Kirkland Signature spring water

Kirkland Signature Spring Water is the primary private-label bottled water brand for Costco Wholesale. The label visible in the image features bilingual text (English and French), which is characteristic of products sold in Canada, identifying it as 'Spring Water / Eau de Source'. The Kirkland Signature brand was launched in 1995 to provide high-quality items at lower prices than national brands.

The water is sourced from various protected springs and wells depending on the region of sale. In North America, the manufacturing and bottling are typically handled by third-party suppliers such as Niagra Bottling, LLC. This localized sourcing strategy helps the company maintain sustainability and reduce transportation costs. Ownership remains with Costco Wholesale Corporation, ensuring the brand stays exclusive to their warehouse club members and online marketplace.
