High Water Bill

If you notice your water bill is higher than normal, there are a few things you can do.

Contact Centennial Water customer service at cs@highlandsranch.org.

Request a leak check appointment. Before you call, here are some things you can check on your own before we come out to do our assessment. 

  1. Sprinkler system and drip systems – monitor the time watering in each zone and how often. Be observant of any obvious areas in the yard that are too wet and watch each zone run to make sure you do not have any broken sprinkler heads.
  2. Toilet leaks – Most toilet leaks are silent. You can check each toilet for leaks by using food coloring in the tank, 10 drops. When you return, if there is color in the bowl, you have a leak.
  3. Hose bibs – Check all of your outside hose bids/spigots for leaks.
  4. Hot water heaters – Check the area around the hot water heater to make sure there are no leaks.
  5. Water softeners – If a malfunction occurs, water softeners can constantly run water down the drain.
  6. Humidifiers – If there is an internal malfunction, a humidifier attached to your furnace can continually run. Humidifiers typically drains into the same place as the water heater.
  7. Reverse osmosis systems – If the psi or pressure is too low, or if the system does not shut off after the tank is full, the reverse osmosis system can run constantly.

What Centennial Water staff check for when we do a leak or pressure assessment at your home:

  1. Your water pressure, if your pressure valve (PRV) is failing, it can result in higher pressure and water usage. It should be set to below 70 psi.
  2. Your meter to see if it is showing flow when all faucets and fixtures are turned off.
  3. We leave dye tablets for you to check all of your toilets. You can use food coloring, 10 drops, or a drink powder, as mentioned above.
  4. The main shut off valve located in your front yard or driveway at each visit to ensure it is working properly. Also referred to as a curb box or curb stop. It is your point of connection to Centennial Water’s water distribution lines.

Water billing

Leak information


I had a water leak and didn’t intend to use the water. Why do I have to pay for this water?

Centennial Water requires all water meters be read every two months, and that each account be updated with the reading for the month. If the residence or business has experienced a water leak, it is up to the resident or business to repair the leak. Once the leak has been repaired, the customer can bring the receipt for the repair to Centennial Water’s customer service office. Staff will review the account and determine if an adjustment is due.

There are significant costs to produce clean water and deliver it on a continuous basis to your home or business. Therefore, any water that passes through your meter must be paid for.
