• County: Archuleta
• Water Efficiency - Doc Type: Application

supported by the US Census Bureau and the Region 9 Economic Development Authority
Survey of Second Homes in Archuleta County.

The Colorado State Demographer has also developed population estimates for
Archuleta County, predicting a growth rate of about 3.5% per year over the period from
2000 to 2030/ estimating that nearly 26/800 full time residents will call the county home
in 2030.

Population estimates for P A WSD are presented in Table 3 based on observed past
growth rates in the P A WSD service area (using EUs), noting that the population
estimates include a very significant transient population of water and wastewater
customers that utilize P A WSD services as they visit the area as tourists and/ or property
owners who reside in the community only on a part-time basis since P A WSD must be
able to provide service during peak demand periods. Development is expected to
continue in the P A WSD service area given the demand for part-time housing and
condominiums, hotel rooms and full time residents. As residential demand increases,
local commercial uses including hotels and restaurants, shops, and other commercial
enterprises are also expected to increase. The total amount of outdoor watering may
also increase over time.

Based on these estimates, the 2030 annual population served by P A WSD is estimated to
be 25/679. Assuming an average per capita water use of 190 gallons per day per person
(gpcd), the population growth represents an additional demand of over 3/200 AF by
2030. This is only an estimate of future water demand. The forecast will be updated and
improved during the preparation of the Water Conservation Plan.

(c) Estimated water savings goals to be achieved through implementation of the Plan

The District is located in the San Juan River basin of Colorado. According to the
Colorado Statewide Water Supply Initiative (SWSI), there is a supply need of 18/800 AF
in the Dolores, San Juan and San Miguel River basins, assuming about 12 percent
reduction in current per capita water use occurs due to ongoing water conservation
measures and programs currently in place with entities in the basin. Since the
implementation of the District/s water conservation plan in 2000/ followed by its update
