1. INTRODUCTION
1.1. Background
A new well has recently been completed for the City of Meridian Parks and
Recreation Department at the future 77 -acre park. When the park is complete, the
well will provide supplemental groundwater to irrigate the park when surface water
from the New York Irrigation District is not available or is insufficient to adequately
irrigate the park. Prior to park development, the well will be used for agricultural
irrigation. The site is currently being used to grow corn.
This Well Completion Report provides a summary of construction and testing for the
park well and also recommends a pump to meet the irrigation needs at the park. The
Well Completion Report includes an as -built well schematic, well driller's report, test
pumping data, and other pertinent data.
1.2. Site Location and Ownership
The 77 -acre park property is located south of Lake Hazel Road between Eagle Road
and Locust Grove Road in Ada County. The new well is located in the NE '/4 of the
NW '/4 of Section 5, T2N R1 E. The property is owned by the City of Meridian.
1.3. Water Rights
The City of Meridian owns two groundwater rights (license 63-33318 and permit 63-
33320) appurtenant to the park property. License 63-33318 authorizes a total
diversion of 0.78 cfs (350 gpm) from a single point of diversion located in the NW '/4
of the NE '/4 of Section 5, T2N R1 E. A water right transfer has been approved to add
the new well as an additional point of diversion, located in the NE '/4 of the NW '/4 of
Section 5. A copy of the transfer is provided in Attachment A.
Permit 63-33320 authorizes a total diversion of 0.76 cfs (341 gpm) from two points of
diversion, one in the NW'/4 of the NE'/4 of Section 5 and one in the NE'/4 of the NW
'/4 of Section 5. The new well can be used without modification to permit 63-33320.
The approved transfer associated with license 63-33318 allows the City to divert
water from the new well under both of the City's water rights with a total pumping
capacity of 1.54 cfs (691 gpm).
2. WELL DRILLING AND CONSTRUCTION
2.1. Introduction
The selected well drilling contractor was Stevens and Sons Well Drilling. Well
construction began in June 2014 and was completed in July 2014. The well was
constructed using the mud rotary method of drilling. The well location was surveyed
by the City prior to well construction.
SPF Water Engineering, LLC Page 1 8/6/2014
2.2. Borehole Drilling
As the first step in the well construction process, a nominal 10 -inch borehole was
drilled to a depth of 80 feet. Gravel and boulders were encountered to a depth of 24
feet. The 10 -inch hole was reamed to 17 -inch diameter to a depth of 26 feet, and 16 -
inch temporary surface casing was installed to 26 feet to stabilize the hole. Then a
nominal 15 -inch (14.75 -inch bit) borehole was drilled to the completion depth of 425
feet.
During drilling of the borehole, drill cutting samples were collected at each material
change and at approximate 5 -foot intervals. The borehole encountered non -water
bearing cemented sand, sandy clay, and a white sand layer to a depth of 140 feet.
Sand was also observed to a depth of 304 feet, with cemented sand between 170
and 250 feet. A thin clay layers was found between 304 and 306 feet. Between 306
and 418 feet, sand was encountered, with cemented zones between 326 and 346
feet and between 412 and 418 feet. From 418 to 425 feet, blue clay was found.
2.3. Geophysical Logging
After completion of the borehole, geophysical logging of the hole was conducted to
assist in evaluating suitable water -bearing zones to target. The geophysical log
included 8-, 16-, 32-, and 64 -inch normal resistivity, natural gamma, self -potential,
single point resistivity, temperature, and conductivity. A copy of the geophysical log
is included as Attachment B.
2.4. Well Construction
Upon review of the drill cuttings and geophysical log, it was determined that a sand
layer occurring between 346 and 412 feet below ground surface would be targeted
for well screen placement for the irrigation well.
The well was completed with 10 -inch mild steel casing (0.365 -inch wall thickness) to
a depth of 32 feet and PVC casing (SDR17) from 32 feet to 332 feet. Stainless steel
well screen with 0.030 -inch slots was placed between 332 and 412 feet.
