15.35.050 Water meters and service lines.
Prior to the installation of the water service line, the engineer retained by the developer shall stake out the water meter location and provide the grade at which the lid is to be set.
Minimum service line size is three-quarter inch. All water service lines shall start with a corporation stop at the main and shall be of poly pipe with stiffeners or type “K” copper and meter setters of 21 inches or taller and braced, with dual unions at bottom of setter and meet height specs in a 21-inch can for water meters. A four-inch ring and lid shall be used and installed with the top of the setter at a depth of not less than 18 inches and not more than 22 inches from the lid of the meter box. Meters one and one-half inches and larger shall be placed in vaults (see Eagle Mountain standard drawing). All meter setters shall have dual check valves. Meter boxes shall be placed behind the sidewalk when there is no park strip and shall be placed three feet behind walk to center of can plus or minus three inches or in the planter if available so that a fence may be placed on property without interfering with the maintenance and reading of said meter. No meters shall be set in sidewalks or driveways. Meter boxes shall be in good repair and relatively free from obstruction to ensure ease in maintenance and reading (not full of dirt past the base of the meter, having trash present and being badly bent to create a hazard). Damaged boxes shall be replaced. Meter boxes shall be from level to one inch high from the final grade of sidewalk. See detail.
Lids shall have a one-inch hole in the top for the touch-read sensor and read “Eagle Mountain Water Meter” on lid.
Water service lines shall be minimum 18 inches vertical above the sewer. Water meters shall be located at the centerline of single-family lots unless authorized by the city engineer or his/her designee. On narrow lot subdivisions (lot width less than 50 feet), water laterals are to be located on alternating lot lines, although in no instances shall connections be made to the water main closer than three-foot intervals. Separation between water and sewer mains shall be 10 feet (horizontally) minimum unless authorized in writing by the city engineer or his/her designee.
A separate and independent service lateral for water service shall be provided for every building used as a dwelling, except in cases of undue hardship where the city council deems it necessary to make an exception. The water user shall bear full responsibility for the upkeep and maintenance of all water system lines and fixtures beyond the water meter.
From and after the effective date of the ordinance codified in this chapter, all dwelling units and premises under separate ownership shall be served by individual water meters, except in cases of undue hardship or in planned unit developments when approved by the city council. [Ord. O-09-2024 § 2 (Exh. A); Ord. O-13-2015 § 1 (Exh. A); Ord. O-03-2010 § 1 (Exh. A § 7.040)].
15.35.060 Water meter standards.
All water meters shall be purchased from the city. All structures, dwelling units, and establishments using water from the city culinary water system must have such number and size of water meters connected to their system as are necessary to meet the requirements of the Utah Plumbing Code. Meters will be furnished by the city at the expense of the property holder, at the city’s cost for said meter. Meter readings shall be taken at regular intervals as determined by the superintendent of the division and shall be submitted to the city treasurer for the purpose of making necessary billings for water service.
Water meters will not be placed in driveways or under sidewalks. If a water meter must be moved out of a driveway, the maximum lateral movement is 24 inches. If a fitting is required to allow the meter to be relocated, the contractor must notify the public utilities department so that an inspector can be present to verify the fitting is installed in accordance with city standards. Backfill and bedding on the relocated service lateral must conform to city standards and the engineered backfill (A1 or A2) requirement of the city. [Ord. O-09-2024 § 2 (Exh. A); Ord. O-13-2015 § 1 (Exh. A); Ord. O-03-2010 § 1 (Exh. A § 7.050)].
15.35.070 Tapping of water lines.
Tapping valves may only be used when previously approved by the city engineer or his/her designee. Tapping saddles with an “O” ring may be used if the water main line to be tapped is larger than the new water main line. Where the tap is the same size as the existing main, cast iron or stainless steel tapping sleeves shall be used, which encase the full perimeter of the pipe. The valve shall be a tapping valve with a guide lip on the flanged side. The opposite side of the valve shall have a mechanical joint connection.
Service taps shall be a minimum of 36 inches apart. No taps will be allowed within 36 inches of the end of the pipe joints and fitting, not including the joints in the measurement. [Ord. O-09-2024 § 2 (Exh. A); Ord. O-13-2015 § 1 (Exh. A); Ord. O-03-2010 § 1 (Exh. A § 7.060)].
15.35.080 Testing and flushing.
A. A minimum pressure 50 percent in excess of the maximum line operation pressure (or 200 pounds, whichever is greater) shall be maintained on the portion being tested for a minimum period of two hours, using either pneumatic or hydraulic means to maintain the pressure. After installation, fire hydrants must be covered with a black garbage bag taped down until all testing has been completed.
B. After pressure testing, all pipelines shall be flushed. Flushing shall be accomplished through hydrants or, if a hydrant does not exist at the end of the line, the contractor shall install a tap sufficient in size to provide for two-and-one-half-foot-per-second flushing velocity in the line.
C. A leakage test shall be conducted concurrently with the pressure test.
1. “Leakage” shall be defined as the quantity of water that must be supplied into the newly laid pipe, or any valved section thereof, to maintain pressure within five psi of the specified test pressure after the air in the pipeline has been expelled and the pipe has been filled with water.
2. Allowable Leakage. No pipe installation will be accepted if the leakage is greater than that determined by the following formula:
|
L = |
SD(P)0.5 |
|
|
133,200 |
in which L is the allowable leakage, in gallons per hour; S is the length of pipeline tested, in feet; D is the nominal diameter of the pipe, in inches; and P is the average test pressure during the leakage test, in pounds per square inch gauge.
a. Allowable leakage at various pressures will be provided by inspectors.
b. When testing against closed metal-seated valves, an additional leakage per closed valve of 0.0078 gallon/hour/inch of nominal valve size shall be allowed.
c. When hydrants are in the test section, the test shall be made against the closed hydrant.
3. Acceptance of Installation. Acceptance shall be determined on the basis of allowable leakage. If any test of pipe laid discloses leakage greater than specified, the contractor shall, at its own expense, locate and repair the defective material until the leakage is within the specified allowance.
D. All visible leaks are to be repaired regardless of the amount of leakage.
E. All new water systems or extensions to existing systems shall be thoroughly flushed before being placed in service. Flushing shall be accomplished through hydrants, or end-of-line blowoff assemblies at a minimum flushing velocity of two and one-half feet per second.
F. The following is the flow quantity required to provide a two-and-one-half-foot-per-second flushing velocity:

15.35.090 Disinfection of water lines.
A. Disinfection of water mains shall be done in accordance with the latest edition of AWWA C651.
B. The pipe shall be clean prior to disinfection. If, in the opinion of the city, contamination is such that it cannot be removed by flushing, the pipe shall be cleaned by mechanical means and then swabbed with a one percent hypochlorite disinfection solution.
C. The pipeline shall be disinfected as outlined in AWWA C651. Chemicals to be used shall conform to one of the following: AWWA B300, hypochlorite; AWWA B301, liquid chlorine; AWWA B302, ammonium; and AWWA B303, sodium chlorite.
The tablet method shall consist of placing calcium hypochlorite tablets at the specified rate in the main during construction at the upstream end of each section of pipe. The tablet shall be attached with an adhesive, such as Permatex No. 1 or equal. The line shall then be filled slowly (velocities less than one foot/second), expelling all air pockets and maintaining the disinfection solution in the line for at least 24 hours, or 48 hours if the water temperature is less than 41 degrees Fahrenheit. The disinfection solution shall have a concentration of at least 25 mg/L of available chlorine. The continuous feed shall be done exactly as outlined in AWWA C651 and shall have 25 mg/L available chlorine after 24 hours. Under both methods the contractor shall not be allowed to flush the line until the chlorine residual test has been passed by the city.
D. After the chlorination, the line shall be thoroughly flushed with velocities greater than two and one-half feet/second with clean water and if necessary re-chlorinated until satisfactory bacteriological testing is obtained. If any of the tests fail, the contractor shall be responsible for the fees of additional tests. All new lines shall be isolated from existing lines when tested.
E. Following the approval of the testing and installation of a water main, the entire water line will be flushed through the end of the main via an approved outlet.
F. The contractor shall take bacteria samples at the sites designated by the public works director or his/her designee for each job, based on the following formula:
1. a. Minimum of one sample up to 200 feet.
b. Minimum of two samples up to 600 feet. (One in the middle and one on the end.)
c. Minimum of one sample every 600 feet.
d. Sampling points to be established during the preconstruction meeting for each project.
2. If any sample point fails on the first test, the line will be flushed and retested at all sample points.
3. If any sample point fails a second time, the complete line will be re-disinfected and retested at all sample points.
4. If any samples come back marked “present” or “unsatisfactory,” which means coliform bacteria is present, the line will be redisinfected and retested at all sample sites.
