DEWdrop
DEWdrop Greywater Treatment
Isidima's Decentralised Ecological Wastewater Treatment is now expanding to ecological greywater treatment. Developed under the WADER program, the DEWdrop system treats household greywater to recover 'water from waste'. The recycled water will be suitable for garden watering, micro-irrigation systems, toilet flushing and car washing. Furthermore, while the standard DEWdrop runs on a 230V mains connection, this can be affordably upgraded to run solely on solar power.
What is greywater?
Greywater compatible with the DEWdrop is all water draining from washing machines, baths, showers and bathroom basins.
