Solar Driven Drinking Water Treatment for Remote Regions

 Solar Driven Drinking Water Treatment for Remote Regions


The SuMeWa|SYSTEM removes impurities from water to provide safe drinking water supply in rural locations.


Key Features

SuMeWa|SYSTEM treatment technology is designed to ensure safe drinking water supply even in the most remote regions. 

Through the use of adequate treatment steps, our stations are capable of removing impurities such as iron, arsenic, manganese, turbidity, organics and, most importantly, bacteria and virus without the need for membranes. 

Long-term disinfection of the water is ensured through electrolytic chlorine production, either from the natural chloride content of the water itself or the use of table salt (NaCl). This way the station can operate independently from any external chemical and electricity supply and at the same time meets the strictest water quality requirements. Currently our biggest stations can supply up to 200 m³ of safely disinfected water per day. The stations are usually powered 100% with solar energy. 

Drinking water is dispensed via water ATMs at very marginal costs. The generated income hereby allows long term operation and maintenance of the water supply infrastructures. Usually any surplus generated is reinvested into the extension of a treatment supply network

Social Impact

Technical solutions to treat drinking water have always been available and, in the past years, even more solutions have entered the market. For disinfection purposes, membrane filtration and UV systems have become popular. Despite those solutions being capable of removing bacteria and to some remove viruses from the water, they do not prevent recontamination during transport and storage. Recontamination is very common in membrane and UV systems and the addition of chlorine is urgently necessary – and required by the guidelines. Simple chlorination to assure residual disinfection, however, has failed in rural developing regions, due to the lack of continuous supply of chemicals and knowledge on correct dosing. Due to the fact that chlorination is commonly neglected, that could have deadly consequences for the consumers. 

Our solution is the only one that is able to meet the disinfection requirements and residual chlorine supply. With our technology, diluted chlorine solution is produced onsite, either from the natural chloride content of the water itself or NaCl. 

Water provided by us is and stays free of pathogens and that helps to improve health conditions of consumers – even in the remotest regions.

Currently more than 50,000 people worldwide are supplied with safe and healthy drinking water through our solution. 

With each station, between 3 and 4 people are employed long term. 

Future Plans

AUTARCON strives to increase sales and now offers business models which allow investors to finance water supply projects. By that water can be offered at very marginal costs to the communities most in need. A constant flow of income hereby guarantees the long term operation and maintenance of each station and reimburses the investment costs. 

Main Target Group

Currently we are selling to NGOs, private project developers, and research facilities, which are in need of comprehensive water treatment and supply solutions.

Main User

Water supply agencies, remote villages, private entities, hotels, research stations.

Price (in USD)

The costs of the stations currently range from USD $15,000 to $300,000 depending on size and water treatment requirements.

"To me, there’s nothing more special than providing food for other families, and that’s what we do out here."                                                   - Wanda Patsche   Agriculture   is the art and science of cultivating the soil, growing crops, and raising livestock.  Agriculture  provides most of the world’s food and fabrics. Cotton, wool, and leather are all agricultural products.  Agriculture  also provides wood for construction and paper products. Where it begins, Over centuries, the growth of  agriculture  contributed to the rise of civilizations.  Before  agriculture  became widespread, people spent most of their lives searching for food—hunting wild animals and gathering wild plants. About 11,500 years ago, people gradually learned how to grow cereal and root crops, and settled down to a life based on farming. By 2,000 years ago, much of the Earth’s population had become dependent on  agriculture . Scholars are not sure why this shift to farming took place, b

PAVEGEN-TILES MAKING ELECTRICAL POWER

  PAVEGEN-TILES MAKING ELECTRICAL POWER Introduction: With the increasing demand for sustainable energy solutions, many innovative technologies have been developed to harness renewable sources of energy. One such technology is the Pavegen system, which uses the kinetic energy generated by footsteps to generate electricity. Pavegen is a revolutionary energy harvesting system that can be used to power street lights, buildings, and other public infrastructure. What is Pavegen? Pavegen is a technology that converts the kinetic energy generated by footsteps into electrical energy. The system consists of a series of floor tiles, which are embedded with piezoelectric crystals. When someone steps on the tiles, the crystals compress and generate a small electric current. This current is then stored in a battery or fed directly into the power grid. The Pavegen system has been used in a variety of settings, from sporting events to retail stores. It has even been installed in public spaces such as
