FOR: Water Subcommittee Meeting [May 29, 2024] TO: Honorable Water Subcommittee Members
APPROVAL: Tanya Williams, Assistant City Manager
Request the Water Subcommittee authorize the City Manager and the City Attorney to Enter Into Negotiations for Agreement to Pursue PFAS Settlement Funds for the Baseline Feeder System. (ACTION)

BACKGROUND
The San Bernardino Valley Municipal Water District (District) proposes a joint agreement among the City of Rialto (City), the Riverside Highland Water Company (RHWC), and the West Valley Water District (West Valley) (jointly, the Parties) to pursue a claim from the national PFAS litigation settlement fund to address potential future discoveries of PFAS contamination in the Baseline Feeder System, which provides water supplies to the Parties. We recommend that the Subcommittee authorize the City Attorney to enter into negotiations for the proposed joint agreement.

A. The Baseline Feeder System
The Baseline Feeder System (Baseline Feeder) is a facility that delivers water from the southern and central part of the San Bernardino Basin to various users. The Baseline Feeder, which was originally built in around 1990 and was extended deeper into the City between 1991 and 1992, is comprised of pipelines and related facilities. The District financed the construction of the Baseline Feeder through bonds and loans, and the other three Parties have been making annual payments to the District since July 2012 in renumeration of these bonds and loans. The City has paid about $173,000 annually in reimbursement costs, pursuant to the May 2012 Baseline Feeder System Agreement (2012 Agreement) between the Parties that formalized their respective obligations. At these rates, the City will pay off its share of the Baseline Feeder’s capital reimbursement costs in July 2041. The 2012 Agreement also calculated each party’s monthly costs for the water supply provided by the Baseline Feeder using calculations of annual unit water costs and the quantity of water delivered to each party.

The City has paid $14,410.28 monthly since July 2012 for water supply delivered via the Baseline Feeder.

The 2012 Agreement provided that the District would construct, operate, and own the Baseline Feeder System at no cost to the District. The aforementioned annual and monthly payments from the City and the other parties to the District implement this directive. The 2012 Agreement also contains mutual indemnity provisions and reiterates that it governs only the Baseline Feeder, not the Parties’ various connections thereto.

B. PFAS: “Forever Chemicals”
City of Rialto Printed on 5/24/2024Page 1 of 3
powered by Legistar™

Per- and polyfluoroalkyl (PFAS) substances are artificial chemicals that have been used extensively since the 1940s, especially in nonstick cookware, water-repellant clothing, stain resistant textiles and materials, some cosmetics and firefighting foams, and in products designed to resist grease, water, and oil. Because of their resilience, PFAS chemicals migrate easily through water, air, and soil, and PFAS are now found in human and animal blood worldwide, as well as in many food products and across the environment. The scientific data on the human health risks associated with exposure to PFAS chemicals is still being developed, but preliminary data suggests that long-term exposure to PFAS can cause adverse effects. Workers in facilities handling PFAS may have greater risks, as well as young children that have weaker immune systems and that are prone to ingestion of PFAS- containing items.

C. The National PFAS Litigation Settlement
In March 2024, the federal court overseeing the nationwide multidistrict litigation against the 3M and DuPont companies regarding PFAS drinking water contamination approved a final settlement resolving the case. The class-action litigation sought damages for the costs of testing and monitoring for ongoing PFAS contamination in drinking water; the costs of designing, constructing, installing, operating and maintaining filtration systems; and the costs of complying with any applicable regulations requiring further measures to address PFAS contamination in drinking water.

Per the settlement, 3M and DuPont will pay between $10.5 billion and $12.5 billion to members of the “Settlement Class” in exchange for a releases, dismissals, and covenants not-to-sue for PFAS- related drinking water claims. Notably, the “Settlement Class” includesevery active public water system in the United States that either has PFAS-contaminated water sources as of June 22, 2023, or does not have PFAS-contaminated water sources as of June 2023, but is required to test for PFAS under the Safe Drinking Water Act or serves more than 3,300 people.

The settlement requires that funds be disbursed to those public water systems with PFAS- contaminated water sources first, followed by the remaining systems. The funds are allocated 55 percent to the systems with current contamination, and 45 percent to those systems without confirmed contamination yet. The funding is further broken down into categories based on past testing and remediation costs and future possible testing and remediation costs. To receive compensation, water systems will be required to submit claims forms indicating flow rates and levels of PFAS contamination. A claims administrator will then use mathematical formulas to determine the compensation due a particular claimant.

The deadline for systems that detect PFAS in their water sources after June 2023 is January 1, 2026 to receive funds for PFAS testing, and between June 30 and July 31, 2026 for post-testing remediation funding. All other systems will have until December 31, 2030, to test for PFAS and receive remediation funding.

