Greywater Reuse

Domestic wastewater reuse is currently not permitted anywhere in Australia but is widely supported by the community, promoted by researchers, and improvised by up to 20% of householders. Its widespread implementation will make an enormous contribution to the sustainability of water resources. Integrated with other strategies in the outdoor living environment of settlements in arid lands, great benefit will be derived. This paper describes six options for wastewater reuse under research by the Remote Area Developments Group (RADG) at Murdoch University and case studies are given where productive use is being made for revegetation and food production strategies at household and community scales. Pollution control techniques, public health precautions and maintenance requirements are described. The special case of remote Aboriginal communities is explained where prototype systems have been installed by RADG to generate windbreaks and orchards. New Australian design standards and draft guidelines for domestic greywater reuse produced by the Western Australian State government agencies for mainstream communities are evaluated. It is recommended that dry composting toilets be coupled with domestic greywater reuse and the various types available in Australia are described. For situations where only the flushing toilet will suffice the unique “wet composting” system can be used and this also is described. A vision for household and community-scale on-site application is presented.

In the past sewage ponding in indigenous settlements was commonplace as a result of overcrowding combined with inappropriate septic tank and leach drain design, installation and operation. The response over the past 10 years has been to develop reticulated sewerage systems to lagoons when the funds become available. These are often successful in terms of operation, improved public health and low maintenance but are expensive and wasteful of limited water supplies. Evapotranspiration (ET) is an effective method for on-site domestic effluent disposal in areas of Western Australia with soils of low permeability. Evapotranspiration systems have been established in a number of communities both for research/demonstration and as specified by architects. The systems usually follow two septic tanks for the disposal of all domestic effluent. A case study will be presented for a remote indigenous community where the ET systems installed for greywater only have been monitored over the last two years since installation. The use of evapotranspiration has enabled reuse of effluent for successful examples of revegetation and food production and points to the need for a holistic approach to design and service delivery in these communities that includes a total environmental management plan.

The increasing variety of industrial activities in Indonesia resulted in ground water reserves in some areas experiencing drought. Exploitation of ground water by industry and the community in some big cities like Jakarta, resulting in the decrease of ground water and ground water quality reduced caused sea water instrusion. While the potential of wastewater produced by industrial and household waste high today. Based on the matters mentioned above and see the use of ground water that will be even greater in the future, then one of alternative that a lot of attention in many countries around the world are using wastewater reuse, particularly urban domestic wastewater (municipal wastewater) as a source of raw water for water supply. BPPT as a government office has made use of wastewater reuse technology, however, when the performance of the appliance is not working properly for it is necessary for re-evaluation and selection of wastewater reuse technology for better and sustainable. Keywords : Wastewater Reuse Technology, Domestic Wastewater, Water Consumption Survey

The first subsurface flow wetland (SSFW) system for about 1,000 PE, was constructed in Nicaragua in 1996 to apply this technology in the form of an integral project, combining the treatment of domestic wastewater with its reuse for crop production in small and medium size communities. The SSFW-effluent meets all standards established in the national regulations for wastewater reuse in agriculture, except for faecal coliforms, existent at an average concentration of 7 × 104 MPN/100 ml. A conventional surface irrigation method was used to irrigate different crop species selected to establish their risk of contamination. To judge the potential health risk for consumers and farmers, samples of vegetables and fruits harvested in the dry seasons of the years 1997 to 2002, were analyzed for the presence of pathogenic microorganisms like faecal coliforms, salmonella and shigella. In addition, a yield comparison between crops irrigated with well water using chemical fertilizers, and crops irrigated with the effluent of the SSFW-system was made, to analyze the economical benefits of the wastewater reuse.

A type of wastewater reuse system for domesticity with remote-control is presented in this paper. For domestic water-saving, the wastewater reuse system is designed via hydromechanics, and its remote-control system is discussed. The system consists of wastewater storage tank, electromagnetic valve, electronic remote-control device, and pipelines. The principle of its water-saving is also analyzed in three control models. The results indicate that the wastewater reuse system can make the best of reusing domestic bathing and washing wastewater to wash down toilet bowl in order to save water supply. Electromagnetic valve is convenient to control and has good seal performance for avoid wastewater leak. Two enactment time control models and a manual control model can effectively satisfy with user, farther to save wastewater

A model of land suitability analysis for irrigation with treated domestic wastewater is presented. The model integrates tools of Multi-Criteria Evaluation with Geographical Information Systems. Several criteria were selected to adapt the model to the conditions and characteristics of the case study. The adaptation process included field visits, a bibliographical review, and personal interviews with local actors and experts. Six constraints and 10 factors were selected and 3158 hectares suitable for the activity were identified. The areas were classified into three categories of aptitude, representing high fitness sites close to the current wastewater treatment plant. The developed tool allowed us to integrate different criteria to assess site suitability for wastewater reuse, with the advantage that the tool can be adapted to other regions and/or objectives.

The Impact

The paper aims to evaluate factors according to the planned behavioral theory of the community’s intentional attitude towards wastewater reuse. A huge amount of domestic wastewater will deplete water resources if not treated and reused. The survey results from more than 1000 households in the three major cities of Vietnam (Hanoi, Ho Chi Minh, and Da Nang) show that the community’s intention is good and all have a positive impact on the people’s satisfaction and water cycle management performance. All five factors: emotion, fairness, health risk, subjective norm, trust, have a positive impact on intention to use reused wastewater. Different from other studies, this research assesses the impact of intention to reuse wastewater on community satisfaction. Previous research showed that health risk negatively influenced intention; this study showed that health risk positively influenced intention and community satisfaction.

Southern Portugal

Treated effluent from an aerated lagoon and facultative pond system in southern Portugal, was used to irrigate fields planted to maize (Zea mays L.). The effluent was characterised with respect to its nitrogen and phosphorus content and applied by drip irrigation in response to crop evapotranspiration requirements. Nitrification of ammonia in the effluent by soil microorganisms caused a reduced soil pH early in the growing season, but this was reversed as the season continued. For most of the growth season plant nitrogen demand ensured a low soil nitrogen concentration, but towards the end of plant growth the continuous nitrogen supplied in the effluent exceeded crop requirements with a result that nitrate accumulated in the soil. The applied effluent also had a high phosphorus concentration but there was only a slight accumulation of this in the soil. The fertiliser value of the treated effluent was demonstrated by increased yields at physiological maturity and the N yield was within the range of expected values for this crop. The main removal mechanism for N during irrigation was crop uptake whereas P was removed primarily by soil processes. The advantages of wastewater reuse together with the importance of appropriate management practices for re-use are discussed.
