Kirkland Signature Natural Spring Water

Kirkland Signature Natural Spring Water is a private-label product offered by Costco Wholesale Corporation. The brand was established in 1995 to provide high-quality goods at lower prices than national brands.

Because Kirkland Signature sources its water from various regional springs to minimize transportation costs and environmental impact, the specific manufacturing or bottling location depends on the geographic region where the product is sold. For example, in the United States, water is often sourced from local springs in California or Washington, while Canadian versions typically source from springs in British Columbia and Ontario. The packaging usually indicates the specific source for each bottle.

Kirkland Signature remains an exclusive house brand of Costco, which oversees the quality standards and supply chain management for the product globally. The brand has become one of the most successful private labels in the world, covering a wide range of categories from food and beverage to household essentials.
