Communities supplied with tap water from NWC are considered to be almost entirely reliant on desalinated water (e.g., Rehovot). At the same time, there are still several large cities (e.g., Kfar-Saba) and a number of small settlements that are primarily supplied by local well water. . Desalinated water is not suitable for direct use as it is prone to corrosion and has adverse effects on human health and the environment. Re-mineralizing desalinated water to control its pH, alkalinity, and hardness is considered an important step in post-treatment .
