Follow used handwashing water from a household drain into the sewer network and a treatment plant, then onward to a river that may reach the sea. This lively children’s song introduces screens, settling particles, helpful microorganisms, and the important fact that treated wastewater is not drinking water.

Microorganisms
Microorganisms are organisms usually too small to see without a microscope, such as bacteria and yeasts. They are not all single-celled or disease-causing.
Sources
Water treatment
Water treatment removes selected pollutants using methods such as settling, filtration and biological processes. Treated wastewater is not automatically safe drinking water.

Song lyrics
Ke mana air bekas cuci tangan?
Busa dan remah masuk ke saluran
Air membawa sabun dan sedikit kotoran
Setelah dipakai, namanya air limbah
Pipa kecil melaju di bawah lantai
Lalu tersambung ke jaringan air limbah
Air limbah menuju tempat pengolahan
Bukan langsung ke sungai atau laut
Usai diolah, dapat lewat sungai ke laut
Saringan menahan remah dan sampah besar
Pasir dan butir berat turun ke dasar
Udara membuat gelembung dalam tangki
Mikroorganisme mulai bekerja
Membantu mengurai sebagian kotoran
Air limbah menuju tempat pengolahan
Bukan langsung ke sungai atau laut
Usai diolah, dapat lewat sungai ke laut
Air lebih bersih, bukan untuk diminum
Dapat masuk ke sungai yang berkelok
Arus membawanya jauh menuju laut
Air limbah menuju tempat pengolahan
Bukan langsung ke sungai atau laut
Usai diolah, dapat lewat sungai ke laut
Perjalanan panjang mulai di saluran
Dari pusaran kecil hingga laut lepas
Language version lyrics
Where did the water from my hands go?
Foam and one crumb slip into the drain
Soap and a little dirt ride with the flow
Used water has become wastewater
A narrow pipe runs underneath the floor
Then joins the sewer network down below
Wastewater rides the sewer to the treatment plant
Not straight to the river or the sea
Once treated, a river may carry it to sea
A screen catches the crumb and larger scraps
Sand and heavier grains settle down
Bubbles of air rise inside the tank
Microorganisms get to work
They help remove some pollution from the flow
Wastewater rides the sewer to the treatment plant
Not straight to the river or the sea
Once treated, a river may carry it to sea
The water is cleaner, but not safe to drink
It may enter a winding river
The current carries it across the land to sea
Wastewater rides the sewer to the treatment plant
Not straight to the river or the sea
Once treated, a river may carry it to sea
A long, important trip starts at the drain
One little swirl, then on toward the sea
