Over the last years HELIOZ not only was the master mind behind the development of WADI, we participated in international R&D developments such as the WATERSPOUTT Consortium.
Research & Development
WATERSPOUTT aims to increase the user uptake of SODIS by designing, piloting and bringing to market three novel solar based technologies (Solar rainwater reactors / STU, Solar jerrycans and Solar-ceramic filtration). These technologies will be designed in consultation with end users in Africa and will be piloted in Uganda, South Africa, Ethiopia and Malawi. WATERSPOUTT technologies will have an estimated market of more than 102 million potential end-users in Africa in addition to 50 million elsewhere (Asia, Europe, Latin America). The consortium consists of 15 renowned universities from Africa, Asia and Europe, which contribute their expertise in the fields of micro-biology, material science and social sciences.
HELIOZ is among the founders of the research consortium and contributes its sensor technology and implementation know-how. The goal is to market the developed products, for which HELIOZ will hold exclusive rights. With new R&D projects such as the STU and SDI HELIOZ will be a leading company in the area of water treatment. For this development we seek additional funding and new partners, offering the participation in the overall structure of the HELIOZ Group and joining the existing round of investors.
For further development and preparation for the market entry of our products following the successful development further involvements will be needed. Join HELIOZ R&D as a Lead Investor for the next steps of product developments such as STU and SDI.
Solar Treatment Unit (STU)
The STU is a solar powered technology, providing disinfected drinking water with the SODIS method regularly in a large scale, using WADI as a UV measurement dedicator. There are no additional energy sources needed which makes it to a standalone, environmentally friendly easy to use solution. It’s a long-lasting device with no need for any spare parts and very limited maintenance activities. All the needed maintenance can be done by locals in a quick and easy way. The lifetime of the device exceeds several years, based on a proper and regular maintenance. The STU can be used as a household solution for small environments, but also in a bigger scale for communities like a village, schools, community centres or water ATMs. It’s ideal to treat stored rain water from harvesting tanks, piped water or surface water from near water sources. The STU builds on the SODIS treatment to make sure the provided water is safe to drink; this method is certified by the World Health Organisation (WHO).
With this new product HELIOZ will be entering the market for community-based solutions in water treatment. We will focus on our existing markets in India and Africa together with our partners for implementing this in CSR and B2G projects. Future developments in discussion are including this technology in WASH centres in semi-rural areas in India in projects with the Minister of Water in India.
Solar dose indicator (SDI)
With the SDI we bring Internet-of-things to the target countries and use this digital solution for impact measurement and real-time verification. Furthermore, we can determine the approximate amount of CO2 saved on a daily basis and make it available to our customers. The SDI basically has the same function as the WADI, but with an improved connectivity to a cloud service, so we can track the use of the SDI as well as the incoming UV value at a dedicated place.
With the option to create a network of SDI stations, well dispersed over a region, we can continuously map the incoming UV-radiation providing the service on demand without actually having the device or being at the station. This can help providing the SODIS method to a bigger community more cost efficiently and simultaneously provide on time real data about the use of the method.
We use the information to get live data from a single point to compare and improve project regions, and it helps us to understand the use of the WADI and the SODIS method, when can it be done and how often a day. We also monitor different weather conditions all over the year.
