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
To maintain public safety, the North Shore Road Bridge is closed to vehicular traffic until further notice. A temporary access route has been established over the bridge for people walking, rolling, and biking.
The City recently identified structural concerns with the retaining wall near the bridge. We are investigating the conditions of the retaining wall and conducting a structural analysis over the coming months. Long-term closure may be needed.
Please use alternative routes and keep North Shore Road for local traffic. We will keep you informed about the wall condition, updated timelines, and closure plans as we learn more.
The cities of Lake Oswego and Portland are exploring the option of designing a new, more efficient wastewater treatment plant to replace the existing Tryon Creek Wastewater Treatment Plant (TCWTP), which needs significant investments to meet necessary Oregon Department of Environmental Quality requirements.
Our water treatment plant has now received a chlorine delivery. Our call for a reduction in water usage is now lifted, but we can all still continue to use water wisely and not waste our precious resource.
Thank you, for doing your part to reduce water usage during our recent regional chlorine shortage. It really did make a difference.
The City of Lake Oswego is updating outdated, manually-read water meters to a new, wireless-read technology. These smart meters support efficiencies in our water system.
June 9, 2021 marks five years since the new Lake Oswego Tigard water system started providing high-quality drinking water to almost 100,000 customers throughout Lake Oswego and Tigard! Watch Lake Oswego Mayor Buck and Tigard Mayor Snider reflect on how important this partnership has been – and continues to be – for both communities. Let’s celebrate securing our most valuable resource for our cities’ future: investing in public health and preparing our cities for the long-term.
One of the most important things that a homeowner can do to save water is make sure that equipment is functioning appropriately and is efficient. The City offers free Water Audits to help citizens find ways to use less water. Water audits are performed during the spring and summer seasons when watering yards begin.
During your water audit, extra safety protocols will be implemented.
