A Tiny Toilet Habit That Protects Big Water Systems
To help achieve SDG 6: Clean Water and Sanitation, here’s a micro-action that takes no more than a habit shift: Stop flushing tissues, hair, or floss. Use a bin instead.
Though it seems harmless, flushing non-toilet waste clogs sewer systems, contaminates waterways, and strains water treatment infrastructure. A single flush can carry pollutants straight into rivers or oceans, especially in areas with poor sewage systems.
Why This Small Action Matters
- Globally, approximately 80% of wastewater is released into the environment without being treated or reused. This contributes to water pollution and numerous health and environmental risks. (Source: UN Water)
- A more nuanced global estimate—based on the UNU-INWEH and Utrecht University report—finds that only 52% of wastewater is treated, with treatment levels much lower in low-income countries (<5%) and much higher in high-income countries (~74%).

- In the UK alone, sewer blockages—often caused by non-flushable items—cost Thames Water approximately £18 million per year to clear. (Source: Thames Water)
How to Start
- Place a small bin in or near your bathroom.
- Toss tissues, floss, hair, and cotton pads in the bin—not the toilet.
- Share the habit with housemates or kids.
- Bonus: Label the bin “For Clean Water” as a reminder.
It’s one of the most overlooked ways to protect water—and it starts at home.
Bottom Line
Your toilet isn’t a trash can. One skip = cleaner water for everyone.
