Water Infrastructure

Water infrastructure and treatment have a substantial impact on our environment. According to recent studies, the average person cites our ability to preserve our environment and provide clean drinking water as among the most serious problems facing the world in the future.

TWM is a recognized leader in water and wastewater engineering. Whether a client has questions about regulatory compliance, advancing technology, or environmental responsibility, whether their aging infrastructure is in need of repair, rehabilitation, or replacement, TWM can help. Our approach to every project is focused on cost savings, sustainability, and long-term value.

Our firm has provided facility planning and design services for a wide range of projects throughout the St. Louis area and the Midwest meeting or exceeding EPA standards, NPDES permit limitations, and client demands for innovation, for a balance between initial and life cycle costs, and for ease of operation and maintenance. Many of the treatment plants designed by TWM have been nominated as an EPA Plant of the Year. And we have similar expertise in the design of wastewater interceptors, collection systems, lift stations, the separation of combined sanitary and storm sewer systems (CSOs), water towers, and water distribution systems, and in securing and managing grants and loan funding for our clients.

TWM helps our clients navigate the potential minefields of regulatory compliance and project financing by tapping into the wisdom we have accumulated through more than 40 years of interaction with the federal, state, and local agencies governing environmental projects.
