Fall/Winter 2022 13 Project Scope The North System Renewal Program is one of the long-term planning projects that allows Denver Water to meet the demand needs of a growing population while also meeting current and future water quality regulations. While Denver Water has put plenty of capital dollars into expanding and upgrading the 80 year old Moffat Treatment Plant, it can no longer be upgraded, and its location limits the ability for expansion. The North System Renewal Program is a three phase, $600 Million program, that will replace and repurpose North System facilities that were constructed in the 1930s. Planning for the project began in 2010. In 2016, the project commenced with the construction of an 8.5-mile pipeline from Moffat Treatment Plant to Ralston Reservoir. While the pipeline was under construction, Denver Water started the second phase of the project. In 2018 Denver Water, their Owner’s Representative Jacobs Engineering/CDM Smith, and their CMAR contractor Kiewit Corporation broke ground on the new, state of the art, NTP. In early 2021, initial work to repurpose portions of the Moffat Treatment Plant as a storage and distribution facility for water treated at the Northwater Treatment Plant was initiated. Northwater By the Numbers The NTP is the largest construction project Denver Water has undertaken in many years. Replacing a plant that was originally constructed in the 1930s with a facility that is easily expandable, can handle the demands of changing regulations and respond to climate change is an immense undertaking. Here’s the NTP by the numbers. • $520 Million – Construction budget for the NTP • $80 Million – Cost of pipeline construction • 183 – Acre plant site • 150 – Million Gallons per Day build out capacity • 75 – Million Gallons Per Day initial capacity • 100 – Years expected lifespan of the NTP • 2024 – Anticipated completion in February 2024 • 31 – Separate bid packages for construction under the Kiewit CMAR contract. • 16 – Structures on-site • 2 – 10 million gallon clearwells One of the most innovative and sustainable processes that Denver Water has implemented during this project is the “Close as You Go” process. This system allows for individual parts of the project to be closed out at the time of completion instead of waiting for the entire project to be completed. The process includes walk throughs and creation of punch lists, completion of drawings of record and release of retainages.
