Smart cities technologies can help improve water management, waste management, and healthcare. For water management, technologies like smart meters, leak detection sensors, and water quality meters can improve efficiency, reduce non-revenue water, and ensure adequate supply. For waste management, technologies such as sensor-based waste collection, GPS on trucks, and analytics can optimize collection and ensure waste is disposed of properly. For healthcare, technologies including electronic medical records, remote patient monitoring, and telemedicine can enhance access to care, improve outcomes, and reduce costs.
