The Marshall Fire devastated areas around Town of Superior, Colorado (“Superior”), and several thousand surrounding acres. Superior’s raw water reservoir was significantly affected by ash and debris. Following the fire, the municipal water supply suffered from substantial taste, odor, and color issues, which led to consumer complaints and quality concerns throughout the community. Superior needed to quickly find a solution to mitigate these water-related and consumer confidence issues [1, 2, 3].
A permanent granular activated carbon (GAC) adsorption system was planned, designed, and installed as part of the drinking water treatment plant within 4 months of initial concept.
After the GAC system was commissioned, Superior residents did not express any more complaints related to the taste, odor, and color of their drinking water. With a maximum flow rate of about 3,000 gpm, the GAC system is able to effectively produce high quality drinking water for a community of 15,000 people.
