A punch list shall be issued for corrective work if needed. However, the city engineer shall not perform the contractor's work by finding all of his problems before the project is reasonably complete.

B.

Compaction testing.

1)

All trenches shall be subject to compaction testing after backfilling and shall meet the compaction requirements set forth in section 110.02.04.H.

2)

All trenches failing to meet compaction requirements shall be excavated and re-compacted and retested. This process shall continue until a passing test is achieved.

3)

All costs of compaction testing shall be the responsibility of the developer.

C.

Fire hydrant and valve testing.

1)

All fire hydrants shall be tested per section 110.02.03 and flushed to check the operation of the hydrant.

2)

All valves shall be located and their operation checked. All valves shall be left fully open.

D.

Water system testing.

1)

General.

a.

All lines designed to operate under pressure shall be successfully tested. Tests of installed piping shall consist of a pressure and leakage test and a disinfection test.

b.

All piping to be tested must satisfactorily comply with these tests before being eligible for acceptance. In general, tests shall be conducted in accordance with AWWA C600 and C651 except as otherwise herein specified.

2)

Pressure and leakage testing.

a.

After all piping has been placed, each section between line valves shall be tested by the developer's contractor in the presence of the city engineer or his designated representative and tests shall be continued until all leaks have been made tight to the satisfaction of the city. The contractor shall furnish all necessary meters, pumps, gauges, bulkheads, and other materials and appliances necessary to conduct the test as herein required. Every precaution must be taken to valve-off or otherwise protect control equipment in or attached to the pipe line to prevent damage thereto.

b.

Before applying the specified test pressure, all air shall be expelled from the pipe. If hydrants, blow-offs or air release valves are not available at the high places, the contractor shall make the necessary taps at points of highest elevation before the test is made and insert plugs before the test has been completed.

c.

Prior to the pressure test, pipe laid in trenches shall be backfilled adequately to secure the pipe during the test. Any observed leakage shall require corrective measures to pipe lines and/or joints to the satisfaction of the city engineer.

d.

The city will furnish the necessary water for testing and disinfection of the lines; however, any water lost through breakage of lines or unnecessary or excessive flushing of lines will be charged to the contractor at the current residential rate.

e.

All lines shall be tested to a pressure of one and one-half times the working pressure at the lowest point of the system to be tested. Test duration shall be two hours. However, test pressure shall not exceed pipe, valve and/or thrust-restraint design pressures. The city engineer or his representative may require a 24-hour test if he so desires. Test pressure shall not vary by more than plus five psi for the duration of the test which may require periodic pumping (in which case the added water will be counted as part of the leakage). Lines shall be tested in sections between the valves. The rate of leakage shall not exceed 13.5 gallons per 24 hours per inch diameter per mile of water main. (See table 110-4.)

Table 110-4 Leakage Tabulation

f.

Any section of the line not meeting the above test shall have the leaks found and corrected at once and re-tested until the leakage falls within the limits specified above. Leakage testing must be witnessed and approved by the city.

3)

Disinfection. After leakage testing and all necessary repairs have been made, the contractor shall flush and disinfect all potable water mains and equipment installed in strict accordance with AWWA Standard for Disinfecting Water Mains, C651, latest revision.

a.

The method of disinfection shall be the continuous — feed method as per AWWA C651, latest revision, section 4.4.3. Care shall be taken in filling the mains so that entrained air is drawn from the pipes at all high points so as to permit intimate contact of the disinfection agent with the entire inside surface of the pipe and appurtenances. The potable water shall be chlorinated so that after a 24 hour holding period in the main, there will be a free chlorine residual of not less than ten mg/L at all points in the system when tested with a standard orthotolindine solution.

b.

The form of chlorine shall be a one percent solution made from either sodium hypochlorite or calcium hypochlorite which shall be measured and pumped into the pipeline. Water must be flowing during the feeding operation and the injection point must be located so that the flow of water will disperse the chlorine throughout the pipeline. AWWA C651 requires the injection point be located at a point not more than 10 feet from the point of connection to the existing water supply. The chlorine should be fed at a constant rate such that the water will have not less than 25 mg/L free chlorine. Table 110-5 gives the amount of chlorine required for each 100 feet of pipe of various diameters to produce a 25 mg/L concentration.

Table 110-5 Chlorination Tabulation

c.

After 24 hours, the line shall be flushed until the chlorine content is not more than two parts per million. When this step is completed, the developer will notify the city engineer so as to schedule the taking of the water sample for the bacteria test. If the samples show evidence of contamination upon testing, the above procedure of disinfection shall be repeated until approved samples are obtained. No connections shall be made to the existing system until all of the samples have been tested and approved by the city engineer. The developer may be required to add additional taps for bleeding purposes at the ends of water mains or wherever necessary for taking samples.

d.

The contractor shall dechlorinate the highly-chlorinated water being flushed from the water main to open areas where the discharge will not damage the roadbed or adjacent property.

e.

The chlorine residual of water being disposed may be neutralized by treating the water with one of the chemicals listed in table 110-6:

Table 110-6 Chemical Required*

*

Amounts of chemicals required to neutralize various residual chlorine concentrations in 100,000 gal (378.5 m ³ ) of water.

Water System Facilities

(Ord. No. 2014-18, § 2, 8-21-2014)

A.

Introduction.

1)

A cross-connection can be generally defined as a physical connection between two otherwise separate piping systems or vessels, one of which contains potable water and the other does not. There are two main approaches to provide against actual or potential cross-connections, the "fixture outlet" approach and the "containment" approach.

2)

With the "fixture outlet" approach, cross-connection control protective devices are placed at internal high hazard locations within the customer's internal water system as well as at all locations where cross-connections exist at the "last free-flowing outlet." This approach entails extensive cross-connection survey work on behalf of the water purveyor as well as constant policing of the plumbing within each customer's premises. In a large water supply system, fixture outlet protection is virtually impossible to achieve and police due to the quantity of systems involved, the complexity of the plumbing systems inherent in many industrial sites, and the fact that plumbing changes are made within industrial and commercial establishments that do not require approval or permitting.

3)

The "containment" approach isolates the customer from the water main at all service connections, utilizing a minimum number of backflow devices throughout the system. Although this approach does not protect the customer within the building, it does effectively remove the possibility of contamination to the public water supply.

4)

Due to the number of commercial customers and the difficulties associated with "fixture outlet" protection, the "containment" approach will be employed by the City of Canton for protection of the public water supply.

B.

Purpose. The purpose of the City of Canton Cross-Connection Control Program includes the following:

1)

To protect the public water supply served by the City of Canton Water System from the entry of contaminants or pollutants into the system through the control of cross-connections. Control of contaminants or pollutants which could backflow or back-siphon into the public water system shall be accomplished by isolation and containment at the service connection.

2)

To promote and encourage the elimination or control of existing cross-connections, actual or potential, between the customer's in-plant potable water system and nonpotable water systems, plumbing fixtures and industrial piping systems.

3)

To provide for the maintenance of a continuing program of cross-connection control which will effectively prevent the contamination or pollution of all potable water systems by cross-connection.

C.

Authority. The Georgia Rules for Safe Drinking Water (391-3-5-13) state that a water supplier has the responsibility to prevent water from unapproved sources or any contaminants from entering the public water system. In partial fulfillment of this responsibility, the rules require that the water supplier develop a written program for the elimination and prevention of all cross-connections when requested by the Georgia Environmental Protection Division (EDP).

D.

Applicability. The provisions of backflow prevention by isolation and containment are applicable to any customer or system supplied by the City of Canton's water distribution system including irrigation sprinklers, fire protection systems, residential systems, and other service connections.

E.

Responsibilities.

1)

The Council of the City of Canton is responsible for establishing regulations regarding the control of cross-connections to the public distribution system.

2)

The city engineer is responsible for the enforcement of these regulations in an effort to protect the public water supply system through the prevention of backflow or back siphonage of contaminants or pollutants. This responsibility begins with the production of water and extends throughout the distribution system to the service connection, applying to new construction as well as to existing customers and situations.

3)

The City of Canton Building Department is responsible for enforcing the city's adopted plumbing code regulations in an effort to prevent backflows on the customer's premises from entering the customer's own potable water system. This responsibility extends to both new and existing customers.

4)

The water customer is responsible for complying with the city regulations including maintenance, testing, and reporting on certain devices.

a.

Customers are required to allow on-site inspections to verify compliance with the city's cross-connection control program.

b.

The customers have a dual responsibility for protecting the water in their own system from degradation due to conditions originating on their premises and for protecting the quality of water in the public distribution system.

c.

The customer is liable for any health hazard due to backflow from unprotected cross-connections on their premises.

d.

The customer is responsible for the costs of procurement, installation, testing, and maintenance of al backflow prevention devises on their premises and serving their premises.

F.

Reference material. The manuals listed below provide information relating to cross-connection control and backflow prevention.

1)

Cross-Connection Control Manual, U.S. EPA Office of Water, June 1989, EPA 570/9-89-007.

2)

Cross-Connection Control Manual, Ninth Edition. The EPA Cross Connection Control Manual defines, describes, and illustrates typical cross-Connections and suggest simple methods and devices to eliminate them.

3)

Recommended Practice for Backflow Prevention and Cross Connection Control, AWWA Manual M14, 2nd edition, 1990. The AWWA manual sets forth criteria for the selection and installation of backflow prevention devices and outlines procedures and techniques for maintenance and inspection of these devices.

(Ord. No. 2014-18, § 2, 8-21-2014)

A.

Hazard assessment.

1)

Two degrees of hazard are considered, as determined by whether the impurities potentially involved are contaminants or pollutants. The two degrees of hazard, health and nonhealth, are defined below based on definitions given in the AWWA Manual M14 2nd edition:

a.

Health (contaminants). A cross-connection or potential cross-connection involving any substance that could, if introduced into the potable water supply, cause death, illness, spread disease, or have a high probability of causing such effects.

b.

Nonhealth (pollutants). A cross-connection or potential cross-connection involving any substance that generally would not be a health hazard, but would constitute a nuisance, or be aesthetically objectionable, if introduced into the domestic water supply.

2)

Chapter 4 in the AWWA Manual M14 provides guidance for the assessment of hazard and selection of backflow protection assemblies for premises isolation. Information from the chapter is summarized in table 110-7. Chapter 5 of the AWWA Manual M14 and chapter 2 of the EPA Cross-Connection Control Manual provide additional examples and illustrations of customer types and typical cross-connections that pose hazards to the public water supply system.

Table 110-7: Guidance for the Assessment of Hazard and Selection of Assemblies for Premises Isolation

B.

New customers.

1)

The city building department shall review all plans for new construction and shall advise developers of regulations in advance and determine that appropriate protection measures and devices are proposed.

2)

New construction will be inspected for City of Canton plumbing code compliance by inspectors in the city building department to determine that individual cross-connections are isolated from the public water supply.

3)

The city will inspect all new service connections for cross-connection control compliance and determine the degree of hazard to the public water supply. Based on the hazard assessment, the city will require the customer to install an appropriately selected backflow prevention device.

4)

Devices required by either the city building department or the cross-connection control program will be installed at the developer, builder, or owner's expense.

5)

The city will refuse service in cases of noncompliance.

C.

Fire protection systems.

1)

If the service connection to a premise is intended to be used for fire protection it shall be classified and/or defined as follows in table 110-8:

Table 110-8 Fire Protection Systems — 1

2)

The terminology and definitions for types of fire protection systems presented in table 110-9 shall also be applicable.

3)

Sprinkler systems shall be further classified in accordance with table 110-10.

4)

Standpipe systems shall be further classified as follows in accordance with table 110-11.

Table 110-9 Fire Protection Systems — 2

Table 110-10 Sprinkler System Classifications

Table 110-11 Standpipe System Classifications

5)

Fire protection systems as defined by the International Fire Code shall be contained from the City of Canton Water System by backflow prevention devices that have approvals as required and are classified or listed by the Underwriters Laboratories and Factory Mutual Insurance as follows:

a.

Class I, II, III sprinkler systems and nonhazardous standpipe or combined systems shall be contained by the installation of a double detector check valve (DDC BFP).

b.

Class IV, V and VI sprinkler systems and hazardous standpipe or combined systems shall be contained by the installation of a reduced pressure zone detector check (RPDC BFP).

c.

Class systems with combination hazards shall be contained from the public water mains by procedures applicable to the component that requires the higher degree of protection.

6)

Single detector checks that are used on nonhazardous fire protection systems class I, II, or III may not considered as a component part of a DDC BFP. Specifically, the addition of a second single check to one of these devices may not be substituted for a DDC assembly that is approved for backflow prevention.

7)

It is intended that the approved DDC BFP be in lieu of, not in addition to, the checking devices already required by the Standard Plumbing Code in the supply to class I, or II, or the DCV BFP already required on class III nonhazardous systems, and that the approved RPDC be in lieu of the RPZ already required on hazardous systems. The only additional checking device intended is a three-quarter-inch DCV or RPZ BFP in the three-quarter-inch copper bypass line, in conjunction with the bronze detector meter.

8)

The purpose of certain checking devices used, or likely to be used, with fire protection systems is given below to call attention to those that are approved for use as backflow prevention devices and those that are not.

Table 110-12 Fire Protection System Checking Devices Approved for Use as Backflow Prevention Devices

9)

The shutoff valves required for periodic testing of the backflow prevention device shall be outside stem and yoke (OS&Y), FDA-approved fused epoxy coated inside and out, with resilient seats, and the inlet valve shall include an approved test cock on the upstream side. All components shall be listed for fire protections service by Underwriters Laboratories and Factory Mutual. The exception is that ball valves may be utilized for shut off means on pipe sizes below two inches as approved by the cross-connection program administrator.

10)

The city has a designated cross-connection control program administrator. The program administrator shall coordinate and perform site inspections, provide customer notifications, and maintain all correspondence and records. The record system shall facilitate the monitoring of the following:

a.

Installation date of assemblies;

b.

Location of assemblies;

c.

Inspection and testing of assemblies;

d.

Performance of licensed testers;

e.

Calibration of testing devices.

11)

Tasks to be performed annually:

a.

Update list of potential sources of contaminants and pollutants;

b.

Notify customers of testing requirements for installed backflow prevention devices;

c.

Update list of approved backflow devices and approved tests.

D.

Backflow prevention devices.

1)

Selection.

a.

Backflow prevention devices shall be selected based on the degree of hazard assigned to the customer as follows:

i.

Those customers that are categorized under the health degree of hazard shall be required to install an approved reduced-pressure zone backflow-prevention assembly (RPZ) and have the device tested for proper operation annually.

ii.

Those customers that are categorized under the nonhealth degree of hazard shall be required to install an approved double check valve assembly (DCVA) and have the device tested for proper operation annually.

b.

Refer to the hazard assessment section (see subsection A above) of this section for guidelines regarding the selection of backflow prevention devices for particular customer types.

c.

Lawn sprinkler systems are open to the atmosphere and are not classified as a pressure type cross-connection. However, due to the special nature of the system, if no chemicals are injected into the system, the minimum protection against backflow shall include a double check valve assembly. If chemicals are injected or connections are made so that chemicals could be injected easily, minimum protection shall include a reduced pressure zone type backflow prevention device.

d.

Water being introduced into a vessel, tank, tanker truck, or miscellaneous other containers from any connection to the City of Canton Water System shall be through a method approved by the city engineer. Drawing 5 of chapter 112 of this UDC shows three approved methods for filling tanks.

2)

Approval devices.

a.

All backflow prevention devices shall be approved in accordance with the applicable standards of the American Society of Sanitary Engineering, the American Water Works Association, and the University of Southern California Foundation of Cross Connection Control and Hydraulic Research. Final approval acceptable devices will rest with the program administrator. A list of approved devices is maintained by the Canton Engineering Department.

b.

If no standard yet exists for particular device, or if the device is a derivative on one covered by a national standard, the program administrator shall determine whether the device shall be allowed on the water service connection.

3)

Installation of devices.

a.

The location of all backflow prevention devices shall be in an area that provides a safe working environment for testing and maintenance. The area shall be readily assessable, dry, and free from dirt, extreme cold or heat, and electrical hazards.

b.

Facilities that require a continuous, uninterrupted water supply shall install backflow prevention devices in parallel for testing and maintenance purposes. In no case shall a bypass arrangement be installed without approval of the cross-connection program administrator.

c.

Backflow prevention devices equipped with atmospheric vents, or with relief openings, shall be so installed and so located as to prevent any vent or any relief opening from being submerged. They shall be installed in the position as recommended by the manufacturer, and shall be protected from freezing. Illustrations of typical installations of backflow prevention devices can be found in chapter 112 of this UDC. The following guidelines shall govern the installation of backflow prevention devices:

i.

Backflow prevention device—Double check valve assembly (DCVA). This device shall not be buried in earth but may be installed below ground in a pit provided ball valve test cocks fitted where brass plugs are used. A positive shutoff valve shall be near the inlet and outlet sides of the device, and three ball valve test cocks provided on the device. A fourth test cock shall be provided on the upstream side of the inlet shut-off valve. When below ground, a union or flange shall be near the inlet and outlet sides. No intervening connections shall be between the shut-off valves and the backflow prevention device.

ii.

Backflow prevention device—Reduced-pressure zone assembly (RPZ). This device shall not be installed below ground. Where relief valve discharge could cause water damage, it shall be piped via an air gap, or a funnel, at the vent/relief port to a floor drain or other approved location. A positive shutoff valve shall be near the inlet and outlet sides of the device, and three approved test cocks provided on the device. A fourth test cock shall be provided on the upstream side of the inlet shutoff valve. A bronze strainer with 20-mesh stainless steel screen shall be included between the inlet shutoff valve and the device on sizes through two-and-one-half-inch. No intervening branch connection(s) shall be between the shutoff valves and the backflow prevention device. When the reduced pressure zone device is installed in a line subject to periodic no-flow conditions and the supply pressure is subject to fluctuations, an auxiliary directional check with soft disc, capable of functioning in any installed position of the RPZ, shall be provided between the inlet shutoff valve and RPZ head to lock the supply pressure in, and percent discharge through the vent/relief port. When a water pressure-reducing valve is required in the same line with the RPZ device, it is usually possible to locate the reducing valve upstream of the device and take advantage of the check valve effect of the reducing valve.
