@fairychick:" There are lots of organizations that will help you. Your best bet for immediate help is a church or a local civic action group. Since you have an infant child, you will be considered the highest priority.
Unfortunately, utility companies typically won't turn something off unless you have failed to pay for quite a while and at that point they typically won't work with you on turning it back on without payment in full. You can call to ask the minimum payment required to restore service; sometimes this amount is the "past due" amount rather than the "total due" amount. You may also have to pay a restoration fee, which would be due immediately. Gather up the money you owe and pay them as quickly as you can. Once you are paid in full, make sure that you make a payment every month, as much as you can if you can't pay the whole bill.
All I would say is maybe borrow money from a bank or maybe family , do something extra on the side like for extra money . Cause unfortunately there's no other way . You could ask for an extension but that's not always guaranteed .
My water gets turned off every now and then , not cuz I dont have the money but because I forget about it cuz it's such a small bill , but when they do cut it off , I just go outside and turn it back on , and pay it if course .
Like others have mentioned 'You must pay balance once it has been shut off' Until your able to do that or receive assistance, maybe a neighbor can help you out with water and or baths for your children. Or stock up on some gallons of water from any store. Gallons of drinking water at my local Walmart are only .58 cents.
