Bangkok says 38 retention ponds and reservoirs now hold about 13.71 million cubic metres of floodwater: 35 on the east side (7.68 million m3) and 3 on the west bank (6.03 million m3). More capacity is due in 2026 (38,000 m3) and 2027 (162,000 m3). Two planned sites, Khlong Khu Bon and Khlong Bang Chan, were dropped after public hearings were not held and land values rose. If your shop, warehouse or factory sits near a flood-prone area, check the list for ponds near you and plan for drainage and stock protection during the rainy season.
