Twin Cities WWTP Upgrade

This Design-Bid-Build project involved a complete replacement of the aging lagoon-style wastewater treatment system serving the Towns of East New Market and Secretary, Maryland. The scope included the construction of a new Sequencing Batch Reactor (SBR) process, a headworks building with advanced screening and grit removal, a new raw sewage pumping station, and aerobic digesters with 24-hour storage and equalization tanks constructed using prestressed, post-tensioned concrete. Additional improvements included a new UV disinfection system, a solids dewatering and handling system, upgraded electrical service, emergency generator replacement, and a fully integrated SCADA and HMI plant control system.
