If you live in the City of St. Peter, your water rates will be going up starting next week. The St. Peter City Council has approved a plan to be implemented over the course of a year and a half that will change the ways in which the amount of water used is rated. St. Peter city officials say that smaller households can expect to see an increase of a little over $3 a month for water starting April 1st. If your household is a larger water user, you may see up to a $5 increase. Future increases will also occur on August 1st and December 1st of this year, as well as August 1st next year.
