The largest drinking water storage facility is the Riyadh Strategic Water Reservoir, with a total capacity of 4,790,000 cubic metres, located in Riyadh, Saudi Arabia, and verified on 22 September 2023.

The decision to construct the 4,790,000m³ SWCC's Riyadh Strategic Water Reservoir facility is motivated by the imperative to mitigate water scarcity and ensure a dependable water supply for Riyadh. This facility plays a crucial role in augmenting the economic value of desalination through renewable energy, such as solar desalination, by storing surplus desalinated water for consumption during periods when energy sources are unavailable. By setting a new record for the world's largest drinking water storage tank facility, the project addresses the escalating water demand, fortifies water security, and establishes strategic and easily accessible water reserves. The record-breaking achievement is evaluated based on the facility's storage capacity, comparing it to similar facilities worldwide.
