Introduction to all Handpumps
There are many handpumps available for both households and larger communities. Below are Medium handpumps, from a 20 to 50 meters depth. Shallow pumps, 0-20m, and Deep pumps, 50-100m are also available. The household-sized handpumps are for smaller groups, and the community ones are more robust and durable for groups up to 300 people. However, keep in mind the following qualities in choosing the right handpump for your situation:
- Corrosion resistance: Pumps should be corrosion-resistant. Iron taints water and food, stains clothing, and tastes bad.
- User group: Choose a pump for a small, medium, or large (300 people) group of users.
- Pumping lift: Depth of the water table determines pump depth. Deeper pumps can be more expensive.
- Ease of repair: Household repairs require different organisation and maintenance responsibilities than community repairs.
- Yield, user preference: Users prefer pumps that have a high yield and an attractive look and feel.
