ASPEN CREEK WATER COMPANY
OPERATIONS AND MAINTENANCE MANUAL
REGARDING SOUTH WELL CONSTRUCTION
AND NORTH WELL MODIFIACATIONS
INTRODUCTION
This manual is intended to be a supplement to the O&M manual for Aspen Creek Water
Company dated December of 2003. That manual details all of the construction of the existing
tank and all of the water lines. There is mention of the 91 lots to be developed on the south
side of Loveland Lane. Phase 1 of that development,Aspen Creek Meadows, has been
completed and built. The original plans for the overall water system stipulated that a second
source needs to be in place before approval of Phase 2. This manual and plans are in reference
to that second source.
This manual will detail all of the components of this new second source. Absent from this report
will be all of the data for the original Aspen Creek Water Company system for Aspen Creek
Estates. Please refer to that manual for that development.
This manual is intended to only provide an overview of the system and brief mention of problem
solving. If more thorough answers are need, it is recommended that the operator contact the
specialists directly. These may be, but are not limited to, Utah Power and Glenn's Electric.
OVERVIEW
The proposed pump and wellhouse are to be located approximately 1,200' south of the existing
well. The well will be constructed and owned by the Aspen Creek Water Company. The primary
function of this water company is to provide potable water to Aspen Creek Estates and Aspen
Creek Meadows.
The construction of this second well will be very close in execution to the original well. In fact,
the pump and motor for the existing well will be switched out to this new well house. In place
of that pump and motor, a new one will be installed.The pump will be upsized to account for a
greater water demand. The new pump will require a larger motor as well. A frequency drive
will be installed in the original well house to provide single-phase power to the new motor. This
eliminates having to run three-phase power to the site. This second source well will only
function when a low level is reached at the tank while the existing, updated pump is running.
The new pump will function solely as a backup working only if something should fail with the
current in-place system.
WELL PUMP,WELL HOUSE AND REVISED SYSTEMS
It is anticipated that the controls for the new pump house will be identical to those of the
existing well house. The main control will function in the same three modes, being auto, stop
and hand. This switch is to remain in the auto setting unless manual operation is desired. At
that point,the handle can be moved to hand and the start button engaged.

Other controls on the system inside the well house are as follow:
• Pump control switch
• Pump control valve
• Pressure gauge
• Shut off valve
• Circuit breaker and breaker box
• Warrick relay and telemetry probes
• Telemetry controls
The new well is anticipated to be drilled to a depth of 350'. This is taken from data provided
from the original well that is drilled to a depth of 350'. This proposed well will be fitted with the
current pump and motor in the existing well house. Please refer to the latest O&M manual for
specifications of this system. As a note,this system is running in a very efficient manner,
providing the needed water to the storage tank at a minimal cost. The water company has been
very pleased with the operation of this system. I have no doubt that this will be repeated in the
new well.
After the existing pump and motor are switched out of the existing well house, a new system
will be installed. The new pump will be a Goulds 150H25-10 pump that will provide 140 gallons
per minute at 540 feet of total dynamic head. The pump will be powered by a 25 horsepower,
230-volt motor. The manufacturer of this pump has not yet been determined. In order to
provide the power necessary, a frequency drive will be installed. This device has the ability to
provide 3-phase power from a single-phase source. This will eliminate the need for a new
power line to be run to the project and then the site. The existing 2" piping will be upgrade to
4" in the wellhouse. The existing PCV valve will remain to control the new pump on the existing
well. It will continue to function in its present manner. At his point in the manual, I will refer
you to the previous manual for instruction on pump failure, starting procedures and routine
maintenance schedules. This is contained in Appendix A.
The telemetry controls will be extended from the existing wellhouse to the proposed well
house. These controls will automatically turn on the proposed pump in the event that the
water level in the storage tank falls to 6 feet above the bottom of the tank. This elevation
coincides with the fire flow drawdown. Engineered models of the water system under fire flow
conditions resulted in water falling to a minimum depth of 7.02 feet above the bottom of the
tank. By positioning the telemetry controls below this level, it ensures that the second source
pump will only come on in abnormal conditions,when more water is needed. The existing
controls at 11 and 14.5 feet will continue to function in their current state.
A map has been included to show the proposed Phase 2 development of Aspen Creek Meadows.
Those plans are completed and have been reviewed by the local sewer and water board. They
have found the plans are in compliance with all local rules and regulations. This map will be
numbered with various nodes of importance. These relate to control valves,fire hydrants and
the proposed pump and well.

The fire hydrant maintenance will be exactly as stated in the RMES O&M manual. They should
be checked annually and flushed for several minutes. Turn the hydrant off slowly, meaning 1
minute per half turn. Failure to do so in this manner may result in transient waves in the system
that could rupture the pipes and cause cavitation to the valves.
If a break occurs in the waterline that requires the pump to be shut down and the system de-
pressurized, notification should be given to all of the affected residents in a timely manner. If at
all possible do not de-pressurize the entire line. Shut off sections of the pipe by using the valves
installed at tees in the system. If it is not evident which valves control what lines, please check
with the enclosed map or call this office for guidance. A copy of the water system should also
be on file with the local water board. Upon start-up after this situation, all state guidelines and
procedures must be followed exactly. This would include flushing and disinfecting the line and
testing a sample of the water for bacteria and other contaminants before the line is deemed in
service.
A schedule for testing for various contaminants and water quality is provided by the Department
of Environmental Quality. Element 6 of the TFM manual outlines when these tests are to be
completed. For additional information on testing procedures, contact the Idaho DEQ at 208-
236-6160.
In the event of a power outage, first contact Utah Power at 888-221-7070. The system is set to
return to normal operation once the power returns. In the auto mode there is no need to
manually start the system. This should be all that is needed for the majority of power outages.
If it appears that the power outage could last a considerable time, a portable generator should
be connected to the system. A hook-up for this purpose has been provided in the service panel
of the electrical box at the well house. Once the power is restored and the generator
disconnected,the system will function in its normal automatic mode.
If the pump has been left idle for an extended period of time, care should be taken at startup.
Samples should be taken at regular intervals during this time. If sand appears in the sample, do
not stop the pump. This common after long periods of pump inactivity. Continue pumping until
the sand is not present in the sample. This sample should then be testes at a certified lab and
results logged in a well maintenance book.
Information from the Operation and Maintenance manual for Aspen Creek Estates has been
supplied as Appendix A. This information contains site specific inspection checklists, meter
reading records, and hookup checklists. These are provided as a general plan and may be
modified as deemed necessary by the owner or operator of the Aspen Creek Water Company.
