INNOVATION IN wATER AND wASTEwATER TREATmENT PLANTS
galveston Main wastewater treatment plant
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. project Wise
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.
