Public Works
The Lake Oswego Public Works Department is responsible for maintaining infrastructure systems throughout the City to ensure they are working correctly, efficiently, and that the life of our assets is maximized. Streets, Water, Sewer, Stormwater, Motor Pool and City Beautification maintenance programs make up the department with each responsible for their own infrastructure system.
Here at Public Works, we take pride in providing utility maintenance to help make Lake Oswego a great place to live.
News & Announcements
There is no such thing as a flushable wipe – even the ones that say flushable. “Flushable” wipes cause serious damage to sewer systems and homes because they don’t break down or dissolve, clogging sewer pipes, damaging equipment, and causing expensive repairs for homeowners and our public sewer system.
Do not flush wipes! The only items that should be flushed down the toilet are toilet paper and human waste. Other items, like wipes, should be thrown in the trash.
We want your help in making community streets a safer and more comfortable place. While staff work diligently on addressing issues that are spotted, we understand that we can’t catch everything.
Over the past five years, the City has been replacing outdated, manually-read water meters to a new, wirelessly-read technology. These smart meters support efficiencies in our water system and improve customer service.
As of spring 2025, 99% of the 12,630 meters city-wide have been replaced. The majority of these are residential meters, with about 300 accounting for commercial meters. All new smart meters are expected to be installed and in service by end of 2025.
