Maria’s Family

Stay-at-home mom, Sells cardboard and vegetables part-time1 husband: Julio (works as contractor)3 daughters / 1 boy (14f: Cami, 10f: Alejandra, 5m, 2f: Sol)1 rabbit: Pepe1 dog: guard dog

Chores:

breakfast lunch: Maria + Sol, others go to schooldinner: family - 2 girls (watching favorite tv show)forgot to cover barrel by latrine, water became contaminated

Inappropriate handling and storage of water leads to contamination and possible illness

Inaccurate measures of chlorine result in ineffective treatment or adverse long term effects from overuse

Dislike for taste of treated water leads to substitution with soft drinks or boiled water with sugar (expensive, time consuming, unhealthy)

Problem: Waterborne illness

Observations

Products designed for this market must be inexpensive and easily accessible, either through local marketplaces and stores or assembled with available materials. To facilitate implementation, products will use existing technologies and products repackaged together for convenience and coordinated use.

We are addressing the conditions in the campamentos that make it difficult to preserve water quality. Water can be contaminated at many points throughout its daily use. Even after treatment, water can be recontaminated though inappropriate storage and handling. We seek to eliminate these contamination risks by designing easy and responsible solutions.

Entry routes of contamination during storage
