Because of the risks involved in high-maintanence water systems such as those developed by the ancient Romans in Jordan, such systems have been avoided by the country's indigenous population.  They preferred to rely on low-maintanence water sources - access to natural springs and streams, and re-use of ancient cisterns.  In addition, a limited amount of investment has been made in terracing and related earthworks.
