HCWC

Humanitarian Collapsible Water Container

A collapsible water container that integrates filtration, adaptable storage, and transport, expanding from 8 L to 14 L.

“Design a personal-scale water filtration solution.”

01 — PROBLEM

Understanding the Problem

For displaced communities, accessing safe water involves more than collection. Long distances, heavy loads, and contamination risks make everyday water management physically demanding.

How could we make water collection, transportation, storage, and filtration more accessible?

02 — RESEARCH

Field testing

I recreated a water collection journey in a local park to identify firsthand challenges in carrying, handling, and using conventional buckets on uneven terrain.

Key findings

  • Uneven weight distribution, uncomfortable grips, contamination risks, and physical strain.

04 — PROTOTYPE

Prototyping

Through iterative 3D printing, laser cutting, and physical testing, I developed a sliding mechanism that expands the container from 8 L to 14 L, adapting its capacity to different users.
