A Case for Regionalization

Water and wastewater services are needed in every community in order to sustain it, but some communities need more assistance in order for their water utility to thrive. Many rural areas face challenges like meeting strict regulations while still providing affordable services to users. As technology becomes more sophisticated, the need to purchase new, expensive equipment becomes unavoidable for small utilities that often do not have the funding or resources needed. This is when regionalization can really benefit utilities and their customers alike.

Regionalization helps two or more water systems to leverage and combine resources, equipment, personnel, and even physical plants. According to U.S. EPA, “the main benefit of regionalization is that it pools individual resources of two or more water systems to obtain services or facilities that one or both systems may not have been capable of obtaining by themselves.”

In the Rural Community Assistance Partnership's (RCAP's) 2021 report: Affordability and Capability Issues of Small Water and Wastewaters Systems: A Case for Regionalization of Small Systems, they feature a case study that shows a successful model for regionalization from the Greater Cincinnati Water Works (GCWW) in southwest Ohio. GCWW offers the smaller water systems in the area much assistance in the form of: lab testing services, billing services, call center operation, a source of project financing, construction management services, engineering services, and emergency help when needed. 

RCAP also released a report titled: Regionalization: RCAP’s Recommendations for Water and Wastewater Policy which contained 22 recommendations that should be integrated into policy decision-making. The research featured in this report was unveiled in a webinar that also focused on the experiences of five different states: California, Florida, Ohio, Pennsylvania, and Texas, who spoke about what they have put in place to help support the various forms of regionalization.

The State of California Drinking Water

California has long been an epicenter of water issues, but the current megadrought and chronic infrastructure underfunding has brought the crisis to a head. According to a recently published study, California's water systems are beginning to fail across the state. Medium and small-sized public water systems are especially vulnerable.

The report claims to be the first comprehensive analysis of how safe water is provided in California. The study sampled 2,779 public water systems and nearly half proved to be at some risk of failing to provide safe drinking water. Roughly one-third of state small water systems sampled in the study were found to potentially contain contaminants like nitrate and arsenic. 

The greatest takeaway from the findings was that more funding is needed and that investments should prioritize the most at-risk and underserved communities. However, in the short term, bottled water or home filtration systems could be provided to communities that need drinking water immediately, according to the report. Long-term solutions to these problems include enhancing water treatment, consolidating small and underperforming water systems, and recruiting experts that can advise communities on how to improve their systems.

RCAP Advocacy and Policy Update: COVID-19 Response

Over the last two weeks, the National Office has been active in promoting the needs of rural water systems and small communities during this ongoing COVID-19 crisis. In the last two weeks, Congress has approved and President Trump signed into law Phase 1 (H.R. 6074) and Phase 2 (H.R. 6201) legislation addressing the COVID-19 crisis in a variety of ways. Phases I, II, and III are the three parts to COVID-19 legislation so far. 
 
Phase I, enacted into law March 6. Provides $8.3 billion in emergency funding for federal agencies to ensure vaccines developed to fight the coronavirus are affordable, that impacted small businesses can qualify for Small Business Administration (SBA) Economic Injury Disaster Loans (EIDLs), and that Medicare recipients can consult with their providers by telephone or teleconference, if necessary or desired.
 
Phase II, signed into law on March 18. This package includes provisions for paid sick leave, free coronavirus testing, expanded food assistance, additional unemployment benefits, and requirements that employers provide additional protection for healthcare workers. 
 
Phase III, signed into law on March 27. The Trump administration struck a deal with Senate Democrats and Republicans on a package providing an estimated $2 trillion in spending and tax breaks to strengthen the U.S. economy and fund a nationwide effort to curtail the coronavirus. The price tag of this package is enormous, unprecedented, and is roughly equal to 10% of the country’s economic output. The plan includes approximately $500 billion that can be used to back loans to distressed companies, including $50 billion for loans to U.S. airlines, as well as state and local governments. It also contains more than $350 billion to aid small businesses. While stipulating the airlines as eligible for a special fund of money available for loans, the legislation is otherwise broad in its approach, recognizing that the coronavirus has affected almost every sector of the economy. 
 
