The Gold Coast Water Pimpama Coomera dual reticulation schemes' recycled water supply will be online in late 2009. In an attempt to achieve better estimates on both potable and likely recycled water end uses within this region, this paper presents a predictive model that utilises a range of input parameters, including: current use in the Gold Coast and the Pimpama Coomera regions at both a bulk billing and end use level; recycled water use at other dual reticulated schemes; and questionnaire survey of residents water source preferences for outdoor uses. Prior to the commissioning of recycled water, potable water is supplied through the recycled water pipelines. Water end use consumption analysis from the recycled water smart meter indicates that this supply source currently provides 20% of total household use with the majority of use being for toilet flushing. However, a range of factors have attributed to this low baseline level with evidence collected in this study indicating that higher recycled water consumption rates will occur once this supply line has been commissioned; largely due to the lower cost and fewer restrictions placed on this water source for discretionary outdoor purposes. The weighted amalgamation of a range of baseline adjustment factors assisted in the prediction of post-commissioning end uses for the Pimpama Coomera dual reticulated region. The predictive model indicated that recycled water end uses would account for 53 litres per person per day or 30.6% of total household consumption. The paper concludes with a brief overview of Phase 2 of the study which aims to compare actual post-commission end uses with the baseline situation and prediction, as well as the development of a robust end use model for dual reticulated regions.

A universalização do abastecimento de água no Brasil ainda é um desafio que se busca suplantar, sobretudo em relação ao atendimento a populações rurais difusas, onde os sistemas convencionais não respondem às demandas das famílias de agricultores dispersas. Nesse contexto, as nascentes de água podem contribuir como solução alternativa para o abastecimento doméstico, por se encontrarem próximas ao consumo e sob o controle do usuário Isto é evidenciado no estudo das nascentes situadas no Assentamento Serra Grande, no município de Vitória de Santo Antão, Zona da Mata de Pernambuco. Foram identificadas, cadastradas e selecionadas nascentes perenes, para caracterização da qualidade e vazão das águas, objetivando avaliá-las para usos múltiplos, com prioridade ao abastecimento doméstico. Evidenciou-se que a vazão, mesmo em períodos de estiagem, possui potencial de atender às necessidades básicas dos agricultores, para beber, preparo de alimentos, banho, lavagem de utensílios e roupas e descarga em sanitários. Quanto à qualidade para uso doméstico, em geral a água atende aos limites sanitários, embora em alguns casos a presença de Escherichia coli exija recuperação da nascente e cloração cuidadosa da água. Pelos resultados, a produção de água em nascentes situadas em solos e clima predominantes na Zona da Mata do Nordeste brasileiro, permite atender às necessidades básicas de abastecimento doméstico de agricultores familiares isolados ou em pequenas vilas rurais, sendo uma alternativa aos sistemas convencionais de abastecimento, já identificada pelo governo federal em seus recentes planos de abastecimento de populações rurais difusas. Palavras-chave: recursos hídricos; gestão ambiental; desenvolvimento rural  The Springs as Supply Source of Rural Diffuse Population  ABSTRACTThe universalization of the water supply in Brazil is still a challenge that it seeks to be supplant, especially in relation to the service to rural diffuse population, where conventional systems do not respond to the demands of farming families dispersed. In this context, the water springs may contribute as a workaround for domestic supply, because they are close to consumption and under user control. This is evidenced in the study of springs located at Settlement Serra Grande, located in the city of Vitória de Santo Antão, Zona da Mata de Pernambuco. It has been identified, registered and selected perennial springs, to characterize the quality and water flow, aiming to evaluate them for multiple uses with priority to domestic supply. It was evident that the flow even during drought periods, has potential to meet the basic needs of farmers, for drinking, preparing meals, baths, wash utensils and clothes and flushing toilets. As for the quality for home use, generally water meets health limits although in some cases the presence of Escherichia coli, requires careful recovery of the source and chlorination of water. According to the results, the production of water in springs located in soils and climate prevailing in Zona da Mata of Brazilian northeastern, it allows to meet basic needs for domestic supply from family farmers in small villages or isolated rural villages, being an alternative to conventional supply, already identified by the federal government in their recent plans for the supply of rural diffuse population.  Keywords: water resources; environmental management; rural development

This paper reports results from a study comparing perceived risk associated with various recycled water uses in two Australian locations, both in the state of Victoria: the capital city Melbourne, and Bendigo a regional urban centre. Both locations are experiencing ‘drought’, but Bendigo is experiencing this in a more acute manner. A case study is used in each location. Both case studies involve future use of recycled water in new commercial buildings. An on-line survey was used to measure attitudes to recycled water of the future occupants of both buildings. The study found perceived risk associated with 11 uses of recycled water increased as the use became increasingly personal. Interestingly, no difference in perceived risk associated with 11 uses of recycled water was found between locations. Prior experience (use) of recycled water was found to be a significant and positive factor in reducing risk perception. Various attitudinal variables were found to be significant influences on perceived risk. Results indicate that reducing perceived risk of recycled water use may increase satisfaction with its use.
