Kenya, as an important country in East Africa, has witnessed an accelerated urbanization process in recent years. The urban population has grown rapidly, and the demand for water resources has risen sharply. To improve the current situation of water supply management, the local water supply department in Kenya has introduced advanced NB-IoT smart water meter technology, which has enhanced the measurement accuracy, improved the meter reading efficiency, effectively saved a large amount of water resources, and reduced the operating costs of water supply enterprises.
