About Us
How do I start or stop my water service with Heights Water District?
Existing customers can transfer service within the District. New residents need to complete a service agreement and pay a deposit. To stop service, simply call our office to schedule a date and provide a forwarding address for your final statement.
What should I do if I need to shut off my water?
Most homes have a valve located beneath the water meter in the utility room. Closing this valve should shut off water to your entire home. If your valve is faulty or you need assistance, contact our office to schedule a service technician.
Who's responsible for leaking meter pits?
Homeowners are responsible for maintaining the meter pit in their yard. The District only maintains the actual meter inside the pit. Regular maintenance prevents damage to the water meter and potential charges for repairs.
Which parts of my water service line does the District maintain?
The District maintains your service line from the main water line to and including the curb stop on your property. Homeowners pay a monthly insurance fee for this maintenance. The section from the curb stop into your home, including the meter pit, is your responsibility.
Why does my water taste or smell unusual?
Taste or odor issues often stem from internal plumbing. Hot water heaters and water softeners are common culprits. Try cleaning sink screens regularly and temporarily bypassing your softener to see if this resolves the issue.
Why did my water bill suddenly increase?
Water meters only register actual water flow. As meters age, they typically slow down rather than speed up. A significant increase usually indicates a leak somewhere in your home. Check if the red indicator on your meter moves when no water is being used - this confirms a leak. Otherwise, it might have been a temporary issue like a running toilet.
Who should I contact about a water main break?
If you notice water surfacing on the street or near your home, call our office immediately. We have emergency personnel available 24/7 for such situations.
What does the door card about my non-functioning meter mean?
This notice indicates either your meter or its transponder has stopped working. Simply call our office to schedule a repair. The District covers these repairs at no cost unless damage resulted from neglect or tampering.
How do I restore water service after non-payment disconnection?
The District disconnects service for accounts 60+ days past due. To restore service, call our office to pay your past due balance plus applicable fees. Note that if service isn't restored before 8:40 pm, you'll need to wait until the next business day.
