Line 77:
At more realistic levels, developing countries can strive to achieve primary wastewater treatment or secure [[septic system]]s, and carefully analyse wastewater outfall design to miminise impacts to drinking water and to ecosystems. Developed countries can not only share technology better, including cost-effective wastewater and water treatment systems but also in [[hydrological transport model]]ing. At the individual level, people in developed countries can look inward and reduce overconsumption, which further strains worldwide water consumption. Both developed and developing countries can increase protection of ecosytems, especially wetlands and riparian zones. These measures will not only conserve [[biota]], but also render more effective the natural [[water cycle]] flushing and transport that make water systems more healthy for humans.
There are also a range of local, low tech solutions that are currently being pursued by the likes of Sodesa, Aqua-Aero WaterSystems, and AquaDania, which are centred around the use of solar power to distill water at just under boiling temperature. The idea is that any water source can be purified, and that local business models can be built around these new technologies, thus helping to accelerate uptake.<ref>[http://www.cnbceb.com/ViewArticle.aspx?PageID=1248 Tapping A Market] CNBC European Business, October 2008</ref>
