BACKGROU ND/J USTIFICATION:
The 2019 Utility budget scheduled funding for the exploration and identification of a new municipal well to
support the East Public Water System. The need for an additional water source is warranted as three of
the five wells connected to the system are production limited for water quality reasons. Production wells
are also taxed from irrigation demands; seeing summer peak flows exceeding six times the winter use. The
MN DNR Water Supply Planning recommends that water demands are met even with the loss of the
highest production well. The addition of a municipal well will ensure this supply structure is met for the
near future.
The proposed test well location is on the Otsego Elementary School property (School). The location was
chosen because of the proximity to municipal well 1 providing access to existing pipework and electrical.
The City contacted three well contractors, and received responses from two well contractors to drill
approximately three hundred fifty feet to the Mt. Simon aquifer. This aquifer has provided excellent
capacity and good water quality at the nearby Well #6, located at School Knoll Park. Although the proposed
location is anticipated to have similar water quality characteristics and capacity, an exploratory well is
necessary to verify these assumptions as well as to conduct water quality testing on samples taken from
the proposed location.

Staff is recommending Traut Companies complete a 6" test well using the dual rotary method for
$61,146.00. This method is expected to be less impactful to Well #1 located on the same property and
provide a higher test pumping rate benefiting water capacity and quality information. A deduction of
bollards and cement pad is recommended to reduce the cost to $59,771.00. The test well will be sealed
after successful data collection to support cost of sealing the well.
A grant from the Minnesota Department of Health will be sought to assist with the project as it supports
our Wellhead Protection Program's "Data Collection — Implementation Action Item" which is a high priority
goal within the Plan.
The School District is verbally supportive of the future well. A full agreement will be sought to arrange
access for the exploratory well. Land acquisition will be sought if data supports a productive and quality
resource for a new public water supply well. Prior to initiation, the MN Department of Health will be
notified of the City's intentions allowing the agency to complete their review process.

G. Set 4" casing to the bottom of the 8 Inch Borehole.
H. Grout Casing in place with neat cement.
I. Drill 4" Open hole to the bottom of the Mt. Simon Aquifer.
J. Develop the well to provide clean groundwater.
K. Test pump.
L. Disinfect the well.
At all times during the progress of the work, the Contractor shall protect the well effectively
against tampering and entrance of foreign matter with a suitable cap or cover. The
Contractor shall also be responsible for any environmental damages to the ground surface
to include spillage of any hydraulic fluids, diesel or any petroleum products into the subsoil
from the drilling operations. Any damages shall be corrected by and at the expense of the
Contractor.
Well Development
The contractor shall provide all necessary labor and equipment to develop the open hole
portion of the well using air lifting, surging, and decompression methods. Development shall
be continued until the well produces the maximum practical yield of sand -free groundwater.
Water from development and test pumping shall be piped away from the well so it does not
cause unwanted disturbance, as determined by the Owner.
Test Pumping-
Upon
umping
Upon completion of well development, the Contractor shall furnish, install and remove his
own submersible pump and generator with sufficient lift and capacity to deliver a flow rate
of 30 gallons per minute at the wellhead. Failure to utilize an adequate pump to create this
flow will cause rejection of the test pump period until a pump of sufficient capacity is installed.
Any electrical service necessary to operate the Contractor's test pump shall be provided by
and at the Contractor's expense with no additional cost to the Owner.
Water Quality Sample
No water analysis to be performed.
Otsego Fest Well Near #1 - 10/16/18 5
Disinfection
After all test procedures have been made the well shall be disinfected in accordance with.
procedure(s) recommended by the MDH.
Abandonment of the Well
In the event that the Contractor fails to drill the Well in compliance with the Well Code or
must abandon the well because of loss of tools; the Contractor shall seal the abandoned
hole with neat cement grout. Materials and labor committed to construction of the failed well
and sealing of the well shall be at the Contractor's own expense. The Contractor may
attempt to salvage any materials used in construction of the failed attempt and those
materials shall remain the Contractor's property.
Gamma Log
If required, the Contractor shall perform a gamma log for determination of the formations of
the test hole to assure compliance with the Minnesota Dept. of Health Well Rules. Based
on the gamma log report, recommendations from the contractor shall be provided to the
Owner with regard to the final depth of the casing and open hole.
Clean-up
All areas disturbed by the contractor shall be restored to a rough grade condition. The
contractor shall remove all debris generated by the construction of the well including drill
cuttings.

PAYMENTS AND CONDITIONS
Invoices will be submitted at the end of each month for work completed and approved by
the Owner. Payment will be made within 30 days of the invoice less 5% retainage.
Retainage shall be paid after completion and acceptance of the project, meeting all terms
and conditions of the specifications.
While an attempt has been made to predict the geologic conditions (below the ground
surface) at the drilling site, the potential exists that unanticipated conditions may be
encountered. Additional materials, labor, and equipment required to accommodate
unanticipated conditions will be cause for changes to the contract price.
The total number of units in the Bid Schedule are estimates only and are subject to increase
or decrease based on actual geologic conditions.
The quantity and quality of water produced by a well is dependent on conditions and
