Atascadero Residents will more than likely see an increase in fees for their wastewater services. The Atascadero City Council voted yesterday to move forward with a plan to increase rates for sewer services. Wastewater treatment plant maintenance and funding for improvements are considered to be the driving forces behind the rate increase. The 19 percent increase will take effect in August. The last time Atascadero residents saw an increase in sewer rates was 1993.
