Welcome to GLWA Customer Outreach Portal

On January 1, 2016, the history of water and sewer service in Southeastern Michigan was forever changed. The once pie-in-the-sky idea of a regional water authority became reality when the three counties (Wayne, Oakland, and Macomb), the State of Michigan, and City of Detroit officially united to form the Great Lakes Water Authority (GLWA).


Wholesale customer collaboration within the Great Lakes Water Authority water and wastewater systems remains a top priority for the Great Lakes Water Authority. The outreach structure that has proved successful in the past will carry on with the Water Technical Advisory Committee (TAC), the Wastewater Steering Committee and related work groups. Wholesale customers and managers, operators and engineers of the GLWA will continue to address system planning and service issues through the outreach process. This portal is a resource for work groups and an information source for customers throughout GLWA's service area. To learn more about how to get involved in the outreach effort and use the portal, click on the green outreach toolkit bar to the right.



A series of videos and podcasts created to inform elected officials about GLWA and answer the questions most commonly heard through our service area.
