City of La Grange issued the following announcement.
As a reminder to our customers, the City of La Grange will once again be doing the Winter Averaging of sewer rates. This will be based on your water consumption used during the months of December, January, & February. We will add the total amount of water consumption used during these months and divide by three. Each customer’s sewer bill will then be calculated on this amount for the next twelve months. Remember, if you have a leak, please repair it quickly, otherwise your sewer bill will be high for twelve months.
