Featured Videos: Solids and Sludge Handling

How are solids handled and sludge thickened in the wastewater process? Watch this RCAP video to find out how one wastewater plant uses a dissolved air flotation thickener to settle sludge out before the digestion process and then uses a centrifuges for de-watering.  

Need to simplify the process? Check out how this small wastewater plant in Ohio reduces the free water content of its sludge - all for under $300 out of pocket cost. 

Looking for more videos on the wastewater treatment process? RCAP offers a free 7-part video series to explain the technical steps in the process of treating wastewater. 

Energy Efficiency in Action

Small systems across the country are challenged to raise revenue in order to pay for the infrastructure and water treatment upgrades necessary to meet stricter water quality regulations. However, what if this revenue shortcoming could be made-up over time within a utility itself, sometimes without raising rates? Implementing an energy audit and then applying cost-efficient energy-saving strategies may be just the ticket.

An audit or self-assessment can help staff understand how their utility uses energy as well as the impact energy-intensive processes such as pumping and aeration has on overall usage. The EPA offers a range of tools available to help with this process, including an energy use assessment spreadsheet tool.

Once an audit is complete, utilities can develop a program to reduce energy costs. RCAP suggests focusing on these five areas: benchmarking, lighting systems, HVAC systems, pump efficiency, and wastewater treatment. According to Ohio RCAP potential energy-cost reductions can range from 6 to 62 percent, with an average of less than a 1-year simple payback for communities that are actively using energy audits and energy-reduction programs.

It is always inspiring to learn about energy-saving strategies used by other systems. The wastewater plant in Copperas Cove, Texas, for example, installed new energy-efficient blowers, a modern aeration control scheme, finer screening at the headworks and a maintenance-friendly air diffusion system in order to cut their energy costs. Since their improvements, total average monthly energy costs at the plant have dropped by nearly 25%—from $22,000 per month to $16,000.

And this video shows how a utility in Evansville, IN was able to upgrade its wastewater plant without raising rates. In addition, the city became the first in the country to generate clean energy using FOG, or fats, oils and grease.

A good way to brush up on how to operate efficient small utilities is by reviewing RCAPs planning and resource guide or the EPA's Strategies for Saving Energy at Public Water Systems or Florida Rural Water's Energy Reduction Techniques for Small and Medium Systems. In addition, this handbook from South Dakota DENR guides small systems step-by-step through the auditing process and explains how to develop an energy conservation program, identify and implement energy conservation measures (ECMs), and monitor the progress and success of the implementation program.

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. 

Focus on Apprenticeship Programs

It is no secret that drinking water and wastewater utilities are facing a shortage of workers due to job growth and the retirement of the baby boomer generation. Nationwide, over 30-50% of the water workforce is expected to leave the industry in the next decade due to just retirements alone. However, some states, and especially those with a large percentage of smaller, rural systems such as Idaho, face even more serious shortages.

To make matters worse, it isn't always easy for new folks to get a foot in the door. High school graduates may not be aware of the water industry jobs available in their own communities, and even if they become aware, it can take a significant investment of on-the-job experience and education to obtain the proper knowledge and licensure to become an operater.

This is why many state & local governments, community colleges, utilities and water organizations have been collaborating to develop apprenticeship training programs across the country. For example, Indiana Alliance of Rural Water runs an apprentice program as part of a larger NRWA water sector apprenticeship initiative. Their apprentices train alongside experienced technicians while earning a entry-level wage, all in the interest of creating a more robust workforce for the state.

Another water organization, the Water Environment Association, has recently been collaborating with the City of Baltimore to train young people for the water industry. The Baltimore City Water Industry Career Mentoring Program, now in its third year, is an eight-month program for 18-24 year olds that provides water industry career exploration, worksite tours and job shadowing, connections with a career coach/mentor, a summer job at Department of Public Works, and opportunities to interview for full-time, entry-level positions.

