Denver Metro Wastewater Reclamation District Northern Treatment Plant Program

As part of its goal of expanding wastewater service to existing and future customers in the northeast portion of the metropolitan Denver area, the Metro Wastewater Reclamation District embarked on a $475 million capital improvements program called the Northern Treatment Plant (NTP) Program. The NTP Program consists of four projects: the reclamation and preparation of the treatment plant site; the design and construction of a 24-mgd wastewater treatment facility; a 7-mile gravity interceptor; and an 11-mile pressurized force main.

Over a 8-year period, Carollo served as the Owner’s Advisor for the NTP Program. In this role, the Carollo team provided comprehensive program management and engineering services including planning, procurement, and facilities implementation. This strategic partnership rendered resources, expertise, and on-site representatives as an extension of District staff. Key areas in which the Carollo team provided support included:

• Program-Wide Planning: Developed a program vision and goals, including program management and operational strategies.
• Project Delivery Analysis: Evaluated different project packaging and delivery methods with District staff to identify the most appropriate method for each project within the NTP Program. Selected delivery approaches included design-bid-build and progressive design-build.
• Program Controls: Developed systems for monitoring budget and schedule; assigning and monitoring risk, and validating design-build GMPs; and assisting with implementation of the Owner’s document control system.
• Conceptual Design: Developed design definition for all aspects of the Program’s projects.
• Communications Support: Assisted the District with execution of their Communication Plan, including assistance with internal and public outreach.
• Land and Easement Acquisition Assistance: Assisted the Owner with the purchase of land and easements necessary for construction of the NTP and associated pipelines and developed a tool for tracking the status of individual parcels.
• Permitting: Provided planning and permitting support for the treatment facility and transmission systems and developed tools for tracking the status of individual permits.
• Business Integration: Prepared a management and business planning for the integration of the satellite facility into existing District organizational and operating procedures.
