Project Experience

Project Scope

Improvements to the Headworks and Wet Weather Flow Equalization at the Back River WWTP (Project or Sanitary Contract No. 918H) are intended to address storm water run-off where large quantities of precipitation during storm events can inundate the wastewater system, causing backups and overflows. The project will pump sewage from chronically backed up mains into the treatment plant and help prevent sewage overflows in the City. 

As a Sub-consultant to Louis Berger, Techno is providing quality assurance services including construction monitoring and inspection, daily reports, project records and documentation, contractor payment reviews, estimating and scheduling, submittal reviews and responses, RFIs and other contract documents.
