Optimal sizing of rainwater harvesting systems for domestic water usages: A systematic literature review

摘要: Abstract Rainwater harvesting systems (RWHS) are increasing in popularity because of their ability to alleviate water pressure on centralized systems, minimize or delay rainfall runoff, and fit relatively easily both the centralized/decentralized infrastructure organization. Adequately sizing RWHS is critical optimizing operation under-sizing results that unable provide a sufficient, reliable source while oversizing increases capital costs incurred with limited marginal benefits poses potential quality risks. In this paper, we conduct systematic literature review assess state-of-art field optimization domestic rainwater systems. Sizing storage identified as most important objective optimization, yet for cost frequently implemented outcome optimization. Optimizing local maximum often favored over simulation-based methods produce global maxima. To derive more realistic estimates, future studies will have take into account greater variation demands well various climate change scenarios, especially given frequency quantity design variables system.
