Great Oaks Water Company bills its residential customers every two months, so the typical customer will receive 6 bills per year.   This is an example of a Water Bill based on a standard 3/4" x 3/4" single-family residential meter and a two month billing period (54 - 66 days).  Your actual bill might differ for many reasons.
