Customer Service & Support

The Customer Service section of Wastewater Management is responsible for accurately billing the agency's 160,000 customers for monthly SANITARY SEWER and annual STORM DRAINAGE charges. Sanitary sewer charges are billed in combination with Denver Water. Water and sanitary sewer charges appear on a single monthly bill. Storm drainage charges are billed separately, one time per year.

Our goal is to respond to customer inquiries in a prompt, accurate, and professional manner at all times.
