Before we talk about water, let us understand what an industry is. An industry is a big place, like a factory or a large workshop, where people work together to make things we use every day. Think of a place where bread is baked in huge ovens, or where your plastic toys are made, or where "pure water" sachets are filled. These big places are called industries.
Just as we need water at home to bathe and drink, industries need a lot of water to do their work. Without water, many factories would have to stop working. Water is like a "super helper" for people who make things.
In every factory, cleanliness is very important. For example, in a factory that makes fruit juice, the oranges and pineapples must be washed thoroughly with clean water before they are squeezed. Also, the big machines used to mix food must be washed every day so that the food stays healthy for us to eat. Water helps to wash away dirt and germs from the floors and the machines.
Sometimes, water is part of the thing being made. If you look at a bottle of medicine or a pack of juice, water is mixed with other things to create the final product. In a bakery, the baker mixes flour, sugar, and water to make the dough for bread. Without water, the bread would just be dry powder!
When big machines in a factory work for a long time, they get very, very hot—just like how you feel hot after running a race. If the machines get too hot, they might break. Industries use cold water to run through or around these machines to keep them cool so they can keep working safely.
Have you seen people building a house or a big school? They use water to mix cement and sand to make the blocks strong. The "Block Industry" in Nigeria uses a lot of water to make the solid blocks we use to build our homes.
Scenario 1: The "Pure Water" Factory In Nigeria, we see many "Pure Water" (sachet water) trucks. In this industry, water is the main product! The factory takes water from the ground, uses big filters to make it very clean, and then uses machines to put the water into sachets. Here, water is used for cleaning the environment and as the actual product we buy to drink.
Scenario 2: The Car Wash Industry Think about a professional car wash. This is a small industry. They use high-pressure water hoses to blast mud off cars. They also mix water with soap to make the cars shiny. Without a large supply of water, the car wash business cannot work.
Scenario 3: The Textile (Cloth) Industry To make the beautiful "Ankara" or school uniform fabrics we wear, the cloth must be dyed with colors. The factory mixes bright dyes with large amounts of water in big vats to soak the cloth. Water helps the color go deep into the thread.
How to "Act Like an Industry" (The Cleaning Station) In a factory, washing must be done in a specific order. You can practice this at home with your plastic toys:
