FAQs

The primary source of power is renewable solar energy. There are no harmful or hazardous chemicals used in the filtration process. When the adsorption media has been exhausted and needs to be changed, the spent adsorption media is safe enough to discharge in a regular landfill without special handling.

Our robust system eliminates the need for constant shipments and deliveries of consumable cartridge filters every few weeks, this eliminates the need to manufacture, pack, ship, drive, and burn hydrocarbons to deliver those never ending supplies. All of those exhausted cartridge filters need to be disposed of as well. The least amount of waste involved in any product is a good thing and also good for the earth. GPRM’s design is so well engineered that it does not require home system based disposable cartridge filters. Our extensive experience in the field has helped us understand the water purification needs in the world’s most remote and harshest environments. In times of an international crisis a frequent solution to a clean water shortage is to air freight thousands of gallons of bottled water to affected areas. The estimated fully burdened costs exceed $400,000 per planeload and this does not include the significant carbon footprint generated to load a C17 cargo plane with bottled water, pay for the pilot, loadmaster, crew, and fuel, on your way to your destination with a maximum of 19,161 gallons of water on board. The amount of trash from all of those consumed plastic bottles cannot be ignored either. One of our systems on the ground in that very same location can generate much more than 25,000 gallons of fresh drinking water EVERY DAY with no need for constant C17 plane trips or massive piles of plastic bottles littering the landscape.

The units are engineered and capable of safely producing up to 50,000 gallons per day of fresh drinking with any combination of solar, generator, or existing municipal water pressure

The unit is capable of producing drinking water free of physical and bacteriological contaminations. The unit will not take care of industrial contamination, such as hydrocarbons, chemical waste, etc.

The user can monitor the pressure gauges on the unit to determine if any backwashing may be required, UV lamps should be replaced yearly. The solar panels should be kept as clean as possible.

UV lamps should be replaced yearly and adsorption media every 3-5 years (or longer. Amortized over a yearly basis is less than 1% of system cost.

The adsorption media is long lasting and can be backwashed to remove particulates when necessary. Depending upon the water quality the adsorption media can last from 3-5 years (or longer) before needing to be replaced. The bacteriological filter cartridges can be easily cleaned in the field by pressure steam cleaning or cleaning with a chlorine solution.

Both units are forklift ready, both units have helicopter lift points, and the mobile unit can be placed on a trailer or truck bed for easy transport.

Our skid-mounted mobile unit weighs 2,250 lbs and is 8’L x 4’W x 6’H, (2.5m x 1.2m x 1.8m). The Tricon container unit weighs 5,200lbs and is housed in a secure and self contained 8’L x 6.5’W x 8’H (2.5m x 1.2m x 2.5m) shipping container.

Site preparation is simple. All the system requires is a level area to place the unit that has good site lines to the sun as it travels thru the sky during the day, and a water source within 60′ (30m) nearby.

The filtration unit uses one 12 volt, maintenance free, sealed gel battery.

The battery is only used to power the UV filtration lights. Battery life will depend on many factors but a typical battery will last around 5 years if properly charged and cared for.

For locations north of the equator the solar panels should be angled towards the south, for location south of the equator the solar panels should be angled towards the north. No solar tracking devices are necessary. GPRM recommends that manually adjusting the panels is the most practical method for sun tracking when in the field.

No, the unit comes with everything needed to begin operating immediately. A small toolkit, spare UV bulbs, and misc spare parts are shipped with each unit.
