Rates for water sold or furnished to customers for use outside the City limits shall be one hundred ten percent (110%) the rates for water sold or furnished for use inside the City.

B.    Special Rates:

Special rates for customers who are not included in existing customer classifications and have usage characteristics different from other customers may be negotiated between the City and customer, without requiring an amendment to the City Code.

C.    Special Rates: If the initial bill of any new consumer or the final bill of any consumer shall show usage of less than one thousand (1,000) gallons for the initial or final billing period, the consumer shall be billed for the initial or final billing period at the prorated amount based on existing rates for each one hundred (100) gallons or fraction thereof.

Because fire hydrants are not designed to sustain continuous use and because such hydrants are part of the emergency fire protection system of the City, regular use of fire hydrants for water supply is discouraged. When an applicant for water to be delivered from a hydrant can show hardship if forced to obtain water from another source, and the request has been approved in writing by the City’s Utilities Director, the Division may install a meter on a fire hydrant for the use of such applicant, following payment of the required fee for such installation and use. The applicant shall be and remain responsible for payment to the City for all water used through such hydrant meter, and for the purpose of protecting himself may place a lock upon said meter.

The fee for installation and use of such hydrant meter shall be $110.00. The rate of water delivered through a hydrant meter shall be at existing standpipe rate. In addition, a seven hundred dollar ($700.00) deposit will be required to assure repair work on the meters and hydrants if needed. An additional three hundred dollar ($300.00) will be required when a backflow prevention device is necessary. The deposits will be refunded if there is no damage sustained when the meter and/or backflow device is returned to the City.

D.    Automatic Rate Adjustments. The City agrees to adopt a rate schedule which provides for automatic adjustments to pass along increases in energy related operating costs for delivering water service based on the current electrical and gas tariff rates on file with the Arizona Corporation Commission. Automatic adjustments to the energy surcharge shall be calculated on an annual basis using the past 12 months rolling average of water related energy charges.

1.    Energy Cost Adjustment. City reserves the right to automatically pass along future increases in electrical and natural gas energy related charges imposed on City by another agency. These automatic adjustments may be made whenever the other agency: (1) increases the standard cost of energy beyond the current energy cost assumed by City in the proposed rate structure described in this section.

2.    Adjustments shall begin on January 1 of each calendar year and continue through the end of year. (Ord. 1235, 11/29/82; Ord. 1681, 12/04/90; Ord. 1727, Amended, 12/03/91; Ord. 1796, Amended, 03/16/93; Ord. 1809, Amended, 06/15/93; Ord. 1825, Amended, 12/07/93; Ord. 1874, Amended, 06/20/95; Ord. 1944, Amended, 05/20/97; Ord. 1972, Amended, 04/21/98; Ord. 1999, Amended, 07/06/99; Ord. 2000-03, Amended, 03/07/00; Ord. 2002-05, Amended, 05/21/02; Ord. 2002-07, Amended, 07/16/02; Ord. 2006-27, Amended, 11/05/06; Ord. 2010-23, Amended, 09/07/10; Ord. 2016-23, Amended, 04/19/16)

Meters will be sized using the American Water Works Association Manual, AWWA No. M22. Sizing will be submitted to the City Utilities Department by the developer or owner for City review.

All capacity charges for connections larger than four inches (4") shall be based on proration of midrange flow gallons per minute (gpm) of a 5/8 x 3/4 inch meter divided into the midrange flow of the meter to be evaluated. The resulting number shall be used as a multiplier times the capacity fee for a 5/8 x 3/4 inch meter to determine the large meter capacity fee. Meters will be sized using American Water Works Association Manual, AWWA No. M22. Sizing will be submitted to the City by the developer or owner for City review.

Where the capacity charge is based on volume, said charge will initially be calculated based on an estimate of flowage agreed upon by the City and the customer and will be adjusted based upon the volume of the highest consecutive twelve (12) month period for the thirty-six (36) months immediately following commencement of service or assessment of an additional capacity charge.

