- Long An Water Supply Sewerage Joint Stock Company is a Vietnam-based utility enterprise primarily engaged in the treatment, distribution, and management of municipal and industrial clean water supplies, as well as the design, construction, and maintenance of water supply and wastewater infrastructure. The company operates across several core business segments, offering a comprehensive suite of products and services: extraction, purification, and piped distribution of treated clean water for residential, commercial, and industrial consumers; production and commercial distribution of bottled drinking water; engineering, procurement, and construction services for water supply networks, wastewater drainage systems, and civil technical infrastructure; specialized engineering design, technical consultation, and cost estimation for hydraulic works and piping networks; wholesale and retail distribution of specialized water industry materials, fittings, valves, meters, and piping equipment; inspection, calibration, and testing services for cold water meters; laboratory testing and quality verification of physicochemical and microbiological water parameters; groundwater exploration, testing, and well-drilling services; collection, transport, and treatment of water purification sludge; and auxiliary rooftop solar power generation. Tracing its operational roots to 1956 with the establishment of the Tan An Water Plant, formally established as a state enterprise in 1992, and equitized into a joint stock company in 2013, the organization is headquartered in Tan An City, Long An Province, Vietnam. The company primarily serves residential households, commercial businesses, public institutions, and industrial parks throughout Tan An City and surrounding districts across Long An Province, operating key production facilities including the Tan An Water Supply Plant, Go Den Water Plant, and Binh Anh Groundwater Plant. In recent strategic developments, the company underwent a major corporate ownership restructuring following the acquisition of a 38.06% strategic equity stake by Binh Duong Water Environment Joint Stock Company (BIWASE) from DNP Water, integrating the company into BIWASE's expanded regional water and environmental utility network. Concurrently, the company has advanced operational integrations with regional bulk water conveyance infrastructure—notably connecting distribution channels with capacity from the Nhi Thanh Water Treatment Plant—while executing extensive pipeline extension projects across emerging industrial corridors, implementing non-revenue water loss reduction programs, and deploying digital metering and automated billing systems.
