Summary
Specialist profession that inspects and analyzes water quality of septic waste and sewage to confirm compliance with environmental standards.
Description
Water Quality Inspectors (Septic Waste and Sewage Treatment Plants) sample septic waste and sewage, measure and analyze values such as pH, BOD, COD, and SS (suspended solids quantity). Using analytical devices like spectrophotometers, pH meters, and titration equipment, they process samples, aggregate and report the obtained data. They verify if measurement results comply with environmental standards and laws, propose improvements to the treatment process, manage records, and perform calibration and maintenance of equipment. Safety management is required for on-site sampling and reagent handling, and precise laboratory work and accurate data recording are essential.
Future Outlook
Demand is expected to remain stable due to strengthening environmental regulations and growing social interest in water quality management. Introduction of automated analysis technologies using IoT and AI is advancing, creating demand for personnel with advanced analytical capabilities.
