Composting Toilets | Nature Loo | Rota Loo | Clivus Multrum | Grey Water Treatment Australian families flush 78 billion litres of water every year, and in 11 years from 1980, local and state governments had spent $10.6 billion on sewerage systems and treatment. This accounted for 11.6% of total government expenditure. Concentrations in the effluent from a septic tank are in the order of one million times the concentration of what comes out of a composting toilet, and roughly 50% of septic systems do not work properly. One person using a flush toilet will produce eight tonnes of waste water in a year. In the same period a Rota-Loo composting toilet produces about 20kg of disease free compost which can be uesd as organic fertiliser. Some composting toilets are cheaper than the Rota-Loo because they are simpler to construct. Rota-Loo has a minimum of six separate compost bins contained on a turntable, inside a holding tank.The bins remain inside the tank, safely shut off out of harm's way. There is no need to remove any container holding fresh waste for storage elsewhere. Rota-Loo is designed as a composting system without the requirement of earthworms, cardboard or organic matter to make it function. However, if a user wishes to add earthworms to the composting process, this can be done. Rota-Loo is factory assembled and is easily installed by a handy person.
