- Abstract
- Design standards for rural water supply systems in Latin America were analyzed to determine their ability to select component capacities and design flows sufficient to meet actual demands. Water use data were collected from sixteen communities in Guatemala, Honduras, and Ecuador. The data were analyzed to determine actual values for design parameters, including average use rates, peaking factors and storage volumes. Regressive equations were developed for each parameter as a function of community characteristics. For towns of 300 to 1200 persons, results indicate average use rates on the order of 13 to 32 gallons per capita per day in Guatemala and 52 to 56 gallons per capita per day in Honduras and Ecuador. These demands are 150% to 300% higher than the design standards used by AID and local ministries of health; actual peaking factors and storage volumes are also underestimated. Hence, it appears that water systems in Guatemala, Honduras, and Ecuador will not have sufficient capacities to meet actual demands at the end of design periods as planned; rather, excess capacities will be exhausted prematurely. The underlying cause of this seems to be due largely to existing tariff structures, which are incompatible with design standards, and a lack of community awareness about water use and conservation in rural piped water systems. Various approaches for addressing the problem are recommended but not analyzed in detail.