It provides payment to states to reimburse nonprofits, government agencies, and Indian tribes for half of the costs they incur through December 31, 2020 to pay unemployment benefits; and funding to support “short-time compensation” programs, where employers reduce employee hours instead of laying off workers. Employees with reduced hours receive a pro-rated unemployment benefit. This provision would pay 100 percent of the costs they incur in providing this short-time compensation through December 31, 2020.
 
Under Phase Ill, all U.S. residents with adjusted gross income up to $75,000 ($150,000 for married couples) would get a $1,200 ($2,400 for couples) "rebate" payment. They are also eligible for an additional $500 per child. The payments would start phasing out for earners above those income thresholds and would not go to single filers earning more than $99,000; head-of-household filers with one child, more than $146,500; and more than $198,000 for joint filers with no children.

Thank you to Ted Stiger, Senior Director of Government Relations and Policy at the Rural Community Assistance Partnership for providing this update on enacted legislation related to the pandemic.

Featured Video: Wastewater Treatment Process Control Testing

This week’s featured video was produced by the Athens Wastewater Treatment Plant. The plant serves a small town of approximately 1,050 people in West Virginia. In an effort to educate their small town and others across the country, Athens WWTP has developed a series of videos. In this particular recording, the plant will demonstrate several process control tests they use to evaluate their wastewater conditions. You’ll learn how Athens performs a settleometer test and monitors pH, temperature, dissolved oxygen, oxygen reduction potential, mixed liquor suspended solids, and volatile suspended solids.

Tests likes these are valuable for troubleshooting the dynamic environment of wastewater treatment processes and meeting regulatory compliance. As such, it’s important for sampling to be performed accurately, consistently, and in a location that is representative of the wastewater quality as a whole. The types of tests you perform, the number of samples taken, and the laboratory methods used to analyze these samples will depend on your system’s treatment type, chemical usage, equipment, and raw water quality. Results from the analysis will promote process optimization. A detailed copy of your facility’s sampling and testing procedures should be accessible in the utility Operations and Maintenance Manual for reference.

Featured Video: Replacing the Power Cord on a Sewage Pump

Submersible sewage pumps can be used for a variety of applications spanning the needs of residential homes to wastewater treatment plants depending on their size and design. A submersible pump is made up of a submerged motor filled with air or oil. Various impellers designs determine what sized solids the pump can handle.

In this week’s featured video, Chris with R.C. Worst & Co. demonstrates how to replace the power cord on a submersible sewage pump. This particular pump is designed for septic tanks and the sewage handling of commercial and residential applications. While working on the pump, he offers some tips and tricks that can help you to save money during repairs and prevent additional damage. As a bonus he discovers some unexpected factory damage and demonstrates how to repair broken wiring. If you need to fix a pump from your own system, remember that this sort of repair work should only be made by operators with the appropriate training. You can find hands-on pump training in your area by visiting our operator event calendar.

Featured Videos: Pump Curves and Pump Selection Basics

Pump curves inform operators to select and run pumps at optimal efficiency for their system. Whether preparing for a certification exam or looking to refresh your knowledge of pump hydraulics, this week’s featured videos will teach you how to read pump curves, calculate system curves, and use these curves to select an ideal pump for your system.

For any given pump, flow will impact pressure head, efficiency, horse power requirements, and vulnerability to pump damage. This video reviews three different pump curves starting with a very simple curve and moving to more complex curves with increasing pump information. Understanding performance, efficiency, horsepower, and net positive suction head (NPSH) curves is essential in selecting the proper pump for your system’s needs. After covering the basics, this video introduces concepts that will help operators to select and run pumps at recommended operating zones to maximize pump life and reduce operational costs.

