The Water Collaborative Delivery Association is a leading professional association dedicated to helping the water and wastewater industry deliver Better Projects, Together through successful collaborative delivery solutions. Collaborative delivery methods include all approaches to procuring and delivering capital projects that involve close collaboration among all stakeholders—owners, designers, constructors, operators, technology providers, and equipment suppliers—through all stages of a project. These methods include construction management at-risk (CMAR), progressive design-build (PDB), fixed-price design-build (FPDB), design-build-operate (DBO), and public-private partnerships (P3). Since its inception, WCDA has helped thousands of practitioners and project owners successfully adopt collaborative delivery solutions through its education, research, and advocacy. WCDA also partners with other industry organizations to further its mission. Thanks in part to those efforts, collaborative delivery is now the fastest-growing form of project delivery in the water and wastewater industry. Owners choose collaborative delivery because of its proven ability to drive better project outcomes with more innovation, control, certainty, and value.
