The concept of an integrated Energy and Water Quality Management
System (EWQMS) was introduced in the early ‘90s to
provide water utilities with the foundation for a systems control
management tool for simultaneously achieving energy efficiency
and water quality objectives [Jentgen et al., 2003]. An EWQMS is a
collection of individual application software programs,
useredeveloped or commercially available, that allow the implementation
of an array of energy cost reduction strategies operating
within designated constraints. Real‒time communications with
preeexisting SCADA (Supervisory Control and Data Acquisition)
systems allow the EWQMS software to monitor and proactively
provide recommendations regarding system operation (e.g.,
pumping, storage tank turnover, etc.) based on timeeofeday electrical
use and associated tariff, forecasted demand and pump
scheduling [Barnett et al., 2004].
