Sustainable Water Distribution Strategy with Smart Water Grid

Abstract

Many problems that are encountered in regards to water balance and resources management are related to challenges of economic development under limited resources and tough competition among various water uses. The development of major infrastructure like airports in remote areas that have limited water resources is becoming a common problem. In order to overcome these difficulties, water management has to articulate and combine several resources in order to respond to various demands while preserving the ecological quality of the environment. The paper discusses the interest in implementing the Smart Water Grid concept on Yeongjongdo Island, which is the location of Korea's main airport. This new concept is based on the connection of various water resources and their optimized management with new information technology solutions. The proposed system integrates water generated through rainfall, external water resources (i.e., metropolitan water distribution system), gray water and other types of alternative water resources. The paper analyses the feasibility of this approach and explores interest in the Smart Water Grid concept.

Economic Dispatch Optimization of Multi-Water Resources: A Case Study of an Island in South Korea

“…It is the site of Incheon International Airport (ICN), currently the major airport in South Korea. As of October 2018, the population of this island was 72,939; its total area, including reclaimed land, is 116.8 km 2 , of which 14.9 km 2 is dedicated to agriculture, 35.9 km 2 to forest, 2.6 km 2 to parks, 0.7 km 2 to industrial zones, 7.4 km 2 to residential areas, and 15.3 km 2 to public spaces and other purposes [6]. The annual rainfall of the area is 1412 mm and the annual average air temperature is 12.5 • C. South Korea.…”

“…In recent years, due to global population growth and climate change, the global demand for water has increased [3,4]. Worldwide, water security issues have been rising and adding challenges and complexity to water authorities and water utilities for the continuous supply of water, and Korea is no exception [5,6]. The country's population has grown, industrialization has increased, and the uncertainties due to climate change have put increased pressures on limited available water resources, creating water use conflicts between stakeholders in Korea [7].…”

SWMI: new paradigm of water resources management for SDGs

“…And recently, information and communication technologies (ICT) have been applied to optimize the water production and distribution processes with maximum efficiency at each step (Byeon et al, 2015). Also, many research projects are ongoing to develop Smart Water Grid (SWG) technologies (Byeon et al, 2014) and apply the technologies to secure a sustainable water supply by connecting water sources and optimizing water treatment methods based on ICT in Korea (Choi and Lee 2013).…”

“…In such an approach, ICT solutions can play a key role for implementing the concepts of IWRM and achieving water sustainability (Byeon et al, 2015). Water management technologies converging with ICT have been called Smart Water Management (SWM) distinguished from traditional water management technologies.…”

A Study on Development and Application of Island Type Water Balance Evaluation System

“…A smart grid's functionality [9] will (1) enable active participation by consumers, (2) accommodate all production, distribution and storage options, (3) enable new products, services and markets, (4) provide water quality for the digital economy, (5) optimize asset utilization and operate efficiently, (6) anticipate and respond to system disturbances, (7) operate resiliently against attack and natural disaster. Figure 1 shows the strategic concept for securing water resources through improvement of water cycle as one of concept of smart water grid [7]. …”