5. After passing test let system “relax” 24 hours then take subsequent test.
6. After second test of samples is acceptable system is ready for use.
G. Bacteriological reports shall consist of the following:
1. Date issued, project name, and the name, address, and telephone number of the testing laboratory.
2. Date and time of water sample.
3. Name of person collecting samples.
4. Test locations.
5. Initial and 24-hour disinfection residuals in ppm for each outlet tested.
6. Coliform bacteria test results for each outlet tested.
7. Certification that water conforms, or fails to conform, to bacterial standards of the state.
Water services will not be installed until bacteria sample results have been approved by the city engineer or his/her designee. [Ord. O-09-2024 § 2 (Exh. A); Ord. O-13-2015 § 1 (Exh. A); Ord. O-03-2010 § 1 (Exh. A § 7.080)].
15.35.100 Backflow prevention and cross-connection control rules and regulations.
This section enacts the cross-connection control and backflow prevention requirements applicable to the water system which is owned and operated by Eagle Mountain City.
A. Definitions.
1. “City” means Eagle Mountain City.
2. The city engineer, the water division director and the public works director are vested with the authority and responsibility for the implementation of the city’s cross-connection control program.
3. “Approved backflow assembly” means a backflow assembly accepted by the Utah State Drinking Water Division as meeting an applicable specification or as suitable for the proposed use.
4. “Auxiliary water supply” means any water supply on or available to the premises other than the city’s public water supply. These auxiliary waters may include water from another public potable water supply or any natural source, such as a well, spring, river, stream, harbor, irrigation water, used-water storage tanks or reservoirs which may or may not originate within the city. These waters may be contaminated or polluted or they may be objectionable and constitute an unacceptable water source over which the city does not have authority for sanitary control.
5. “Backflow” means the reversal of the normal flow of water caused by either back-pressure or back-siphonage.
6. “Back-pressure” means the flow of water or other liquids, mixtures, or substances under pressure into the distribution pipes of a potable water supply system from any source or sources other than the intended source.
7. “Back-siphonage” means the flow of water or other liquids, mixtures, or substances into the distribution pipes of a potable water supply system from any source other than the intended source, caused by the reduction of pressure in the potable water supply system.
8. “Backflow prevention assembly” means an assembly or means designed to prevent backflow. Specifications for backflow prevention assemblies are contained within the Utah Plumbing Code, Chapter 10 (Appendix J), and the Cross-Connection Control Program of Utah. All backflow prevention assemblies must be approved by the Utah State Drinking Water Division prior to installation. A listing of these approved backflow prevention assemblies may be found in the Cross-Connection Control Program for Utah.
9. “Contamination” means an impairment of the quality of the potable water supply by sewage, industrial fluids or waste liquids, irrigation or other nonpotable water, compounds or other materials to a degree which creates an actual or potential hazard to the public health through poisoning or through the spread of disease.
10. “Cross-connection” means any physical connection or arrangement of piping or fixtures between two otherwise separate piping systems, one of which contains potable water and the other water from a noncity source or nonpotable water or storage tanks or reservoirs of questionable safety, through which, or because of which, backflow may occur into the potable water system; including any temporary connections, such as swing connections, removable sections, four-way plug valves, spools, dummy sections of pipe, swivel or changeover devices or sliding multiport tubes.
11. “Cross-connection – controlled” means a connection between a potable water system and water from a noncity source or a nonpotable water system with an approved backflow prevention assembly properly installed and maintained so that it will continuously afford the protection commensurate with the degree of hazard.
12. “Cross-connection – containment” means the installation of an approved backflow assembly at the water service connection to any user’s premises where it is physically and economically infeasible to find and permanently eliminate or control all actual or potential cross-connections within the user’s water system, or the installation of an approved backflow prevention assembly on the service line leading to and supplying a portion of a user’s water system where there are actual or potential cross-connections which cannot be effectively eliminated or controlled at the point of the cross-connection (isolation).
13. “User” means a dwelling or other service connected to the city water system regardless of the location within or outside the boundary of the city.
B. 1. An approved backflow prevention assembly shall be installed on each service line to a user’s water system, at or near the property line, or immediately inside the building being served, but in all cases before the first branch line leading off the service line, whenever the city determines that such is necessary for protection of the water supply or in the best interest of the users of the city’s water supply system.
2. The type of protective assembly required under this subsection shall depend upon the degree of hazard which exists at the point of cross-connection, i.e., whether direct or indirect, as defined in the Utah Plumbing Code.
3. All presently installed backflow prevention assemblies which do not meet the requirements of this section but were approved assemblies for the purposes described herein at the time of installation and which have been properly maintained shall, except for the inspection and maintenance requirements listed in subsection F of this section, be excluded from the requirements of these rules so long as the city believes that they will satisfactorily protect the public water system. Whenever the existing assembly is moved from the present location or requires more than minimum maintenance or when the city finds that the maintenance of this assembly constitutes a hazard to health, the unit shall be replaced by the user with an approved backflow prevention assembly meeting the requirements of this chapter.
4. No water service connection to any premises shall be installed by any user of the city’s potable water system or maintained by the user unless the water supply is protected as required by state laws, regulations and codes, and the provisions of this chapter. Service of water to any premises shall be discontinued by the user if a backflow prevention assembly required for control of backflow and cross-connections is not installed, tested and maintained, or if it is found that a backflow prevention assembly has been removed or bypassed, or if an unprotected cross-connection exists on the premises. Service will not be resumed by any user until such conditions or defects are corrected, and the city shall not furnish potable water to the premises of any user known by the city to be lacking suitable backflow prevention assemblies.
5. The user’s system shall be open for inspection at all reasonable times to authorized representatives of the city to determine whether cross-connections or other structural or sanitary hazards, including violations of this chapter, exist. When such a condition becomes known, the city shall deny or immediately discontinue service to the premises by providing a physical break in the service line until the customer has corrected the condition in conformance with the state statutes and city regulations.
C. If, in the judgment of the director, an approved backflow prevention assembly is required at the user’s private water system for the protection of the public potable water distribution system from contamination or pollution due to the backflow of contaminants through water service connections, the city or its designated agent shall give notice in writing to such user to install an approved backflow prevention assembly at a specific location or locations on his/her premises. Within 10 days after receipt of written notice, the user shall install such approved assembly at the user’s own expense, and failure, refusal or inability on the part of the user to install, have tested, and/or maintain said assembly shall constitute grounds for discontinuing water service to the premises until such requirements are met.
D. The building official shall have the responsibility to review building plans and inspect plumbing as it is installed and to prevent cross-connections from being designed and built into structures which will connect to the water system. Where the review of building plans suggests or indicates potential for a cross-connection being made an integral part of the plumbing system, the building inspector shall require such cross-connections to either be eliminated or provided with an approved backflow prevention assembly in accordance with the plumbing code.
E. When employed by the user or the city to test, repair, overhaul and/or maintain backflow prevention assemblies, a backflow assembly technician shall have the responsibility and obligation:
1. To ensure that acceptable testing equipment and procedures are used for testing, repairing, or overhauling backflow prevention assemblies.
2. To make reports of such testing and/or repair to the user and the city, such reports to include the list of materials or replacement parts used.
3. To ensure that replacement parts are equal in quality to parts originally supplied by the manufacturer of the assembly being repaired.
4. To not change the design, material, or operational characteristics of the assembly during repair or maintenance.
5. To perform the work and be responsible for the competence and accuracy of all tests and reports.
6. To ensure that his license is current, and that the testing equipment being used is acceptable to the state of Utah and the city and is in proper operating condition.
7. To report a failing assembly to the city within five working days from the date the failure was detected. Failure to do so may be grounds for revocation of the technician’s certification.
8. To be equipped with and be competent in the use of all necessary tools, gauges, and other equipment necessary to properly test, repair, and maintain backflow prevention assemblies.
9. To tag each double check valve, pressure vacuum breaker, reduced pressure backflow assembly and air gaps, showing the serial number, date tested and by whom. The technician’s license number must also be on such tag.
10. In the case of a user requiring a commercially available technician, any certified technician is authorized to make the test and report the results of the same to the user and the city. If such a commercially tested assembly is in need of repair, the same shall be performed by a plumber licensed pursuant to Utah statutes.
F. 1. It is the duty and responsibility of the user at any premises where backflow prevention assemblies are installed to have certified inspections and operational tests made at least once per year at the user’s expense. In those instances where the city deems the hazard to be great, it may require certified inspections and tests at more frequent intervals. All inspections and tests shall be performed by a certified backflow assembly technician, licensed through the state of Utah, and shall be made in accordance with the standards set forth by the Utah State Drinking Water Division.
2. Backflow prevention assemblies shall be installed in water supply lines to provide at least the degree of protection provided in the Utah Plumbing Code, Chapter 10 (Appendix J). All backflow prevention assemblies shall be exposed for easy observation and be readily accessible.
3. All backflow prevention assemblies installed in a potable water supply system for protection against backflow shall be maintained in good working condition by the user or other person or persons having control of such assemblies. The Utah State Drinking Water Division and the city may inspect such assemblies and, if found to be defective or inoperative, shall require the replacement thereof. No assembly shall be removed from use, relocated, or another assembly substituted without the approval of the city.
4. Each user shall cause all backflow prevention assemblies to be tested within 10 working days of installation.
5. No backflow prevention assembly shall be installed so as to create a safety hazard, e.g., installed over an electrical panel, steam pipes, boilers, pits, or above ceiling level. [Ord. O-09-2024 § 2 (Exh. A); Ord. O-13-2015 § 1 (Exh. A); Ord. O-03-2010 § 1 (Exh. A § 7.090)].
15.35.110 Water system extensions.
All extensions to the existing water system which are not covered by regulations in the approval of subdivisions and large-scale developments shall comply with the provisions of this section.
A. Any person desiring to extend the water system may make application to the city council. Such application shall be considered by the city council on a case-by-case basis and the council shall approve such applications if (1) the proposed extension is to be constructed consistent with the city’s extension standards, (2) there is adequate reserve water available to supply said need, and (3) the existing distribution system is adequate to supply the needed water to the point of beginning of the extension.
B. The application shall contain a description of the proposed extension accompanied by a map showing the location thereof. Detailed engineering drawings showing the location and size of all lines, mains, service laterals, appurtenant facilities, anticipated water pressures and fire flows shall be included. The application shall also include an extension agreement signed by the applicant in a form approved by the city council by which the applicant agrees to construct the facilities, both on-site and off-site, and accepts the conditions agreeing to reimbursement as outlined in subsection F of this section.
C. Before any such application is approved, the city council shall refer it to the water division superintendent for his review and comment. The application may also be referred to the planning commission and the city engineer for similar review and recommendation.
D. The design, location, materials and methods and standards of construction of water line extension shall be in accordance with city standards and specifications as approved by the city council.
E. The city council may require the construction of oversized and off-site facilities as a condition of the approval of any application governed by this section.
F. Upon completion of an extension, the applicant’s share of the actual cost of making such extension shall be determined by the city engineer from as-built drawings to be provided by the applicant. Whenever an extension of a water main benefits property which is adjacent to the extension or extended from the end of an existing extension, other than that which is owned by the applicant, the city will enter a deferred credit on its books and records in the amount of the actual prorated cost of extension across the front of said benefited property and shall reimburse the applicant, his assignees or successors, upon collection by the city of charges assessed against such benefited property as service connections are made. All such reimbursements shall extend for a period determined by the city council from the date of the completion of the extension and acceptance by the city, or until the initial prorated cost of the extension along the frontage not owned by the applicant shall have been refunded.
A water main extension charge for each and every subsequent service connection to an extension under the provisions of this section shall be paid before such service connection is made, except for frontage owned by the applicant at the time of the application. The water main extension charge is separate and is in addition to any service connection charge required by the city. Extension of an existing water service main shall require a construction valve to isolate the new construction for testing and flushing purposes. A blow off at the terminus of the water main shall be required unless a suitable alternative such as proximity to a fire hydrant is approved by the city engineer or his/her designee.
The amount of an extension charge to benefited property shall be determined by the city council. All necessary fire hydrants and appurtenances that are provided in making the extension shall be included in determining reimbursement.
All extension charges levied for purposes of reimbursement shall be determined using the costs for installing water mains of eight inches in diameter. Where the city requires that the extension be made using larger lines, the difference between the cost of installing an eight-inch water line and the size required by the city may be subject to reimbursement by the property owners which are served by said extension in accordance with the city’s reimbursement policy. All cost for the line size over eight inches shall be borne by the city upon approval of the city council. All main water line extensions become the property of the city upon acceptance by the city. [Ord. O-09-2024 § 2 (Exh. A); Ord. O-13-2015 § 1 (Exh. A); Ord. O-03-2010 § 1 (Exh. A § 7.100)].
15.35.120 Water fittings.
All water line fittings to have Megalug followers or approved fittings. All fittings, valves, saddles and other parts that have a likelihood to corrode shall be completely greased (food grade) and wrapped (eight millimeters minimum). Anti-corrosion (anode) pits may be required in highly corrosive soils (based on soils report or on-site testing).
All water main crosses and tees shall have a valve on all legs of the cross or tee. Valves shall be flanged directly to the cross or tee. Water mains of 10 inches or smaller shall require a gate valve. Mains 12 inches or larger shall require a butterfly valve unless authorized in writing by the city engineer or his/her designee.
Use ductile iron fittings that conform to the provisions of ANSI/AWWA C110/A21.10 or C153/A21.53 unless otherwise recommended by the manufacturer and authorized by the city engineer or his/her designee. All PVC pipes being inserted into fittings shall have the bevel end removed. [Ord. O-09-2024 § 2 (Exh. A)].
