During theprevious 8 years, since development plumbing product manufacturers have embraced sustainability and made significant improvements in the flushing performance of water closet suites. These developments have rightfully raised the debate of drainline carry efficacy. Many plumbing experts have questioned whether these reduced flush volumesâ€¨are approaching a tipping point where some sanitary waste systems would be unable to function properly. Of particular concern are installations with long horizontal runs to the sewer. Furthermore some drainline transport problems in Europe and Australia have been reported, further raising concerns. The effect and consequences of a reduction in water flows in small diameter drains, commonly known as dry-drains, has been widely studied.

The National Plumbing Regulators Forum (NPRF) for Australia and New Zealand formed the Australasian Scientific Review of Reduction of Flows on Plumbing and Drainage Systems (ASFlow) to study the issue of dry drains.

In ***9, a Dry Drains Forum was convened as part of the ISH trade show in Frankfurt, Germany. At this forum, several prominent researchers and other industry experts provided further information on the causes and effects of starving drainlines of liquid flows. Similarly at the ***9 CIB- W**2 conference convened in Dsseldorf, Germany the issue was again highlighted. The presenters were unanimous in identifying the causes and effect of dry-drains. Similarly they agreed upon the fact that with innovative systems and design the objectives of reduced flush toilets and water efficiency drives could be met without compromising the functionality of the drainage system.

In ***8 the Institute for Sustainable Futures (University of Technology Sydney) in a report prepared for The Australian Government Department of the Environment, Water, Heritage and the Arts titled Analysis Of Australian Opportunities for More Water-Efficient Toilets explored whether there are opportunities for even more water-efficient flush toilets than the current Water Efficiency Labelling and Standards (WELS) four star rated toilet models sold in Australia. It specifically examined what would be required to introduce WELS five and six star rated toilet models. The study addressed flush toilets only. Issues relevant to this submission highlighted in the report included;

Water efficient toilets have to include the ability to clear the bowl;
The interaction of the toilet and the drain;
The impact the lower flows will have on the sewer system; and
Regulatory and standards issues.

The report concluded;

that reduced flush volumes do have a negative impact on drainline performance; and
there is indeed a high level of demand for more water efficient toilets.

Internationally numerous authorities and individuals have conducted research into the issue of dry-drains. We reference the following reports together with their key findings/ conclusions;

Wrc (UK) in their October ***9 report for the British Plastics Federation, DEFRA, NHBC Foundation and Severn Trent Water titled Pull the Chain, Fill the Drain studied the effect of reduced water usage on sewer solid movement in small pipes. The study included WC flush volumes of 2.0, 3.0, 4.5 and 6.0 litres.

Principal findings of the study included:

2 litre and 3 litre flush volumes are insufficient to carry the solid at least *0 metres, i.e. nominally to beyond the next connection incorporating a WC.
The addition of paper with the solid increases the effect of the WC flush wave. However, this is a temporary benefit, due to the rapid disintegration of the paper in the drain.
The so called flushable products do not present a risk of blockage when the pipe walls are smooth. However, the presence of small defects significantly increases the risk of snagging and therefore blockages.
Proprietary low flush WC design focuses on WC bowl clearance. It does not give improved flow patterns in the downstream drain and as such does not enable sewer solids to travel further.
The investigations have shown that the concerns regarding reduced WC flush volume and sewer solid movement were justified. A significant reduction in WC flush volumes, for example to a *1⁄2 and 3 litre dual flush combination, is likely to be unacceptable if no other measures are taken to counter the effect of the reduced flush.

The American Plumbing Efficiency Research Coalition (PERC) in November ***2 published a study report titled The Drainline Transport of Solid Waste in Buildings. The study investigated drainline transport performance for 3.0, 4.8 and 6.0 litre flush volumes. The study also investigated the effect of a higher volume clear water clearing flush introduced into the drains after each **0 flush test cycle. The clearing flush would be set and evaluated at *1 L (3.0 gallons) and *9 L (5.0 gallons).

Principal findings of the study included:

Observations of waste movement with in the test apparatus for 3.0 L flush volumes clearly demonstrated a significant difference in performance when compared to other higher flush volumes. At 3.0 L flushes test media compressed together to large plugs, which resulted in full-pipe, or near full-pipe conditions. These plugs eventually cleared themselves prior to water overflows, the PERC TC still found that 3.0 L flush volumes created unacceptable chaotic conditions in the pipes.
The *9 L clearing flush failed to clear the drainline on 7 of the *9 test runs and as a result this potential solution proved to be unreliable and cannot be suggested as a building drain clearing solution.
PERC, like the Wrc, concluded that dry-drains is a real issue for 3.0 L and lower flush toilets.

