The source of water of Timoga Springs comes from Lake Lanao in Marawi City, Lanao del Sur—which is 37 kilometers away. Lake Lanao waters come from a volcanic source, the lake being the crater of an extinct volcano. These waters are filtered underground in the Timoga, Buru-un area of Iligan, making it one of the richest source of fresh, high-pH, alkaline mineral water.
