Potable

Detailed Definition

Potable water is water that is safe to drink and use for food preparation. It is free from substances that could cause harm to human health. Municipalities and other water providers must adhere to strict regulations to ensure water is potable. This typically involves analyzing the water for a wide range of contaminants and treating it to remove or reduce harmful components to safe levels.

Examples

Residential Development: An area considered for a new housing estate must have a reliable source of potable water. The developer needs to ensure the water supply meets all safety standards before proceeding.
Restaurant: A failure to provide potable water can lead to serious health issues, impacting the business’s reputation and possibly resulting in legal consequences.
Community Project: A rural area installing wells must test the water to certify it is potable before deeming it safe for local consumption.
