Most relevant

• Chemistry - Water treatment workers use chemicals to treat both clean water and sewage, and need to understand how different substances react and dissolve in water. They monitor chemical levels, adjust dosages, and ensure water meets strict safety standards before it reaches people's taps.
• Biology - Water treatment workers use microbes as part of the treatment process, particularly in breaking down sewage and organic waste. They also need to understand how bacteria and other microorganisms can contaminate water supplies and how biological processes help purify it.
• Mathematics - Water treatment workers take readings, calculate chemical dosages, and monitor flow rates to ensure water is treated correctly. They work with measurements, ratios, and data records on a daily basis to maintain safe and efficient operations.
• Environmental Science - Water treatment workers play a direct role in protecting the environment by ensuring waste water is safely processed before being released back into rivers or the sea. Understanding water cycles, pollution, and ecosystems helps them appreciate the wider impact of their work.
• Engineering - Water treatment workers operate, maintain, and repair the pumps, filters, tanks, and control systems that make up a treatment plant. Understanding engineering principles helps them keep complex machinery running and troubleshoot problems when equipment breaks down.

Also relevant

• Design and Technology - Water treatment workers use tools and equipment to maintain and repair tanks, filters, and mechanical systems. Practical skills in working with materials and understanding how systems are constructed are valuable in this hands-on role.
• Physics - Water treatment workers deal with fluid dynamics, pressure systems, and filtration processes that rely on physical principles. Understanding how liquids flow, how pumps generate pressure, and how energy is used in treatment processes supports their day-to-day work.
• Geography - Water treatment workers benefit from understanding how water moves through the landscape, including river systems, drainage basins, and groundwater sources. Geography also covers topics like water scarcity and resource management, which are central to the water industry.
