Prepared by the Task Committee on the Sustainable Design of Pipelines of the Pipeline Location and Installation Committee of the Pipeline Division of the Utility Engineering and Surveying Institute of ASCESustainable Design of Pipelines: Guidelines for Achieving Advanced Functionality, MOP 151, provides a conceptual tool and a decision process that can be used to evaluate the potential impacts of a project and promote improvement in sustainable planning, design, construction, and operation to create a project that goes beyond the typical standards of care for pipelines used by the water, wastewater, and storm water industry. This Manual of Practice demonstrates how to develop sustainable solutions through a well-defined process that includes Transparent and inclusive sustainability assessment methodology, Clear problem definition, Clear and measurable criteria to assess sustainability (Triple Bottom Line) as defined in the Envision Guidance Manual, Full suite of alternatives for assessment, and Consideration of collateral impacts. This MOP is designed for engineers, planners, owners, and public officials to utilize within the pipeline industry.
