Spooky Sewers and Things That Go Bump at the Treatment Plant: 2018 Edition

Featured Video: Using Powdered Activated Carbon to Remove Cyanotoxins

In May of this year, the city of Salem, Oregon discovered the state's first-ever algae breach in finished drinking water. Since then, there has been quite a bit of soul-searching, as well as a third-party assessment of exactly what happened and the effectiveness of the water utility's response after the event. In the end, the assessment concluded that the city was not prepared to deal with the public relations fallout, or the more practical matter of helping citizens access emergency water supplies. 

In the meantime, the Oregon Health Authority responded by creating almost unprecedented new cyanotoxin monitoring regulations for systems across the state, and the city of Salem was left to figure out how to cope with what may turn out to be a long-standing threat.

As an emergency measure, the utility started using powdered activated carbon (see video below from Statesman Journal reporter Dick Hughes) but it can cause clogging of the filtration plant.  The city is now also looking into ozone filtration, as well as other improvements including hazard response and crisis communication planning in order to be better prepared to handle future events.

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.

Featured Video: What Does it Take to be an Operator?

Water and wastewater operators provide critical services to their communities, and yet the work they do often flies under the public's radar. This lack of visibility can make it challenging to attract new talent to the field. At the same time, a shortage of certified operators is expected as older operators retire.

This workforce shortage can hit rural areas and small systems particularly hard, as they often can't keep up with pay rates offered by larger, urban systems. Recruitment strategies include apprenticeship programs, partnerships with community organizations, programs for veterans, and more, but it certainly wouldn't hurt to attract the right kind of people to the field in the first place.

This video includes interviews with two operators who talk about how they got into the field and what skills they use in their jobs. This video can be shown to encourage people to enter the field, including high school, college and community college or trade school students.

Methane Safety at Wastewater Plants

Last week, a large explosion at a water reclamation facility in Calumet, IL served as a somber reminder of the importance of following safe practices when dealing with methane gas or any flammable material at treatment plants. While no one was killed, there were injuries and some of these were severe.

With this in mind, there is no better time than now to review safety procedures and training practices for working around potentially explosive materials like methane.

An important first safety step, according to this Spring 2018 article in Missouri WEA's Current Magazine, is to check your facility for gas leaks and accumulations. When doing this, it is better to use a combustible gas meter than to rely on your sense of smell, because an individual's nose can become desensitized to the tell-tale rotten-egg smell over time. In addition, it is essential that workers know how to use monitors properly, and test them regularly.

Other recommendations include the installation of an automatic fan/ventilation system and a permanent gas detection system.

Finally, as this safety presentation from Suez points out, never perform hot work unless explosion risks have been identified and eliminated. If you need a visual reminder about why this is so important, this video from the US Chemical Society & Hazard Investigation Board (USCSB) lays out the events leading up to a fatal Florida wastewater plant explosion in 2006.

Gas and chemical hazards are an invisible but unavoidable fact in the operations of a wastewater treatment plant. Get a step ahead of the game by reviewing these tips and following the correct protocol - it's the best way to ensure that you return home safely each workday.

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.
