Savanah Valley Utility District overcharging

Our SVUD Bill has been slowly creeping up but is $90 this month. Our actual water bill is $35 with the rest being sewer and sewer maintenance fees. How is the amount of water less than the sewer cost? If I'm only putting $35 worth of water into the sewer, why is my sewer cost so much higher? Why is there a separate fee for sewer maintenance? Shouldn't sewer and maintenance be one fee? I'm curious to know if all of the construction done in the last few years has increased all of the sewer fees. Do these developers pay for the sewer lines they put in or are we, SVUD customers financing this. I need to see an actual break down of money/ cost analysis. I will not be paying bills upwards of several hundred dollars so SVUD needs to solve this problem. It's time for some competition in the water, utility and cable departments. We are getting sucked dry as a community.
