Findings from a Capital Expenditure Analysis Timing Evaluation Performed for the Fairfax County NCPCP

摘要

A capital investment financial analysis tool was developed to evaluate the impact of implementing different primary, secondary, and tertiary treatment capital investments and phasing under different future condition scenarios. This financial analysis tool takes a holistic, whole plant (liquids) approach to evaluate and quantify the anticipated costs of improvement scenarios based on anticipated increases in nutrient loading. This analysis was used to determine the optimal timing and type of infrastructure investments related to the NCPCP primary/secondary and related tertiary processes.
