True or False: Cold water storage tanks should ideally be located away from sources of heat.

The statement that cold water storage tanks should ideally be located away from sources of heat is true. This is because heat can promote the growth of bacteria, including Legionella, which thrives in warmer water temperatures. Keeping cold water storage tanks in cooler areas helps maintain the water temperature necessary to minimize bacterial growth.

When cold water is exposed to heat sources, its temperature can rise above the safe threshold (typically above 20°C or 68°F), creating an environment conducive to bacterial proliferation. Therefore, strategically placing these tanks away from heat sources is a key measure in managing Legionella risk and ensuring that water remains safe for consumption.

In contrast, if cold water storage tanks are situated near heat-producing equipment or areas, it increases the risk of elevated water temperatures, leading to potential health hazards. This also emphasizes the importance of proper design and maintenance in plumbing systems to prevent Legionella contamination.
