HomeMy WebLinkAboutA002 - Memo from City Attorney to Building Official, revisions to plumbing regulations Memo City Attorney's Office Caring People Quality Programs Exceptional Service TO: Jeff Pearson, Building Official FROM: John R. Klaus, City Attorneq*q/x DATE: September 1, 1998 SUBJECT: Revisions to Plumbing Regulations With this is another draft of an ordinance to adopt portions of the 1997 edition of the Uniform Plumbing Code and to make other requested additions and changes to the plumbing regulations of Ames. The draft is in two forms. One form is called a"red-line" draft. It shows the new provisions added as shaded,and old material deleted by strikeouts. The other form is the net product of the proposed adds and strikeouts and is what the Mayor and Clerk will sign and publish when passed. It is my hope that when you submit this matter to the City Council with your Council Action Form you will also send out the"red line" draft so it will be easy to explain what is being changed. Section 380.10, Code of Iowa, states the procedure by which a City may adopt all or parts of a statewide or nationally recognized standard code. The Council is required to hold a public hearing for which notice is published at least once, not less than four nor more than 20 days before the hearing. The notice must state that the codes adopted are on file with the Clerk and available for inspection. If the Council "substantially' amends the proposed Code after the hearing, the notice and hearing must be done over. Also, if the Council fails to pass the ordinance within 30 days after the hearing, the process has to start over. Before submitted to the Council, we will need to have some nice renderings of the two illustrations you want for Subsection 21.702(2) and(3) respectively.

The purpose of these cross-connection control regulations is: (i) to protect the City of Ames Public Water Supply (PWS) from the possibility of contamination or pollution through cross-connections by isolating within the customer's internal distribution system(s)or the customer's private water system(s)such contaminants or pollutants that could backflow into the PWS;and (ii) to provide for the maintenance of a continuing program of cross-connection control Sup#8/1995 CODE 21-12 Rev. 7-1-97 that will systematically and effectively prevent the contamination or pollution of the PWS. (b) Definitions (i) Approved Backfiow Prevention Assembly For Containment. A backflow prevention assembly which is listed by the University of Southern California-Foundation for Cross-Connection Control and Hydraulic Research as having met the requirements of ANSI-AWWA Standard C510-92,"Double Check Valve Backflow-Prevention Assemblies",or ANSI-AWWA Standard C511-92, "Reduced-Pressure Principle Backflow Prevention Assemblies"for containment. The backflow prevention assembly must also be listed by the International Association of Plumbing and Mechanical Officials. (ii) Auxiliary Water Supply. Any water supply on or available to the premises other than the PWS. These auxiliary waters may include used waters;industrial fluids;or water from another purveyor's public potable water supply or any water source(s)such as a well,spring,river,stream,and so forth. (iii) Backfiow. The undesirable reversal of flow into the public water distribution system as a result of a cross-connection. (iv) Backfiow Prevention Assembly. An assembly or means to prevent backflow. a. Air Gap. This is a physical break between the PWS and the customer's water system. The air gap is to create an unobstructed vertical distance between the opening of any pipe or faucet conveying water to a tank,plumbing fixture,receptor,or other assembly and the flood level of the receptacle. These vertical separations must be at least twice the diameter of the water supply outlet,never less than one-inch separation. b. Reduced-Pressure Principle Backfiow Prevention Assembly(RP). The RP consists of two independently acting check valves together with a hydraulically operating,mechanically independent pressure differential relief valve located between the check valves. These units are located between two tightly closing resilient-seated valves as an assembly and equipped with properly located resilient-seated test shutoffs. C. Double Check Valve Assembly(DC). The DC consists of two internally loaded check valves,either spring loaded or internally weighted,installed as a unit between two tightly closing resilient- seated shutoff valves with properly located resilient-seated test shutoffs. (v) Containment. A method of backflow prevention which requires the installation of a backfiow prevention assembly at the water service connection. (vi) Contamination. An impairment of a potable water supply by the introduction or admission of any foreign substance that degrades the quality of the water and creates a health hazard. (vii) Cross-Connection. An actual or potential connection between any part of a potable water system and any other environment containing other substances in a manner that,under any circumstances,would allow such substances to enter the potable water system. (viii) Cross-Connection-Controlled. A connection between a potable water system and a non-potable 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. (ix) Hazard,Degree of The rating of a cross-connection or water service which indicates if it has the potential to cause contamination or pollution. The term is derived from an evaluation of the potential risk to public health and the