2,0 Current Water Supplv

Broomfield currently supplies water to its residents from two sources 1)
Broomfield's Great Western Reservoir system and 2) a contract for treated
water from the Denver Water Department. Great Western Reservoir, the source
for about 60% of Broomfield's supply, stores water diverted from Clear Creek
and delivered to the reservoir through Church Ditch and Dry Creek Valley Ditch,
This ditch system delivers approximately 3500 acre-feet of water to Great
Western Reservoir annually (there are 326,000 gallons per acre-foot of water),
This water is treated at Broomfield's Water Treatment Plant, located on the
south west edge of town at 112th and Simms SI. The plant has a treatment
capacity of 8 million gallon per day (MGD), The Denver supply, approximately
40% of the supply, is purchased as treated water, and may originate from any of
Denver's three Water Treatment Plants, Broomfield's contract with Denver
allows for the purchase of up to 6500 acre-feet of water per year with a 2400
acre-feet minimum purchase requirement.

In general, the western area of Broomfield receives Broomfield water gravity fed
from the water storage tanks near Jefferson County Airport (6,95 million gallon
storage capacity), The eastern portion of the city typically gets Denver water
gravity fed from the 3,0 million gallon (MG) Carbon Road Water Storage Tank
(Figure 1). However, the deliveries may vary according to the availability of the
supply, or to accommodate maintenance projects, The City is able to supply the
entire system from either source, or to blend the sources, The water quality of
the two supplies is very comparable and meets all state and federal health
protection standards, A copy of the 1995 Annual Water Quality Report is
included as Appendix B,

2.1 Water and Wastewater Treatment Capacitv

The following Tables 1 and 2 give summaries of the production information for
Broomfield's Water Treatment Plant and the current demand on the system,
TablA ~ givAS similar rll'lta for thA Wl'lslewater Treatment Plant, The Table 1
data indicates that on average Broomfield's Water Treatment Plant is operating
at approximately 2,9 MGD or 37% of the 8 MGD capacity, The Denver system is
operating on average at approximately 2.2 MGD, The city's intergovernmental
agreement allows for the purchase of up to 13 MGD from Denver, The city wide
peak day for 1995 was 14,84 MG or approximately 71% of the combined
capacity (21 MG). The average day for 1995 was 5.18 (25% of total capacity)
The Wastewater Treatment Plant is operating at approximately 3.2 MGD or 59%
capacity, With the 1986 expansion at the wastewater treatment plant, the 8
MGD water treatment plant, and the ability to use up to 13 MGD in the Denver
Contract, the city can accommodate the current and short term future demand,
The effect of growth on the city's peak day water demand is a factor that must be
addressed in the future,
