Cabinet approved the 160-billion-baht Chai Nat–Pasak–Gulf diversion scheme on 29 Sept 2026. Construction is due to start in fiscal 2027 and take eight years. About 70% will be borrowed and 30% from the budget. NESDC review and land-expropriation disputes could delay it. For a small firm, this is a long-run item: watch for land acquisition and construction-sector demand in Saraburi, Nakhon Nayok and Chachoengsao, and flood-risk planning for sites in the Chao Phraya Basin.
