Refer to applicable technical manual for equipment and performance data on the 125 GPM pumping assembly. 1.17.4 Hypochlorination Units . Refer to applicable technical manual for equipment and performance data on model 1955-3. Refer to applicable technical manual for equipment and performance data on model A-506131. The equipment and performance data for model 1955-1 is detailed below. Weight 166 lb (75 kg) Length 26 inches (66 cm) Width 18 inches (45 cm) Height 28 inches (71 cm) Flow 100 gpm maximum 2 gpm minimum Ambient Temperature Range 350 to 1300 F (1.70 to 54.4° C) Range 10:1 Hypochlorinator Feed Rate 55 gpm Reservoir Container Capacity 5 gal (19 L) Inlet and Outlet Pipe Size 2 inch female pipe thread 1.18 EQUIPMENT CONFIGURATION . The TWDS can be deployed in multiple configurations. The configurations are dependent on the application of the TWDS and the terrain over which the system is deployed. When the TWDS is deployed over smooth terrain five pumping stations are required. When the TWDS is deployed over rough terrain six pumping stations are required. During rough terrain deployment if there is a decrease in elevation of 75 feet or greater between two pumping stations a pressure-reducing valve assembly can be installed in the main hose line to reduce water pressure and protect down line equipment from damage. When the TWDS is deployed for transporting water from a source to a large storage or distribution unit, only the pumping stations and 10- mile hose line segment are required. For water distribution to personnel or storage three configurations can be employed. First, one storage assembly and distribution point can be installed in the TWDS. Second, two storage assemblies and distribution points can be installed in the TWDS. Third, if only transporting and water storage capabilities are required, the TWDS can be deployed without the distribution points. SECTION III. PRINCIPLES OF OPERATION 1.19 FUNCTIONAL DESCRIPTION . The TWDS is used to transport potable water across level terrain for distances up to 10 miles. Five or six pumping assemblies are used to transport water from a source, desalination units, wells, or large storage and distribution units, to two 20,000 gallon storage assemblies, additional TWDS units, or larger storage and distribution units. The water stored in the two 20,000 gallon pillow tanks can be supplied to large storage or distribution units or can be chlorinated and dispensed to personnel through two distribution points. A functional description of each functional unit comprising the TWDS is provided in the following paragraphs. 1.19.1 Pumping Stations. There are two different types of pumping stations required for the TWDS. Each pumping station consists of a trailer mounted pumping assembly, a check valve, three 6 inch butterfly valves, various 6 inch hose assemblies as detailed below. The pump assembly is powered by a 6 cylinder diesel engine. Pump operation is controlled through a control panel mounted on the pump assembly. Refer to applicable technical manual for a complete functional description of the 600 GPM pumping assembly. A functional description of each type of pumping station is provided below. 1-15
