Whether we live in houses or apartments, we all probably share the same sense of hesitation when we open our monthly electric bill…especially after some frigid winter months.
Keeping the environment and our household budgets in mind, it makes sense to consider ways to reduce these bills with more efficient appliances, and conservation measures to use less energy whenever possible.
Just like homeowners and renters, most operators of large water and wastewater treatment plants are always looking for ways of lowering energy consumption and the costs that come with it, and reducing their greenhouse gas emissions in the process. The difference is that their power requirements are enormous.
Did you know that nationally, electricity accounts for 25 to 40 percent of the operating budgets for wastewater utilities and approximately 80 percent of drinking water processing and distribution costs? In fact, drinking water and wastewater systems account for nearly four percent of all the energy use in the United States.
EPA’s Net Zero Energy team is helping utilities to lower their costs by reducing waste, conserving water, and lowering power demand.
I recently attended a meeting at the Metropolitan Washington Council of Governments, the regional planning group for in the District of Columbia, suburban Maryland and Northern Virginia where energy conservation and reductions were the chief topics. Each authority had used experts in the field to assist them in examining energy saving actions, and estimating the costs of implementing them.
While many of these energy projects involved little or no cost, others carried a more significant price tag. Each authority selected what actions would get them the biggest “bang for the buck” within their capital improvement budgets, and would pay for themselves within one to 10 years in energy savings.
While many large water and wastewater authorities are already benefiting from these energy saving measures, some of the smaller ones are just starting to learn about them. A couple of EPA publications entitled “Energy Efficiency in Water and Wastewater Facilities” and “Planning for Sustainability: A Handbook for Water and Wastewater Utilities” can provide the necessary first steps for a community or authority to begin such an effort.
Why not encourage your local utility to check out the savings?
