Energy Efficiency Resources for Small Utilities

On a typical day at the plant, water and wastewater system personnel are challenged to do a lot with a little in the service of protecting and producing water for their community. Certainly one way staff members are demonstrating this resourcefulness has been in their adoption of energy efficient strategies and programs. 

Why is this important? Simply stated, saving energy can help small systems put their scarce resources towards what really matters: safe drinking water and clean wastewater discharge.  

According to Wisconsin's Focus on Energy Best Practices Guide for the Water and Wastewater Industry, additional benefits to water systems include improved control and treatment as well as shorter paybacks compared to other industries on capital costs for energy efficiency improvements. Of course, the amount of energy savings will vary depending on the type of system in use, the age and condition of the equipment/infrastructure and the capital available to implement major changes, if necessary. 

But even if you have little to no capital available to make improvements, energy savings are still very much possible! This resource from the U.S. Department of Energy, and this list from ORACWA, for example, list the many low or no-cost measures plants can take to save energy, and therefore, money. 

But before you start an energy savings programs, the EPA recommends that you conduct an energy audit or assessment of your system. Free tools for doing this can be found on the EPA's Energy Efficiency for Small Drinking Water Systems webpage, or you can view this webinar recording. In addition, the Rural Community Assistance Project (RCAP) staff across the United States may be able to carry out energy audits for drinking water and wastewater facilities. Find the contact information for your RCAP region at https://rcap.org/contact/.

The next step is to identify the easy targets. RCAP has an article (Five Things You Can Do To Save On Energy in Your Utility) and a video to help you do this. In addition, the EPA has a step-by-step presentation on energy self-sufficiency and the role new technologies can play to help you achieve this. 

Other resources include: 

• Florida Rural Water Association's Energy Reduction Techniques for Small and Medium Water and Wastewater Systems
• EcoWork's Energy Efficiency Strategies for Water and Wastewater Systems
• USEPA's Ensuring a Sustainable Future: An Energy Management Guidebook for Wastewater and Water Utilities
• SEPAC's Energy Smart Tips: Water Treatment Plants 
• TNDEC's recent Case Study of Carthage, TN (pop. 2300)

Finally, here are some energy facts that might just surprise you! 

• Over 90 percent of energy consumed in producing and delivering drinking water is used for pumping. 
• 30 to 60 percent of a municipality’s energy budget is spent on the treatment of water and wastewater.
• According to the U.S. Dept. of Energy, energy audits typically identify potential savings to the user of 10 to 40 percent, with 20 percent being the average.

Hiring an Engineer for Your Infrastructure Project

Water and wastewater systems can be some of a community's largest investments, so it is really important to get it right—decisions made in the early stages of infrastructure planning can impact a community for generations to come.

Community leaders are often tempted to let an outside consultant completely handle the project because they are worried they don't have the expertise to make the right decisions. However, it is important to stay actively involved so that the community’s voice is not lost and the project is appropriate, affordable, and supported by the public.

Certainly one of the most critical early-stage decisions in this process is who to hire as your engineer, the person who will be involved in nearly every aspect of the project from evaluating financing options, completing designs, obtaining permits, bidding the project, and the actual construction. And make no mistake, this hiring process can be a challenging task. Luckily, WaterOperator.org has a collection of resources to help you through.

For example, this RCAP guide explains the steps that communities can take to gain control of the project-development process. It is a very detailed how-to and includes many pitfalls to avoid. It discusses securing funding, how to stay organized, and, how to hire an engineer. RCAP recommends following a QBS (qualification-based selection) process in order to choose an engineer whose strengths, experience and skills match your system's needs. 

For more information regarding the QBS process, you can read this manual from Ohio Qualification Based Selection Coalition (while some of the information may be specific to Ohio, much of the process is similar regardless of the state). In addition, RCAP has a handy list of 10 tips to help communities hire an engineer.

Other helpful resources in our library include Washington State DOH's guide for small public water systems on how to hire an engineer. Included in this guide are considerations regarding how to determine costs of services provided. Idaho's DEQ also has an engineer hiring guide that includes questions to ask during the interview. And this MAP guide emphasizes the importance of having a survey or analysis of the condition of your present system, as well as the problems a new project will address. This "Scope of Work", according to MAP, is perhaps the most important part of your Request for Proposals when searching for an engineer.

A final, but valuable, piece of advice, repeated throughout these resources, is that selection should be based on demonstrated competence and qualifications and not on price for services rendered. In this way, you can ensure that the project will be a valued community asset for years to come.

Free Resources for Non-Community Water Systems - Recording on June 6, 2018

This webinar, recorded on June 6, 2018, introduces our free, 2-hour online course that helps owners and operators of public water systems with a groundwater well better understand how to properly care for their water supply. The course curriculum includes the basic science of groundwater, well mechanics, and source water protection best practices. 

