Rainwater harvesting from roof is considered as valuable water resources. Material Flow Analysis (MFA) of water in Mahasarakham University (Khamriang Campus) shows that rainwater harvesting from roof can reduce water supply production by 7% and save more than 200,000 Bt/year for water treatment cost. The sensitivity analysis suggests that by 5% water supply conservation and 20% additional rainwater harvesting, MSU could have enough water resources. The rainwater is suitable to be substituted water for gardening due to the convenience to assemble an above ground storage tank or a pond to store harvested rainwater from roof. The current practice of rainwater is collected and discharged into drainage system and treated in wastewater treatment plant. Utilisation of rainwater harvested could reduce wastewater amount that must be treated by 9%. Rainwater harvesting and reuse should be promoted in campus in order to encourage sustainable living and water conservation policy.

This paper reports results from a survey of households in Poland concerning the use of alternative sources of water. Research showed that respondents were not too inclined to replace water from the water supply with greywater and rainwater. They would be afraid of using both greywater (79%) and rainwater (60%) in their household. The biggest concern was the use of alternative sources of water for doing laundry - more than 50% of respondents identified this issue in both cases. Only 43% of respondents would like to install a greywater recycling system and much more -78% a rainwater harvesting system. For the vast majority of respondents (80%) a subsidy would be an incentive for using these systems in their household.

The current human use of global natural resources exceeds the long-term sustainable capacity of the planet. New and more sustainable ways of building cities and providing urban water services are needed. The Australian city of Sydney is expected to grow by more than 1 million people over the next 30 years. Water use from the Hawkesbury-Nepean River system already exceeds system capacity. Current proposals to allocate a greater proportion of low flows to meet environmental flow needs will limit urban water allocations and require the development of more efficient water and sewerage systems for new and existing urban development. This paper presents a hypothetical case study of how water supply and sewerage services might be provided for an additional 1 million people over a 25-year period. It compares traditional service provision with alternative scenarios incorporating water conservation measures, rainwater harvesting and water reuse. The paper presents both economic and environmental comparisons. The economic comparisons include valuations of environmental externalities in the form of environmental levies. It shows that the extra capital costs of water conservation, alternative water sources and water reuse scenarios are offset by operating savings and environmental benefits. Ecological footprints are reduced because of lower water diversions, discharges, energy use and CO2 emissions. The paper also discusses the implication of alternative infrastructure ownership and water pricing arrangements, and the opportunities to create incentives for additional investment in water conservation and reuse projects.

Water Scarce

Availability as well as access to drinking water is one of the considerable constraints for achieving sustainable goals in many countries while microbial contamination has exacerbated this issue more significantly. The increasing trend of population and industrialization for economic growth has adversely been affecting fresh water resources that eventually leading to scarcity of available drinking water. Hence, controlling water pollution along with focusing on alternative water sources are important for ensuring access to safe drinking water. This study aimed to determine the biological water quality parameters of rainfall water in the water-scarce areas of Bangladesh. About sixty rainwater samples collected from seven different districts were collected for microbial analysis in particular Total Coliform (TC) and Fecal Coliform (FC) by using membrane filtration and direct counting method. The result found that 70 % of samples were free from total coliform, whereas only 5 % samples showed above 100 colonies. On the other hand, 83% samples were free from fecal coliform, whereas only 2% samples were within the range of 11-100 colonies. This study has also revealed that most of the samples collected from Rangamati and Khulna district were free from total coliform and fecal coliform. This study may also encourage people living in these water scarce areas to come forward for rainwater harvesting system as a prospective tool for achieving sustainable goal in drinking sector of Bangladesh.

Alternative Water Sources

Alternative water resources are gaining momentum in Catalonia (north-east Spain) in an effort to promote water conservation and build resilience against drought episodes. Since 2002 more than 50 municipalities (summing up more than 1.3 million people) have approved a water saving ordinance that involves the installation of rainwater harvesting and/or greywater reuse systems in new buildings. These new technologies trigger important transformations in the existing water cycle including institutional and social changes related with water decentralization. Drawing on interviews with local environmental managers and survey data from rainwater harvesters and greywater users, this paper analyses the social and technical learning generated during the implementation of the regulations and the main impediments and barriers that need to be overcome to control health risks and promote social acceptance of these alternative water sources.

Water conservation in buildings includes not only reducing the demand for potable water, but also adopting alternative sources for activities with less noble purposes. Public buildings under the jurisdiction of the Federal, State, and Municipal governments are required to promote actions aimed at the rational use and conservation of water, according to the responsibility established in the Environmental Agenda in Public Administration.In light of the above, this study aims to analyze the potential for reducing drinking water consumption at the headquarters building of the Electoral Regional Court of Pernambuco - TRE/PE through the use of alternative water sources, such as rainwater and condensed water from air conditioners. The methodology began with the characterization of the study site and the consumption of potable water.Subsequently, the technical and economic feasibility of rainwater and condensate water use was investigated, as well as a comparison between the proposed measures. The results obtained indicate that the techniques studied are beneficial, presenting significant potential for reducing the consumption of potable water that would be used for toilet flushing, 63% for rainwater use and 62% for condensate water.In addition, they can also provide annual financial savings of R$8,216.01 and R$8,045.74, respectively. Thus, besides reducing drinking water consumption, the proposed measures also promote the minimization of financial costs, whose capital can be used in the search for continuous improvement of services provided to society.
