EPCOR - TIERRA DEL RIO Lead Service Line Inventory

About This Water System

EPCOR - TIERRA DEL RIO serves 4,868 people in Arizona. The system draws water from groundwater sources.

Lead Service Line Inventory Status

This water system has not yet completed a lead service line inventory. That means the utility has not yet surveyed and documented which homes are connected to the water main through lead pipes—or confirmed that homes use safer materials instead.

Under federal law, all US water systems must complete this inventory by October 2024. If your system hasn't finished, it should be underway now or completed very soon.

Why This Matters

Lead service lines are the most common source of lead in drinking water. Even in systems where the water itself is treated properly, lead can leach from old pipes into your home's water. Children under 6, pregnant people, and breastfeeding mothers are most vulnerable to lead's health effects.

If your home was built before 1986 (when lead pipes were still legal), there's a higher chance you have a lead service line. Older homes built in the 1950s–1970s are at greatest risk.

What Happens Next

Once this utility completes its inventory, it must:

• Publish the results publicly
• Identify which homes have lead service lines
• Create a plan to replace those lines
• Notify affected residents

The federal government has set funding aside to help pay for replacements through the Infrastructure Investment and Jobs Act, though the amount your system receives depends on factors like system size and need.

Take Action Now

You don't have to wait for the inventory to get answers about your home.

Contact EPCOR - TIERRA DEL RIO directly and ask:

• Does my address have a lead service line?
• When will the inventory be complete?
• What's the replacement timeline?
• Are there any water quality test results available for my area?

You can also request a free or low-cost water test through your county health department if you're concerned about lead at your tap.

Next Steps for Residents

• Call your utility and ask for your home's lead service line status
• Use a water filter certified for lead (NSF/ANSI 53) if you're concerned while waiting for inventory results
• Talk to your pediatrician or contact the CDC if you have health concerns about lead exposure
• Check back here for updates once the inventory is published
