Footprint (counter space required by device)

• The product uses minimal counter space without compromising stability or exceeding the overall height guideline.

Key indicators

• Footprint dimensions are a function of upper and lower container volumes and overall height.
• Footprint dimensions allow the product to meet stability guidelines.
• Footprint provides stability on foreseeable placement surfaces such as floors, counters, chairs, and tables.

Notes and exceptions

• Low-income households may not offer horizontal surfaces such as counters or tables above the floor (varies by region).
• Alternative product formats (such as wall-hung or siphon devices) may minimize product footprint.

Supporting evidence

• Safe Water Project qualitative household research: household dimensions, furnishings and family size.
• Stability test results.
