PWPEx Tool v1.0 of Plant Water Profiler Tool in Excel format. It was developed at Oak Ridge National Laboratory (ORNL). PWPEx Tool is a comprehensive tool designed for use by manufacturing plants falling under NAICS (North American Industry Classification System) Codes 31, 32, and 33 to help their sustainability teams:
- Understand the procurement, use, and disposal of water in their plants;
- Be cognizant about the “true cost” of water, including the costs associated with water procurement, treatment, and consumption and wastewater disposal; and
- Identify opportunities for reducing water use and achieve associated cost savings.
Features and Capabilities:
Water-consuming systems in industrial manufacturing plants include processes, cooling and condensing systems for process, power generation, and air conditioning, steam boilers for power generation and facility needs, kitchen and restrooms, and landscaping and irrigation, and fire sprinkler systems. PWPEx Tool helps break down the total plant water intake, wastewater disposal, and “true cost “of water by individual systems in the plant. Thus, it helps management identify systems that contribute the most toward source water intake versus “true cost” and enables efforts to prioritize water efficiency measures. Results can also be used to establish a baseline and track water use during subsequent years.
PWPEx Tool evaluates “water balance” by individual systems, accounting for the source water intake, recirculated water, consumptive water use, and wastewater disposal. This helps management estimate water losses as well as potential water and “true cost” savings that can be achieved from increasing water recirculation and eliminating water losses.
PWPEx Tool assesses the water efficiency status of a plant and its individual systems and provides a tailored list of water efficiency measures and opportunities specific to the plant. Thus, PWP Tool is a “first step” that industrial manufacturing plants can follow to minimize their water use and achieve cost savings.
Acknowledgments:
PWPEx Tool was conceived and developed by researchers at ORNL with funding from the US Department of Energy’s Advanced Manufacturing Office. Several technical experts from the US manufacturing industry contributed to the tool’s development by evaluating initial versions.
