Each customer will be charged a set water and sewer fee each billing period, no matter how much water is consumed. On your bill, you’ll see that the service fees are charged by the day which means if your billing period is 62 days long, the service fee will be slightly more; if the billing period is 57 days long, your service fee will be slightly less. Service charges help to keep our water treatment plants and pump stations running, even on days when you don’t turn on the faucet. These services have to be available at a moment’s notice, so even if you don’t regularly use these services, the system is still running and must be maintained 24/7.