adverse effect of the hazard upon the potable water system. a. Hazard-Health. A hazard upon the PWS involving any substance that,if introduced in the potable water supply,could cause death,illness,spread disease,or have a high probability of causing such effects. b. Hazard-Non-health. A hazard upon the PWS involving any substance that generally would not be a health hazard but,if introduced into the PWS,could cause a nuisance by introducing color,taste, odor,and so forth,or physically,chemically,or biologically alter the quality of the PWS. (x) Industrial Fluids System. Any system containing a fluid or solution that may contaminate or pollute the PWS. This may include,but not be limited to polluted or contaminated waters,all types of process waters and used waters originating from the public potable water system,chemicals,acids,alkalies,cooling waters,oils, gases,and so forth. (xi) Pollution. The presence of any foreign substance in water that impairs, alters, or degrades its quality but does not constitute a health hazard. (xii) Registered Backfiow Prevention Assembly Technician(Technician). A person who Sup#8/1995 CODE 21-13 Rev. 7-1-97 is registered by the State of Iowa to test or repair backflow prevention assemblies and report on the condition of those assemblies. (xiii) Service Connection. The terminal end of a service connection from the PWS;that is, the point of delivery to the customer's water system. If a meter is installed at the end of the service connection,then the service connection shall mean the downstream end of the meter. Service connections shall also include water service connection from a fire hydrant and all other temporary or emergency water service connections from the public water system. (xiv) Thermal Expansion. Volumetric increase of water due to heating resulting in increased pressure in a closed system. (xv) Water-Potable. For the purposes of these regulations,potable water is the City of Ames public water supply while it is under the city's control and jurisdiction. (xvi) Water - Non-potable. Water that is not safe for human consumption or that is of questionable or unknown quality. (xvii) Water-Used. Water supplied by the PWS to a customer after it has passed through the service connection. (c) Administrative Authority (i) The administrative authority is the Ames City Council acting through such persons or departments the City Council shall designate. (ii) The administrative authority shall have the right to enter, with the consent of the customer or upon the basis of a suitable warrant issued by a court of appropriate jurisdiction,any property to inspect for possible cross-connections. a. All backflow prevention assemblies shall be available for city inspection within a short notice by the administrative authority. Short notice is considered to be less than 24 hours. b.

Premises having(1)internal cross-connections that cannot be permanently corrected and controlled,(2)intricate plumbing and piping arrangements or where entry to all portions of the premises is not readily accessible for inspection purposes, making it impractical or impossible to ascertain whether or not cross- connections exist d. At premises having more than one water service,not including fire protection systems,all service connections shall be protected against backflow from the premises by installing an approved backflow prevention assembly for containment at each service connection (ii) Failure of the administrative authority to notify a customer that they are believed to have a health hazard cross-connection and that they shall install backflow prevention assemblies for containment shall in no way relieve a customer of the responsibility to comply with all requirements of these regulations. (e). Type Of Containment Required (i) The PWS shall be protected by an RP or an air gap separation a. where there is an auxiliary water supply; b. where there is any material dangerous to health that is handled in such a fashion as to create an actual or potential hazard to the PWS; Sup#8/1995 CODE 21-14 Rev. 7-1-97 C. where there are"uncontrolled"cross connections,either actual or potential; or d. where,because of security requirements or other prohibitions or restrictions, it is impossible or impractical to make a complete in-plant cross-connection survey. (ii) The PWS shall be protected by a DC where there is water or other substance that would be objectionable but not hazardous to health if introduced into the PWS. An air gap separation or an RP may be used in lieu of a DC. (iii) The PWS shall be protected by a DC where there is more than one water service connection. An air gap separation or an RP may be used in lieu of a DC. Use of a DC will not be permitted if there are other conditions present which require an air gap separation or an RP. (iv) The director of the City of Ames Water and Pollution Control Department may require installation of an air gap separation,by and at the customer's sole expense,at the service connection where records indicate a history of threat to the public water supply system because of negligence in handling health hazard substances or actual backflow into the PWS. (f). New Water Services (i) Plans shall be submitted to the administrative authority for review on all new water services in order to determine the type of containment needed. (ii) The administrative authority shall require the installation of the appropriate backflow prevention assembly for containment before the initiation of water service.
