Water from air for schools, clinics and communities
Published 1 November 2026 · 7 min read
For a school or clinic without a reliable supply, safe drinking water is not a convenience. It decides whether learners stay in class and whether patients can be treated. Water from air can provide it where there is no pipe and no borehole. Here is how to plan a project that keeps working after the ribbon is cut.
Short version: plan drinking water at about 2–3 litres per person per day, size for the driest months, secure power for night-time running, and budget for filters and spare parts from day one. A 1000L unit covers the drinking water of several hundred people in a good climate.
How much water do you need?
A water generator supplies drinking and cooking water, not washing or flushing. As a planning figure, allow about 2–3 litres per person per day for drinking, more in hot weather, and more for clinics that need water for patient care.
| Site | Drinking water need | Typical system |
|---|---|---|
| Small clinic or crèche (50–100 people) | 150–300 L/day | 1 × 250L or 1 × 1000L inland |
| Primary school (400–600 learners) | 800–1,500 L/day | 2–3 × 1000L inland, 1–2 on the coast |
| Large school or community point (1,000+ people) | 2,000–3,000 L/day | 5000L or several 1000L |

Power
- Industrial units need three-phase power: about 8.7 kW per 1000L.
- Production peaks at night, so solar-only sites need batteries (see our solar guide).
- Where power is unreliable, store water in clean tanks so supply continues through outages.
Funding proposals
Many projects are funded by grants, corporate social investment or donors. A strong proposal includes:
- the number of people served and litres per person
- expected output in summer and winter, not just the rated figure
- the full budget: equipment, import, installation, power, storage and five years of filters and parts
- who owns, operates and maintains the system after handover
SkyTap prepares budget quotations for funding applications, with equipment, logistics and running costs itemised.
Keeping it running
Most failed water projects fail on maintenance, not equipment. Before installation, agree:
- A named caretaker trained to change filters and clean the unit.
- A filter budget for at least five years. Filters are inexpensive compared with the machine, but they must be replaced on schedule.
- Water testing by an accredited laboratory, especially where water is served to children or patients.
- Remote support: SkyTap supplies parts and remote technical support; local electricians and plumbers handle on-site work.
Questions
How much drinking water does a school need per day?
Plan for about 2–3 litres per learner per day for drinking, so a school of 500 learners needs roughly 1,000–1,500 litres a day.
Can a water generator be funded through a grant?
Yes. Many projects are funded by grants or corporate social investment. SkyTap prepares itemised budget quotations for funding applications.
Who maintains the system after installation?
The school, clinic or community appoints a caretaker. SkyTap supplies filters, spare parts and remote technical support.

Sources and assumptions. Output and power figures are the manufacturer's tested values for SkyTap units (1000L: about 1,000 L/day at 30°C and 80% RH, 600 L/day at 27°C and 60% RH, 135 L/day at 25°C and 30% RH, 8.7 kW). Electricity costs and solar yields are planning assumptions stated in the text, not quotes. Prices are SkyTap's published unit prices at the time of writing and are confirmed in a written quotation.
