We couldn't fully map which utility serves Redwood. These numbers come from the utilities we matched, which serve about 37% of residents.
Our data comes from public records and is still incomplete. Many utilities don't publish every number, so we're adding more all the time. Your city's range is a starting point: testing your own tap is the only way to know exactly what's in it.
