Full Description

This powerpoint presentation begins by providing a brief overview of treatment plants and water storage in the Norfolk/Virginia Beach area of Virginia. Study objectives included: maximize pumping efficiency by optimizing pumping schedule during high demand hours, including reducing pump start frequency to reduce O and,reducing residence time in the storage tanks toimprove overall water quality. Study approach included the following: Extended Period Simulation (EPS) Hydraulic ModelDevelopment;Demand Patterns Development;Evaluation of System-wide Storage Capacity;Development of Optimized Operational Schedule; and,Verifications of Optimized Operating Schedule. Includes tables, figures.
