The Advanced Treatment Technology Pilot (ATTP) project provides a valuable example for successfully implementing a fast-paced project to demonstrate compliance with stringent nutrient removal and tertiary treatment permit requirements. The ATTP project was designed, built and commissioned in ten months on schedule, on budget, with no injuries, and at a construction cost of $12 million. This paper contains a description of how the selection of a design, build, own, and operate (DBOO) delivery implementation benefitted the project. Lessons learned regarding pilot startup and operations and maintenance of the analytical instrumentation are also included. The DBOO implementation allowed and fostered a successful ATTP project which achieved: 1. Adherence to an extremely tight schedule 2. Managed risk to the District 3. Appropriate equipment and materials selection 4. Seamless testing, startup and commissioning
