Created in 1980 by the Townships of Ross, Richland, Barry and Prairieville, the Authority collects wastewater from over 2400 customers in northeastern Kalamazoo County, Michigan, using a network of over 50 miles of collector sewers, 36 pumping stations and associated trunk sewers. Wastewater is pumped to the City of Kalamazoo for treatment and final disposal. The Authority provides complete system management, maintenance, repair and upgrades.  The current service district consists of the Townships of Ross, Richland, Cooper, Village of Richland, and a portion of Charleston Township, plus the southerly portion of Barry and  Prairieville Townships in Barry County. 

 GLSWA is committed to preserving the environment, protecting the public health and safety while sustaining our wastewater utility system and its assets through the process of Asset Management and Community minded Level of Service goals.

We will collectively and proactively determine the importance / criticality of each functionally and financially significant (FFSA) asset, decide when to repair, replace or rehabilitate these FFSA assets and ultimately, evolve these improvements into a continuous Capital Improvement Plan (CIP) - a CIP that is adequately funded through rates set by the Municipalities' and Authority Board --allowing the Authority to achieve sustainability and to maintain a continual Level of Service (LOS) that protects the groundwater, public adjacent communities from potential negative impacts of the wastewater collection system, while effectively managing the long-term cost of operating those assets.

We will strive to maintain the highest-quality customer service in agreed to levels of service at the lowest life cycle cost possible.
