A program revitalizing water infrastructure
Facing EPA and state consent orders over wastewater overflows in their aging sewer system, the Metropolitan District Commission (MDC) launched the Clean Water Project to modernize infrastructure, safeguard public health and restore water quality for the greater Hartford region.
Enhancing treatment efficiency
Upgrades at Hartford’s plant use excess heat to generate nearly 40% of total electricity, lowering costs and reducing emissions.
Leveraging digital innovation
Using digital twins and real-time analytics, MDC now monitors performance and predicts risks to guide smarter planning.
Strengthening program management
Design, construction, finance and communications were coordinated to ensure seamless project delivery.
Together, MDC and CDM Smith are driving one of the nation’s most ambitious clean water initiatives, targeting completion by 2029. The program has already reduced overflows, enhanced system resilience and set a benchmark for sustainable water management. As MDC CEO Scott Jellison notes, “CDM Smith brings capacity. They bring their technical, financial and communications expertise, so they’re not just an engineering company.”
