INNOVATION IN WATER AND WASTEWATER TREATMENT PLANTS
To improve the drinking water quality for customers of the West Morgan East
Lawrence Water and Sewer Authority’s water distribution system in Hillsboro,
Ala., InSite Engineering designed an organic removal system with improved
sludge collection, increased particle settling, and membrane filtration that
would achieve compliance with tougher state and federal drinking water
regulations as well as increase water filtration capacity.
Spatial constraints at the existing plant site made expansion difficult. The 3D
modeling allowed for easy configuration of an extensive pipe gallery for the new
membrane filter building. Renderings and fly-throughs helped the client visualize
and understand the design intent. By creatively designing solutions using
Bentley PowerCivil and MicroStation, the project team overcame constraints
and completed the design of this $11 million project.

Alvarado Water Treatment Plant Expansion
San Diego, California, United States
The Alvarado Water Treatment Plant is one of three facilities that supplies San
Diego, Calif., with drinking water. In Phase IV of the expansion project, Archer
Western Contractors is installing a new ozone system that will increase the
output from 120 to 200 million gallons per day. The $65 million project includes
designing a 14,000-cubic-yard concrete structure, purchasing and installing the
ozone system, and all ancillary equipment and site work.
Archer used MicroStation, PlantSpace, AutoPIPE, and Project Wise Navigator to
convert the designers’ 2D documents into 3D models to coordinate all systems,
verify the design, and collaborate with subcontractors and vendors. An accurate
model with structural, mechanical, electrical, piping, and equipment details helped
prevent conflicts, enhance constructability, and forecast equipment issues.
