As seen from the production and sales graphs in the financial section of our packets, Elk
River is consuming large quantities of water. This year we will be close if not exceeding
our DNR appropriations of 875 million gallons. Attached is a letter dated 7-18-06 to
DNR Water with the pertinent attachments requesting the annual water appropriation be
raised to 1400 million gallons. This letter explains the reasons for the increase and our
conservation efforts to minimize water use.
The DNR also requires us to update water emergency and conservation plan which was
last revised in 2001. Staff is in the process of completing this document. This is a large
and time consuming effort with the end product of limited value.

Subject: Water Appropriation Increase
Dear Mr. Richter;
phone: 763.441.2020
Fax: 763.441.8099
Our current water appropriation permit # is 7~-3215. The quantity is limited to 6800 gpm and
87~ million gallons per year. llue to the growth in Elk River, we desire to increase our water
appropriation to 1400 million gallons per year, which will accommodate approximately 5 years
of growth. We are also studying the potential of adding an additional Mt. Simon Hinckley well
in 2007.
Enclosed is the following information for your review as justification to increase the annual
allocation:
1) Elk River Municipal Utilities water statistic graphs
a) Peak day pumpage graph from 1991 to projected 2015
b) Annual water pumpage from 1991 to projected 2015
Elk River continues to be a fast growing community. Currently there are
approximately 17 commercial/Industrial buildings under construction that are
not yet on the water system. A couple of these will be large water users in the area
of ~0 million gallons per year each.
2) Elk River Municipal Utilities water sales reports reflecting residential and
commercial/Industrial sales, revenue and number of water meters. The increase
in meter again reflects Elk River's fast growth rate.
3) Elk River Municipal Utilities water step rate analysis by residential and
commercial/Industrial rate class. These spreadsheets also reflect consumption
and number of customers. The residential average of off season usages per
meter (Nov, Dec, Jan, Feb & March) reflect a downward trend over time from
8.3 units/meter to 5 units/meter. The commercial/Industrial average of off
season usages stays relatively flat which is also good. Lawn sprinkling
continues to drive high usage in the summer months.
4) Elk River Municipal Utilities water conservation brochures, which includes lawn
sprinkling restrictions & door hanger.
We do several articles in our local paper concerning lawn sprinkling and general
water conservation.
5) In an effort to raise water conservation awareness, we have mailed to all water
customers the following:
a) 2005 -Moisture meter with a letter
b) 2006 -Rain gauges with a letter
Again our goal is to raise awareness about proper lawn sprinkling
practices.
6) Elk River Municipal Utilities water rate sheets. These rates reflect a 2 tier inclined
block rate structure with the higher second block designed to more effectively
discourage lawn sprinkling. Rates are adjusted on an annual basis. We are
experiencing many more high water bill complaints than previously which indicates
the rate structure is having a impact.
The above information shows our public education and conservation efforts are having some
success, but the growth of our community requires more water production capacity. As you
are aware, we are trying to do pilot test of an aquifer storage and recovery (ASR) system
utilizing our well #2. This pilot test has gotten Bela}red due to the EPA's request for additional
information. We plan to continue this pilot test but due to the delay we need to increase our
peak pumping capacity by drilling another well. Our schedule indicates this additional well
will happen in the 2007 time frame. As our plans become finalized, we will make application
for this additional well.
If you have any additional questions about the above, do not hesitate to call.
Bes regards,
pan Adams, P.E.

This graph reflects the peak day system usages the water production facilities must satisfy. Growth of the peak
day demand dictates when additional water wells, filter plants,and water towers must be added to the system.
Pumpage projections in the above graph are a function of both weather and growth.

This graph reflects the annual water use in Elk River. Water use of 651 million gallons is a
3.31 % decrease from 2003 due to unusual wet weather.
