Permaculture Sewage Treatment – First Aid and Future Proofing for our Rivers and Seas

If we want to create sustainable, healthy systems to support us, we cannot rely on such a fickle friend as fossil energy for electricity generation to keep our sewage treatment systems running smoothly. Quite apart from the increasing potential for power cuts in a changing world, when conventional sewage infrastructure “runs smoothly” it is still heavily reliant on the constant use of electricity to convert biomass and nutrients into somewhat less polluting effluent before disposing to our rivers and coastal waters. Clearly in a world desperately in need of solutions that work, this needs to change.
