Chlorine Dosage Calculations
Calculations assume that the pounds of chlorine needed to achieve the target residual is the same. The chlorine metering pump has
an operating range that will allow flexibility to adjust the dose if needed. The new continuous chlorine analyzer will provide real time
residual chlorine concentration to inform dosing.
Historical Chlorine Dosing
Gaseous chlorine usage 900 lb/year Ponderosa site uses six 150 lb tanks/year
Based on yearly averages of 2020 and 2021 from
Average total annual irrigation 3.06 MG/year NDMRs
Average chlorine concentration dosed 36.1 mg/L
Conversion to Sodium Hypochlorite
Sodium hypochlorite dose is calculated to achieve
Sodium hypochlorite concentration req'd equivalent chlorine concentration to historical
in wastewater 75.7 mg/L gaseous chlorine dosing
Average weekly irrigation 0.06 MG/discharge event Irrigation typically occurs once per week
Sodium Hypochlorite concentration in
solution 12.5%
Req'd sodium hypochlorite solution
dosage 297 lb/discharge event
Based on a density of 1.16 g/cm3. A 330 gallon tote
Volume of sodium hypochlorite per will have sufficient volume for approximately 10
discharge event I 30.7 gal/discharge event Idischarge events, or 10 weeks.
Anticipated Dosing Rate
Duration of discharge event 9 hours
Hourly Chlorine Dosage 3.41 gal/hour
A 330 gallon tote will be refilled approximately 5
Annual Sodium Hypochlorite Usage 1,596 gal/year times per year
Selected Chlorine Pump
Minimum Pumping Rate I 0.004 gal/hr I Per 433383 in Specifications
Maximum Pumping Rate I 4 gal/hr

2. Use tapping machine compatible with valve and tapping sleeve;cut hole in main. Remove
tapping machine and connect piping.
D. Install piping by tunneling or jacking,or combination of both,under streets and other obstructions
that cannot be disturbed.
E. Install underground piping with restrained joints at horizontal and vertical changes in direction.
Use restrained joint piping,thrust blocks, anchors,tie rods and clamps.
F. Equipment Pipe Connections - Care shall be taken in bolting flanged joints, so that there is no
restraint on the opposite end of the pipe or the fitting which would prevent uniform gasket
pressure at the connection or would cause unnecessary stresses in the equipment flange. Bell and
spigot joints shall only be yarned or otherwise packed until all flange joints affected thereby shall
have been hand tightened without strain. Bolts shall be tightened gradually at a uniform rate and
in a program that will result in uniform gasket compression over the entire area of the joint.
Special care shall be taken when attaching suction and discharge piping to pumping equipment
so that no stresses are transmitted to or imposed on the pump. All pumping connection to pumps
or other equipment shall be so installed and so supported that accurate matching of the bolt holes
and uniform contact over the entire area of abutting pump or equipment flange and connecting
pipe line flange is obtained prior to the installation of any bolt in any flange. In addition, the
pump connecting or equipment piping shall be free to move in all directions parallel to its
longitudinal centerline when and while the bolts in the pump connection flange are tightened.
Pumps or equipment shall not be grouted prior to the initial fitting and alignment of the pipes
connected thereto. They shall, however, in each case be level, aligned and wedged in place in
position. The pumps or equipment shall be grouted prior to the final bolting of the connecting
piping in accordance with the provision of this paragraph. To provide the maximum flexibility
and ease of alignment, the pump or equipment connecting piping shall be assembled with the
gaskets in place with only a portion of the flange bolts, not less than four per joint, installed and
with the bell and spigot joints yarned but not leaded. After aligning and bolting, the pump or
equipment connection shall be tested by loosening the flange bolts, if the piping is properly
installed, there should be no change in the relationship of the piping flange to the pump or
equipment connecting flange.
G. Lining Up Bell and Spigot Pipe - Pipe lines or runs intended to be straight shall be so laid.
Deflections from a straight line or grade,made necessary by vertical curves or horizontal curves
or offsets,shall not exceed that recommended by the manufacturer of the pipe or approved by the
Engineer. If the specified or required alignment requires deflections in excess of those stipulated
above,the Contractor shall provide either special bends as approved by the Engineer, or pipes in
shorter lengths in such length and number that the annular deflections at any joint,as required by
the specified maximum deflections, are not exceeded.