EPA Releases Preventive Maintenance Tools for Small Systems

The first tool to be released is an updated version of EPA's popular Preventive Maintenance Card File tool. This 857-page easy-to-access electronic version can be tailored to a system's needs. It includes fillable pdf logs for each month as well as logs for common daily, weekly and monthly tasks. In addition, it can provide detailed information about maintenance and operation, source water, emergencies, security, treatment processes, monitoring/sampling, storage, distribution, rules/regulations, operator certification, customer complaints, technology, supplies, important people and more.

The tool can be downloaded in its entirety as a zip file, or you can download individual months/files. If your system prefers a printed format, the logs can be printed out or you can opt to print out the original 2004 Preventive Maintenance Card File for Small Public Water Systems here.

Focus on Chlorine Safety

Chlorine is one of the most widely used industrial chemicals in the world today, with 13 million tons produced annually in the United States alone. And although there are alternative treatment methods, the majority of water systems still use some form of chlorine for disinfection because it offers an affordable and well understood means of eliminating waterborne diseases. In fact, filtration of drinking water plus the use of chlorine has been called one of the most significant public health advancements of the 20th century.

Yet every treatment technology has its risks, and it is critical to understand the dangers. That is why your employee safety training programs are so important. Here are some supplemental chlorine safety resources from our document library to help support an active chlorine safety/emergency response program at your plant. 

• Water and Wastewater Operators Chlorine Handbook from the Chlorine Institute
• How to Handle Chlorine Gas Safely from Washington State Department of Health

Repairing a Live Water Main

Get out your waders, ladders, clamps and sleeves! There’s nothing quite like the excitement of repairing a water main under pressure – and nothing quite like the kind of water operator who willingly climbs into a deep hole filled with water and mud in all types of weather.

According to Colorado Springs Utilities, there is no shortage of these opportunities: more than 240,000 water main breaks occur each year in the United States, and each one has its unique challenges. But for many of these breaks, you don't need to turn off the water.

Why? Well it goes without saying that repair work should be performed, if at all possible, without interrupting service to customers. Moreover, maintaining positive pressure in the line helps the utility avoid water quality concerns, further service failures caused by valve closures and the need for additional monitoring/sampling. 

Finally, doing live repairs means the utility does not have to issue a boil order notice, which can affect customer confidence and add additional incident reporting/paperwork requirements.  

So, when done safely and correctly, live water main repairs not only make sense for everyone, but also provide a bit of excitement in the work week! 

Need a step-by-step breakdown on the process? Check out this video from the Village of Downers Grove, IL: How to Repair A Water Main Break in 8 Easy Steps

And, for your viewing pleasure, here are a selection of YouTube videos of recent live water main repairs: 

• This video provides guidance for strategic foot placement during a live water main repair.
•  And this video offer proof of how quickly the repair can be made!
• And this video shows an example of a water main break you will hope to never see in person!

Drought Resources for a Dry Summer

If you live in Alabama, Georgia, South Carolina or parts of the Southwest, your utility may be facing drought conditions this summer. Recently, we’ve shared resources for setting rates to encourage water conservation, gaining community buy-in through social marketing, and helping customers track their water use through smart metering.

Yet if you’re not sure yet what your utility needs, you can find a start-to-finish planning guide in the EPA’s comprehensive Drought Response and Recovery Guide, which provides worksheets, best practices, videos and key resources for responding to drought. The guide is paired with an interactive map of case studies of small and medium-sized drinking water utilities in the U.S. that have successfully responded to drought. Video interviews of utility managers and officials will walk viewers through how these towns located emergency resources and then built up their long term resilience.

Rural development specialist Dean Downey of RCAC recommends four steps below to developing a water shortage contingency plan.

Step 1: Establish your utility priorities. The EPA and USDA's Rural and Small Systems Guidebook to Sustainable Utility Management lists ten key management areas of sustainably managed utilities.  By addressing priority areas such as product quality, financial viability, operation resiliency, and others, water system managers can address challenges and increase their effectiveness.

Step 2: Identify your potential water shortage events. Drought, water quality degradation, or equipment failure can reduce or eliminate supply. Water treatment or distribution system failure can also cause major water shortage events. Events can be natural, man-made, or due to equipment failure. As utility system personnel you will most likely have the best idea where to focus your limited resources in planning for water shortages.

Step 3: Assess risks. Don’t spend your time on events that probably won’t occur or that will have limited impact on your utility. Assess both the likelihood and impact of a failure to evaluate the risks.

Step 4: Involve other stakeholders. Don’t forget to include other agencies and groups in the process. Utility personnel are prone to believe they can handle just about any incident. This may be true to a certain extent, but usually utilities underestimate available resources and abilities needed to handle larger or more complex water shortage events.

Downey writes that additional steps include, examining water supply and demand, identifying trigger mechanisms for implementing the plan, and ensuring financial and legal backing.

You can view a full list of RCAC materials for drought planning here, including the Action Plan for Emergency Drought Management, a template for water systems serving fewer than 3,300 people to help assess a drought situation and take immediate actions to mitigate its impact on the community.
