Abstract
Water pollution is a major issue all over the world, and one of the great causes of water deterioration is industrial waste as the polluted water is being dumped into surface water such as seas, springs, and dams. Consequently, this will affect the whole planet, starting from destroying the agricultural crop up to the endangerment of humankind. There are plenty of industries all over Saudi Arabia, many of which are of a high category that generates dangerous fluids and other materials in their daily production activities. By discharging polluted components in water, the industry is considered to be violating the General Authority of Meteorology Environmental Protection (GAMEP)’s laws and regulations. It’s a revolutionary step to stop establishments and industries from contributing to water pollution. Currently, industries violating these laws are difficult to identify due to the manual nature of measuring industrial water tanks. This produces difficulties in pulling out a sample to measure. To tackle the aforementioned issue, a system has been proposed as it is not only detecting water pollution but will take action in order to prevent the continuation of water pollution. The integration between two technologies has been introduced in this system. First, IoT (internet of things) is used to measure water components in industrial tanks and detect any violation. Second, blockchain is applied to the appropriate penalty of the violating industry and maintain the transparency, integrity, and reliability of the violation records. The system will be capable of measuring water quality in real-time and facilitate the instant detection of any violations to carry out the appropriate penalty. An introductory experiment shows prominent results that can be used to decrease the number of water violation cases to save the planet and secure a promising future.
