Subject: Construction of Well #8
The 2003 budget contains a line item to construct Water Well #8. The remaining portion
of this project, filter plant modification and new water lines, will be started late this year
and completed in Spring 2004. The estimated cost of this total project is as follows:
Engineering $ 121,500
Test Wells (Well 8 & 9) 30,000
Production Well 250,000
Filter Plant Modifications 150,000
Raw Water Line 342,000
Well Site Work& Access Road 60,000
Total Project $953,000
Staff recommends authorization to proceed with this project and water revenue bonds be
sold to finance this project.
The need to construct this facility is based upon the following attached information.
a) City map reflecting the location of the new Well #8, new water line, and
filter plant #7 location. This map also reflects the proposed location of
possible future wells.
b) Graph reflecting Elk River water consumption characteristics.
We currently have six water production facilities with a peak pumping capacity of 7.92
million gallons per day (MGD) with all facilities operational, or 6.48 MGD with the
largest facility not operational at peak time. In 2001 which was a dry year, our peak day
was 5.32 MGD. Depending upon weather, our peak day in 2004 will approach 6.48
MGD. With current water consumption trends in Elk River, a water production facility
will accommodate approximately 700 residential homes. We have approximately 1500
available lots in Elk River with 200 to 300 meters being added annually. If this rate
continues, we will be adding a water production facility on a two to three year interval.
The enclosed map shows the location of the proposed facility along with future water
production facilities. Water production facilities 8 & 9 will be peaking facilities where
the facility is utilized only during peak times with minimal water treatment, (fluoride,
chlorine, no iron and manganese removal). A full water production facility with iron and
manganese removal will cost in the area of$1,500,000.

This graph reflects the peak day system usage 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.
The pumpage projections reflected in the above graph is a function of both Elk Rivers growth and weather.
Daily water requirements vary from 1 million to 5.3 million gallons/day.

This graph reflects the annual water use in Elk River. Water usage of 632 million gallons in the year 2002
is a 2.2%decrease from the previous year.
632 million gallons is equivalent to a 152 acre lake 13 feet deep which is similar to Lake Mitchell in Big Lake,MN.
