WaterNow Alliance: Leveraging Capital Markets to Accelerate Lead Service Line Replacements
2023-02-01 10:00 - 11:00 | Webinar Only
The new $15 billion in federal funding for lead service line replacements, as vital and historic as it is, is dwarfed by the estimated $47 billion need to address this public health crisis, one that affects primarily the most vulnerable and needy among us, often people of color. It is possible for local water leaders to close this funding gap. WaterNow Alliance and Environmental Policy Innovation Center will host a 1-hour virtual webinar for utility and community leaders nationwide on how they can access capital markets to maximize access to federal funding and accelerate the rate of lead line replacements on private property.
The webinar has 5 objectives:
1. Highlight the One Water and multiple community benefits of replacing lead service lines, particularly on private properties where they are the most prevalent and most likely to be harming disadvantaged households and communities of color.
2. Feature perspectives from capital market investors about their interest in investing in lead service line replacement programs as a sound investment and to accelerate these needed replacements and protect public health.
3. Equip participants with the knowledge of how to leverage local financing approaches to maximize access to federal dollars and accelerate the pace of replacements.
4. Feature a real-world case study from communities and utilities replacing lead service lines at a faster pace than most.
5. Answer questions about how to leverage capital markets for lead service line replacements.

RCAC - What You Need to Know About the Sustainable Groundwater Management Act
2023-04-19 10:00 - 12:00, 2023-04-19 14:00 - 16:00 | Webinar Only
Description: The Sustainable Groundwater Management Act of 2014 (SGMA) has been called “the most important legislation in California in 100 years.” SGMA mandates the sustainable use of California groundwater. Given the fact that many groundwater basins are in overdraft, implementation of sustainable practices will likely have a significant impact on small water systems that use groundwater from these basins. SGMA applies to the 127 high and medium priority groundwater basins, which account for approximately 96 percent of groundwater use in California. It is therefore very likely that a significant number of California small water systems will be impacted by the implementation of sustainable practices mandated by this law. Given that both Water Rights and Adequacy of Supply are Division of Drinking Water (DDW) Technical, Managerial and Financial (TMF) elements and that SGMA is very likely to have a significant impact on both these elements for a large number of California small water systems, it is very important that these systems have adequate training into SGMA’s process and requirements.
Participants will learn:

The basics of groundwater hydrology, including: The Water Cycle and types of aquifers
The provisions of SGMA, including: The goal of sustainable water extractions from a basin
What the groundwater sustainability plans are and how they might affect our operations
Strategies that may be used to achieve sustainability

The recommended audience includes water system managers, operators, administrative staff and board members.

EFCN - CWSRF Funding Process Virtual Workshop Series: Economics and Affordability of Low Interest Rate Loans
2023-04-20 09:00 - 10:00 | Webinar Only
Join experts from the Environmental Finance Center Network for a no-cost webinar series on the Clean Water State Revolving Fund (CWSRF). This monthly series is intended to help you better understand the CWSRF funding process.
Sessions will be held on the third Thursday every month (excluding December 2023 which will be held on Tuesday, December 19).
April 20, 2023 | Session 4: Taking on capital improvement projects can be expensive and often necessitates financing, such as loans. Since loans need to be paid back over time and may require rate increases to generate sufficient revenue for debt repayment, it is beneficial to decrease the interest and principal as much as possible. Subsidized low-interest rate loans, like the state Drinking Water or Clean Water State Revolving Funds (SRF), can save money over time by offering lower interest rates compared to market rates and, for qualifying communities, partial principal forgiveness. We recommend low interest loans because they decrease impacts on the customer base.
In this webinar, we will describe low-interest loans, their merits, and demonstrate two tools to help evaluate different loan options and their financial impact. We introduce the Subsidized Loan Calculator, which allows you to compare different loan options and their total and annual debt payments now and 30 years down the road. We will also demonstrate the Affordability Tool to illustrate how different customers may be impacted by rate increases necessary to pay back the loans. Finally, we will discuss a case study to consider why subsidized loans can be a good option for low-income communities.
Learning Objectives:

Available financing options to you for your capital improvement projects, and compare subsidized low-interest loans to market-rate loans
Evaluate different loan options based on interest rates and, if applicable, principal forgiveness terms
How to use the Subsidized Loan Calculator tool to compare low-interest rate and market-rate loans
Understand how taking on a loan can affect your customers, depending on the loan terms

Presenters: Kristen Downs, Project Director, UNC Environmental Finance Center

RCAC - Metering Replacement Plans
2023-04-20 10:00 - 12:00, 2023-04-20 14:00 - 16:00 | Webinar Only
Description: The water meter is the cash register for public water systems! Water systems need an accurate measurement of the water being used by their residential, commercial, and industrial customers or they could potentially be losing money. The accuracy is vital for planning all aspects of water system operations from budgeting, reporting to the primacy agency and planning for the short- and long-term future. It is crucial that the meters be replaced prior to a predetermined date (no more than 15 years) to ensure that the meters are still reading accurately. When replacing meters, the public water system may want to consider replacing manual read water meters with radio read, cellular read or other technology, which brings us to funding. Will we be funding this from our existing budget, or will we be seeking grant/loan money for a meter replacement project?
Participants will learn:

Different types, brands and styles of water meters and choosing the one best for your system
Proper application of water meters (types and size)
Installing a water meter
Budgeting for water meter replacement vs. loans/grants for water meter replacement
Manual read water meters vs. smart meters

The recommended audience includes board members, management and operators.

RCAC - Dealing with Forever Chemicals: PFAS in Drinking Water
2023-04-25 10:00 - 12:00 | Webinar Only
Description: The issue of PFAS contamination is being highlighted throughout the country with many experiencing anxieties over possible water contamination. PFAS are a group of man-made chemicals which include Perfluorooctanoic Acid (PFOA), Perfluorooctanesulfonic Acid (PFOS). Known as “forever chemicals” PFAS compounds have been found widely in the environment including thousands of groundwater sources throughout US.
PFAS compounds are currently the #1 emerging threat to water systems. Continuing studies are identifying potential health risks associated with these chemicals. This session examines the origin, the concerns, and provides information for small systems about protecting public health.
Participants will learn:

Why these “forever” chemicals are not going away
Where do PFAS come from
What are the health effects of PFAS
PFAS regulations in drinking water
PFAS treatment technologies for drinking water systems

The recommended audience includes board members, managers and operators.

EPA Small Drinking Systems Webinar: Manganese
2023-04-25 11:00 - 12:00
The U.S. Environmental Protection Agency’s Office of Research and Development and the Office of Water invites you to attend a free webinar on Manganese. There will be two parts to this webinar. For further information, view the flyer for the webinar HERE.
Presentation 1: Manganese Interference with Disinfectant Residual Methods
This presentation will provide a summary of manganese occurrence in public water systems and describe its potential interference with commonly used methods to measure disinfectant residual. Case studies will be shared to demonstrate this issue. A flow chart to diagnose manganese interference will be introduced to help identify approaches to minimize manganese interference with commonly used methods, including sample pre-treatment, sample filtration, and alternative methods.
Presentation 2: Management of Manganese and Small System Considerations
Treatment of manganese is an ongoing concern for operational, esthetic and, more recently, health reasons. Manganese has been shown to be accumulated and released from the distribution system. These release events can cause discolored water but also release other regulated metals of health concern (e.g. lead, arsenic) into the distributed water. Research indicates that a finished water concentration of <0.02 mg/L is achievable by most utilities by optimizing existing treatment. At this concentration, it can also help minimize the accumulation (and subsequent release) of manganese into the distributed water. This presentation will outline management strategies for manganese including small system considerations.
Who should attend?: State, and territory, and tribal personnel responsible for drinking water regulations compliance and treatment technologies permitting, water system operators, technical assistance providers, local government personnel, and others may benefit from attending.