When the capacity charge results from an increase in meter size the charge shall be adjusted to the difference between the charge for the new size meter and the charge for the previous size meter.

C.    The Division shall review all customer accounts with meters larger than four inches (4") on an annual basis and assess as additional capacity charge when the annual average demand increases by twenty percent (20%) or more. The additional capacity charge will be calculated using the recommended meter size by AWWA Manual No. M22 or equating to equivalent 5/8 x 3/4 inch meters but substituting for demand the difference between actual current demand, as determined by the previous twelve (12) month average, and the demand used to calculate the previous capacity charge assessed upon the customer.

1.    The Division shall maintain a list of approved backflow prevention assemblies, by type and manufacturer. Any consumer required by the Division to install an approved backflow prevention assembly must utilize an assembly included in such list.

2.    Backflow prevention assemblies shall have a diameter at least equal to the diameter of the service connection.

3.    Backflow prevention assemblies shall be installed and maintained by the customer, at the customer’s expense and in compliance with the standards and specifications adopted by the City of Flagstaff at each service connection. The customer is responsible for notifying the City of Flagstaff Industrial Waste Section of any installation, repair, relocation or replacement. A backflow prevention assembly shall be installed as close as practicable to the service connection outside the building unless it is for a fire line.

A waiver may be granted by the Industrial Waste Manager for the retrofit installation of a backflow prevention assembly inside the building provided a City of Flagstaff Attorney approved "Backflow Prevention Assembly Hold Harmless Agreement" is signed by the property owner and notarized. This document must be received and approved the City of Flagstaff Industrial Waste Manager prior to the installation of the backflow prevention assembly. RP’s for fire line assemblies may be installed inside a fire riser room provided they have an adequate drain for a full port discharge for the size of the assembly per the manufacturer’s specifications into the sanitary sewer system, not the storm water system. If a drain cannot be provided that can contain a full port discharge to the sanitary sewer system from a fire line with chemical additives such as anti-freeze or glycerin, the assembly must be installed outside the building in an insulated enclosure with electricity for a heat source for freeze protection and a check valve must be installed in the system to prevent the discharge of antifreeze onto the ground.

The assembly shall be in an accessible location approved by the Division and protected from freezing. The RP, RPDA, DC, DCDA, PVB and SVB shall be installed above ground and per City of Flagstaff standard details. Backflow prevention assemblies shall not be installed in a meter box, pit or vault.

A double check valve assembly may be installed, upon approval of the Division, below ground in a vault which meets standard specifications established by the City.

4.    When a customer requires a continuous water supply, two backflow prevention assemblies shall be installed parallel to one another at the service connection to allow a continuous water supply during testing, repair and/or maintenance of the backflow prevention assemblies. When backflow prevention assemblies are installed parallel to one another, the sum of the cross-sectional diameters of the assemblies shall be at least equal to the cross-sectional diameter of the service connection or service line piping at the point of installation and the assemblies shall be of the same type.

5.    For an AG installation all piping installed between the user’s connection and the receiving tank shall be entirely visible unless otherwise approved in writing by the City of Flagstaff Industrial Waste Section.

6.    It shall be unlawful for any person to bypass or remove a backflow prevention method without the approval of the Division.

7.    Any property with more than one water service connection shall install backflow prevention assemblies on each service connection to the property, unless otherwise designated by the Division.

8.    Fiberglass insulation cannot be wrapped or otherwise placed around a backflow prevention assembly as a form of freeze protection as it allows condensation to occur and subsequent degradation of the backflow prevention assembly. There must be adequate air flow around the backflow prevention assembly to prevent the formation of condensation on the assembly.

9.    All test cocks and relief ports on a backflow prevention assembly must be accessible for testing and for release of water from the relief port during a discharge event.

