What is the largest credit you received from your regular bills like?
This is one of those odd things that happens. Our water company is owned by the city. Our water district is a completely different organization in the next town over. Every year, we get a bill from the water district for about $220 in January. We pay it and the next month the district refunds the money to the city and its put into our water bill. The end result is that we have a huge credit balance for the first six months of the year. Odd, but they wont change it.
