Metropolitan Waterworks Authority

What Metropolitan Waterworks Authority does

Metropolitan Waterworks Authority (MWA / กปน.) is a Thai government state enterprise under the Ministry of Interior responsible for producing, transmitting, distributing, and selling treated water across the Bangkok metropolitan area, specifically serving the provinces of Bangkok, Nonthaburi, and Samut Prakan. Its core operations span raw water intake, treatment at facilities including the Bangkhen Water Treatment Plant and Mahasawat Water Plant, and a transmission/distribution network delivering potable water to residential, commercial, and industrial customers. The authority is supported by an ISO/IEC 17025-accredited laboratory, performs water quality testing at three times the frequency of WHO standards, and operates a real-time water quality monitoring system (TWQ) that publishes data every 10 minutes via a public web portal and mobile interface. Geographic reach is delivered through 18 branch offices, a 24/7 call center (1125), an e-services portal (eservicesapp.mwa.co.th), the MWA onMobile application, and multiple bank and payment intermediaries.

MWA's business model is anchored in consumption-based monthly water tariffs set across usage tiers for residential, business, and industrial segments, supplemented by a diversified portfolio of ancillary business services — ISO/IEC 17025-certified water sample analysis, water meter testing and calibration, tank cleaning, pipe survey and leak repair, land and building rental, advertising media, and a Water Saving Label certification program for plumbing fixtures. It distributes these services through both physical branches and digital self-service channels, and pursues an extensive corporate governance program including anti-corruption, whistle-blowing, data governance, digital governance, personal data protection, and business continuity policies published in 2025. Strategic activities include the 9th Master Plan Improvement Project for water system enhancement and a 2025-07-06 partnership with Metropolitan Electricity Authority (MEA) to modernize GIS database systems, positioning MWA as a regulated monopoly utility progressively digitizing its operational and customer-facing infrastructure.
