Introduction: ISO Certifications for Water Treatment Services
Water treatment services cover a wide spectrum, from municipal water supply and sewage treatment to industrial water recycling and desalination. With water scarcity affecting over 2 billion people worldwide, the sector is under pressure to deliver safe and efficient water solutions. According to market research, the global water treatment industry is projected to exceed USD 500 billion by 2030, driven by stricter environmental rules and rising demand for clean water in industries such as food, pharmaceuticals, and energy.
This sector faces challenges including contamination risks, chemical management, environmental impact etc. ISO certifications help water treatment providers establish transparent, internationally recognized systems and assure customers and regulators of consistent standards.
Water treatment services are vital to public health and industrial operations—ISO certifications provide structured systems to ensure safety, compliance, and reliability.
