Water bills are based on how much water is actually used. There are a number of different reasons that can contribute to a higher water bill. Watering the lawn or garden, additional occupants, and leaks can increase your water bill. The amount of days in the billing cycle can vary from month to month and occasionally there will be an extra week of usage.

Check your toilet. The most common and most costly water waste is from a leaking toilet. Have you heard your toilets refilling when not being used or does the handle sometimes get stuck? Sometimes there can be a leak that can’t even be seen or heard but a simple dye test can help determine if there is a problem. First, flush your toilet and after it fully refills put a few drops of food coloring in the back tank. Then, wait about an hour and see if any of the color comes down into the bottom bowl. If color shows up the flapper valve or plunger ball valve in the back tank may need replaced. Do this in each toilet in the house including ones that are rarely used.

If your toilet does not seem to be the cause there are several other possibilities that can account for higher usage. Be sure to check outdoor spigots and hoses, leaking faucets, hot water tanks, water softeners, ice makers, humidifiers or sump pumps that run on water back up. If none of these seem to solve your problem you may need to call a plumber or have your service line checked for leaks.

A delinquent notice will be mailed to the customer if the amount due on the account has not been paid in full by the due date of a regular invoice. Failure to pay past due balances may result in additional fees and the disconnection of water service. Receiving a regular invoice after a delinquent notice has been issued does not change the disconnect date indicated on the delinquent notice. Please notify Del-Co water of payments made toward delinquent accounts. Should the water service to a delinquent property be disconnected the delinquent account balance and all associated fees must be paid in full before water service is restored. Water service may not be restored the same day it was disconnected.
