The cost of your water bill will depend on the State and city you live in and how much water you use.
Different Cities and States have different water rates.
Plus there's the added cost of the sewer bill and most charge you another fee per 1,000 gallons of water going down the sewer and some places have a flat sewer rate.
My water bill a long with my sewage bill is $50.00 per month.
Your water bill might be the same, could higher or even lower depending on where your at.
And your water department will likely require a deposit to get your water service turned on.
