PRWRF Water Quality Updates

SFWA is working in collaboration with the City of Santa Fe and the Santa Fe River Traditional Communities Collaborative to share water quality data from the Paseo Real Water Reclamation Facility. This page will be updated regularly with public resources concerning water quality, ongoing planning, and ways to get involved.

MORE INFORMATION ON PERIODIC SPIKES

After periodic water quality violations over the years, the facility’s UV system began failing in 2023. This is one of the main processes for sanitizing effluent but age of the plant makes obtaining new (or even used) parts extremely difficult. Replacing the UV system is estimated to take two years and cost several million dollars.

The Public Utility Department installed a chlorinate-dechlorinate process as a temporary fix to aid in the sanitizing process for reused effluent (chlorinated water cannot be released into a river course). SFWA is supporting our partners at the City as they research options for the design and construction of a new, state-of-the-art, climate-resilient water reclamation facility while also implementing short-term fixes for the interim.

Other information

Detailed Facility Report | ECHO | US EPA

2016 Facility Master Plan

CFU = “colony forming unit” (estimated viable bacteria cells in a sample, e.g. in 100 milliliters)

EPA E. coli Factsheet

E. coli is often used as an indicator species for other pathogens of a similar size that can be less reliable to detect. Fluctuations in the numbers are relatively normal because wastewater treatment relies on biological processes and can be impacted by factors such as storm events. However, high fluctuations can indicate the need for updated treatment systems.

Data shared here was collected and shared by the City of Santa Fe lab at the Paseo Real Water Reclamation Facility.
