The income level of the consumer influences water use for
several reasons. First, it is generally believed the consumer
in a higher valued area is likely to have more water using
appliances. The increased number of appliances is thought to increase
the overall domestic use and simultaneous domestic demand. Secondly,
domestic use in areas served by public sewers is believed to be
approximately 25 percent higher than in areas using septic tanks.
Consumers on septic tank systems are apparently concerned that their
underground disposal system will require more frequent cleaning and
therefore tend' to use less amounts of water for domestic purposes.
Thirdly, the consumer in a higher valued area probably has a larger
lot with much of it in lawn. A larger than average lawn is a
contributing factor towards an overall increase in total irrigation
requirements. Income breakdown for Delta County, as listed in the
1973 Colorado Yearbook, is shown in Table IV-3.
