Bangkok, ONWR warns to watch out for rising seas and salt water encroaching on rivers during 25 – 30 Apr. 2024. As for the problem of salt water encroaching in the province. Chachoengsao and Samut Prakan Accelerate the pumping of water with salinity values ??exceeding the standard to the sea and receive water from the Pasak Cholasit Dam and the Chao Phraya River to increase the amount of water for diluting and expelling salt water.
Mr. Surasee Kittimonthon, Secretary-General of the National Water Resources Office (ONWR), said that Accelerate the resolution of the situation of salt water encroaching into the Prawet Burirom Canal and its branch canals. Following the incident, the temporary embankment blocking the Prawet Burirom Canal collapsed. This has affected saltwater intrusion, especially in Mueang Chachoengsao District, Ban Pho District, Bang Pakong District, Chachoengsao Province, and Bang Bo District, Samut Prakan Province. ONWR has set up a temporary water resource management unit in times of crisis a
t the project. Water and maintenance of Phra Chaiyanuchit, Chachoengsao Province, in order to fully integrate all relevant agencies to solve problems. By installing a water pump to expedite pumping of water with salinity exceeding the standard to the sea and receiving water from the Pasak Cholasit Dam and the Chao Phraya River to increase the amount of water for diluting and expelling salt water.
In addition, natural microorganisms or EM are used to treat water quality and reduce salinity as the Fisheries Department has prepared maps showing appropriate salinity in each canal. For fish and aquatic animal farmers to safely pump water for use. At this time, the water quality in each area has improved continuously compared to the salinity measured on April 12, 2024, in the Khlong Preng area from the original 19.63 grams per liter to only 0.88 grams per liter, Khlong Prawet Burirom. From 28.04 grams per liter to 6.51 grams per liter, Khlong Chuat Phrao from 14.40 grams per liter to 2.55 grams per liter, leaving
only the area of ??Khlong Phraya Nakharat 1 and 2 and Khlong Phraya Samut that still have high salinity values. from solving problems with full efficiency It is expected that the situation will return to normal within this week.
For checking the quality of water for consumption on the Chao Phraya River at the Samlae pumping station. within standard criteria Water for agriculture at the Tha Chin River at the Chinda Pak Khlong Floodgate Station is within standard limits. The Mae Klong River at Amphawa Station is within standard limits. The Bang Pakong River at Bang Khang Temple Station is within standard limits.
ONWR has issued a warning to watch out for rising seas and salt water encroaching on the river during the period 25 – 30 April 2024, by keeping an eye on areas at risk of flooding in communities outside the dike lines and without dikes. Water (fault line) in the area of ??Samut Songkhram, Samut Sakhon, Nakhon Pathom, Nonthaburi, Bangkok and Samut Prakan As for monitoring of saltwater encroachment affe
cting water quality for consumption and agriculture, monitor the areas of the Chao Phraya, Mae Klong, Tha Chin and Bang Pakong rivers.
Mr. Det Lekwichai, Deputy Director-General of the Royal Irrigation Department, said Problem of salt water encroachment in the province. Chachoengsao and Samut Prakan improved respectively. It accepts water from the Chao Phraya River through the Prem Prachakorn Canal and the Bueng Farang Floodgate. To dilute the salinity Ready to integrate with the Provincial Disaster Prevention and Mitigation Office. Samut Prakan v. Bang Bo and the local administrative organization made a temporary embankment. Ready to install a water pump in the subdistrict area. Bang Phli Noi 2 points and Ban Rakat Subdistrict 2 points. Accelerate the pumping of salt water from the pan basin area and pump it from Khlong Phraya Nakharat into Khlong Bang Phli Noi. before pushing the water out to sea through the Nang Hong Floodgate and Phraya Wisut Pumping Station.
At the same time, water is pumped in various
canal branches. Passing Chonlahan Phichit Pumping Station and Khlong Dan. When water from the upper reaches flows down To push saltwater to flow faster into the sea. Until the situation returns to normal.
In addition, it hastened to add water into the Raphiphat Canal to help agricultural areas in Nong Suea District, Pathum Thani Province, after some water was transported from the upper area to help push saltwater into the Prawet Burirom Canal, Chachoengsao Province, to restore the system. Ecosystems that are urgently damaged by salt water In addition, the current weather conditions are quite hot and are at the end of the dry season. As a result, water in the water delivery canal is used more than usual. causing the water level in the canal in the district Nong Suea is rapidly decreasing.
Currently, some water from the upper reaches has flowed down to the lower areas. To replace water that was previously drained The Rangsit Nuea Water Delivery and Maintenance Project has therefore adjusted the amount of wate
r into the Raphiphat Junction Canal so as not to affect farmers and water users as a whole. As a result, the water level in the canal increased. Water can now be distributed into irrigation canals connected to the main canal. Along with organizing water pumping shifts to receive water thoroughly.
There are also plans to install additional water pumps at the mouth of the canal. So that the area at the back of the canal receives water thoroughly as well. Therefore, please be sure that The path that water flows through will not affect water use in the area.
As for the high sea level during 25 – 30 April, this will not affect the solution of the salinity problem in the province. Chachoengsao and Samut Prakan due to building embankments and closing flood gates. Do not allow salt water to overflow again. At the same time, the water in the area accelerates and accelerates pushing towards the sea.
