Abstract: The global increase in demand for water, due to population growth and industrialization, puts heavy pressure on the scant available water resources through overuse and contamination. But how efficient is the world in conserving it?. Saving water is now a collective responsibility. In this age of scientific advancements, using technology to solve environmental problems would contribute in making the Earth a better place for all living beings. Thus, this research examines the frontier innovations poised to rewrite the future of global water security. It explores various methodologies of water conservation. The topics covered in these papers include the employment of IoT technology, PLC (Programming Logic Controllers) based monitoring device, Sensor technology, Transmission cloud and Optoelectronic device.

It emphasizes improvement in water efficiency in petrochemical industry that influence water conservation, a real-time monitoring of water conservation, a conservancy project, a mobile app to regulate water pumps, smart metering, municipal pipe networking, sediment variation, water consumption proportion. The research also investigates the effects of water conservation on the environment and suggests an information architecture. It addresses the importance of water conservation and the methods to evade disasters like flood and also the effective ways to overcome challenges such as water scarcity and water contamination.

Keywords: IoT Technology, Optoelectronic device, Wireless sensor networks, PLC (Programming Logic Controllers), Smart metering.
