A sanitary survey is a comprehensive evaluation that focuses on the potential sources of contamination and the overall sanitary integrity of a water supply system. It involves assessing various aspects such as water sources, treatment facilities, distribution systems, and related infrastructure to determine any potential or existing contamination levels. This type of survey helps identify vulnerabilities that can lead to waterborne diseases and is crucial in ensuring a safe and reliable drinking water supply.

In this context, while other options like the hydrological cycle survey might assess water movement and availability, or an epidemiological study might focus on health impacts related to water consumption, these processes do not specifically concentrate on contamination assessment. Similarly, a water quality review would address the overall quality parameters but may not delve into specific sanitary concerns the same way a sanitary survey does.
