What is the main purpose of water treatment systems?

The main purpose of water treatment systems is to purify water and make it safe for consumption. This involves a series of processes designed to remove harmful substances, bacteria, and chemicals from water sources, thereby ensuring that the water meets health regulations and is safe for human use. The purification process may include filtration, disinfection, and chemical treatment, which collectively help in achieving potable water quality.

While removing harmful contaminants is a necessary component of water treatment, the broader aim encompasses purifying the water itself to render it safe for drinking and other domestic purposes, which aligns perfectly with the choice provided. Other options, such as managing stormwater runoff and distributing water to consumers, are related tasks but do not pinpoint the primary objective of water treatment systems. These functions fall under broader water management strategies rather than the core purpose of treatment itself.
