Domestic depletions were about 42 percent of domestic withdrawal requirements. The Upper Main Stem Subregion had the largest subregional domestic requirements. There are numerous factors affecting domestic water requirements. Such factors as available water supply, metering, water pricing policy, water-use regulations, personal per capita income, lot size, population density, family size, sewering, number of plumbing facilities, and climate are significant. 1/ The policies of municipalities and water distribution agencies relating to metering, water pricing, water-use regulations, and land-use regulations can act as controls on municpal-domestic water use. 2/ Metering of municipal-domestic water is common practice throughout the Region. It is significant that the rural-domestic water requirements of the Regional Indian population, located almost exclusively in the San Juan-Colorado Subregion, are largely influenced by the lack of adequate plumbing facilities. 1/ References: 4, 23, 24, 25, 30, 33, 41. 2/ References: 1, 4, 24, 30, 33. |
