AUTHORIZATION TO CONSTRUCT NEW WELL
Applicant requests the Commissions authorization to construct a new well with the
capacity of approximately 2,200 gallons per minute. The Idaho Department of Environmental
Quality (DEQ) sent a letter dated July I 9,2016 (Exhibit I ) to applicant. In the letter, the DEQ
noted that in certain areas of Falls Water's service area (notably the Edwards Drive area) the
water pressure dropped below the required 40 psi minimum pressure required by the ldaho
Rules for Public Drinking Water Systems.
DEQ suggested that the corrective actions for this would be to restrict water usage (e.g.
day, time, duration) or to increase capacity through additional sources, storage, or pumping
capacity. Falls Water implemented odd-even watering days on July I ,2016 (Exhibit 2).
However, the watering day program was insufficient to correct the problem in the area affected
by the low pressure.
In 2013, Schiess & Associates modeled the requirements to add a Norco gas store to our
system. The fire flow requirements were for 2,000 gpm. If all of Falls Water's pumps were on
and a one mile loop was completed, the required fire flow could be achieved. If Well #9 was out
of commission, the system could not provide the required fire flow and system pressures would
drop to zero in some areas. As stated by the letter, "[t]his does not comply meet the drinking
water rules." (See Exhibit 3). Using the peak demand data for 2016, the system cannot meet fire
flows of 1,500 gpm (for residential fires) if Well #9 were out of commission. The production is
2.945 gpm short of demand plus a 1,500 gpm fire flow when Well #9 is not available. (See
Exhibit 4).
Applicant now seeks to correct the issue by constructing a new source well to increase
thepressureintheaffectedareasofFallsWater'ssystem. Thesitechosenisneartheaffected
subdivision and will improve pressures by providing the needed flow and pressure to that area of
the system.
Applicant seeks the Commission's acceptance of the well expendatures as rate base irr
future rate cases the Applicant will present.
It is estimated that the cost of the new well, well house, pumping equipment, and controls
will be$647,215(Exhibit5). Applicantproposesthatthecostsforthisprojectbeprovidedfrom
the "special plant reserve fund" created in Order No. 32663.
Falls Water requests that the application be considered by the ConTrnission under the
rules of Modified Procedure.
Applicant respectfully requests expeditious and favorable consideration of this
application

Re: Maintaining Minimum Pressure Requirements Throughout the Entire Distribution
System in Falls Water Company PWS# 7100030
Dear Mr. Wise,
In reviewing pressure data that was recently collected within the Falls Water Company water system, it
has been determined that some of the areas of the distribution system are falling below the minimum
pressure requirements set forth by the Department. The Idaho Rules for Public Drinking Water
Systems states the following:
o 58.01.08.548.01.b.v - Public water systems shall maintain a minimum pressure of forty (40)
psi throughout the distribution system, during peak hour demand conditions, excluding fire
flow, measured at the service connection or along the property line adjacent to the consumer's
premises.o 58.01.08.548.01.b.i - Any public water system shall be capable of providing sufficient water
during maximum day demand conditions, including fire flow where provided, to maintain a
rninimum pressure of twenty (20) psi throughout the distribution system, at ground level, as
measured at the service connection or along the property line adjacent to the consumer's
premises.
The recent pressure date (attached) taken on Thursday July 14s demonstrate that during the hours of
3am to 6am the pressure taken from the Edwards location dropped below 40 psi and to as low as 35
psi. It is not known if the system could maintain 20 psi at this location if there happened to be a fire
event.
The Falls Water Company is required to maintain 40 psi throughout the system and must take
corrective action to ensure minimum pressure is met. The corrective action could be to restrict water
usage (e.g. day, time, duration), which the system has already attempted to implement, or increase
capacity through additional sources, storage, or pumping capacity.

Dear Customer,
ln order to continue to provide efficient water service and water pressure to our customers, it is
necessary to implement a restriction for outside watering of lawns and landscaping. Starting July 1 ,2016
through September 30, 2016 outside water use will be limited to every other day as follows.
1. Homes that have even numbered street addresses may water lawns and landscapes on Monday,
Wednesday, and Friday.
2. Homes that have odd numbered street addresses may water lawns and landscapes on Tuesday,
Thursday, and Saturday.
3. Anyone may water outside on Sunday.
As you reset your sprinkler systems for the correct watering days, please look to see what trme your
sprinkler system starts. Our records indicate significant demand spikes about 10.00 pm and 1:00 am.
Please consider starting your sprinkler cycle a little earlier or later. By starting your sprinklers at a time other
than peak demands, you may see your sprinklers provide better coverage as water flow and pressures can
be better when demand is spread out.
lf you are a business, church, or school that waters lawns or landscapes with Falls Water Co.'s
system, it is requested that you water between the hours of 5:00 am and 7:00 pm so long as it does not
interfere with your business, ie. customers or patrons getting wet during business hours.
Anyone having newly seeded, hydro-seeded lawns, or sod requiring additional water may follow the
following schedule for the first 60 days after putting in the lawn:
1. Up to 3 times daily for the first 30 days.
2. One time per day for the second 30 day.
3. After the first 60 days, you must follow the watering schedule listed above for even or odd
num bered street addresses.
We ask that you adjust your watering schedules to assist in providing more efficient water service and
water pressure to you and to your neighbors. Thank you for your assistance in this effort.
Sincerely,
Falls Water Co., lnc.
