I have been working with Jay Dee Contractors since 2018 on very large, complex, and challenging, multimillion-dollar GLWA collection system projects.  Whether it is building a crossover tunnel to connect nearly a century old 15’-6” interceptor to a 13’-6” interceptor or building other major flow regulating structures for the system, they have been adding significant long-term benefits to GLWA and the region. The team’s understanding of our complex system, innovative ideas, professionalism, and performance are commendable!
