Hilyard Pipeline Project Update

Water Resiliency Projects

August 28, 2024

Dear Neighbors,

This summer, EWEB successfully completed the current phase of Hilyard pipeline construction and transitioned customers to the new water system. The work included constructing a 36-inch water transmission pipeline and replacing a 24-inch storm drain from the intersection of Patterson Street and E. 40th Avenue, down Hilyard Street to 33rd Avenue.

In addition, EWEB contractors performed temporary street repairs, allowing this heavily used stretch of Hilyard Street to be fully re-opened to vehicle traffic. These repairs will keep the road safe and passable until the City of Eugene begins its permanent paving project later this year. Visit the City's projects page for more information and updates about this City-led public works project.

Next phase of work

Expect traffic impacts on E. 40th

With the primary section of the Hilyard pipeline now operational, EWEB is preparing to move forward with the next phases of this essential infrastructure upgrade.

Starting this week, EWEB will begin replacing the main water pipeline beneath E. 40th Avenue from Patterson Street west to Mill Street. The existing 6-inch cast iron pipe, installed in the 1950s, will be upgraded to new 12-inch ductile iron pipe. The smaller service pipes that connect to homes and buildings will also be replaced. The work is expected to take approximately 14 weeks and may cause temporary traffic delays in the area shown below.

Looking ahead

Pipeline work in south Eugene will continue into 2025. EWEB will extend an existing 12-inch main along Dillard Road from Hilyard to Fox Hollow, and connect the new Hilyard pipeline to another connection point near 34th and Hilyard.

This will be the final phase of an almost 10-year project to connect together multiple reservoirs and pump stations for redundancy, resiliency, improved water quality, and to allow EWEB to retire and replace aging infrastructure in the area.