A Colorado Silica Sand No. 8-12 filter pack was placed opposite the screen between
a depth of 295 and 424 feet. The surface seal consisted of a cement/bentonite grout
mix installed from the top of the filter pack at a depth of 295 feet up to 29 feet and
bentonite chips installed from a depth of 29 feet up to ground surface.
An as -built well construction schematic and driller's report are provided as
Attachment C.
3. DEVELOPMENT AND TEST PUMPING
3.1. Well Development
The well was developed by surging with the test pump until the water produced was
clear and there was no visible sand production.
SPF Water Engineering, LLC Page 2 8/6/2014
3.2. Test Pumping
3.2.1. Introduction
Well test pumping consisted of a step -rate test and a constant -rate test. Water levels
were measured with an electric -line well sounder. The test pump installed for the
test pumping was a 75 -hp submersible (Berkeley 8T600) supplied by Stevens and
Sons Well Drilling. The pump was set at a depth of approximately 275 feet below
ground surface. Flow rates were measured with a flow meter.
3.2.2. Step -Rate Test
The step -rate pumping test was conducted on August 4, 2014 and consisted of three
30 -minute steps. Flow rates were approximately 250 gpm, 500 gpm, and 700 gpm.
Jason Thompson, P.E. with SPF Water Engineering (SPF) observed the step -rate
test and measured water levels with an electric -line well sounder.
Static water level at the beginning of the test was 125.60 feet below the
measurement point (2.2 feet above ground surface). The pumping water level at the
end of the first step at 250 gpm was 137.28 feet below the measurement point, equal
to a drawdown of 11.68 feet. The pumping water level at the end of the second step
at 500 gpm was 149.32 feet below the measurement point, equal to a drawdown of
23.72 feet. The pumping water level at the end of the third step at 700 gpm was
159.92 feet below the measurement point, equal to a drawdown of 34.32 feet.
The specific capacity at each flow rate is summarized in Table 1. Specific capacity
did not vary considerably at different pumping rates, suggesting that the well is
relatively efficient over the tested discharge range.
Attachment D includes a summary of the step -rate test field data and graphs.

3.2.3. Constant -Rate Test
The constant -rate test was conducted on August 4, 2014, and consisted of pumping
the well at 700 gpm for 6.5 hours. Jason Thompson, P.E. with SPF observed the
beginning and end of the constant -rate test and measured water levels with an
electric -line well sounder and verified flow rate. Attachment D includes the constant -
rate test field data and graphs.
SPF Water Engineering, LLC Page 3 8/6/2014
The constant -rate test occurred immediately following the step -rate test. Pumping
water level at the beginning of the constant -rate test (end of step -rate test) was
159.92 feet below the top of the casing. At the end of the constant -rate test, the
pumping water level was 162.24 feet below the top of casing. Total drawdown at the
end of the constant -rate test was 36.64 feet, equal to a specific capacity of 19.1
gpm/ft over the duration of the constant -rate test.
Once the constant -rate test ended, water level recovery was measured for 30
minutes. Water level recovered to 128.26 feet, equal to 2.66 feet below the static
water level measured before the test pumping began.
Analysis of water -level responses for the drawdown and recovery portions portion of
the constant -rate test indicates an aquifer transmissivity ranging from 50,000 gpd per
foot to 70,000 gpd per foot.
3.2.4. Test Pumping Conclusions
For operating conditions where the pumping system is expected to continuously run
for a short period of time (hours) and then shutting down allowing for water level
recovery, a short-term specific capacity of approximately 18 gpm per foot of
drawdown is appropriate. This specific capacity was calculated by extrapolating the
constant -rate testing data out to 24 hours. Using a short-term specific capacity of 18
gpm per foot, the pumping water level is predicted to be 164 feet below the top of
casing at the design flow rate of 700 gpm. A plot of the extrapolated drawdown data
is included as Attachment D.
