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
The Tryon Creek Wastewater Treatment Plant is aging and needs major upgrades to continue to reliably meet Oregon Department of Environmental Quality (DEQ) water quality requirements. Lake Oswego and Portland are exploring building a new wastewater treatment facility to replace the old plant.
The project is in the early stages of design. For more information about the project, or to sign-up for e-news, click here.
The City of Lake Oswego is updating outdated, manually-read water meters to a new, wireless-read technology.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 marked 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.
