Explanation:

Greywater use involves using water from sources like sinks, showers (excluding toilet water) for non - potable purposes (e.g., irrigation). To safely use greywater and prevent contamination of potable water systems, it requires a separate plumbing system. Water reclamation is a broader process that may not always need separate plumbing, and desalination is about removing salt from water (usually for large - scale or industrial/potable use) and doesn't inherently require separate plumbing for its core process.

Answer:

C. greywater use
