What do the icons below mean? Pumping system efficiencies are decreased if: The pump is operating outside of its pump curve efficiency range. The pump is worn or not of a proper design. The flow of water is restricted or throttled on the suction (and/or) discharge side. The electrical control system, i.e., VFD is not…

What do the icons below mean? Upgrade key chlorinating disinfection units to more efficient systems, utilizing less energy either in production and/or transportation and handling of product. Investigate chlorine generation systems. We live in a State with accessible and cheap salt deliveries, making the electrolytic generation of chlorine much more efficient. Implement more natural and…

While the list below appears extensive, it is still not inclusive of everything, as such, do not become overwhelmed. The rewards of this exercise will likely be small in some areas, but can be great in others. Remember that summed together, they can show significant economies in operational performance and costs. Go about this effort…

This section describes energy efficiency strategies that can simply be achieved by management or operation changes in the way we function in the workplace. Many of these strategies require very little money or effort to achieve a savings. Sustainability Review State and EPA Standards for capacity development in the following areas and implement the standards:…

What do the icons below mean? Ensure that all new water storage and pumping facilities are designed and sized with off-peak pumping demands in mind. Study potential ASR programs (Aquifer Storage and Recovery), including possibly other similar groundwater programs to reduce the peak pumping and treatment load on the company facilities in the summer months.…

What do the icons below mean? Much of the data-gathering and fieldwork necessitated by this section should be performed by qualified personnel, who are adept at electrical safety and arc-flash procedures: Carefully select the appropriate utility energy rate for the pumping application (See Energy and Power Rate Dynamics). Pumping Selections should be based on unit…

What do the icons below mean? Ensure that all PRVs are properly maintained and tuned to provide optimum pressure levels which may, in turn, reduce accompanying distribution system water losses. Review fire hydrants annually and test for possible leaks. Keep a centrally accessible and well-maintained set of pipe location and leak detection instruments to ensure…

Energy conservation almost always begins with water conservation, including the process of improved accounting for water losses within the various complex operational systems. Water Conservation Encouraging water conservation has a direct linkage with energy conservation. Not only does it save energy resources, it also frees up water that can be used for future uses, reducing…

Using icons, items in this Energy Cost Savings Report are classified into three energy auditing tiers alongside a corresponding project, or group of projects, indicating the possible resources needed to accomplish the tasks.

The content for the Drinking Water Energy (Cost) Savings Program Web pages and associated Handbook was prepared by many people and it is appropriate that they be given credit for their work. I will proceed in giving credit consistent with the order in which the Handbook is organized. I acknowledge the work done by Steven…

A/C: Air Conditioning AC: Alternating Current ac-ft: Acre Feet; a volume of water covering an acre a foot deep (43,560 cubic feet). air-vac: Air Vacuum Valves ASR: Aquifer Storage and Recovery AWWA: American Water Works Association C: The discharge coefficient used in the Hazen Williams equation of flow (the higher the C value the higher…

This handbook was prepared to provide water system operators and managers with ideas on how to save a significant amount of money by reducing the cost of power necessary to provide water to their customers. As a minimum, the ideas presented herein should enable water systems to lower the cost for power in spite of…
