2.1 Water Supply Sources/Storage 'I'

Currently, the City provides service to approximately 20,000 people in addition to the businesses
of the City. Plant production in 1995 was approximately 3,300 Acre Feet or just over a Billion
Gallons, There are currently 5800 residential taps (as of December 1996) in the City system.
Projections for homes constructed in 1996 account for 260 Single family homes as well as 51
Multi-family units and 6 duplex units, In 1995,287 single family homes and 245 multi-family
with 10 duplex units were constructed. In 1994, 288 single family homes were constructed as
well as 32 multi-family units and 2 duplex units

Summer irrigation accounts for approximately 60 to 70 % of water demand, The lower number
of business and industrial accounts is the predominant reason why such a great amount of the
peak usage is irrigation water.

The Indian Peaks golf course, which was designed under the xeriscape concept, uses
approximately 500 AF per year. The golf course covers approximately 175 acres. Irrigation
requirements is estimated at an average of35 inches per year.

2.2 Water / Wastewater Treatment Capacity

Current capacity of the Baseline Water Treatment Plant is 8.0 MGD. In addition, we have an
agreement for 'up to 2.0 MGD of treatment with the City of Louisville, 'The agreement with
Louisville anticipates expansions to the Baseline Plant meeting the projected growth of the City.

The Waste Water Treatment Plant was recently expanded and has a capacity of2.8 MGD.

2.3 Conservation Measures.

1. Water - efficient fixtures

Plumbing Codes: The City code (Ordinance 30-180) requires all new construction to install 3.5
gallon per flush water closets. Three gallon per minute faucets, showerheads, and lavatories are
also specified. Additionally, all permitted work must meet the same standard (copy of ordinance
enclosed), Current products on the market haye lower use rates than mandated by code.

2. Low water-use landscapes and efficient irrigation

The City has no formal adopted policy or ordinance that addresses this practice. However,
during the design of any project, water requirements are evaluated and conservation measures are
encDuraged. An example of the implementation of such recommendations includes, but is not
limited to, the Indian Peaks 18 hole championship golf course which has installed xeriscape
