What is a waterless toilet?
A waterless toilet is an alternative to a septic tank or a conventional toilet, if you are not connected to a mains sewer.
Waterless toilets can be used as an alternative or addition to other on-site sewage systems. They can be used on sites where mains sewage connection is not an option, and other on-site systems such as septic tanks, aren’t practical (for example, because there’s no room for a soakage area).
A well-designed, well-maintained waterless toilet can be used to turn your toilet waste into compost ready for eventual use in your garden.
A waterless toilet will also save significant amounts of water, which will reduce your costs if you are on metered or limited water supply.
Types of Waterless Toilet
The most common type of waterless toilet is referred to as a ‘composting toilet’. This should be changed to say that “Composting toilets work by separating liquid and solid waste either at the source with urine diversion or in the compost chamber with a false floor.
Bokashi NZ Ltd has been selected as the official supplier of the Australian Ecoflo Wastewater Management Split-system and Self-contained toilet systems which are recognised as world leaders in composting toilet systems.
If you’re planning to install a waterless toilet to deal with all of your toilet waste, you’ll still need another on-site system to safely deal with wastewater from the kitchen, laundry, bath, shower and basin.
Blackwater is wastewater from toilets. Water from other sources such as dishwashing machines, sinks and showers is considered as greywater unless it comes in contact with backwater.
Greywater is waste from baths, showers and hand basins. Wastewater from clothes washing machines may be considered in either category. [/tab]
Under the Building Code, if your property is connected to a mains sewer you must use it. If you are installing a waterless toilet, check with your local or regional council first. You’ll need a building consent for the toilet structure, and you’ll need to check that the toilet you’re considering has approval in your area. Council attitudes and regulations vary. You’ll also need to show that you have installed an appropriate system that can be maintained to an acceptable standard.