cleaning, the joint gasket or rubber ring, if used, shall be placed on the pipe spigot as
recommended by coverage, supports, and such additional pertinent data as will be required by
future contractors for the replacement of any buried facility.
Where conditions are, in the opinion of the Owner's Representative,unsuitable for laying pipe
because of weather or trench conditions,the Contractor shall be required to cease work until
permission is given by the Owner's Representative for work to commence again providing such
conditions have been corrected.
1. Only proper and suitable tools and appliances for the safe and convenient handling and
laying of pipes and fittings shall be used. Pipe, fittings, and valves shall be carefully
handled and lowered into the trench. Under no circumstances shall any pipe or fittings be
dumped or rolled into trench or be allowed to drop against the pipe or fitting already in the
trench. Great care shall be taken to prevent the pipe lining and coating from being
damaged,and any lining or coating damaged in any way shall be repaired by the Contractor
to the satisfaction of the Engineer. Before being lowered and while suspended, the pipe
shall be inspected for defects and ductile iron pipe rung with a light hammer to detect
cracks. Defective, damaged or unsound pipe will be rejected.
2. The interior of the pipe shall be thoroughly cleaned of all foreign matter before being
lowered into the trench and shall be kept clean during laying operations by means of plugs
or other approved methods. The pipe shall not be laid in water or when the trench or
weather conditions are unsuitable for such work. When work is not in progress,open ends
of pipe and fittings shall be closed securely so that no trench water, earth, or other
substances will enter the pipe or fittings.
3. The full length of each section of underground pipe shall rest solidly upon the pipe bed,
and any defects due to settlement shall be made good by the Contractor at his own expense.
The ends of pipe shall abut against each other in such manner that there shall be no shoulder

approved by the Engineer or shorter lengths of pipe to provide angular
deflections within acceptable limits shall be furnished.
4) Alternate methods of jointing pipe will be considered by the Engineer if the
Contractor furnishes satisfactory evidence that the proposed alternate method
has been used successfully and is acceptable to the manufacturer of the pipe
and agreed to by the Owner.
8. Pipe excavation shall be kept free from water and no joint shall be made under water. The
Contractor shall be careful during backfilling to prevent damage to or disturbing of joints
and to protect the watertight integrity of the pipes at all times. There shall be no walking
on or working over pipe until backfill is over pipe. Backfilling shall be commenced by
depositing and tamping earth layers not more than 4 inches thick around and over the pipe
to a point not less than 1 foot in depth over the top,after which backfilling of the remainder
of the trench may proceed.

3.10 TESTING,INSPECTIONS AND DOCUMENTATION
A. Examinations and Testing of Pipe and Fittings
1. Examinations, testing and acceptance criteria, for manufactured pipe and fittings shall be
in accordance with the applicable AWWA or ASTM standards and pipe and fitting
manufacturer's instructions and recommendations. These include material tests for melt
index,density and%carbon, dimensional checks, examination for visual defects,and ring
tensile strength of piping. The results of all material and strength tests shall be available
for review by the Purchaser.
3.11 HYDROSTATIC TESTING
A. General
1. The Contractor shall be required to perform leakage tests on newly constructed mains as
outlined herein. The Contractor shall furnish the gauges,pump,pipe, connections and all
other necessary apparatus, and shall furnish the necessary assistance to conduct the tests.
The Owner or Engineer shall approve the gauges and measuring device used in the tests.
2. Leakage tests shall be performed on sections of line as indicated on the drawings. Testing
shall be conducted as the work progresses unless otherwise directed.
3. The Contractor may, for his benefit,perform the pressure tests and initial leakage test with
pipe joints left exposed and pipe sections backfilled one foot over the pipe as specified
under the Earthwork Section of this specification. Testing at that time will be permitted,
provided that sufficient time is allowed for miscellaneous concrete in the trench to develop
adequate strength prior to testing and trenches left open during this period do not constitute
a nuisance or hazard to the public. However,the pressure and leakage tests required in this
specification shall not be performed until final backfill and compaction has been
completed.
4. All testing for record shall be performed in the presence of the Owner or their Engineer or
his representative.
B. Test Procedures
1. Where any section of a main is provided with concrete thrust blocking or encasement,
hydrostatic testing shall not be performed until at least five days have elapsed after the
concrete was installed. If high-early strength cement is used in the concrete for thrust
blocks and encasement, the hydrostatic tests shall not be performed until at least one day
has elapsed unless otherwise directed by the Owner or their Engineer.
2. After completion of preparation and after test connections are made in a manner
satisfactory to the Owner or their Engineer,each section of pipe shall be slowly filled with
water and pressurized. All pressure shall be based on the elevation of the lowest points in
the test section and corrected to the elevation of the test gauge.
3. All air shall be expelled from the pipe. If permanent air vents are not located at all high
points, the Contractor shall install corporation cocks at such points so the air can be
expelled as the line is filled with water. After all air has been expelled, the corporation
cocks shall be closed and testing begun.
C. Leakage Test
1. After all air has been expelled from a test section, all connections made and other
preparations completed, the test section shall be subjected to leakage test pressure. This
test pressure shall be sustained by a pump,and the quantity of water delivered to the system
by the pump for a specified duration of time, shall be measured. At the end of the
FACILITY PROCESS PIPING 333400 - 18
PONDEROSA BUILDING AND DISINFECTION SYSTEM 5/5/2023

