Integration Model for Smart Water Management Systems: A Systematic Literature Review

The concept of smart water management (SWM) encompasses a series of technologies and systems whose objective is to deliver a sustainable, efficient and quality water supply service for customers. However, it is necessary to deepen the discussion about how this diversity of applications can be integrated into an architecture. This article aimed to identify the basic structure of integration models for smart water management systems (SWMS). For this, a systematic literature review was carried out in the Web of Science and Scopus databases, resulting in 20 integration models selected for final analysis and having their characteristics detailed in the results section. The main findings of this article were the similarities of the models studied with the functional model proposed by ISA-95; which can be categorized into the layers field devices, middleware and applications and adding the cross-cutting security and management. However, the detailing and systematization of the information flow in a SWMS model represents an opportunity for future research, as well as the inclusion of aspects related to sewage and rainwater in the integration models to complete the concept of the natural water cycle.