10.    A PVB or SVB assembly may be installed for use on a landscape water irrigation system if:

a.    The water use beyond the assembly is for irrigation purposes only.

b.    The PVB/SVB is installed in accordance with the manufacturer’s specifications.

c.    The irrigation system is designed and constructed to be incapable of inducing backpressure.

d.    Chemigation, an injection of chemical pesticides and fertilizers, is not used or provided for in the irrigation system.

e.    No other source of water is available on the premises.

f.    Single family residences with testable backflow prevention assemblies will not need to test the assemblies on the landscape irrigation assemblies each year. Condominiums and townhomes that are part of a Home Owners Association (HOA) do need to test the backflow prevention assemblies on the landscape irrigation system each year.

If the criteria are not met, then an RP assembly is required.

11.    No person shall alter, modify, bypass or remove a backflow prevention method without the approval of the City of Flagstaff Industrial Waste Section.

12.    Installation of the backflow prevention assembly must be completed within the time specified in the notice to install or within forty-five (45) days of the water meter installation. A time extension may be granted by the City of Flagstaff provided no cross-connection hazards exist at the site.

13.    If a customer fails to install a backflow prevention assembly pursuant to this article, the City of Flagstaff shall discontinue water service and assess a compliance fee pursuant to this article.

14.    All backflow prevention assemblies shall be installed with a y-strainer or fire line strainer unless the manufacturer states that the assembly cannot have one. The y-strainer or fire line strainer shall be installed directly upstream of the assembly.

15.    A backflow prevention assembly for containment or landscape may need to have a pressure reducing valve upstream of it if the water line pressure is higher than 80 psi. This does not apply to fire lines.

(Amended Ord. No. 2010-06, 04/20/10)

G.    Installation of Backflow Prevention Assemblies for Fire Systems

Fire Systems

1.    Fire protection systems may consist of sprinklers, hose connections, and hydrants for commercial, industrial or residential structures and services. Sprinkler systems may be dry or wet, open or closed. Systems consisting of fixed-spray nozzles may be used indoors or outdoors for protection of flammable-liquid and other hazardous processes. It is standard practice, especially in cities, to equip automatic sprinkler systems with fire department pumper connections.

2.    A meter (compound, detector check) should not normally be permitted as part of a backflow prevention assembly. An exception may be made if the meter and backflow prevention assembly are specifically designed for that purpose.

3.    For cross-connection control, fire protection systems shall be classified on the basis of water source and arrangement of supplies as follows:

a.    Class 1: Direct connections from public water mains only; no pumps, tanks or reservoirs; no physical connection from other water supplies; no antifreeze or other additives of any kind; all sprinkler drains discharging to atmosphere, dry wells or other safe outlets.

b.    Class 2: Same as class 1, except that booster pumps may be installed in the connections from the street mains. It is necessary to avoid drafting so much water that pressure in the water main is reduced below twenty (20) psi.

c.    Class 3: Direct connection from public water supply main plus one (1) or more of the following: elevated storage tanks; fire pumps taking suction from above-ground covered reservoirs or tanks; and pressure tanks (all storage facilities are filled or connected to public water only, the water in the tanks to be maintained in a potable condition). Otherwise, Class 3 systems are the same as class 1. Class 3 systems will generally require minimum protection (approved double check valves) to prevent stagnant waters from backflowing into the public potable water system.

d.    Class 4: Directly supplied from public mains similar to classes 1 and 2, and with an auxiliary water supply on or available to the premises; or an auxiliary supply may be located within seventeen hundred (1,700) feet of the pumper connection. Class 4 systems will normally require backflow protection at the service connection. The type (air gap or reduced pressure) will generally depend on the quality of the auxiliary supply.

e.    Class 5: Directly supplied from public mains, and interconnected with auxiliary supplies, such as: pumps taking suction from reservoirs exposed to contamination, or rivers and ponds; driven wells, mills or other industrial water systems; or where antifreeze or other additives are used. Classes 4 and 5 systems normally would need maximum protection (air gap or reduced pressure) to protect the public water system.

f.    Class 6: Combined industrial and fire protection systems supplied from the public water mains only, with or without gravity storage or pump suction tanks. Class 6 system protection would depend on the requirements of both industry and fire protection, and could only be determined by a survey of the premises.

g.    Installation of assembly

When a backflow assembly is required for a water service connection supplying water only to a fire system, the assembly shall be installed on the service line in compliance with standard specifications adopted by the city. (Installation of DC or DCDVA) may be allowed on fire systems with the City of Flagstaff approval provided both the manufacturer’s specifications and USC approval allow such an installation. If an RP is needed for a fire line system and the RP is inside a structure, that room must have a drain large enough to contain the full port discharge volume for that size of assembly with that areas water pressure. The drain must go to the sanitary sewer and not the storm sewer.

