The Public Service Authority is hereby authorized to adopt a cross-connection control program in accordance with this article and the Waterworks Regulations of the Virginia Department of Health. The Director of the Public Service Authority or his designated agent shall, in accordance with the Public Service Authority's duly adopted cross-connection control program, inspect the plumbing in every building or premises served by the Public Service Authority waterworks system as frequently as may be necessary to ensure that such plumbing has been installed and is maintained in a manner as to prevent the possibility of pollution or contamination of the public water supply. The Director shall notify, or cause to be notified in writing, the owner, occupant or authorized agent of the owner of any such building or premises to correct, within a reasonable time set by the Director, any plumbing installed or existing contrary to or in violation of this article and which may create the risk of pollution to the County water supply or otherwise adversely affect the public health.
A. 
The Director or his designated agent shall inspect all premises or buildings during reasonable hours and under such circumstances as to minimize the inconvenience to the owner or occupants of the premises or their agents. Should any owner, occupant or agent refuse to allow the Director access to the premises for the purposes of conducting an inspection, or should the Director not be able to contact the owner, occupant or agent for the purposes of obtaining permission to inspect, the Director shall have the right to apply immediately to a Magistrate or other judicial officer for a proper warrant to carry out the necessary inspection. The provisions of this section shall apply to all initial inspections and to such follow-up inspections as may be necessary.
B. 
Termination of water.
(1) 
In addition to the warrant procedure set forth in Subsection A of this section, the Director may commence administrative proceedings to discontinue water service to the uninspected premises. Except in emergency cases involving the imminent risk of pollution of the County water supply, the Director shall give 10 days' written notice to the owner or occupant of the affected premises, or to a responsible agent, of the Director's intention to terminate the water service. The Director shall afford to the owner, occupant or agent a hearing on the question of whether water service shall be terminated. This hearing shall be scheduled and conducted in such a manner that, to the maximum extent feasible, the inconvenience and burden on the owner, occupant or agent shall be minimized. The hearing shall take place before the Director or a designated principal assistant. The Director shall not terminate the water service to the premises in question, if it is found as a fact that:
(a) 
The owner, occupant or agent has presented clear, convincing and credible evidence that there are no cross-connection hazards within the subject premises; and
(b) 
No purpose of this article would be served by conducting an on-site inspection of the premises.
(2) 
In all cases, the hearing provided by this subsection shall be scheduled within the ten-day period immediately following the giving of written notice to the owner, occupant or agent. Upon a showing of good cause, the Director may grant a reasonable continuance of the hearing so scheduled, but the Director, nevertheless, shall retain the right to terminate the water service at the expiration of the ten-day notice period if, in his discretion, public health considerations require such action. The Director shall, in all cases, render his decision immediately after the taking of all evidence at the hearing, or as soon thereafter as may be practicable, but in no case later than 24 hours following the termination of the taking of evidence. The Director shall cause his findings of fact and disposition of the case to be reduced to writing and shall preserve the same for a period of one year.
C. 
In emergency circumstances where the Director has reasonable cause to believe that a cross-connection hazard exists in the subject premises and that such hazard jeopardizes the integrity or the purity of the County water supply, he shall forthwith terminate the water service to the subject premises. The Director shall thereafter immediately afford the owner, occupant or agent the notice and opportunity to be heard pursuant to the procedures set forth in Subsection B of this section. In all cases where the Director shall summarily terminate water service, as provided under this subsection, the Director shall act with dispatch in notifying the owner, occupant or agent and shall exercise the utmost diligence in scheduling a prompt hearing on the matter.
D. 
Notwithstanding the provisions of Subsections A and B of this section, the Director shall not terminate any water service in cases where the Director has reliable information from any sources indicating that cross-connection hazards do not exist on the premises to which access for inspection cannot be gained.
A. 
The cross-connection hazard and backflow-prevention devices required shall be as set forth in the chart included as an attachment to this chapter.
[Amended 11-14-2013]
B. 
When investigation discloses that unusual or extraordinary hazards require more stringent means of protection, the Director shall have the authority to require the installation of the same. The Director shall in all cases specify the facts constituting the greater hazard found to require more stringent protective measures. The more stringent protective measures shall be related to such unusual or extraordinary hazards and shall be no more burdensome than is reasonably necessary to alleviate or guard against such hazards. The Director shall specify in writing to the owner the manner in which the more stringent protective measures alleviate or guard against the unusual or extraordinary hazards.
Cross-connection between approved potable community or noncommunity water systems and other unapproved systems or equipment containing water or other substances of unknown or questionable safety are prohibited, except when and where, as approved by the Director, protective devices such as the reduced-pressure-zone backflow preventer or its equivalent are installed, maintained and tested to ensure proper operation on a continuing basis. The Director of the PSA may deny or discontinue the water service to a consumer if the required backflow-prevention device is not installed. If it is found that the device(s) has been removed or bypassed or if a cross-connection exists on the premises, or if the pressure in the waterworks is lowered below 10 pounds per square inch gauge, the Director shall take positive action to insure that the waterworks is adequately protected at all times. Water service to such premises shall not be restored until the deficiencies have been corrected or eliminated in accordance with the Commonwealth of Virginia Waterworks Regulations and to the satisfaction of the Director.
