THIS TECHNICAL PROPOSAL PRESENTS A LIGHT-WEIGHT MANUALLY INSTALLED RAW WATER INTAKE TO BE USED IN OPERATION WITH TRANSPORTABLE MILITARY WATER PURIFICTION UNITS WHEN SOURCE WATER IS OBTAINED FROM OCEAN SURFSIDE LOCATIONS.

THIS TECHNICAL PROPOSAL PRESENTS A LIGHT-WEIGHT MANUALLY INSTALLED RAW WATER INTAKE TO BE USED IN OPERATION WITH TRANSPORTABLE MILITARY WATER PURIFICTION UNITS WHEN SOURCE WATER IS OBTAINED FROM OCEAN SURFSIDE LOCATIONS. THE RAW WATER INTAKE SHALL MAKE USE OF SPECIAL NON-CLOGGING HIGH CAPACITY SUBMERSIBLE PUMPS THAT CAN HANDLE DEBRIS AND SAND WITHOUT DAMAGE. SAND EJECTORS, WATER JETS, VERTICAL PRESSURE AND ROTATION WILL BE USED TO DEVELOP A PROTECTED SHALLOW SEASIDE TYPE WELL. THE PROPOSED SBIR PHASE I RESEARCH WILL BE CARRIED ON IN TWO PARTS. PART I WILL INCLUDE HYDRAULIC STUDIES IN THE LABORATORY, PRELIMINARY SEAWATER PERMEATION MEASUREMENTS FROM SMALL DIAMETER CORES AT AN OCEAN SITE AND EXPLORATORY TESTING OF THE PRINCIPAL COMPONENTS OF THE "SWINFRO" AT AN OCEAN SITE. THE INFORMATION COLLECTED IN PART I WILL BE USED TO DEVELOP CONCEPTUAL DESIGN OF A SEAWATER INTAKE TO SUPPORT THE 600 GPH ROWPU. PART II OF PHASE I WILL INCLUDE PREPARATION OF EQUIPMENT DESIGN DRAWINGS, OF A PROTOTYPE "SWINFRO" MODEL FOR THE 600 GPH ROWPU.
