Five high-capacity water pumps are being urgently installed at the Khlong Mon watergate to resolve flooding issues in Prachinburi and Chachoengsao provinces.
On 22 Oct 2026 GMT+7, reports indicated that severe flooding in Ban Sang district, Prachinburi Province, had persisted for nearly a month. This affected residents across five subdistricts: Krathum Paew, Bang Pla Ra, Bang Kham (where rainbow-colored industrial effluent had spread), Bang Yang, and Bang Tan. Residents there are unable to leave their homes by land and must use boats. Meanwhile, in Bang Khla district, Chachoengsao Province, adjacent to Bang Tan subdistrict, high floodwaters have also persisted with no sign of receding to normal levels.
To address the problem, Krit Bamrungsalee, chief of Hua Sai Subdistrict Administrative Organization in Bang Khla district, Chachoengsao Province, coordinated to secure funding for installing five high-capacity water pumps at the Khlong Mon watergate of the Bang Phluang irrigation project in Ban Sang district, Prachinburi. This area borders Bang Khla district and pumps water into the Prachinburi River.
Krit Bamrungsalee explained that Khlong Mon is part of the Bang Phluang watershed. Water flows from Hat Yang in Dong Krathung Yam subdistrict, Sri Maha Phot district, then through Phai Cha Luead subdistrict, Si Maha Phot district, into Khlong Krathum Paew in Ban Sang district, and finally into Khlong Mon near Wat Sak Kaeng Ngam. This stream aims to quickly discharge water into the Bang Pakong River.
With support from the Minister of Defence, General Dul Boonthamcharoen, and the Deputy Minister of Interior, directives were given to urge the provincial governor to expedite the project and allocate budget for rapid pumping. If water can be discharged quickly, roads will dry, and conditions will normalize. Currently, 97% of this area is flooded; only about 10% of rice paddies have been harvested, with the rest damaged. Particularly, prawn farms raising giant river prawns, black tiger shrimp, and white shrimp have suffered severe losses. Damage in Hua Sai subdistrict alone is estimated at over 300 million baht.
Efforts will focus on pumping water into the Bang Pakong River as fast as possible. Floodwaters rise for four hours and recede for four hours, but currently water recedes for eight hours and rises for only four. Accelerating drainage will reduce damage to mango orchards and rice fields. By early December, saltwater intrusion will increase. Farmers, many indebted to BAAC, have already received compensation and plan to reinvest in planting rice again. This will help restore livelihoods. Regarding relief supplies, the Subdistrict Administrative Organization is ensuring all over 2,600 flooded households receive assistance.
At present, stagnant water is causing odors, and Aedes mosquitoes are increasing, leading to foot rot disease. Discussions with the hospital have resulted in delivery of medication for foot rot and citronella-based mosquito repellents to assist residents. Registration for flood relief aid is ongoing, with work continuing through weekends without pause.