(Amended Ord. No. 2010-06, 04/20/10)

H.    Inspections

1.    A customer’s water system shall be available at all times during business operations for premises inspection and backflow prevention assembly testing by City of Flagstaff personnel. The inspection shall be conducted to determine whether any cross-connection or other hazard potentials exist and to determine compliance with this article and modifications.

2.    City of Flagstaff shall inspect all new sites, assembly installations, assembly relocations and assemblies that have been repaired for compliance.

3.    A waived premise is a property for which the City of Flagstaff has determined there are currently no hazard potentials. All waived premises shall be inspected periodically or when there has been a change in owner/tenant or there has been a use change.

4.    If a customer refuses entry to a premise for inspection during business operations, the City of Flagstaff may discontinue water service, require backflow prevention or take any steps allowed by law to gain entry to the premises.

(Amended Ord. No. 2010-06, 04/20/10)

I.    Permit

1.    Installation permits for the installation of all backflow prevention assemblies required by the City of Flagstaff shall be obtained from the City of Flagstaff prior to installation. A separate permit shall be obtained for each required backflow prevention assembly to be installed, including replacement or relocation.

2.    It shall be the duty of the person doing the work authorized by the permit to notify the City of Flagstaff, orally or in writing, that the work is ready for inspection. Such notification shall be given not less than twenty-four (24) hours before the work is to be inspected and shall be given only if there is reason to believe that the work done will meet current city codes and regulations.

3.    Whenever any work is being done contrary to the provisions of the city plumbing code or this article, the City of Flagstaff or an authorized representative may order the work stopped by notice in writing served on any persons engaged in the doing or causing such work to be done; and any such person shall forthwith stop such work until authorized by City of Flagstaff to proceed with the work.

4.    Any City of Flagstaff employee may, in writing, suspend or revoke a permit issued under provisions of this article, whenever the permit is issued in error or on the basis of incorrect information supplied, or in violation of any ordinance or regulation of any provision of the City Plumbing Code or this article.

(Amended Ord. No. 2010-06, 04/20/10)

J.    Maintenance and Testing

1.    The annual test compliance date shall be set by the City of Flagstaff Industrial Waste Section. The consumer shall have backflow prevention assemblies tested upon installation and at least once per year, or more frequently if deemed necessary by the Division, at the consumer’s expense. The customer shall arrange for repairs if the testing reveals the assembly to be defective or in unsatisfactory operating condition. If the testing reveals the assembly to be defective or in unsatisfactory operating condition, the customer shall arrange for repairs. The customer shall have performed, by an appropriately licensed contractor, any necessary repairs within 30 days or as directed by the Division, including replacement or overhaul of the assembly if necessary, which will return the assembly to satisfactory operating condition. The customer shall then have the assembly retested, within 30 days following repairs, until testing reveals no defects or unsatisfactory operating conditions. If the Division determines that a health hazard exists, they may specify a more restrictive repair schedule. All residences with fire line backflow prevention assemblies shall have the assemblies tested annually on the anniversary date. Single family residences with testable backflow prevention assemblies will not need to test the assemblies on the landscape irrigation assemblies each year. Condominiums and townhomes that are part of a Home Owners Association (HOA) do need to test the backflow prevention assemblies on the landscape irrigation system each year.

2.    The customer may request orally or in writing a change of the annual test compliance date for any assembly. No compliance date may be changed to be more than twelve (12) months after the most recent test.

