Metropolitan Waterworks Authority (MWA) Service Connections
~2.4M connections (Bangkok Metro)
The Metropolitan Waterworks Authority (MWA) serves approximately 2.4 million metered connections across Bangkok, Nonthaburi, and Samut Prakan — covering a combined population of roughly 10 million people. MWA produces and distributes treated surface water from the Chao Phraya River and Mae Klong River systems through its Bang Khen and Mahasawat treatment plants, with combined capacity exceeding 5 million cubic metres per day. Non-revenue water (NRW) has been a persistent challenge, historically running at 25–30% before recent pipe-replacement programmes reduced it to approximately 20–23%. MWA is a state enterprise under the Ministry of Interior.
