In the face of increasing global challenges, such as water scarcity, population growth, and environmental degradation, sustainable management of water resources and wastewater treatment is a major concern. However, sometimes the potential impact of water system management on the environmental implications contained in the production process of water and waste treatment systems is omitted. This study sought to assess the environmental efficacy of an integrated water supply and wastewater system in the Semarang City. The secondary objectives of the study were to ascertain the extent to which each stage of the system contributed to the impact categories that were analyzed. Life cycle assessment is a method to evaluation of the environmental impacts associated with water resource and wastewater management, using 1 m3 as functional unit. The stages of water use are not examined in this study. Another restriction is the absence of information about the city’s untreated wastewater quantities’ final destination. Water treatment plant include water withdrawal and water distribution are most impacted under the climate change environmental impact category and other impact that assess until 99%. In seven of the eight impact categories examined, power consumption is the most impactful input.

Transitioning to a circular economy as an option of mitigating environmental challenges posed by traditional linear consumption patterns has garnered considerable attention. This study examines innovative approaches to circular economy principles in the context of Salatiga’s domestic waste management. The aim is to conduct a thorough evaluation of various waste management technologies and their potential to contribute to a more sustainable and circular waste management system. The research utilizes a review-based technique, drawing insights from current academic literature, papers, and case studies relevant to circular economy practices and household waste management technologies. To find new methods that have been successfully implemented in a variety of cities, a comprehensive literature search is performed. This research attempts to give a thorough evaluation of these methods relevance to the Salatiga environment by assessing their accomplishments, obstacles, and outcomes. This research showed that several waste management techniques, such as landfilling, incineration, and minimal recycling, are used in Salatiga. The research uncovered a number of novel methods for enacting a circular economy, including community-based recycling programs, waste-to-energy conversion, and expanded producer responsibility efforts. Few people are aware of the issue, there isn’t enough support system in place, and resources are restricted.
