Hand Pump Families Served — How Many People Benefit from a Hand Pump?
A hand water pump provides clean drinking water for up to 4 families — typically 16 to 30 people depending on household size. HNCO positions each pump between a cluster of houses, ensuring all beneficiary families can access water within a short walk. This household-scale approach means your £150 donation creates a direct, measurable impact on specific families who will use the pump daily for 10+ years.

Why 4 Families Per Pump?
The 4-family guideline balances several factors:
Water Output Capacity
A hand pump in good condition produces approximately 10-15 litres per minute with moderate pumping effort. This translates to 200+ litres per day with typical usage patterns — enough for 4 families' drinking, cooking, and basic hygiene needs.
Physical Accessibility
HNCO places pumps between houses, typically within 100-200 metres of all beneficiary homes. Serving more than 4 families would require some households to walk unreasonable distances.
Pump Longevity
Limiting usage to 4 families prevents overuse that would accelerate wear on components. This helps achieve the full 10+ year lifespan with minimal maintenance.
Community Ownership
A smaller group of beneficiaries creates clearer ownership and responsibility. All 4 families know each other and can coordinate maintenance and care.
How Family Size Affects Impact
The number of individuals served varies by region due to different household structures:
Pakistan (rural Punjab/Sindh)
Extended families of 6-8 people per household are common. 4 families = 24-32 people.
Pakistan (Balochistan/KPK)
Larger joint families of 8-10 people. 4 families = 32-40 people.
Africa (various regions)
Household sizes of 4-6 people. 4 families = 16-24 people.
Regardless of exact numbers, the pump is sized to meet all beneficiaries' daily water requirements with capacity to spare.
Meeting Daily Water Needs
The World Health Organization recommends 50-100 litres per person per day for all domestic needs (drinking, cooking, hygiene). A hand pump easily meets this:
| Use | Per Person/Day | 4 Families (20 people) |
|---|---|---|
| Drinking | 2-3 litres | 40-60 litres |
| Cooking | 3-5 litres | 60-100 litres |
| Personal hygiene | 10-15 litres | 200-300 litres |
| Total | 15-23 litres | 300-460 litres |
A hand pump can produce 200+ litres per day comfortably. Families collect water 2-3 times daily, spreading usage across morning and evening periods.
