Power, water and internet
Who to call to start service at a new address in Third Lake.
Power comes from Commonwealth Edison
Commonwealth Edison (Commonwealth Edison Co), an investor-owned utility, serves all of Third Lake. Its homes paid an average of 17.7¢ per kWh in 2025, about $107 a month (its average across Illinois, for customers on its standard service). Illinois lets you buy power from another supplier; 20% of Commonwealth Edison’s home customers do, and Commonwealth Edison still delivers it.
Service territory: HIFLD Electric Retail Service Territories (map dated Aug 2023). Prices and customers: EIA-861, 2025.
Water comes from Lake Villa water system
The Lake Villa water system supplies Third Lake: about 0% of residents live in its service area. About 100% of homes are outside any mapped community water system, most likely on private wells, which EPA doesn’t regulate. It buys treated surface water (EPA lists Lindenhurst and Central Lake County Jawa as sellers) and serves 8,829 people in all.
No health-based violations reported to EPA in the five years to October 2026, like 80% of the 5,012 systems serving 3,301–10,000 people.
The latest lead result on file, the 90th percentile of homes sampled in Jan 2026–Dec 2028, was 0.0 ppb, below the 15 ppb action level that applied. The highest in five years was 2.6 ppb. Results below detection are reported as 0, so 0 doesn’t mean no lead at any tap.
The system’s full record: EPA ECHO report
EPA SDWIS via Envirofacts (violations pulled Oct 9, 2026) and ECHO (lead samples, 2026Q3); service area: EPA Community Water System Service Area Boundaries v3.0. Violations are counted by the start of their compliance period. IL0970840.
