WATER SYSTEM REDUCES ENERGY COST BY INTEGRATION, AUTOMATION & INFRASTRUCTURE RE-ENGINEERING
Abstract Plumstead Township, PA achieved significant reductions in electric and maintenance costs by implementing a multi-project upgrade of their potable water system. Integrating several independent water systems within the Township, combined with re-engineering the system infrastructure and implementing supervisory control and data acquisition (SCADA) resulted in significant reductions in energy cost, labor and maintenance. The projects included: Constructing an elevated water storage … [Read more...] about WATER SYSTEM REDUCES ENERGY COST BY INTEGRATION, AUTOMATION & INFRASTRUCTURE RE-ENGINEERING
ENERGY AUDITING WATER AND WASTEWATER FACILITIES
Introduction Energy is one of the largest budget items for water and wastewater facilities. An energy audit, is an examination of a facility’s energy uses. Once energy use is identified the costs of the energy being used can be identified. Next, recommendations to reduce energy uses and costs, called Energy Conservation Measures (ECMs) can be identified. ECMs generally include equipment and operational changes. We will discuss: What is an Energy Audit? How is an Energy Audit … [Read more...] about ENERGY AUDITING WATER AND WASTEWATER FACILITIES
ENERGY AUDITS: BENEFITING YOUR DRINKING WATER AND WASTEWATER TREATMENT FACILITY
Energy accounts for about one third of the operating budget for drinking water and wastewater systems. It’s a facility’s largest controllable budget item so it’s a logical place to look for savings. The most important step in reducing energy costs is to have a good understanding of where the energy is being used in the facility. The first step is to conduct an energy audit to: evaluate possible operational adjustments and concepts; conserve energy and save money; and maintain or improve … [Read more...] about ENERGY AUDITS: BENEFITING YOUR DRINKING WATER AND WASTEWATER TREATMENT FACILITY
