Flow from the Northern Treatment Plant is discharged to the South Platte River

The first flow from the Northern Treatment Plant (NTP) was discharged to the South Platte River at 2:00 p.m. on Tuesday, October 4, 2016.

The NTP is currently treating between four and five million gallons of wastewater per day, following completion of major construction activities in spring 2016 and functional testing of equipment throughout the facility.

Several months of start-up and commissioning activities were necessary to establish and test the biological treatment processes ahead of final completion of the NTP in early 2017. The efforts will ensure the new facility will not only meet or surpass all regulatory requirements but will do so in an efficient and cost-effective manner.

The NTP is an advanced wastewater treatment facility with capacity to treat 24 million gallons of wastewater per day and serve approximately 300,000 people. The facility was designed to support community growth in the northern metropolitan region for many years to come.
