The Successful Design, Construction and Commissioning of A 11 L/S (0.25-MGD) Biological Nutrient Removal PILOT Plant in Ten Months

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:Adherence to an extremely tight scheduleManaged risk to the DistrictAppropriate equipment and materials selectionSeamless testing, startup and commissioning
