Digital Twins in Water Infrastructure offers many benefits for smart cities automation, including lower energy consumption, improved operational efficiency, predictive maintenance, improved financial planning, improved smart cities performance data, and increased use of sensors. DIGITAL TWINS IN WATER INFRASTRUCTURE introduces the required intelligence into the basic smart cities blocks and helps it to become intelligent. Smart cities that have implemented Digital Twins in Water Infrastructure can be called smart cities that can control smart cities operations such as fire and safety, security, automate and control air conditioning, ventilation, etc. Smart cities uses sensors and microchips to collect and manage data according to functions. And the services of such infrastructure help the owners, operators and facility managers slow to efficiency and increase asset performance, reduce energy consumption, maximize space utilization, and minimize the environmental impact of smart cities. Systems must be designed to allow for maintenance and adjustments.
