What type of water is termed as Domestic Supply?

Domestic supply refers to the water that is necessary for the typical needs of households and businesses. This includes not only drinking water but also water used for cooking, bathing, cleaning, and other essential daily activities. The term encompasses a broad range of uses that a residential or commercial establishment would require, signifying its crucial role in supporting the health and hygiene of the community.

In the context of the provided options, the focus on residential and commercial use aligned with the definition is what makes this answer accurate. While the needs for fire protection are important, they do not encapsulate the wider variety of uses encompassed by domestic supply. Similarly, water distributed solely through public utilities or intended for industrial purposes does not align with the broader definition of domestic supply, which is fundamentally about meeting the everyday needs of the population. Hence, defining it as water required for residential and commercial use captures the essence of what domestic supply entails.
