The following rules, regulations and orders made by the Board of Trustees of the Village of Elmsford, acting as a Board of Water Commissioners in the Village of Elmsford, relative to water obtained from or supplied by the municipal system of the Village of Elmsford, shall become operative only upon proclamation by the Mayor of the Village of Elmsford that a public emergency exists with respect to water usage and consumption and shall continue until further notice and order of the Mayor:
A. 
The washing of automobiles by hose is prohibited. The use of Village water for car washing in commercial establishments is prohibited, except where automatic or semiautomatic car-washing equipment is employed, and where at least 50% of the water is reused by means of a sump recirculating system, so that Village water is used only for the final rinse.
B. 
Garages, automobile service stations and other similar establishments which furnish car washing as part of their regular service and are not equipped with automatic or semiautomatic car-washing equipment mentioned above, may only use a bucket of water for this purpose.
C. 
The cleaning or washing of the outside of buildings or any structures, involving the use of water or steam in any form, is prohibited.
D. 
No water supply lines shall be maintained with bleeds on any structure or in any building for the purpose of maintaining a constant flow of water.
E. 
No swimming pools shall be operated, except such swimming pools as have automatic filtering and regulating devices that will not require any additional water for operation. Replacement of water by Village water supply is prohibited.
F. 
No automatic plumbing flush fixtures or apparatus using a constant or fixed periodic flow shall be maintained or operated. The flow from such apparatus shall only be by individual operation when the fixture or apparatus is in actual use.
G. 
The use of hose, spout and similar pressure bathing apparatus is prohibited, and no constant flow from showers or similar apparatus shall be maintained. Operation of such apparatus shall be individual, and only when the apparatus is in actual use.

I. 
Applications for permits for refrigeration and/or air conditioning to be installed shall specify the information requested on the application. An approved copy of the application shall be returned to serve as the permit.

All installations of any individual or collective system of refrigeration and/or air-conditioning equipment in any premises for a single consumer shall be installed under the following specifications:
(1) 
All installations of any individual or collective system of refrigeration and/or air-conditioning equipment of three tons and over shall be equipped with a water-conserving device such as economizer, evaporative condenser, water-cooling tower or similar apparatus, which device shall not consume for makeup purposes in excess of 5% of the consumption that would normally be used without such device.
(2) 
All new installations of refrigeration and/or air-conditioning equipment under three tons, and all existing equipment of all sizes not using recirculated water, shall be provided with an automatic water supply regulating device so as to limit the flow of water in relation to the condenser temperature reduction requirements of the apparatus. In no case shall the equipment use in excess of two gallons per minute per ton capacity.
K. 
Each direct water connection to a refrigerating and/or air-conditioning unit using water for cooling purposes shall be equipped with a check valve, except in installations where the water supply piping has no contact with the refrigerant. This will be the case where two substantial and independent wall thicknesses of metal separate the refrigerant from the Village water supply.
L.
