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.

Smart Water Meter Project

The City is updating outdated, manually-read water meters to a new, wirelessly-read technology. These smart meters support efficiencies in our water system. 

We are replacing nearly 12,000 residential meters city-wide. More than 10,500 meters have already been installed on the northern and eastern neighborhoods of the city. In 2024, work will continue on the southside of the lake. Once residential meters have been installed, work will begin on commercial and multi-residential meters. All new smart meters are expected to be installed and in service by end of 2025.
