No consumer may install or maintain any cross-connection from any auxiliary supply. If such cross-connection exists, service will be terminated to prevent contamination of the water supply. The consumer must disconnect the auxiliary supply before resuming water service from the village water system. Where required by the New York State Department of Health Sanitary Code or by the Superintendent, a backflow prevention device of a type currently approved by the New York State Department of Health must be installed.
On any premises where a backflow prevention device exists, the consumer must conduct an inspection of said device at least annually and at any time directed by the Superintendent. The consumer must pay the cost of installation, repair or replacement. Testing must be performed by a registered installer, and all test results must be provided to the Superintendent within 72 hours of the test. Records of such tests, repairs or replacements must be kept and made available to the Superintendent and the Wyoming County Health Department.
The Superintendent may order the installation of separate drinking water systems at points convenient for consumers.
Water for fighting fire obtained from an auxiliary supply must be kept separate from drinking water pipelines and equipment. When water is used for both drinking and fire-fighting purposes, approved backflow prevention devices must be installed to protect such individual drinking waterlines as are not used for fire-fighting purposes. Any auxiliary supply which is so connected that it may be introduced into potable water piping during an emergency must be equipped with an approved automatic chlorination machine. The person causing the introduction of said unapproved or unsafe water into the pipelines must develop and execute a procedure to notify and protect users of the water system during the emergency and must take special precautions to thoroughly disinfect and flush out all pipelines which may become contaminated before they are again used to furnish drinking water.
Potable water pipelines connected to equipment for industrial processes or operations must be protected by a suitable backflow prevention device located beyond the last point from which drinking water may be taken, which device must be provided on the feed line to process piping or equipment. In the event that the particular process liquid is especially corrosive or apt to prevent reliable action of the backflow prevention device, air-gap separation must be provided.
Sewage pumps must not have priming connections directly off any drinking water systems. No connections may exist between the drinking water system and any other piping, equipment or tank in any sewage treatment plant or sewage pumping station.
Where premises contain more than one water system (either village or private), the exposed portions of pipelines must be painted, banded or marked at sufficient intervals to distinguish clearly which water is safe and which is not. All outlets must be properly marked as being unsafe or safe for drinking purposes. A water supervisor must be designated who will be responsible for the installation and use of pipelines and equipment and for the avoidance of cross-connections. In the event of contamination or pollution of the drinking water system due to a cross-connection on the premises, the Superintendent and Wyoming County Health Department must be promptly notified.
No water service may be installed or maintained unless the water supply is protected as required by state regulations and this Article.
Service to any premises may be terminated if a backflow prevention device required by this Article is not installed, tested and maintained; if any defect is found in an installed backflow prevention device; if a backflow prevention device has been removed or bypassed; or, if unprotected cross-connections exist on the premises. Service will not be restored until such conditions or defects are corrected.
