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
As leaves fall, storm drains can get blocked by debris, leading to localized flooding. These drains are vital for keeping streets and sidewalks clear of excess rainwater as well as maintaining stormwater quality standards. Simply clearing leaves and debris from the surface of catch basins near your property with a broom or rake can keep the drainage system functioning well.
The City has a limited number of free drop boxes available to support neighborhood clean-up events through a contract agreement with Republic Services. Neighborhoods can apply for a free drop box to help collect neighborhood leaves.
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.
Clean drinking water is an essential resource we rely on every day. Providing residents and businesses in Lake Oswego with safe, dependable, high-quality water is our top priority.
Lake Oswego’s tap water meets or exceeds every State and Federal standard for safe drinking water. Get to know your drinking water by reviewing the latest 2025 Water Quality Report.
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Over the past five years, the City has been replacing outdated, manually-read water meters to a new, wirelessly-read technology.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.
