Rainwater harvesting systems (RWHSs) have been accepted as a simple and effective approach to ease the worsening of urban water stress. However, in arid and semiarid regions, a comprehensive method for promoting domestic RWHSs in a large-scale water-saving scheme that incorporates water consumption reducing equipment (WCRE) and gray water reuse (GWR), has not been well developed. For this, based on the case study of Guilan Province, Iran, this study addressed the temporal-spatial complex of rainfall and proposed a GIS-simulation-based decision support system (DSS). Herein, two scenarios, i.e., the typical RWHS and the modified RWHS for arid areas, were tested; and the associated economic analysis was performed and compared with WCRE and GWR. Moreover, for larger-scale implementation, the multiple criteria decision making (MCDM) technique was further applied to address the social-environmental complexity of these water-saving methods. Guilan Province has thereby been classified into three priority levels, providing a straightforward understanding of how to promote the large-scale water-saving scheme. Compared with the traditional generalized method, sensitivity analysis verified that this DSS enhanced the information value. Hence, the DSS that provides more holistic and comprehensive support has been identified as a useful tool to ease the threat of urban water stress.

Abstract New industrial and urban developments in water-scarce regions are often inhibited by their high demand for water from natural resources. In addition, there often is a lack of water for purposes that contribute to an improved quality of life, such as urban green spaces. Therefore, the integrated industrial-urban water-reuse concept presents a strategy by linking and reusing treated industrial and municipal wastewater flows to increase urban water-reuse potentials. The concept of combining different reuse water flows, from wastewater treatment plants from industrial parks, aims at significantly increasing the water-saving potentials compared to a separate consideration of the industrial wastewater flows.

Community engagement and involvement is vital for the success of urban water management. However, poor public engagement, cheap water tariffs, apathetic attitude and lack of public interest are identified as the main reasons for high water wastage in Penang State, Malaysia. The N Park Resort Condominium rainfall harvesting and water saving project in Penang, Malaysia is a prime example of successful urban water management involving government, private sector, non-governmental organisations (NGOs) and local communities. The N-Park condominium consisting of 965 units is the first condominium in the country to initiate a community water- saving project. Started in August 2009 and completed in December 2010, the project is jointly implemented by the Drainage and Irrigation Department (DID) Malaysia (Government), Water Watch Penang (WWP) (NGO), N-Park Management Corporation (NPMC)(Community) and the Penang Water Supply Corporation (PWSC). The methodology involved installation of a rainwater harvesting system, installation of water-saving devices and a water-saving campaign. Results of the project showed that the rainwater harvesting system was most successful as the rainwater harvested was used for gardening, washing common areas and toilets, flushing toilets, and washing vehicles. The installation of water-saving devices was also successful as it resulted in substantial water savings. Results showed reduced total water usage from 8 to 25 % between September 2009 to March 2010. The greatest reduction by 50 % was between May and July 2011, followed by 47.5 % in January 2011. During the time of the project, the amount of water saved was equivalent to RM1,3971 in monetary savings per month. Over a year, this is translated to a savings of 16,818 m3 of water or the equivalent of RM 16,782. More recently, between February 2020 and April 2021, the average water saved was 5852 m3 per month or averaging 48.77 % per month, equivalent to about RM34,255. Results also showed enhanced water awareness and better relationships between neighbours. Overall, this project proved that collaboration between government-private sector-NGOs is workable, and the project can be replicated nation-wide in apartments, hotels, factories, universities, and schools.