3.    The consumer shall be responsible for maintenance of all backflow assemblies at his/her expense. If the Division or customer learns or discovers, during the interim period between tests that an assembly is defective or in unsatisfactory operating condition, the customer shall arrange for repairs. The customer shall have any necessary repairs performed by an appropriately licensed contractor, including replacement or overhaul of the assembly, if necessary, which will return the assembly to satisfactory operating condition within 30 days of discovery. Such assembly shall be retested within 30 days following repairs, until testing reveals no defects or unsatisfactory operating conditions.

4.    All testing shall be performed by an individual who holds a valid "General" Tester Certification issued by the California-Nevada American Water Works Association (Cal-Nev AWWA), the Arizona State Environmental Technical Training (ASETT) Center, or other certifying authority approved by the Division. A list of certified testers registered with the City of Flagstaff shall be maintained by the City of Flagstaff Industrial Waste Section and shall be available upon request to all persons required to install or maintain a backflow prevention assembly. Test procedures shall be performed as required by the ADEQ as set forth in Chapter Nine of the most current edition of the USC-FCCCHR Manual Cross-Connection Control. The tester shall provide a copy of the test report to the customer and to the City of Flagstaff Industrial Waste Section within five (5) working days from the date of the test and shall maintain a copy for their records for at least three years. If the tester fails to submit a test result within 5 days from the date of the test, their name shall be removed from the tester list.

5.    No existing backflow prevention assembly shall be altered, disconnected or replaced without prior approval of the Division.

6.    All backflow assemblies installed on fire sprinkler systems shall have a chain with a padlock from the first O.S. & Y. valve to the second O.S. & Y. valve, or an operable alarm system or both.

7.    Test cocks are to be used for testing only and shall be installed in accordance with Division requirements. Any unauthorized use of these test cocks is a violation of this code.

8.    Each backflow prevention assembly shall be easily identified by displaying the following in a conspicuous manner on the assembly:

a.    Manufacturer

b.    Model Number

c.    Serial Number

This information must also be provided to the Division by the consumer promptly upon installation.

9.    The customer shall maintain records, on forms approved by the City of Flagstaff, of the results of all tests and all servicing, repairs, or replacements of the backflow prevention assembly. A copy of the records shall be provided to the City of Flagstaff within five (5) days after completion of the activity for which the record is made.

10.    The consumer shall notify and receive approval from the City of Flagstaff Fire Marshall, at least 24 hours in advance, of any maintenance or testing performed upon assemblies installed upon fire sprinkler systems which requires discontinuance of water supply to that system. Fire systems shall not be out of service for more than eight (8) consecutive hours due to testing, maintenance or repairs. The fire department shall be notified immediately of any changes in fire service status.

11.    City of Flagstaff may test any backflow prevention assembly at any time.

12.    The City of Flagstaff will return incomplete and erroneous test forms to the tester and customer for correction and resubmission by the compliance date. Information on submitted test forms can only be changed or modified by the tester who has signed the form and is responsible for that test.

13.    Test equipment shall be maintained and calibrated annually by an agency approved by the City of Flagstaff as required by the cross connection manual. A copy of the annual equipment calibration certificates shall be submitted to the City of Flagstaff Industrial Waste Section to maintain equipment registration and certification. Test equipment for testing backflow prevention assemblies in the City of Flagstaff service area shall be registered with and approved by the City of Flagstaff. Test equipment used on anything other than potable water backflow prevention assemblies shall not be used to test such assemblies and shall be identified as non-potable test equipment.

14.    Testers shall register with the City of Flagstaff Industrial Waste Section if they are conducting backflow assembly testing in City of Flagstaff service area. Testers shall submit a current copy of their certification or recertification upon registration. Testers, upon renewal of tester certification, shall be certified on all backflow prevention assemblies that may be used for service protection. A City of Flagstaff registration issued to a backflow prevention assembly tester for testing backflow prevention assemblies in the City of Flagstaff service area may be revoked or suspended upon certification expiration or for improper testing, maintenance, reporting or other improper practices.

