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).

Water comes from Round Lake Beach water system
The Round Lake Beach water system supplies Long Lake: about 26% of residents live in its service area. Round Lake Heights serves another 9%. About 64% 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 Central Lake County Jawa as seller) and serves 27,200 people in all.
No health-based violations reported to EPA in the five years to October 2026, like 83% of the 3,525 systems serving 10,001–50,000 people.
The latest lead result on file, the 90th percentile of homes sampled in Jan–Dec 2025, was 4.6 ppb, below the 15 ppb action level that applied. That’s higher than 89% of similar systems’ latest results.
