Rolling A WWTF - Dayton, Nevada Wastewater Treatment Plant

Rolling A WWTF is a municipal wastewater treatment facility located on Ferretto Parkway in Dayton, Lyon County, Nevada. The plant serves a population of approximately 6,500 people, placing it in the small-to-medium agglomeration category for inland communities in the western United States. As a US-based facility, Rolling A WWTF operates under the Clean Water Act's National Pollutant Discharge Elimination System (NPDES) permit program. Plants of this scale in Nevada are typically required to meet secondary treatment standards, with additional nutrient controls where receiving waters are sensitive. The facility's design and operation are overseen by state and federal environmental agencies. The plant discharges treated wastewater to a local watercourse that ultimately drains into the Carson River watershed. The Carson River flows through the Great Basin region, eventually terminating in the Carson Sink, a terminal basin. This inland system supports diverse aquatic life and is important for regional agriculture and wildlife habitat.

Rolling A WWTF discharges into a tributary of the Carson River, which flows through the Great Basin and terminates in the Carson Sink. The Carson River watershed supports riparian habitats, migratory birds, and endemic fish species. As a terminal basin, the system is sensitive to nutrient loading and water quality changes, making effective wastewater treatment critical for ecological balance.
