CHAPTER 3

WATER DEMAND AND WASTEWATER FLOWS

Water and wastewater facilities must be planned for, sized, and developed to ensure
continuous reliable service for average day, peak day, and peak hour conditions. In turn, water
demand and wastewater flow projections require an accurate population and user database and
an understanding of the criteria that affect demand. These criteria include:

· Climate conditions
· . Weather patterns
· . Historic user habits
· Water rates
· Community demographics
· Population
· Water conservation impacts

This chapter describes historical water demand and wastewater flows. Revised water and
wastewater projections are proposed based on historical data and increased growth rates at
Highlands Ranch. This chapter also suggests considerations for acquiring data for anticipated
updates to these projections.

Service Area Characteristics

Housing densities in Highlands Ranch are less concentrated than typical urban areas but
are more compact than unincorporated county developments. Development in Highlands Ranch
blends features of a fully-planned community with the ambience of a rural setting, enhanced by
open spaces, trail systems, parks, and geographical features.

At build-out, approximately 8,530 acres of residential and non-residential development
will be buffered by about 3,200 acres of schools, parks, and bike paths and 9,700 acres of
dedicated open space. The total population of Highlands Ranch is expected to range from
90,000 to 110,000. Plans also include up to 9,500 taps to be served within an extended service
area (ESA) composed of lands near Highlands Ranch.

The Highlands Ranch service area is composed of 5 districts, Metropolitan (Metro)
Districts 1 through 5. As of September 1992, Metro District 1 serves 3,758 residential service
taps, 132 commercial taps, and 19 irrigation taps. Metro District 2 serves 3,463 residential taps,
63 commercial taps, and 26 irrigation taps. Metro Districts 3, 4, and 5 currently do not have
residents within their boundaries. The residential portion of total water consumption is
approximately 64 percent, the commercial/industrial share approximately 26 percent, and
irrigation about 10 percent based on October 1991 through September 1992 water usage data
from the District's Finance and Administration Department.
