    Reading
    texts: Clean water and sanitation (SDG 6)

    Read Text A and Text B. Underline words
    you do not know. Try to guess their meaning from the context. After reading,
    complete the tasks in Appendix 2.

    TEXT A – From river to tap: the city water
    journey
    In many towns and cities, drinking water starts in a
    river, lake, or underground well. Before it reaches our homes, it is cleaned at
    a water treatment plant. First, water is screened to remove leaves and large
    pieces of rubbish. Next, it is filtered so that small particles of dirt are
    taken out. After that, the water is disinfected (often with chlorine or UV
    light) to kill germs that can cause disease. Finally, the clean water is tested
    and pumped through pipes to schools and houses.
    Good infrastructure is important: old or broken pipes can let contaminants in
    and cause leaks. That means clean water is wasted before it even gets to
    people. Saving water at home and at school also helps, because treatment uses
    energy and money.

    TEXT B – Sanitation: why toilets and
    wastewater matter
    Clean water is only one part of a healthy community.
    Sanitation means having safe toilets and a system to collect and treat
    wastewater. Wastewater is used water from sinks, showers, washing machines, and
    toilets. If it is released untreated, it can pollute rivers and seas and spread
    waterborne diseases.
    At a wastewater treatment plant, solid waste is removed, then the water is
    cleaned using bacteria and filters. In the end, cleaner water can be returned
    to nature. Everyone can help: never flush wipes, plastic, or oil; use only the
    needed amount of water; and report dripping taps. Good hygiene, like washing
    hands with soap, is one of the easiest ways to protect health.
