Overview

For many municipal governments, drinking water and wastewater plants typically are the largest energy consumers, often accounting for 30 to 40 percent of total energy consumed. Overall, drinking water and wastewater systems account for approximately 2 percent of energy use in the United States, adding over 45 million tons of greenhouse gases annually.

As much as 40 percent of operating costs for drinking water systems can be for energy.

By incorporating energy efficiency practices into their water and wastewater plants, municipalities and utilities can save 15 to 30 percent, saving thousands of dollars with payback periods of only a few months to a few years.

EPA Webinars on Energy Efficiency for Water and Wastewater Utilities

Determining Energy Usage

As a utility manager, understanding how your water or wastewater utility uses energy and how your electricity provider structures rates will help you better manage both costs and your facility's operations. The first step is to determine your facility's baseline energy use. Another important step is to understand what impact energy-intensive processes such as pumping and aeration have for your facility and how you can prioritize improvements.

You can determine baseline energy use using third-party energy audits or self-assessments. Both water utility professionals and technical assistance providers can benefit from the resources provided below.

Cutting Energy Usage and Costs

Energy Management

Energy costs often make up 25 to 30 percent of a utility's total operation and maintenance (O&M) costs. They also represent the largest controllable cost of providing water and wastewater services. EPA works with utilities to manage and reduce costs, using the steps described in its Energy Management Guidebook for Wastewater and Water Utilities. The Guidebook takes utilities through a series of steps to analyze their current energy usage, use energy audits to identify ways to improve efficiency, and measure the effectiveness of energy projects.

EPA's regional offices are working with over 150 utilities to help develop energy management programs using the Guidebook and develop case studies of benefits seen by utilities.

Renewable Energy Options

Green power is electricity produced from renewable resources, such as solar, wind, geothermal, biomass, and low-impact hydroelectricity. Buying green power is one of the easiest and most effective ways to improve your organization's environmental performance.

On-site Energy Generation

In addition to consuming energy, wastewater utilities can generate energy. Combined heat and power (CHP), also known as cogeneration, is a reliable, cost-effective option for wastewater treatment facilities that have, or are planning to install, anaerobic digesters. Biogas from anaerobic digesters can be used in a CHP system as 'free' fuel to generate reliable electricity and power.

• Combined Heat and Power (CHP) Partnership - A voluntary program that works to reduce the environmental impact of power generation by promoting the use of CHP. The partnership works closely with energy users, the CHP industry, state and local governments, and other clean energy stakeholders to encourage the development of new projects and promote their environmental and economic benefits.
• EPA's CHP Partnership Report: Opportunities for and Benefits of Combined Heat and Power at Wastewater Treatment Facilities (PDF)(48 pp, 726 K, About PDF)

In addition to CHP, utilities can use various alternative energy sources to reduce their dependence on traditional energy sources. Options include solar panels (the most common), wind turbines, fuel cells, and micro turbines. Utilities can purchase and operate their own renewable energy generation equipment or contract with a third-party provider that owns and manages the green power on-site for them.

• The Customer's Guide to Solar Power Purchase AgreementsExit- This guide assists organizations that want to benefit from fixed-price energy through hosting solar power systems owned and operated by a third party.

Purchasing Green Energy

Instead of generating renewable energy on-site, some utilities opt to purchase renewable energy directly from the power grid or by purchasing renewable energy certificates (RECs). RECs are credits sold separately from electricity. They represent the environmental, social, and other positive attributes of power generated by renewable resources and enable organizations to choose renewable power even if their local utility or power marketer does not offer a green power product. Whether these options are available varies based on your facility's location and your electricity provider's offerings.

• Guide to Purchasing Green Power - The Green Power Partnership is a voluntary program through the EPA that supports organizations by offering expert advice, technical support, tools, and resources to buy green power and reduce the environmental impacts associated with purchased electricity use. Partnering with EPA can help your organization lower the transaction costs of buying green power, reduce its carbon footprint, and communicate its leadership to key stakeholders.

Funding Green Power

• U.S. Department of Agriculture, Rural Development, Rural Energy for America Program (REAP) Guaranteed Loan Program - This program encourages the commercial financing of renewable energy (e.g., bioenergy, geothermal, hydrogen, solar, wind, and hydroelectric power) and energy efficiency projects. Under the program, project developers work with local lenders, who in turn can apply to U.S. Department of Agriculture Rural Development for a loan guarantee of up to 85 percent of the loan amount.
• Database of State Incentives for Renewables and Efficiency (DSIRE)Exit - This database contains information on state, local, utility, and federal incentives and policies that promote the adoption of solar technologies. Funded by the U.S. Department of Energy's Solar Energy Technology Program, DSIRE SOLAR is a new component of the DSIRE project that provides solar-specific policy information to consumers, policy makers, program administrators, the solar industry, and other concerned parties.

State and Local Efforts to Promote Green Energy

State and local governments are developing programs to help public water systems and wastewater treatment facilities use renewable energy.
