Little Patuxent WRP Expansion CMAR
"If I got a call from anybody in the industry, any of my peers in water-wastewater, I would tell them that this has been the best construction project I've been involved in in 33 years."
The Little Patuxent WRP upgrade increased the plant’s capacity and improved treatment performance to achieve enhanced nutrient removal (ENR). Facilities constructed included a grit and screenings facility, primary and secondary clarifiers, aeration complex, solids handling, denitrification filters, and UV disinfection. The plant-wide modifications required detailed sequencing of tie-ins, testing, and commissioning to allow continuous plant operation throughout construction.
Ulliman Schutte, in a JV with Clark Construction, was selected as CMAR in a two-step process at the 20% design stage, allowing us to be heavily involved in design development. Informal, “real-time” estimates helped the team evaluate various design options. Preconstruction services also included Ulliman Schutte's best-value equipment procurement process and intricate Maintenance of Plant Operations (MOPO) planning to ensure continual flow treatment. The team environment allowed these services to be performed as a seamless process with complete collaboration and transparency.