DocuSign Envelope ID:09475CD2-A468-4DA8-A895-34787ACC1636
designated time period,the quantity of water delivered to the test section shall be equal to
or less than the allowable leakage computed for the test section.
2. If any test of the pipe disclosed leakage greater than that specified, the Contractor at his
own expense shall locate and repair defective joints and/or material until the leakage is
within the specified allowance.
3. The Owner shall be furnished a written report of the results of the leakage test that identifies
the specific length of pipe tested, the pressure, and the duration of these tests,the amount
of actual leakage,and the leakage allowance. The report shall be signed by the Contractor
and the Owner or their Engineer.
D. Hydrostatic Test Pressure,Duration and Allowance for Pressure Mains
1. Pressure and leakage test:
a. The design working pressure (P) shall be calculated for the lowest point in a test
section using the following equation:
Design Working Pressure (P) PSI = (Design Pressure Elevation (ft) — Elevation at
Point(ft)0.4333 PSI/ft
Design Pressure Elevation=499 Ft(for potable water)
Design Pressure Elevation for Pumping = the pump shut off head in feet plus the
suction water level elevation(ft)time 0.433 PSI/ft
Test pressure shall be performed at 1.5 times the design working pressure with the
following expectations:
1) Test pressure shall not exceed pipe or thrust-restraint design pressure.
2) Test pressure shall not cause the working pressure of any valve or other
appurtenance to be exceeded.
3) Test pressure shall not exceed 150 psi along the test section.
b. The duration of the acceptable pressure and leakage tests is two hours for potable
water mains and thirty minutes for wastewater force mains. The test pressure shall
not vary by more than+/-5 PSI for the duration of the test.
C. Once the Contractor has filled the water lines and air has been expelled, the
Contractor shall pump water into the water line until the specified test pressure is
met. Leakage shall be defined as the quantity of water that must be supplied into
the newly laid pipe on any valved section thereof to maintain the specified test
pressure. Water line pressure shall be maintained within 5 PSI of the specified test
pressure during the duration of the test. If the pressure drops below the allowable
range, the Contractor shall inject water into the test section until the specified test
pressure is reset. The volume of water injected into the test section shall be
monitored and recorded in the presence of the Owner and his Engineer or
Representative. If the pressure does not drop below the specified range, no water
needs to be injected into the test section until the end of the test period. Again the
volume of water injected in the test section to obtain the specified test pressure shall
be monitored and recorded in the presence of the Owner or hid Engineer or
Representative.
d. The allowable leakage for a test section shall be 11.65 gallons per day per mile of
pipe per inch of nominal diameter based on a pressure of 150 psi.
e. The allowable leakage is determined by the following formula:
L = SD4P
148,000
Where:
L=allowable leakage, in gallons per hour
S=length of pipe tested, in feet

D=nominal diameter of the pipe, in inches
P=average test pressure during the leakage tests,in pounds per square inch(gauge)
3.12 DISINFECTION PROCEDURE WHEN CUTTING INTO AN EXISTING POTABLE WATER
MAIN
A. The following procedures apply primarily when the existing mains are wholly or partially
dewatered. After the tee in has been completed, the existing main may be returned to service to
the completion of bacteriological testing in order to minimize the time customers are without
water.
1. Trench treatment: Liberal quantities of hypochlorite shall be applied to open trench areas
in order to lessen the danger of pollution. Tablets provide an advantage in this situation,
because they dissolve slowly and continue to release hypochlorite as water is pumped from
the excavation.
2. Swabbing with hypochlorite solution: The interior of pipe and fittings (particularly
coupling and sleeves) used in connection shall be swabbed or sprayed with a 1 percent
hypochlorite solution before they are installed.
3. Flushing: Thorough flushing is the most practical means of removing contamination
introduced during tie in. If valve and hydrant locations permit, flushing toward the new
pipe work is recommended. Flushing shall be performed as soon as the connection is
completed and shall continue until discolored water is eliminated.
4. Bacteriological samples following procedures in 3.8 shall be taken after connections are
completed to provide a record for determining the procedure's effectiveness.
3.13 IDENTIFICATION
A. Install continuous underground detectable warning tape during backfilling of trench for
underground PVC piping. Locate below finished grade, directly over piping. Underground
warning tapes are specified in Division 31 Section "Earth Moving."
