Parliament's budget office says government water spending was about 421,426 million baht over 2017-2023, with 63,421 million baht allocated in 2026 alone. The World Bank puts flood losses at roughly 3% of GDP a year, with Bangkok bearing a disproportionate share. Most water spending is capital investment (87.2%), so delays hit flood and drought outcomes directly. The budget office recommends a single water budget framework by river basin to cut overlap. For a small business, the practical takeaway is flood and drought risk is not falling, so check your own flood-proofing, water supply backup and insurance; the article does not set any new rule or deadline.
