it is important to realize that the conditions that existed at initial
start-up will change over time due to various passive and active
influences ( Table 1) resulting in reduced energy efficiency.
The #4308 guidebook helps water utilities be more aware of
and better manage these influences. It also presents eight case
studies to illustrate energy savings concepts:
º Energy optimization using power monitoring
º Conventional vs. thermodynamic methods of pump perfor-
º Pump sandblasting and coating
º Modification of pump station operation
º Installation of VFDs at booster pump stations
It is important that pump stations, which are major contribu-
tors to energy usage in drinking water systems, are designed
and operated in a cost-effective and energy-efficient manner.
WRF Project #4308, Drinking Water Pump Station Design and
Operation for Energy Efficiency (Senon et al. 2015), was developed
as a guidebook for understanding the performance of the major
components of a pumping system. The guidebook summarizes
major design parameters and principles of various pumping sys-
tem elements that may have an impact on energy consumption.
Conceptual examples are used to illustrate the principles.
Properly operated and maintained pumps can provide years of
efficient and reliable service. Once a pumping system has been
fully commissioned and placed into normal operation, however,
in the Water Sector
Water utilities are increasingly focused on energy-efficient and environmentally sustainable solutions because of rising energy costs, energy security and reli- ability concerns, and greenhouse gas (GHG) emissions from energy usage.
