The Hatachi group has gained extensive knowledge using technology such as pumps for water purification, rain water and sewage water conveyance and utilize their expertise as they participate proactively. Hitachi objective is to ensure everyone has access to safe and clean drinking water. It provides ozone microbubble technology for reusing sewage as water resources are limited. They are also active in the "Water Plaza" project to create advanced water circulation systems.

Nasa is using technology developed for their space stations. Engineers developed cutting edge water purification systems that recycles air and water aboard their station. They have adapted that system to an Earth-based water treatment system. Joint collaborations between aid organizations and Nasa technology shows how effective space research can adapt to solve global needs.

The Swiss clean water group patented a water treatment technology with six steps ; pressure pumps, crystal quartz canister, oxygen production, filters, mechanical fine mesh filter and UV light and it's able to transform polluted water into high quality drinking water. The awesome thing about the Swiss clean water group technology does not use chemicals, does not use waste input water, and only uses the equivalent of two 75W lightbulbs to function, leaving a lower amount of carbon emissions compared to other technologies.

Technology has helped, and still is currently helping, people have access to clean drinking water. Without the technology to clean the water and find filtration's and methods to cleanse it the water would remain dirty and/or contaminated and it would remain undrinkable. These groups, along with their resources, technology and dedication have delivered clean drinking water to those in need.
