1、Protect our drinking water.
The water that enters the drainage system through the sewers ends up in our rivers and lakes, and most of it is untreated.
2、Don't throw away the battery at will.
A button cell can pollute 600,000 liters of water.
3. Do not throw rubbish into the toilet, including food residue, medicine, edible oil, cigarette end, sand, paint, paint, motor oil, machine oil, fertilizer or insecticide, cotton cloth and handkerchief, etc.
These substances will make sewage treatment more difficult.
4、Don't throw cigarette butts into the water.
Cigarette butts release pollutants in water and take years to break down.
