Mission Statement

The Montana Water Environment Association (MWEA) is a non-profit organization dedicated to the preservation and enhancement of Montana’s water environment. The Association is committed to advancing science and education, disseminating technical information, increasing public understanding and promoting sound public policy in the water quality and water resources field.


Bioreactor-1MWEA as an organization, strives to provide and enhance the knowledge base of its membership and the general public at large with respect to water quality enhancement.

Specifically, the organization looks to promote research, encourage exchange of information and experience among its members, the wastewater collection and treatment industry, community leaders and the public at large.

This is primarily accomplished with the annual conference jointly held with MSAWWA and other sponsored technical sessions. The objective is to provide the highest quality conference and training achievable with the resources of its committees and membership at large and to recognize those in the industry for leadership and achievements.

The promotion of research and higher learning is encouraged with the allocation of scholarship funds and interactions with Universities and post Secondary institutions.

The association is affiliated with the Water Environment Federation as a Member Association. The objective of this affiliation is the smooth flow of information from the National organization and Member Association and the shared goal of enhancing water quality through education.

Lastly, the organization sets as one of its objectives, the maintenance of an adequate budget to support the activities to reach its other objectives via the intelligent management of any assets the organization secures with collected fees and contributions.
