(Juneau) The Juneau Common Council Tuesday night approved an increase in sewer rates for residential, commercial and industrial customers. The monthly service charge is increasing based on the size of the water meter. So, for example, customers with the smallest water meter will see their monthly service charge increase three dollars to $18.80. The largest sewer customers will see an increase of around $500 to $1524. In addition, the volume charge per-thousand gallons is increasing 57-cents to $6.71. The rate increase will take effect in the next 90 days.
