Five irrigation projects initiated by His Majesty the King have been in operation for effective water management and improvement of cultivation.
The five projects are located in five provinces, namely Khun Dan Prakan Chon Dam in Nakhon Nayok, Khwae Noi Bamrung Daen Dam in Phitsanulok, Lam Phayang Bhumipat Water Diversion Tunnel in Kalasin, Thoranit Naruemit Sluice Gate in Nakhon Phanom, and Uthokvibhajaprasid Sluice Gate in Nakhon Si Thammarat.
His Majesty the King, accompanied by Her Majesty the Queen and Her Royal Highness Princess Maha Chakri Sirindhorn, presided over the inauguration of the five projects on 7 July 2012. He traveled on board a cruise ship along the Chao Phraya River from Siriraj Hospital to Ko Kret in Nonthaburi to visit riverside communities affected by the severe flooding in 2011. The ship stopped at the Royal Irrigation Department Headquarters in Bangkok, where His Majesty attended the official opening for the five royally initiated projects.
Located in Mueang district in the central province of Nakhon Nayok, Khun Dan Prakan Chon Dam, which was constructed in 1999 and completed in 2005, retains water during the rainy season for use in the dry season. It also contributes to flood control, provides a fish source, and eases the problem of acidic soil.
Khwae Noi Bamrung Daen Dam is located in Wat Bot district in the northern province of Phitsanulok. Construction of the dam was completed in 2009 and the dam helps prevent floods and stores water for agriculture and consumption.
Located in Khao Wong district in the northeastern province of Kalasin, the Lam Phayang Bhumipat Water Diversion Tunnel seeks to ease the water shortage problem, so that local residents will be able to cultivate all year round. It diverts water from Huai Phai reservoir in Mukdahan province to farmland in Kalasin.
Thoranit Naruemit Sluice Gate, located in Tha Phanom district in the northeastern province of Nakhon Phanom, is part of the Kam River Basin Development Project, which aims to store water for agriculture and consumption and tackle the flood problem.
Uthokvibhajaprasid Sluice Gate is located in Pak Phanang district in the southern province of Nakhon Si Thammarat. It is a major sluice gate for the Pak Phanang River Basin Development Project, which was put into operation in 1999. The auspicious name bestowed by His Majesty the King on the sluice gate means ability to separate saline water from fresh water. The project seeks to prevent the intrusion of saline water into the river and retain fresh water to sustain life. It constitutes the starting point for the improvement of the people's quality of life and the promotion of sustainable utilization of the natural resources of Pak Phanang River Basin.
All five irrigation projects have helped tackle water problems and have improved the lives of Thai farmers.