For operating conditions where the pumping system is expected to continuously run
for an extended period of time (on the scale of weeks or months), then a long-term
specific capacity of 15 gpm per foot of drawdown is more applicable. This specific
capacity was calculated by extrapolating the constant -rate testing data out to 6
months. Using this long-term specific capacity, the pumping water level is predicted
to be 172 feet below the top of casing at the design flow rate of 700 gpm. A plot of
the extrapolated drawdown data is included as Attachment D.
3.2.5. Sand Production
During the constant -rate test, sand content was measured on two separate
occasions using an Imhoff Cone. During both sampling events, only a trace amount
(a few grains) of sand was collected, indicating that the well does not produce
measurable sand.
4. WELL CONSTRUCTION AND TESTING SUMMARY
4.1. Well Construction
The park well was constructed to target a sand aquifer zone between a depth of 346
and 412 feet. The well is constructed with 10 -inch steel casing to 32 feet and 10 -
inch PVC casing from 32 feet to 332 feet. Stainless steel well screen was placed
from 332 to 412 feet. A silica sand filter pack was installed opposite and above the
screen. The well was sealed from the top of the filter pack at a depth of 295 feet to
SPF Water Engineering, LLC Page 4 8/6/2014
ground surface with cement/bentonite grout and bentonite chips. The surface seal
as installed in this well should be adequate to prevent any surface contamination
from reaching the developed aquifer zone.
4.2. Well Capacity and Pump Design
Test pumping of the park well demonstrates that the well can produce the target
pumping rate of 700 gpm with a long-term pumping water level of approximately 172
feet below the top of casing.
A pump was selected for the park well to deliver the maximum diversion rate of 700
gpm allowed by the City's appurtenant water rights. Pump selection assumes open
discharge delivery to two existing irrigation ditches, with the farthest delivery point
located about 2,000 feet from the well. A survey was not performed to identify the
elevations of the delivery points. However, the site is fairly flat and the elevation
differences between the well and delivery points are not considered significant.
When the site is developed into the park, the well will be used to deliver groundwater
to a pond to supplement surface water supply. Pump design assumes that the
elevation of this future pond will not be significantly different than the existing delivery
points.
Pump design for the park well includes a design flow rate of 700 gpm and a design
total dynamic head of 220 feet. The total head calculation includes a conservative
pumping water level of 172 feet, friction loss of 24 feet for 6 -inch column and
mechanical piping, and friction loss of 21 feet for approximately 2,000 feet of 8 -inch
HDPE discharge piping. The elevation difference between the well and the highest
delivery point is estimated to be 1 foot.
Given a flow rate of 700 gpm and a total head of 220 feet, a nominal 60 -hp
submersible pump will be required. An 8 -inch pump and motor can meet the design
requirements. The anticipated 10 -inch diameter SDR17 PVC well casing has an
inside diameter of 9.310 inches. This casing can accommodate the 8 -inch pump and
motor. The recommended pump is a Goulds 8FDLC, 3 stage, 4.8125 -inch impeller,
with a 3,600 rpm, 460 volt, 60 -hp submersible motor. A pump curve is provided as
Attachment E.
The submersible pump will be set on 6 -inch steel drop pipe, with a setting depth of
231 feet. The pump will discharge above -ground through a 90 degree elbow
installed on the top of the well casing. Well appurtenances, including an air -vacuum
valve, pressure gauge, check valve, winterization port, pressure relief valve, and
butterfly valve for throttling will be installed above grade near the well. A flow meter
is not currently anticipated, but a ductile iron spool of adequate length will be
provided to allow installation of a flow meter in the future. The pump will be
equipped with constant -speed motor controls installed in an outdoor -rated enclosure
near the well. At this time, the pump will be controlled manually. In the future, floats
could be installed in the pond to operate the well pump automatically off of pond
level.
