Joint Water Purification Plant ("JWPP")
The Cottonwood District joined with Arapahoe County Water and Wastewater Authority ("ACWWA") to construction the JWPP. This facility uses reverse osmosis, and micro-filtration methods to treat renewable water from the Cherry Creek alluviam. Without treatment, the District's Cherry Creek water rights are limited to non-potable irrigation use. This facility reduces the Districts dependence on non-renewable deep well aquifers and provides high quality water for customers.
