Welcome to Marshall Municipal Utilities. As a citizen of Marshall and a customer of MMU, you are part owner of a utility company. MMU is municipally owned, so you have a direct and personal interest in our business. As a municipal utility, we have several distinct advantages. Stockholders do not own our electric, water, wastewater, internet, and natural gas transportation utilities - the community does. Not paying dividends or making money for out-of-town investors helps us keep your rates low. Also, local control and management means we make decisions with your best interest in mind.
