Galveston Main Wastewater Treatment Plant - BEI11-0014
In this video, Jeffrey Peters of CDM, discusses the project Galveston Main Wastewater Treatment Plant in the Innovation in Water and Wastewater Treatment Plants category. Located on a barrier island off the Texas Gulf coast, Galveston was devastated by Hurricane Ike in 2008. The extended storm surge caused a major portion of the public wastewater facilities including the 10-million-gallon-per-day Main Wastewater Treatment Plant to fail to function. Design of the $60 million project to rebuild the plant was completed in less than a year to help ensure federal block grant funding eligibility. The scope included modifying screening structures; rebuilding an influent lift station as a submersible pump station; rebuilding the grit-removal system; replacing aeration basins, air diffusers, and blowers with a sequencing batch reactor; converting the disinfection system to ultraviolet disinfection; constructing an intermediate pump station; and modifying the solids dewatering building. CDM constructed a 3D/4D model of the seven facilities using original drawings and field surveys. Intelligent modeling drove the integrated design process from front-end engineering and design through phased construction. ProjectWise facilitated management of more than 8,800 documents for 162 team members in 22 offices. Using 3D/4D models shortened client and regulatory review time by 25 percent and reduced design time by 30 percent.
