"Tolerate litter, and you'll tolerate anything."

- Millard Fuller, late Founder of Habitat for Humanity

It's time to take collective responsibility to care for the public spaces we share.


Join us for Big BlockWalk 2022, the largest virtual community clean-up across Singapore! As one of the culminating events for the Public Hygiene Council's Keep Clean, Singapore! campaign, take this virtual volunteering opportunity to clean up your neighbourhood or favourite green space.

We are also taking this time to advocate for personal ownership over our shared spaces. We aim to rally 1,000 participants (and more, if possible) to show everyone that we as society, do indeed, care.

This event is suitable for all ages, and will be conducted virtually over Zoom.


Big BlockWalk will be held virtually over Zoom. You will receive the Zoom link along with event instructions after successful registration.​

  • Go solo with your friends/family/neighbours

  • Choose your own neighbourhood or green space 

  • Connect with volunteers islandwide over Zoom

Big BlockWalk is a family-and-children friendly volunteering programme. We welcome children as young as kindergartners, accompanied by parents.


Together, let's love our shared home beyond the four walls.
