Just imagine building a house without needing to put in sewage pipework . . . The savings are fantastic, not only in the initial build, but therafter in ongoing water costs. If you install a greywater treatment system for the rest of your waste water, you don’t need a mains drainage connection or a septic tank.
With waterless separating toilets, or incinerating toilets this is not only possible, it is simple.
Look at the options:
Separating Compost Toilets:
These toilets use no water, so your water bills are reduced typically by 30-40%. The toilets can be installed almost anywhere within the house as there is no constraint of having to drain to the sewage pipe – this frees the architect or designer to place toilets in the most convenient places, rather than all along one side of the house, which is typical. Depending on the location of the toilet, the urine can either run into a soakaway, or into a sink or shower waste. The toilet vent needs to be connected to an outside wall, but this avoids the need for any other vent. With heat recovery systems, this vent can run into that unit, ensuring that no heat is wasted by the toilet (something which happens every time you flush a WC!)
The only additional work required with a compost toilet is the occasional removal of the solids bin, but since this is capped whilst still in the toilet and emptied in the garden composter with virtually no smell, it is not an arduous task and the benefits far outweigh this additional task.
An additional minor benefit is that there are no unsightly soil stacks running up the building.

These toilets use 230 volt electricity to incinerate all the toilet contents to a small quantity of ash. The toilet just requires a vent to an outside wall (with a raised pipe for ground floor toilets to avoid hot exhaust gases). Again the toilets can be located where they are needed without any concerns for connecting to drainage.
Occasionally the ash would need removing – it can either be put in the refuse, or sprinkled on the garden as sterile fertiliser.

There are many underground greywater treatment systems or, if space allows, a reed-bed can be used adding an attractive garden feature. However, for those who have limited space and don’t want the expense and hassle of burying a treatment plant, then our WHALE system may offer a good alternative. This uses a holding tank to collect the water and then pumps it through a serious of gravel filled troughs planted with small reed-type plants to aerate and clean the water. The output is then stored in a lower tank from which it can either be run off for use in watering the garden or washing the car, or pumped back into the house for re-use in washing machines or other uses where potable water is not required.
