Water security is a critical issue that many policies aim to address, ensuring its protection and preservation in the face of future challenges caused by today’s global changes. The government has placed significant emphasis on safeguarding the Kingdom’s water security as part of Saudi Vision 2030, recognizing it as a vital aspect of the nation's broader security framework. This has been accomplished by establishing key indicators and targets, along with appropriate mechanisms to ensure the conservation and sustainability of water resources, particularly for drinking, for the benefit of future generations. The authority's pivotal role in ensuring the Kingdom's water security is reflected in its regulatory oversight, sustainable management of water resources, enhancement of service quality, strengthening of capabilities, promoting economic growth, fostering innovation and technology, and prioritizing environmental protection, all while adhering to phased responsibilities throughout the transformation process.
