What is a Secondary Source of Supply?

A secondary source of supply refers to any alternative water source that is used in addition to the primary public water supply. This can encompass a variety of sources, such as wells, cisterns, or surface water that can supplement the primary supply system, especially during times of high demand or when the primary source is compromised.

This concept is important because having a secondary source ensures greater resilience in water supply management. It allows water utilities to mitigate risks associated with service disruptions, changes in water quality, or increased consumption patterns, ensuring continuous access to safe and sufficient water for the community.

While a backup water treatment facility might play a role in emergency scenarios, it specifically pertains to infrastructure rather than water sourcing. Other options like distributing bottled water or agricultural irrigation point to specific uses or scenarios that do not fully encapsulate the broader definition of a secondary supply as an alternative source of water. Thus, the description as an alternative water source accurately reflects the comprehensive view of what constitutes a secondary source of supply.
