INTERSTATE SAFETY REST AREA FACILITIES PROVIDE UNUSUAL WATER USE DEMANDS. THE DESIGN OF WATER SYSTEM ELEMENTS CAN BE BASED ON THE PEAK INSTANTANEOUS, MAXIMUM HOURLY, AND MAXIMUM DAILY WATER DEMAND RATES. THE PEAK INSTANTANEOUS DEMAND RATE ESTABLISHES THE REQUIRED PIPE SIZES AND THE CAPACITY OF ELEMENTS SUCH AS THE PUMPS TO THE HYDRO-PNEUMATIC TANKS. THE WATER SOURCE CAPACITY SHOULD BE EQUAL TO THE MAXIMUM DAILY WATER USE RATE WHILE THE REQUIRED STORAGE VOLUMES ARE DETERMINED BY THE MAXIMUM HOURLY USE RATE. WATER AVAILABLE FROM NATURAL SOURCES SUCH AS WELLS IS NOT PURE. NUMEROUS TYPES AND CONCENTRATIONS OF IMPURITIES PRESENT IN THE WATER SUPPLY WILL INFLUENCE THE SUITABILITY OF THE SOURCE. THE NEED FOR BACTERIOLOGICALLY SAFE WATER IS OBVIOUS. OTHER CONSTITUENTS AND CHARACTERISTICS, SUCH AS IRON, MANGANESE, SULFATES, CHLORIDES, NITRATES, AND HARDNESS, MUST BE CONSIDERED IN SELECTION OF A WATER SOURCE. THE ADEQUACY OF THE AVAILABLE WATER QUANTITY AND WATER QUALITY MUST BE CONSIDERED IN THE EARLY PLANNING AND DEVELOPMENT OF THE SAFETY REST AREA FACILITIES. THE SUCCESSFUL OPERATION AND MAINTENANCE OF NUMEROUS REST AREA FACILITIES THROUGHOUT EACH STATE WILL DEPEND TO A GREAT EXTENT ON THE STANDARDIZATION OF THE WATER SYSTEMS. THIS DESIGN APPROACH WILL BE PARTICULARLY ADAPTABLE TO THE HYDRAULIC ELEMENTS AND IS ALSO APPLICABLE TO MANY OF THE TREATMENT ELEMENTS OF THE WATER SYSTEM. /AUTHOR/
