Cabinet approved on 29 September 2026 the Chai Nat–Pak Sak–Gulf of Thailand drainage canal (270 km, 9 provinces), budgeted at over 165 billion baht, with construction over about 8 years from fiscal 2027 to 2034 under the Royal Irrigation Department. The new "Chao Phraya 2" section runs 135 km from Pak Sak to the Gulf, through 5 provinces (Saraburi, Ayutthaya, Nakhon Nayok, Chachoengsao, Samut Prakan), and needs about 16,208 rai of land and 2,600 households relocated. If your premises, land or warehouse sit along this route, check whether you fall inside the acquisition boundary and watch for compensation notices. Otherwise this is a long-run flood-control and road-access project: note possible construction demand and better drainage in the east of Bangkok over the coming decade.
