Cheyenne Capitol Basin Storm Drain Assessment

The City of Cheyenne retained Ayres to determine the cause of odors associated with the storm drain system in the City’s historic downtown area. Ayres professionals trained in confined space entry entered an 84-inch storm drain to perform a condition assessment, document standing water or non-stormwater flow, take liquid samples, and remove debris encountered in the pipe. The project team also collected water quality samples from storm drains upstream.
