Mobile Water Box
A water hotspot / water kiosk / mobile water box (water treatment and delivery point) is usually connected to one or more wells (groundwater).
With central water dispensers, up to 10,000 people per box can be safely and efficiently supplied daily thanks to our safety concept. They are quickly set up and can be put into operation within a few hours. The water is released via an intelligent recognition and payment system. For this, every consumer gets a "water card" similar to credit cards or mobile payment system.
In the cost / benefit comparison to water transport to wheels (trucks, tankers) or a piping system, a water hotspot performs far better. Another advantage is that the water can be distributed fairly. In times of need (dry season), the water requirement can be reduced in the worst case for individual consumers and users and delivered in smaller daily quantities. The water prices are thus not raised even in drought.
The mobile solution was invented by Swiss inventor Adrian Zwahlen. The years of experience in the construction of small hydropower plants helped. When finding a solution, the goal was to bring to market a flexible, robust and compact system that can be built on its own.
With our focus on underserved developing countries, there is another problem. Due to the lack of waste recycling infrastructure this is disposed of in rivers and lakes. This pollutes the water. Unfortunately, hundreds of thousands of people depend on it - to fall ill and die. That's why we chose a drilling solution. Here the earth with its different geological layers acts like a filter and a good prefiltration is done by nature. Then we clean again with coarse filters, pre-filters, carbon filters and finally UV light and chlorine to eliminate even the last bacteria and viruses.
After receiving the permit, the well drilling will be carried out with installation of the technical installations according to our specifications. This work is carried out under the supervision of CWC. The well construction and equipment is carried out according to DVGW (German Association of Gas and Water). Several laboratory tests of the collected water determine the technical development of the treatment plant.
In order to raise the water quality to set standards an extensive cleaning system is necessary (example picture from the inner life of a mobile water box you see next door).
We purify the water with the following methods
- Pre-filtration through rocks, as we draw exclusively groundwater.
- carbon filtration
- UV light
Installation of the water treatment plant
Already during the well drilling, the predetermined area is surrounded by a strong fence. At the same time, the necessary foundations for the 20-foot container and water reservoir, including digging work for the water supply and electrical connection, are created (alternatively, the system can be operated with solar energy). After the successful well drilling, the container is delivered and firmly connected to the concrete foundations. The container contains the fully assembled and tested water treatment plant. The water and electric cables, GSM module are coupled and connected in the container at the designated locations. The system can now be put into operation.
Sideways on the container are water or tapping point, similar to a gas station. The water is paid on advance payment, a sophisticated prepaid system. Each tap is equipped with a contactless card reader. The water consumer can use his cell phone to charge a certain amount to the card through the CWC Administrator. After the charge has been made, the consumer can draw water as long as there is a balance in his water account. A certified security service company guards the facility and the fenced area for 24 hours and seven days. During the daytime during the water discharge times, the facility is also supervised and supervised by trained personnel. Each location is directly connected to the central administration via the GSM network. Production, water charges, disruptions or unforeseen events are transmitted online. In the event of a GSM power failure, the system operates autonomously for a certain time. The respective water charges and other operational data are stored in the local management system. Another advantage of the prepaid card system is that if there is a shortage of water consumers can be reduced in solidarity.
- The local facility operator staff is trained at the ITC Training Center on a regular basis.
- In the first year of operation, the population, together with CWC, will cultivate the agreed forest area of 1'000 m2, and in the future, maintain and maintain it.
