Wastewater Treatment for the Cottonwood Community

The Cottonwood Water & Sanitation District manages the sewer collection system for wastewater discharged from Cottonwood customers.  The collection systems delivers the Cottonwood sewer volumes to a connection with the Arapahoe County Water and Wastewater Authority ("ACWWA").  Cottonwood contracts with ACWWA for the treatment of this wastewater.

ACWWA operates the Lone Tree Creek Water Reuse Facility located northwest of the Cottonwood District near Cherry Creek Reservoir and State Park. This state-of-the-art wastewater treatment facility also treats wastewater from the Inverness Water & Sanitation District. This plant operates in full conformity with all federal and state laws.

After treatment, the wastewater is discharged to Lone Tree Creek, a tributary to the Cherry Creek Reservoir.  Cottonwood is credited with the water volumes eventually delivered to Cherry Creek.
