The department helps improve water quality and works with individuals, businesses and municipalities to ensure they have the tools and knowledge to develop sustainable practices that protect Missouri’s water resources. We provide financial assistance to help communities plan, finance and build water and wastewater infrastructure projects that improve the lives of Missourians; provide financial assistance to projects to ensure adequate, long-term, reliable public water supply, treatment and transmission facilities; and award grants to assist regional public comprehensive planning organizations and interstate organizations to carry out water quality management planning.
