No, we do not bill in advance. We bill for water consumption that has gone through your meter. If for some reason we could not read your meter, i.e., snow is covering it, a dog is in the yard, your remote meter is reading the same as the previous quarter, etc., we may estimate your account if we have reason to believe the house is not vacant and there is not a valid reason for no consumption. We will base your estimate on your past history of water consumption. Your bill will state that it was estimated charges. Once we can get access to the meter your account would be adjusted for any differences.
