Ecological Waste Water Treatment is an isolated gravel field into which the waste water is piped. In the gravel there are growing the water plants used for cleaning the water. The plants clean water thanks to the aerobes living nearby their roots, which purify waste water up to 95-98%.
The EWWT is an appropriate solution for individuals, communities and businesses. An advantage is that there is no need of electricity and EWWT requires hardly any maintenance, therefore operating expenses are up to 80-90% lower compared to the mech.-biolog. WWT.