Other recent initiatives attempt to recruit workers even before they graduate from high school. A youth apprenticeship program sponsored in part by New Water in Green Bay, WI, offers students the opportunity to gain valuable work experience and insights into the wastewater industry while still attending high school. NEW Water collaborates with the Greater Green Bay Chamber, Northwest Technical College and area school districts for this program.

More and more municipalities are also responding to the need to plan for their futures via apprenticeship programs. The city of Prestonsburg, KY, for example, has recently announced the creation of a 3-year apprenticeship program. Their program partners with a local community college to reduce the time it takes to become a certified water or wastewater treatment operator, giving the city a competitive edge in the race to replace their retiring operators.

Finally, the rise in the need for, and popularity of, apprenticeship programs underscores the importance of continuous monitoring to ensure that apprenticeship outcomes are measuring up to expectations. According to the LA Times, an audit of the apprentice program for Los Angeles' Department of Water and Power revealed that only 51% of those enrolled actually graduated, and those with the highest level of training were being recruited elsewhere.

Featured Video: The Science Behind Exploding Manhole Covers

Every season has its challenges for public works departments, and now that spring is just around the corner, it is pretty obvious that this past winter came with more than its fair share. Yet we are not in the clear quite yet, as this news story about two manhole explosions just a few weeks ago demonstrates. In fact, as winter winds down, accumulated road salt compounds corrode through underground electrical cables, causing sparks to ignite gases that can build up in confined spaces. With over 2,000 annual incidents in New York City alone, exploding manholes are not a joke: they can be dangerous, destructive and downright difficult to predict.

And while large cities like New York City are especially prone to these incidents due to aging infrastructure and the sheer amount of underground electrical cables present, small towns are definitely not immune. For example, in 2014 the tiny town of Sauget, Illinois (pop. 150) experienced an explosion so powerful manhold covers damaged overhead power lines.  

 Find out more about how road salt compounds contribute to this problem in this week's featured video.  

While explosions are the most dramatic hazard associated with manholes, research suggests that manholes are in general one of the most dangerous work locations for water system staff. In fact, according to AFSCME, fully one-third of all injuries/deaths of workers occur in or around manholes. Check out this safety presentation hosted by Michigan WEA for more information on the types of hazards presented by manholes and how to protect yourself from them. 

And if you have any lingering doubts about the force, and destructive power, of an expoding manhole, take a look at this video. 

Featured Video: Buried History - Wooden Water Mains

There's quite a lot of talk these days about aging underground infrastructure, but I bet nobody is referring to archaeological finds! Long-abandoned wooden pipes left beneath older communities aren’t unheard of, but outdated utility plans typically don’t pinpoint their location and it is rare to dig one up, according to this Washington Post article. This week's featured video shows how the New York City Department of Design and Construction worked with Chrysalis Archaeology to preserve their 200-year old wooden water main "find", a portion of the first piped water system in the city. 

Wooden water mains have been found in rural areas and large and small towns across the country, from Baltimore to Philadelphia to Gladstone, Michigan and all the way to the West Coast as well. Some of these wooden pipes serviced customers for 100 years or more! Interested in finding out more? Check out this article about the era of wooden water pipes in Portland, Oregon. 

The Importance of Customer Outreach

Featured Video: An Inflow and Infiltration Reduction Program in Missouri

Inflow and infiltration (I/I) can be very costly for small communities, especially those communities with outdated combined wastewater/stormwater systems or collection systems in poor repair. According to this classic National Small Flows Clearinghouse article, I/I problems place additional burdens on these older and/or fragile systems because the extra water that seeps or flows into them can be very damaging, and, in some cases, even cause contamination issues.

This week's featured video describes how the City of Columbia, Missouri is attempting to locate, identify, and correct improper connections and defects that cause these inflow and infiltration problems so that their system capacity improves, and sanitary sewer overflows and basement backups are eliminated.
