1. What demand must actually be met?
Population, domestic uses, community services, productive activities and future growth should be translated into daily volumes and peak demand.
2. Is the source sufficient year-round?
A one-time yield is not enough. Seasonality, recharge, competing uses and abstraction constraints matter.
3. What is the raw-water quality?
Quality drives treatment-train selection and the monitoring level required before distribution.
4. What energy for pumping?
Grid, solar, hybrid or other options should be compared on availability, whole-life cost, maintenance and continuity.
5. Where and how much storage?
Storage absorbs demand variation and can support network pressure. Its location is both a hydraulic and economic decision.
6. How should water be distributed?
Lengths, diameters, elevation differences, minimum pressure and service points shape the network.
7. Who will operate the service?
Skills, spare parts, procedures, quality control and financial organization should be defined before commissioning.
8. How will service quality be measured?
Availability, volumes produced and sold, losses, water quality, repair time and collection rate are useful indicators.
