MWA Bangkok daily water delivery
~6.0M m3/day
Metropolitan Waterworks Authority (MWA) delivers approximately 6.0 million cubic metres per day of treated potable water to Bangkok, Nonthaburi, and Samut Prakan, serving roughly 2.38 million accounts (households and commercial premises) through about 37,700 km of distribution pipes, per MWA 2023 consumer confidence report and Wikipedia compiled MWA statistics. Source water is drawn primarily from the Chao Phraya River at Sam Lae (raw water intake) and treated at the Bang Khen, Mahasawat, Sam Sen, and Thonburi water treatment plants. Non-revenue water (NRW) losses run around 30%, a chronic infrastructure renewal challenge.

What this tells you
Metropolitan Waterworks Authority (MWA) delivers approximately 6.0 million cubic metres per day of treated potable water to Bangkok, Nonthaburi, and Samut Prakan, serving roughly 2.38 million accounts (households and commercial premises) through about 37,700 km of distribution pipes, per MWA 2023 consumer confidence report and Wikipedia compiled MWA statistics.

Non-revenue water (NRW) losses run around 30%, a chronic infrastructure renewal challenge.
What not to do with it
Delivery volume varies seasonally; dry season peaks ~6.3M m3/day. NRW losses on the 30% benchmark are a recurring policy theme for MWA capex prioritisation.
