The standard requirements for waterless residential composting toilets are covered by AS/NZS 1546.2:2008 On-site domestic wastewater treatment plants – Waterless composting toilets. It specifies confidentiality requirements and the number and location of sanitary facilities. Release to a plumbing and drainage system is required under section G13 Waste Water for Water-Based Disposal and into a safe and healthy disposal system when non-water-based disposal is used. If a composting toilet is not properly maintained and monitored, the final product cannot be composted properly, which means: helping designers and building owners plan toilet layouts for commercial buildings (including privacy and accessibility). There are also specific legal requirements regarding ventilation of wet rooms, etc., which only apply to rental apartments. You can read more about this in the Healthy Home Standards here. The acceptable solution E3/AS1 provides a means of meeting the requirements of clause E3 for internal moisture.
Composting toilets must contain pathogens and act on them. You must: Any glazing located within 2 m of the ground in bathrooms and spa rooms must be made of safety glass according to NZS 4223.3:2016 Glazing in buildings Part 3: Safety requirements for human influence. This clause confirms that personal hygiene facilities are provided to protect against diseases caused by infection or contamination. Its requirements protect against loss of amenities and allow people with disabilities to engage in normal activities. Waterless composting toilets constructed separately from the house fall under the description of a building under the Building Act, 2004. For composting to take place, the moisture content in a composting toilet must be minimal. This usually requires the separation of urine by evaporation or a separate collection system. A composting toilet cannot be used in urban areas where there is a sewage system.
According to the building code, washrooms must be connected if a sewer connection is available, unless the building permit authority waives it. This provision takes into account compliance with the regulations of large toilet paper distributors installed in prefabricated public toilets – the position of the dispensers is different from that indicated in the corresponding acceptable solution. Prefabricated toilets are built on the basis of a permit issued at the place of manufacture and are installed throughout the country with a separate building permit for on-site installation. Flushing toilets accounts for about 20% of domestic water consumption. Composting (or waterless) toilets eliminate the need to flush the toilet. Use this calculator to find out how many toilet tubs, sinks and urinals are needed in a building. A composting toilet breaks down human waste and other organic matter added through an aerobic process in the same way as garden compost. The final product should be odourless, earth-like humus that can be buried on site. More than 120 building standards used to comply with building codes are now available for free download. For the proposed disposal method, municipal council approval must be obtained. These documents are provided as assistance. They are not intended to determine compliance with the Building Act or the Building Code, and they do not have the same status accorded to acceptable solutions and verification methods under the Act.
Acceptable verification solutions and methods (SA and VM) have been referred to as compliance documents. Some still have the title «Compliance Document,» but the ASs or virtual machines they contain are valid and are not affected by the name change. Other building code clauses that may apply to wetlands are summarized in the following table (see www.building.govt.nz/building-code-compliance/). The objectives of section E3 are: water use, sustainability and efficiency through the selection of quality systems and materials and the provision of environmentally friendly solutions. This provision shall take into account the conformity of a floor attachment space which does not contain a palm. The provision addresses the term «immediately adjacent» and whether the floor securing space without sinks complies with section G1 of the Building Code Personal Hygiene by Acceptable Solution G1/AS1 and, if not, whether the room fits section G1 as an alternative. All standards, including those funded, are available on the Standards New Zealand website. All products, systems, and designs that have achieved CodeMark status are listed here with their most recent certificate. AS/NZS 4858:2004 Wet Membranes is another key document.
The Building Performance team has begun digitizing building codes as demands from construction professionals who need critical information in a portable, dynamic, feature-rich and digital format increase. We delivered the first of our Building Code PDF documents (B1, C/AS2, D1 and E2) to our digital reader. The design and installation of wetlands must comply with clause E3 of the NZBC Internal Humidity. Decisions are made by MBIE in case of doubt or disputes related to the construction work. Judgments are legally binding in all cases. The circumstances may differ from others in one case. MBIE has historical versions of code clause documents, which can be found under Previous Versions and Version History. Alternatively, if you can`t find the document you`re looking for, you can send an email with the year and code clause you`re looking for for info@building.govt.nz. Standards are often mentioned in acceptable solutions and verification methods. They provide practical information and guidelines for creating solutions. RO 3740-2010 Domestic wetland waterproofing is a reference standard for wetland sealing, although it is not referenced in building code compliance documents.
However, E3/AS1 currently contains relatively little information, so compliance with clause E3 will often be ensured through the use of alternative solutions. They require a commitment to monitor and maintain the system, which includes: Poor design or installation in wetlands can compromise the safety, comfort and convenience of building occupants and cause significant structural damage.
