Running  toilets are the most common cause of high water bills, even though they  are not always the easiest to find.  The best way to check for a leak  in the toilet is to add a couple of drops of food coloring to the water  in the back tank of the stool.  Wait 15-20 minutes without flushing the  toilet, check the water in the bowl of the toilet.  If the water in the  bowl has changed color, then there is evidence that your toilet needs  repair.  This also may require several times testing to discover the  leak.

Your  bill will be calculated for water used during the previous two months.   At the top of your bill, next to your account number there is a  "Service From/To" with dates underneath.  Those are the actual service  dates.  Remember, if you fill up your swimming pool in July, you will  not get the bill until September.

Example:  January's bill is for November and December water usage, September's bill is for July and August. 

Water bill is due by 5th of each month.
