If you notice your water bill is higher than normal, contact Centennial Water customer service at cs@highlandsranch.org.

Request a leak assessment phone appointment by calling 303-791-2185 x3545. Before you do, here are some things you can check on your own before the phone appointment.

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 or zone valve malfunctions.
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 bibs/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 checks during a phone appointment:

1. They are assessing the water meter to see if it is showing flow when all faucets and fixtures are off.
2. They will give you some items to troubleshoot and explain how to read your meter.
3. They will ask if you have used the dye test to check all of your toilets for leaks. A dye test is performed using food coloring or a drink powder.
4. They will ask how your timer is set on your sprinkler system and how long you are watering each zone.

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.
