SECTION III
DESIGN CRITERIA

EXISTING AND PROJECTED WATER REQUIREMENTS

Population and water consumption forecasts were first presented in the 1977 Service Plan [1].
A total of 331 EQR with a peak day demand of 250 gallons/EaR was recommended for design
purposes. However, it was thought probable that the average daily water consumption, on an
annual basis, could remain below 200 gallons/EaR. Subsequent experience has confirmed
this.

According to District officials, an annual average daily use of 200 gallons per day per EaR was
used in the Augmentation Plan. This value was developed from early operating records derived
from a daily record of water consumption for separate parts of the subdivision using meter
readings and storage tank measurements. These records indicated the average consumption
for single-family dwelling was about 200 gallons per day, based on measurements taken on
weekends and holidays, when dwelling occupancy should have been at its highest. These
measurements did not vary too significantly from readings taken at other times, i.e. weekdays,
winter, etc. This was thought to be indicative of the relatively high number of permanent
residents then in the area.

Meter records of use have not been presented to MWE. Recently the District has advised that,
during the time when water is hauled from Longmont, the average monthly consumption per
residence is 2,000 gallons, or 66 gallons per day per EaR. When the situation retums to
normal, with the River running and no hauling required, this monthly consumption has averaged
about 3,000 gallons, or about 100 gallons per day per EQR. These are exceptional numbers
and typify the conservation mindedness of the Pinewood Springs community, which has
resulted in the overall reduction in per-capita demand noted above.

According to Pinewood Springs officials the District has regulations prohibiting outside use of
water such as irrigation and car washing. It appears this regulation is generally adhered to by
the residents, accounting for the low average water consumption per household.
