Volkert designed a new 1.25 mgd (million gallons per day) wastewater treatment facility for Diamondhead Water and Sewer District in Diamondhead, Mississippi. The treatment facility has the hydraulic capacity to treat up to 7.5 mgd during heavy rains and wet weather events.
During the first phase of the project, Volkert designed a subsoil “wicking” system and preloaded the site to stabilize the soils for construction.
Construction included the installation of over 650 driven piles to support the various facilities and was constructed above the 500-year flood elevation. The 20” outfall, constructed in the Jourdan River, included a 600’ bore under an interstate and a 500’ bore under a sensitive archeological site to avoid disturbance. Tide flex diffusers were incorporated into the outfall.
A centralized Supervisory Control and Data Acquisition (SCADA) control room monitors the performance of all process equipment located on the site, as well as 11 pump stations located off-site.
Volkert provided electronic operations and maintenance manuals with on-line training modules geared to the specific equipment being utilized at this site.
Construction was completed 50 days ahead of schedule.
