Darwin has no town government of its own, so Inyo County runs its elections and most services, and its children attend Lone Pine Unified School District. Tap water in Darwin comes from Darwin Community Service District, which has a clean five-year EPA record (about 22% of systems its size had a health-based violation) and a latest lead result below detection.

Who to call to start service at a new address in Darwin.
Power comes from Southern California Edison
Southern California Edison (Southern California Edison Co), an investor-owned utility, serves all of Darwin. Its homes paid an average of 31.5¢ per kWh in 2025, about $149 a month (its average across California, for customers on its standard service). California lets you buy power from another supplier; 30% of Southern California Edison’s home customers do, and Southern California Edison still delivers it.
Service territory: HIFLD Electric Retail Service Territories (map dated Aug 2023). Prices and customers: EIA-861, 2025.
Water comes from Darwin Community Service District
Darwin Community Service District supplies almost all of Darwin. It draws ground water influenced by surface water and serves 40 people in all.
No health-based violations reported to EPA in the five years to October 2026, like 78% of the 11,392 systems serving <=100 people.
The latest lead result on file, the 90th percentile of homes sampled in Jan 2025–Dec 2027, was 0.0 ppb, below the 15 ppb action level that applied. Results below detection are reported as 0, so 0 doesn’t mean no lead at any tap.
