SOUTHWOOD Lead Service Line Inventory
SOUTHWOOD serves about 64,155 people in Washington state. Like all US water systems, it's required by law to maintain an inventory of lead service lines—the pipes that connect homes to the water main—and to replace them over time.
What we know about SOUTHWOOD's lead pipes
SOUTHWOOD has not yet reported data on how many lead service lines exist in its system. This doesn't mean there are no lead lines; it means the utility either hasn't completed its inventory or hasn't shared the results publicly yet.
Lead service lines are a real concern. If your home was built before the 1980s—especially before the 1950s—there's a meaningful chance your service line contains lead. When water sits in lead pipes overnight or for several hours, small amounts of lead can dissolve into the water. This risk is higher in homes with older plumbing and in areas with corrosive water.
What you should do now
Contact SOUTHWOOD directly. Ask them three things:
1. Does my property have a lead service line? 2. If yes, what's the replacement timeline and cost? 3. What's the current water pH and corrosion control status?
Your utility may have partial or complete data even if they haven't published it yet. They can often tell you whether your specific address is at risk based on construction records or previous testing.
Reduce lead exposure while you wait
If you're concerned about lead in your tap water (whether from a service line or internal plumbing):
- Use cold water for drinking and cooking. Hot water leaches lead faster.
- Flush the line. Let water run for 30 seconds to 2 minutes before using it, especially first thing in the morning.
- Test your water. Many health departments offer free or low-cost lead testing.
If you have young children or are pregnant, contact your doctor or the CDC for guidance on lead exposure.
Next steps for residents
- Call or email SOUTHWOOD to ask about your address and their replacement plan.
- Request a free water test from your local health department.
- If your service line is confirmed lead and replacement is unavailable soon, use cold water for drinking/cooking and flush before use.

Frequently asked
How do I know if I have a lead service line?
Contact your water utility with your address—they keep records of which properties have lead lines. You can also have a plumber inspect your meter pit or internal pipes, though the meter pit inspection is more reliable. A magnet test on the exposed pipe works: if a magnet sticks, it's steel (not lead).
Is lead in tap water dangerous?
Lead is a neurotoxin with no safe level of exposure, especially for children under 6. Even low levels can affect brain development. Talk to your doctor or pediatrician about your specific situation and whether testing or water filters are recommended for your household.
How much does it cost to replace a lead service line?
Costs vary widely but typically range from $3,000 to $25,000+ depending on your home's location, depth of the line, and soil conditions. Many utilities offer assistance programs or cost-sharing. Ask SOUTHWOOD about their replacement program, rebates, or financing options.
Can I use a water filter to remove lead?
Some filters work: NSF-certified filters for lead are effective, but they require regular replacement and maintenance. Filters address tap water only, not the source problem. For a long-term solution, replacement of the lead line is the only permanent fix.
