What Vietnam Water Sanitation & Environment does

Vietnam Water, Sanitation and Environment Joint Stock Company (VIWASE) is a Vietnam-based engineering consulting and infrastructure firm founded in 1969 and headquartered in Hanoi, with publicly traded shares (ticker VWS) on the UPCOM exchange. The company serves Vietnamese provincial and municipal governments, industrial and commercial enterprises, and urban development projects with a full-lifecycle service portfolio spanning water supply, drainage, wastewater treatment, solid waste management, and climate change adaptation infrastructure — covering research, master planning, feasibility studies, survey, design, project management, construction supervision, and environmental monitoring. VIWASE also invests in and operates water treatment assets under BOO/BOOT models (notably the Như Quỳnh water plant in Hưng Yên province), designs and manufactures specialized water and sewerage equipment, and executes construction of water and technical infrastructure works. Operationally, the firm employs over 300 staff including PhDs, engineers, and senior experts, maintains regional offices in Da Nang and Ho Chi Minh City for nationwide coverage, and partners with institutions such as the Vietnam Institute of Water Resources Science. Revenue is generated through professional services fees, managed-service / concession-style returns from BOO assets, hardware sales of specialized equipment, and one-time construction contracts — primarily delivered via direct engagement with public-sector counterparties through Vietnamese government procurement processes.