Based on the above mentioned studies and proponents own research it is reasonable to conclude that with the development and introduction of 3/2 litre and lower flush volumes the problem of dry-drain will only become more prevalent if no alternative measures are included. WMTS***4:***3 acknowledges the issue of dry-drains and utilizing an innovative systems approach to toilets and drains resolves and eliminates the risks associated with dry-drains.

The drivers for maintaining updated and relevant plumbing standards that align with the communities expectations included:

The Green Building/sustainability sector in Australia and worldwide is growing rapidly;
The communitys expectation of regulators providing worlds best solutions;
Increased awareness of water scarcity and the need for increased water conservation efforts;
An increase in the number of enquiries and requests for clarification on the use of WMTS***4 compliant products and their relation to, and impact on, AS***0.2 demonstrate that there is a need for revision to improve clarity and avoid the chance of misinterpretation; and
Misinterpretation of the standard may lead to non-compliant installations.

The Australian Governments Department of Environment through their Water Efficient Opportunities Program continues to promote the use and development of water efficient plumbing. This program
.... seeks to support and encourage water efficiency within Australias commercial and industrial sectors. The commercial and industrial sectors currently consume *5 *0 percent of urban water in Australia and have an important role to play in securing water supplies. Greater water efficiency and use of alternative water supplies by these sectors could take pressure off fresh water supplies in urban areas; resulting in productivity gains, net economic benefits, as well as environmental benefits.

Similarly the Australian property and building industry, through the Green Building Council of Australia (GBCA), is committed to developing a sustainable property industry for by encouraging the adoption of green building practices through market-based solutions. The GBCA aims to achieve its objective by promoting green building programs, technologies, design practices and operations as well as the integration of green building initiatives into mainstream design, construction and operation of buildings.
As part of their promotions program GBCA developed a rating tool to measure and promote sustainability know as Green Star rating. Both industry and government uniquely support the GBCA across the country.

Water savings that can be achieved by utilising ultra low flush toilets positively contribute to the star rating of the building. The increased awareness, acceptance and use of the rating tools such as Green Star add to the necessity for regularly reviewing, updating and maintaining relevant standards.

Public Health and Safety

The safe installation of SDUs within the drainage system has the following health benefits.
Specifically these include:

Safe installation of SDU so that it does not adversely affect the structural integrity of the building
Safe installation of the SDU so that it operates correctly within the drainage system and avoids blocked drains and associated septicity and sewage spills.

The installation of a SDU in itself is a tool in preventing blocked drains and associated septicity and sewage spills and their inherent health dangers. The amendments to AS ***0.2 facilitate the safe and proper installation of SDUs.

Social and Community Impact

Increasing human demand for water coupled with the effects of climate change mean that the future of our water supply is not secure. The Second UN World Water Development Report indicates that if present levels of consumption continue, two-thirds of the global population will live in areas of water stress by ***5. Ensuring our nations long-term water supply requires the use of both supply-sided approaches such as water augmentation through water recycling, and demand-sided approaches such as water conservation.

By incorporating the installation of SDUs and ultra low flush toilets, the proposed amendment to AS ***0.2 positively impacts water efficiency.

Environmental Impact

Water efficiency is reducing water wastage and differs from water conservation in that it focuses on reducing waste, not restricting usage, and the resulting benefits to consumers will be dependent upon educating and awareness building, influencing behavioural changes so that they may acquire water efficient products that reduce water wastage. Most countries have recognized growing water scarcity as a national problem. Water efficiency, while not as yet a major priority in the agendas of governments, has been a growing concern. The World Water Council, the International Water Management Institute and UNESCO have been promoting water efficiency alongside water conservation. Australia strategically leads science, innovation and technology within Asia Pacific and has a strategic intent and interest in promoting environmental friendly green sustainable solutions. These amendments to AS ***0.2 facilitates Australias lead role within the Asian Century.

Economic Impact

Water is vital for all aspects of life and is a crucial resource underpinning Australias economy, society and environment. Water security in Australia is influenced by population growth, environmental degradation, climate change and variability, rainfall, land use, pollution, institutional arrangements and demand for Australias exports, notably of natural resources and food.

The concept of green growth is a core strategy for sustainable development. Green growth, growing productivity, prosperity and living standards while improving environmental and social outcomes, and providing a framework for sustainable economic development that balances environmental, social and technological aspects, is based within the core principle that improvements in economic productivity should not come at the cost of natural resources, the environment or social wellbeing. The proposed amendment to AS ***0.2 adheres to and embraces these core principles.
