Khen Police Station, and Sutthiphorn 2 Water Bank.
The BMA has continuously monitored flood prevention operations in the areas of Bangkok. Once the construction projects are completed, they will be able to solve the flood problem in the areas of Bangkok in a sustainable way.
