Summary

Sacramento County has 73 public water systems in the SAFER dataset. Of these, 22 (30%) are classified as Failing or At-Risk.

Those systems report serving 7,965 people. The county profile is also shaped by small systems: 38 systems serve 500 people or fewer.

4 systems are listed as Not Assessed, serving 907,419 people, so Not Assessed should not be read as a low-risk classification.

Reported funding since 2017 totals $168M across 4 systems. Technical assistance funding totals $1M.

System counts and reported population

Not Assessed systems make up 5% of listed systems and 56% of reported population. That population sits in a few large systems outside the SAFER assessment’s scope, which generally have more capacity, so this reflects scope rather than hidden risk.

Risk profile

Risk in Sacramento County is distributed across four dimensions. Water Quality contributes the largest share of the combined weighted risk score at 40%. Across all individual indicators, No intertie appears most often, affecting 49 of 69 assessed systems.

Patterns and context

The countywide totals hide important differences among systems. The panels below show how SAFER status varies by system size and service-area economic status, what conditions appear among Failing systems, and how reported funding is distributed across the 73 systems in Sacramento County.

Status by system size

SAFER status within each population group

Among systems serving 500 people or fewer, 17 of 38 are Failing or At-Risk. The highest concentration occurs among systems serving 501 to 3,300, at 71%.

Economic context
