Wass Gerke + Associates, Inc. is a certified small local business incorporated in July of 2001 by Dr. Roland Wass and Sara Gerke-Lieske. WGA specializes in planning, engineering design, construction, economic evaluation, and restoration of wetland and riparian areas in Arizona, Nevada, and southern California.  Mr. Martin Bressor is the CEO and serves as the primary business contact.

During the 10 years that WGA has been in business, we have been at the forefront of engineered treatment wetlands and ecosystem restoration efforts in the arid Southwestern United States.  Many of the projects WGA has completed were either “first” or used to develop design and operating criteria that were transferred to other similar projects.  Our expertise includes economic studies, risk assessments, planning and engineering design, and ultimately extends to the operations and maintenance phases.  WGA incorporates such knowledge into its design which often results in sustainable environments with lower lifecycle costs for the facility.

WGA has consulted on the planning, design and or operation of more than 25 wetland and riparian restoration projects in the United States and China.  Some noteworthy projects include the Tres Rios Flow Regulating and Overbank Wetland Design, The Rio Salado Ecosystem Restoration Project, Phoenix Reach, Dongli Lake Phase III, Tianjin, China, P.R., Camp Colley, City of Phoenix, AZ, Sulfur Creek, Laguna Nigel, CA, and a 100-acre Wetland, Riparian, and Mesquite Bosque restoration design on the Virgin River for the City of Mesquite, Nevada. These systems are located in both urban and rural environments and will or currently serve the role as platforms for water quality improvements, aesthetics, habitat enhancements, environmental education, and recreation.