(Amended Ord. No. 2010-06, 04/20/10)

K.    General Penalty and Fees

1.    Violation of any section of this Ordinance shall constitute a misdemeanor and shall result in a fine of no less than one hundred dollars ($100.00) and not to exceed twenty-five hundred dollars ($2,500.00) for any one offense. A separate offense shall be committed for each day of noncompliance with any of the requirements of this Ordinance.

2.    When convicted of a violation of this Ordinance, any license previously issued to that person by the City may be revoked by the Flagstaff City Council or any proper court, if there may be reasonable relationship between the activities listed and the offense. Revocation of license shall not be considered a recovery of penalty so as to bar any other penalty being enforced.

3.    The Division may deny or discontinue, after reasonable notice to the occupants thereof, the water service to anyone using the City of Flagstaff water distribution system or to any premise wherein any backflow prevention assembly or method required by these regulations is not installed, tested, maintained and repaired in a manner acceptable to the Division, or if required reports and/or records are not properly filed, or if it is found that the backflow prevention assembly or method has been removed or bypassed, or if an unprotected cross-connection exists on the premises. Reasonable notice shall be sent in writing at least two weeks prior to the disconnection, unless the Division determines that a potential for a severe health hazard exists.

If the Division determines that a potential for a severe health hazard exists the Division may immediately discontinue water service without notice. Notice by telephone will be given as soon as possible and written notice will be sent within five (5) days, following discontinuance of water service.

7-03-001-0017 PURCHASED ENERGY COST FOR WATER

Whenever the City of Flagstaff’s purchased power (electric fuel and/or natural gas) expense in any of its water systems increases or decreases, or will increase or decrease, from the amount adopted by the City Council in the Utilities last general rate proceeding for that system, the Utility may adopt a new energy charge schedule designed to recover such increased or decreased purchase power expense, provided that:

A.    The total amount of the increase or decrease in purchased power expense will be calculated by comparing the Utilities normalized cost for power during the test year utilized in the last rate case with the Utilities normalized cost of power for the test year computed at the Utilities new increased or decreased cost of power.

B.    The total purchased power expense for water will be divided by the total gallonage sold during the test year to determine the Water Energy Cost (WEC) per 1000 gallons.

C.    The calculated increase or decrease in rates for the system must amount to at least $0.01 per 1000 gallons before an adjustment can be made.

E.    Utilities Division staff and the Finance department will annually calculate the energy charge amount for the water system based on the last twelve month rolling average of water related power costs.

F.    The WEC shall be approved annually prior to November 30 through the City Manager. In the first year of implementation the rate will not be adjusted due to partial fiscal year revenues. Revenues from the WEC fee will be posted to a separate revenue account.

G.    The new Water Energy Cost amount will be become effective on January 1st of each year.

H.    The Water Energy Cost shall be determined by the estimated total energy cost projected for the current fiscal year for water adjusted by actual prior fiscal year WEC account surplus or deficit divided by the current fiscal year projected water sold.

WEC = Total Annual Energy Cost/Total Annual Water Sold

Illustration of the Water Energy Charge calculation assuming the following test year data:

1.    2,500,000 TG Gallons Sold during past 12 months per 1000 gal.

2.    $1,875,000 Purchase Power Expense (Gas, Fuel, Electric)

3.    $0 Prior fiscal year WEC account end balance

The Water Energy Charge Pass Thru Calculation steps would be

WEC = ($1,875,000 -$0) / 2,500,000 = $0.75 per TG

7-03-001-0018 RECLAIMED WATER RATE SCHEDULE

There shall be charged the following rates for all reclaimed water furnished consumers and measured by meter on any service connection with City reclaimed water mains for and during each monthly billing period.

The base monthly service charge applies whether the reclaimed water meter is active or inactive. The monthly service charge is based on the fixed cost of operation and maintaining the reclaimed water system so that the system is available to provide water to the parcel when water service is activated. Parcels with shutoff reclaimed water meters will continue to pay base monthly service fee since water service is available and may be activated and used by the property owner at any time. Reclaimed water monthly service charge equal to water monthly service charge, see section 7-03-001-0011:
