(A) Installation of backflow prevention assembly. No cross-connections or conditions, which might permit potentially the backflow of contaminants and/or pollutants from a customer/user's piping system into the public water distribution system shall be permitted. An approved backflow prevention assembly shall be installed on each service line to a customer'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.
(B) Type of protective assembly. The type of protective assembly required shall depend upon the degree of hazard which exists as follows:
(1) In the case of any premises where there is an auxiliary water supply, the public water system shall be protected by an approved air gap separation or an approved reduced pressure principle backflow prevention assembly;
(2) In the case of any premises where there is water or a substance that would be objectionable but not hazardous to health, if introduced into the public water system, the public water system shall be protected by an approved double check valve assembly;
(3) In the case of any premises where there is any material dangerous to health such as to create an actual or potential hazard to the public water system, the public water system shall be protected by an approved air-gap separation or an approved reduced pressure principle backflow prevention assembly. Examples of premises where these conditions will exist include, but are not limited to sewage treatment plants, sewage pumping stations, chemical manufacturing plants, hospitals, mortuaries and plating plants;
(4) In the case of any premises where there are uncontrolled cross-connections, either actual or potential, the public water system shall be protected by an approved air-gap separation or an approved reduced pressure principle backflow prevention assembly at the service connection;
(5) In the case of any premises where, because of security requirements or other prohibitions or restrictions, it is impossible or impractical to make a complete in-plant cross-connection survey, the public water system shall be protected against backflow from the premises by either an approved air-gap separation or an approved reduced pressure principle backflow prevention assembly on each service to the premises;
(6) In the case of any premises having a lawn irrigation system, the public water system shall be protected by an approved pressure vacuum breaker backflow prevention assembly or an approved reduced pressure principle backflow prevention assembly;
(7) In the case of any premises having a fire service line, the public water supply system shall be protected by an approved double detector check valve assembly;
(8) All other premises not covered in divisions (1) through (7) shall be required to install a non-testable dual check valve assembly for the protection of the public water system; and
(9) Existing installations are not exempt from current rules and regulations in this subchapter.
(C) Approval of backflow prevention assembly. Any backflow prevention assembly required herein shall be a model and size approved by the City of Woodburn. The term APPROVED BACKFLOW PREVENTION ASSEMBLY shall mean an assembly that has been manufactured in full conformance with the standards established by the American Water Works Association (AWWA) entitled "AWWA C506-84 Standards for Reduced Pressure Principle and Double Check Valve Backflow Prevention Devices". Said assembly shall meet the laboratory and field performance specifications of the Foundation for Cross-Connection Control and Hydraulic Research (FCCC&HR) of the University of Southern California established by Specifications of Backflow Prevention Assemblies - Section 10 of the most current issue of the Manual of Cross-Connection Control. Final approval shall be evidenced by a Certificate of Approval issued by an approved testing laboratory certifying full compliance with the said AWWA standards and FCCC&HR specifications.
(D) Duty to test and repair. It shall be the duty of the customer/user at any premises where backflow prevention assemblies are installed as referenced within this section under division (B)(1) through (7), to have certified inspections and operational tests made upon installation and at least once per year. In those instances where the City of Woodburn superintendent deems the hazard to be great enough, the superintendent may require certified inspections at more frequent intervals. These inspections and tests shall be at the expense of the water user and shall be performed by a certified tester approved by the State of Indiana. It shall be the duty of the customer to see that these tests are made in a timely manner. If a customer/user does not have its backflow prevention assembly tested within 30 days of the testing due date, the city may discontinue water service to the premises to maintain the safety of the public water system. These assemblies shall be repaired, overhauled or replaced at the expense of the customer/user whenever said assemblies are found to be defective. Records of such tests, repairs and overhaul shall be kept by the customer/user and a copy furnished to the City of Woodburn at: City of Woodburn c/o Utility Superintendent, 22735 Main Street, PO Box 665, Woodburn, IN 46797.

(A) No booster pump shall be installed, taking its suction or supply from the utility’s water distribution system, without the expressed written approval of the utility.
(B) In all booster pump installations, the suction of the pump shall be connected to an atmospheric tank with city water flow entering the tank being controlled by an automatic float valve and discharging freely into the tank two pipe diameters, or a minimum of six inches, above the positive overflow level of the tank.
(C) As an alternate, suitable, control valve limiting suction pressure of the pump to a minimum 20 psig, may be allowed with prior approval by the utility in writing. Proper and continuous operation and maintenance shall be the customers responsibility and expense.
