Colorado Springs Utilities is proposing an estimated $396 million first phase of wastewater-system expansion, including about 17 miles of pipeline and two lift stations. The utility projects its existing system could reach capacity by 2028 without expansion, and construction is anticipated from 2027 through 2030, according to a staff report to the Pikes Peak Area Council of Governments.
The Milton Proby Interceptor is the first of four planned wastewater-system projects. It would move wastewater to the Las Vegas Street Water Resource Recovery Facility and is intended to handle projected flows and loads, including from future development, while maintaining reliable service.
The project is expected to be financed through revenue bonds, customer base-rate revenues and cost recovery from new development. Developers are expected to contribute as new users connect, but the report does not quantify developer costs or the project's effect on customer bills.
The Community Advisory Committee voted unanimously on Sept. 30 to recommend the site application to the Pikes Peak Area Council of Governments Board. The board was scheduled to consider staff's recommendation to send the application to the Colorado Department of Public Health and Environment on Oct. 14, 2026.
