Dear Valued Customer,

Tualatin Valley Water District (TVWD), your drinking water provider, has completed the Alton St. Water Main Replacement Project, improving the water system serving your neighborhood.

The project included replacing about 500 feet of 2-inch PVC water main under SW Alton Street, between 18295 SW Alton Street and SW 185th Avenue, with a new 8-inch ductile iron water main.

To close out the work, Washington County inspected and approved the paving and restoration to make sure everything meets their roadway and public works standards.  

Benefits  
The previous main under SW Alton Street experienced multiple leaks in recent years.

With these improvements now in place, you can expect several direct advantages as a result of this important infrastructure upgrade, including:
  • Continued Water Quality: The new main will help keep your water clean, safe, and flowing the way it should.   
  • Reduced Future Disruptions: By replacing aging mains, the chance of future leaks, breaks, or unexpected shutoffs are reduced.   
  • Stronger Fire Flow: It also strengthens the water supply needed for firefighting, helping protect your home, business, and neighborhood.  
This water system improvement, funded through water rates, demonstrates our commitment to providing high-quality water service for you and your neighbors.
