LightWell uses an ultra-filtration membrane with 0.04 µm (40nm) pore. This pore size is smaller than E coli bacteria (size ranges from 0.5 to 1.5 µm), viruses (size ranges from 0.03 to 0.1 µm), or giardia lamblia, waterborne protozoa (size ranges from 10 to 20 µm).

LightWell is designed with fresh water input, including water from wells, river, spring and rainwater. However, these water sources have different characteristics and, along with other aspects, will cause the rate of filtered water to vary.

Yes, as long as it doesn’t contain the excessive salt and heavy metal. Water clarity is measured by turbidity in NTU (Nephelometric Turbidity Units). It shows how much the material suspended in water decreases the passage of light through the water. Suspended materials include soil particles (clay, silt, and sand), algae, plankton, microbes, and other substances. These impurities are typically in the size range of 0.04mm (40 µm) for clay to 1.00 mm (1000 µm) for sand.
Our ultrafiltration system can reduce turbidity to 0.1 NTU – which means that suspended materials are nearly absent. Importantly, the system exceeds the WHO standards that requires drinking water to have maximum of 5 NTU.

The water ultrafiltration system has a design life of 10 years

30.000 hours – if we assume that the pump works continuously for 8 hours per day, the pump life time exceeds 10 years.

LightWell models use two or three tanks. The top tank stores raw water which provides enough pressure for water to flow by gravity to the filter system.
The bottom tank receives and stores treated water. The middle tank (optional) stores an additional 1000 litres of treated water for immediate access and delivery.
LightWell uses IBC food grade tanks with non transparent-white opaque colour, to ensure safe water delivery.

No, brackish water contains dissolved salt, with the size of less than 1 nm. Our R & D department is considering the development of a new product using reverse osmosis. Please contact LightWell for details.

The solar panels charge the high tech military quality, long-life batteries using intelligent controllers, which give a 10 year system life. The lighting uses the power from the battery.

The lighting capacity depends on the product selection.
Our product lighting selections range from site, public/community hall lighting, distributed to various size village (10 to 100 houses), and a combinations of the above. The requirement defines the number of PV panels to be installed.

LightWell uses LED lights, which are safe and efficient. They have a design life of 50,000 hours, which is equal to 27 years of daily use. The lighting for hall / public areas uses 3 units @30 Watt, and the lighting for houses consists of 2 units, @5.3W.

Lights are designed for easy replacement. Please contact your provider for support if needed.

LightWell is designed in a modular format and built to accommodate growing needs. This means that with any initial choice of LightWell, there is an opportunity to expand its services as required. For example, the basic LightWell only provides lights for a community hall. When the community needs more power, upgrade kits allow incremental expansion.

In an expanded configurations, the PV panels will produce enough energy for lighting and, under certain conditions, 230V AC power. The AC power can be used for variety of charging needs e.g. lamps, phones and power tools. At the higher capacities, the AC power options can power schools and remote medical clinics.
The models are designed in a modular way, in which lighting and power capacities maybe expanded to meet increasing demand.

Most options are available, but some are mutually exclusive, so please create your chosen part number and our engineers will assist you in the optimisation of the model.

We have quality assurance system in place, including establishing long term relationship with our assembly partners and installation contractors. The company has been established for more than 28 years. The water filter and integration system comply to current international standards.

We have a local manufacturing distributor in Jakarta who has twelve branches across the country. We also have another distributor in Fiji, who also covers the countries in the South Pacific. They can be contacted for any technical support required. Alternatively, please contact LightWell International Ltd.

Light*WELL is designed in a modular format and built to accommodate growing need. If finance situation permits, LW capacity can be increased. For example, the basic Light*Well produces minimum 1200 liters per day, and additional filters can be added to increase the flowrate of filtered water to a minimum of 3600 liters per day.

The distributor will be able to help you.

The interface board will display messages for normal operation (green light), early warning (yellow light) or warning (red light) in which actions are needed.
