Olean city water and sewer bills will be going up again on June 1. Common Council approved a 1.5 percent increase in water and sewer rates to balance the requested $3.9 million water budget and $4.2 million sewer budget proposed for the 2019-20 fiscal year. Alderman noted that the city’s water and sewer infrastructure is more than 100 years old in many places and they are struggling to keep up with repairs and such.
