Set Up, Tear Down and Operating Requirements

After all components or modules have been positioned at the site of use, assuming only Mode 1 of operations, just the LS3 component of the WPS UNIT, the system can be put into operation by one personnel. If only the LS3 subsystem mode is being used, the setup time would be less than 1 hour (usually under 30 minutes). If using a sea water source or if NBC contamination is present and the RO subsystem mode is being used, the setup time would be within one hour and require two personnel. Set up time includes performing all pre-operation checks and services, establishing initial settings, making all mechanical or electrical connections, installing expendable items or supplies, making adjustments, and adding fluids or chemicals. Preparing the WPS UNIT for shipment or movement to another site takes one to two personnel no longer than 1 hour from the time of notification. Operations are geared for one person to operate.

Fuel and Power Interfaces

Diesel generators are preferred and can be placed on the operating platforms.

Procedures and Tools

Tools are standard SAE (all English) and the number of tools required to repair or maintain the systems are kept to a minimum. Operator level maintenance consists of preventive maintenance checks and services and modular replacement of defective assemblies. All tools required for normal operations and routine operator maintenance should be stored with each Global unit for protection, accessibility and transport.

Operation Time Meters

The RO component has a meter that indicates to the operator the number of hours that the unit has been operated. The meter shall use the operational hours of the high pressure pump as the basis for the RO component system operational hours. The LS3 component has its own rate and flow metering.

System Durability and Ruggedness

The WPS UNIT is rugged and durable to prevent, other than normal wear and tear, damage during repetitive transport, handling, lifting and loading/unloading, set-up, tear down, and operating cycles by personnel in a field environment. Global's current equipment has been field tested through the roughest of terrain, dropped from helicopters, and dropped from the back of trucks with minimal problems. They hold up just fine, and after years of use, they keep on working.


To promote and assist the achievement of maintainability objectives, Global Water will ensure the ability to maintain the equipment in the field. The capability of the potential operators to affect necessary repairs on-site is also an integral part of our design philosophy. Integral to these is the capability of the operator to quickly identify and correct any malfunction in the most adverse conditions to which the system is exposed.

In achieving the above objectives Global's operations, maintenance, and parts manuals are written in concise language. Technical terms are used only when absolutely necessary and are followed by definition. The use of drawings and pictures to compliment written text and promote understanding are maximized. The objective of the manuals is to provide the tools which an individual, who has no prior knowledge of the unit, can use to learn to operate and maintain the unit in a minimum amount of time.

Global will define:

  • Periodic maintenance requirements are those tasks which must be performed on calendar and/or hourly intervals.
  • Conditional task are performed when a given condition is met.
  • Unscheduled component replacement occurs when a component fails and must be replaced.


The design of ruggedly built reliable water purification units has been a major part of the design and manufacturing philosophy since the inception of Global Water Technologies. In many instances our current production models are deployed and utilized in areas that are remote and isolated where the availability of spare parts is non-existent. Many of our units are used in disaster relief efforts and are frequently the sole source of clean drinking water in the immediate area. As a result, users of equipment expect to not only produce safe drinking water but to do so day after day. Global Water Technologies takes pride in its ability to produce highly dependable water processing units. We also recognize that, with age and use, equipment will malfunction regardless of the amount of depth of a preventive maintenance program. We have therefore focused our efforts on developing and maintaining simplicity in unit design and construction, simplicity in operator-machine interface, and simplicity and ease of maintainability. These concepts have enable user personnel to rapidly gain the knowledge, skills, and experience required to operate and maintain the LS3 units in the field. The capability of field personnel to quickly complete on-site repairs and return the units to full operating status has significantly contributed to the reputation of the equipment and the company.

Based on unit design, all primary, secondary, and support systems are identified. A preliminary Bill of Material (BOM) is then prepared for each of the systems. The BOM identifies every component and item, including common hardware, which is required for each individual system.

The identification of all primary and secondary systems every components within the systems are also identified.

Required operating parameters are established for each component based on function and critical importance to system and unit performance.

Material and components are researched and purchased based on the ability to meet or exceed the criteria established above. Every model now produced by Global Water Technologies exceeds original design criteria.

Critical manufacturing tasks are identified. These are tasks, which if not performed correctly, could/would cause premature failure of a component or unit.

Quality assurance inspection requirements are established with special attention placed on critical manufacturing tasks.

Every unit currently produced by Global Water Technologies must meet stringent test criteria established for systems and components in each unit to ensure that that not only the components but also the system meets the criteria for water purification equipment as required by local, state, and federal regulations. The test criteria apply to all system modes of operations and functions. Currently all production units manufactured by Global Water undergo a minimum of 25 hours of test and operation prior to shipment to ensure that the unit is ready for use when received by the customer.

Use of Corrosion Resistant Materials and Suitability for Field Conditions

Global military equipment is designed to be simple to use, easy to maintain, rugged and reliable. All Military models constructed by Global Water Technologies takes into consideration the tough operational environment of military training and operation. The WPS system follows the same tough standards, making it resistant to moisture, corrosion, oxidation and growth of fungus and bacteria. All the electrical connections are protected. All material that could be corroded is made of corrosion resistant material. They have been field proven in combat and have been used by the US military in Somalia, Rwanda, Haiti, Afghanistan, Iraq and Bosnia.

Nuclear Biological Chemical (NBC) Survivability (optional features)

These systems can be equipped with an optical spectrometer, a nephelometer, conductimeter and thermometer to determine, turbidity, TDS and temperature of source water. Data will automatically select the components to be used for the particular water type being processed. The output water from the RO and the LS3 components are then monitored for TDS, turbidity, temperature, and flow rate. The data is digitally displayed, digitally recorded and graphed. If the output water is below established minimums, the component will disconnect the system. The system is configured to withstand NBC contamination and decontamination. LS3-DESAL Series are designed to reduce corners and lips that can retain contaminants. Materials and assembly will tolerate water pressure, detergents and alkaline solutions. After the decontamination, the system will resume normal operation producing potable water of US Tri-Service quality Standards as originally designed. Following an NBC attack, there is a procedure set to replace all filters, filter housings, multi-media pods and hoses. All processed water will now be potable. Initial start-up clean output is used to wash down the equipment (with cleansing solvents) to decontaminate the system. Control panels have been modified for NBC survivability specifications whereby the operator, can easily activate and service the system wearing heavy, bulky gloves, and protective gear.

Note: See Military Catalogue for details on all products

All of Global's systems (unless stated as DESAL [Desalination], High TDS, or Brackish) assume fresh water or low TDS source water. Sources of water might be municipal systems, rivers, lakes, ponds or wells. Water Filtration System: Unit filters out harmful bacteria and parasites using replaceable filter media. This prepares water for consumption by persons without access to safe water supplies.

Systems are mobile and self-contained. They can be ordered as fixed base systems. All systems have a one year limited warranty. There are options for ALL WEATHER HOUSINGS, trailers, NBC capability and Extended (3-Year) Warranties.