Once you start to feel comfortable with these concepts, the next step is learning how to compare pump curves to your own system. For pump curves to be useful during selection, you must first have a system curve of your own. Prepare for a bit of math because this next video walks through the calculations needed to develop a simplified equation that graphs system pressure head (Hp) as a function of flow rate (Q) squared. When watching the video, remember that z1 is the starting elevation and z2 is the final elevation.

With a well developed knowledge of pump curves and system curves, selecting a new pump becomes much easier. This last video demonstrates how to compare the system curve to the pump curve . When comparing these two graphs, the pump’s best efficiency point should be fairly close to the system operating point. Other considerations include how much power is required to operate the pump and the net positive suction head available to avoid pump cavitation. 

These videos simplify many of the factors that go into a real system, however they offer a good foundation for operators to better understand the theory behind pump curves and pump selection.

What's on the Drinking Water Radar for the Year Ahead: 2019

Being a small-town water operator is not easy; it is up to you to ensure the quality of your community's water day-in and day-out, often with very limited resources. Let WaterOperator.org help you meet the challenge head-on with this list of tools and resources to put on your radar for the year ahead:

• Have you gotten in the groove yet with the new RTCR requirements? Here are two new documents from the USEPA designed to help small public water systems: Revised Total Coliform Rule Placards and a Revised Total Coliform Rule Sample Siting Plan with Template Manual. Additional compliance help, including public notification templates, a RTCR rule guide, a corrective actions guidance and more can be found here.
• While we know your hands are full just getting the job done, there are new and emerging issues you may have to deal with in the year ahead. For example, this past year many communities have been dealing with PFAS contamination issues. This ITRC website provides PFAS fact sheets that are regularly being updated on PFAS regulations, guidance, advisories and remediation methods. Especially of interest is this excel file that has begun to list the different state standards and guidance values for PFAS in drinking water as they are developed. Be sure to check back often for updates.
• Your utility may also have to adjust to new compliance rules in the coming year. In Michigan, for example, a new Lead and Copper Rule arising from the water crisis in Flint has gone into effect, making it the strictest in the nation. Other states, such as Ohio, have also adopted tougher standards, or are now requiring schools to test for lead. Oregon has established temporary rules that will require drinking water systems in the state using certain surface water sources to routinely test for cyanotoxins and notify the public about the test results.
• With a warming climate, these incidences of harmful algal blooms in surface water are on the increase, causing all sorts of challenges for water systems that now have to treat this contaminant. This cyanotoxin management template from the EPA can help assist you with a plan specific to your location.
• Worker turnover and retirements will still be an issue in 2019. According to this article, the median age for water workers in general (42.8 years) and water treatment operators specifically (46.4 years) are both above the national average across all occupations (42.2 years). You can keep transitions as smooth as possible by using EPA's Knowledge Retention Tool Spreadsheet and/or this Electronic Preventive Maintenance Log.
• New Tech Solutions: A UMass lab focusing on affordable water treatment technologies for small systems will be rolling out its Mobile Water Innovation Laboratory in 2019 for on-site testing. In addition, the facility is testing approaches to help communities address water-quality issues in affordable ways. "Early next year, in the maiden voyage of the mobile water treatment lab, UMass engineer David Reckhow plans to test ferrate, an ion of iron, as a replacement for several water treatments steps in the small town of Gloucester, MA.

But even without all these challenges and new ideas for the future, simply achieving compliance on a day-to-day basis can be tricky - if this sounds familiar, you may want to check out our recent video on how operators can approach the most common drinking water compliance issues.

Focus on Chemical Feed Control

Chemical dosing at the water treatment plant is a critical, but often underrated step in producing safe drinking water. Historically, process control points have focused on the hazards present in incoming source water - with emphasis on the filtration and disinfection steps to minimize microbial risks. But while many hazards do indeed enter the plant with the raw water, it is just as important to identify the multiple risks associated with treating this raw water.
