Water Quality

Testing data, compliance reports, and safety information for the WATCO community water system.

Water Safety

Your Water Is Safe

100% CDPHE Compliant

WATCO meets all drinking water standards set by the Colorado Department of Public Health and Environment (CDPHE) and the U.S. Environmental Protection Agency (EPA).

Regularly Tested

Over 100 individual water quality tests are conducted each year. Results are reported to CDPHE and summarized in the annual Consumer Confidence Report.

Alpine Source Water

WATCO draws from the high-elevation alpine watershed of the San Juan Mountains — one of the most pristine natural water sources in Colorado.

Licensed Operators

All treatment and distribution operations are managed by CDPHE-licensed operators Peter Coe (ORC) and Dean Jones, ensuring professional oversight year-round.

Where It Comes From

Source Water

WATCO draws from the high-elevation alpine watershed surrounding Alpine Lakes Ranch in the San Juan Mountains near Pagosa Springs, Colorado. At approximately 8,000 feet elevation, the source water benefits from natural filtration through granite and alpine soils, resulting in exceptionally low levels of contaminants before treatment even begins.

After collection, the water undergoes treatment — including filtration and disinfection — before entering the distribution system. The system is monitored continuously by licensed operators to ensure consistent quality from source to tap.

Source Protection

The alpine watershed is protected from agricultural and industrial contamination by its remote location and elevation.

Treatment Process

Water is filtered and disinfected with chlorine to meet all CDPHE standards before distribution to property owners.

Distribution Monitoring

Chlorine residual and pressure are monitored throughout the distribution system to ensure water quality is maintained to every tap.