ANALYSIS/DISCUSSION
No PFAS have been detected in the Baseline Feeder yet, and so the Baseline Feeder would qualify as a Phase 2 claimant. The District is proposing that it pursue the Phase 2 PFAS settlement proceeds from the 3M/DuPont settlement as operator of the Baseline Feeder. However, consistent with the 2012 Agreement, the District maintains that it must not incur any costs or expenses in pursuing the claim. Within 60 days of being awarded/receiving any settlement funds, the parties will City of Rialto Printed on 5/24/2024Page 2 of 3

9 File #: WS-24-1467, Version: 1, Agenda #:
meet and confer regarding how to disburse the funds. The funds must be restricted to remediating PFAS contamination and related activities in the Baseline Feeder.

We recommend that the City accept the District’s proposal. The District is the owner and operator of the Baseline Feeder, and is the appropriate entity to submit a claim for any PFAS contamination that may be discovered in the system in the future. However, there are several items we need to clarify with the District before accepting the proposal:

1. First, it is unclear who will pay the legal and administrative costs of submitting a PFAS settlement claim if the District will not finance these expenses. Presumably these costs would be levied from, or in addition to, the Parties’ monthly payments to the District.

2. Will the water supply and payment disbursement calculations in the 2012 Agreement inform how the PFAS settlement funds received, if any, will be distributed among the Parties? Alternatively, if the settlement funds are restricted to the Baseline Feeder, does the District as system operator retain the funds for conducting remediation?

3. If the PFAS settlement funds are restricted to the Baseline Feeder, will the City need to file individual claims for PFAS contamination in its systems that are not part of the Baseline Feeder?

4. The mutual indemnification provisions of the 2012 Agreement provide that each party indemnifies the other for claims arising out of the operation of their individual systems.

Does this require the District to indemnify the City for any PFAS that migrates into the City’s system from the Baseline Feeder?
We believe that most of these issues can be resolved through negotiation with the District and the other parties, and should not foreclose consideration of an agreement. The City Attorney’s office will return with a final proposed agreement for the City to consider before execution.

APPROVAL: Tanya Williams, Assistant City Manager

Request the Water Subcommittee provide feedback on using West Valley Water Rights in Combined Remedy. (ACTION)

BACKGROUND
In 2012, the City of Rialto/Rialto Utility Authority (City/RUA) and Rialto Water Services (RWS)/Veolia entered into a service contract referred to as the Concession Agreement (CA) for the design, construction, and financing of capital improvement upgrades and the operation and maintenance of RUA facilities.

The Concession Agreement provides, in part, that RWS shall operate and maintain the Rialto Water System, except for the treatment of perchlorate and other contaminants not complying with certain drinking water standards. Pursuant to the Concession Agreement, the City/RUA is responsible for equipping groundwater wells with wellhead treatment for purposes of addressing the perchlorate and other contaminants not complying with drinking water standards. It is the responsibility of the City/RUA to operate and maintain the treatment systems for various wells prior to water entering into the Rialto Water System.

In September 2010, the United States Environmental Protection Agency (EPA) issued the Interim Action Record of Decision to the Source Area Operable Unit (SAOU) of the B.F. Goodrich Superfund Site, now referred to as the “Rockets,Fireworks, and Flares Superfund Site.” The EPA’sRemedy for the SAOU required Emhart Industries to install, operate, and maintain a groundwater pump and treatment system to intercept and control the spread of contaminated groundwater from the 160-acre parcel. The EPA Remedy is designed to capture and remove perchlorate and trichloroethylene (TCE) in the groundwater in the Rialto-Colton Groundwater Basin (Basin) emanating from a 160-acre parcel located in north Rialto.

Effective September 1, 2015, the City/RUA entered into a Four-Party Implementation Agreement (Implementation Agreement) with Emhart Industries (Emhart), the County of San Bernardino (County), and the City of Colton (Colton), to implement the interim remedial action plan as required by the Consent Decree as entered on July 2, 2013. The remedial action required by the Work Consent Decree was selected and approved and is overseen by the EPA.

The County and Emhart agreed that the EPA Remedy would be combined with an existing groundwater extraction and treatment remedy designed and constructed by the County to capture and remove perchlorate and TCE in the Basin due to the Mid Valley Landfill and required by the Santa Ana Regional Water Quality Control Board (Regional Board). This combined project is referred City of Rialto Printed on 5/24/2024Page 1 of 4
powered by Legistar™
18 File #: WS-24-1459, Version: 1, Agenda #:

Santa Ana Regional Water Quality Control Board (Regional Board). This combined project is referred to as the Combined Remedy Project.

The Combined Remedy Project included:

1. Installing a new extraction well (EW-1), located at the northwest corner of Jerry Eves Park, and piping to the water treatment system located at the northeast corner of Miro Way and Linden Ave.,

2. Expanding the existing County groundwater treatment system at the Rialto 3 Well site to treat extracted water from EW-1, referred to as the Combined Remedy Treatment Facilities,

3. Upgrading the chlorination station at the Combined Remedy Treatment Facilities site,

4. Constructing an inter-tie between Rialto and Colton to deliver Colton’s water rights produced out of EW-1, and

5. Implementing improvements to Colton’s drinking water distribution system, specifically modifications made by Emhart to a reservoir and pump station.

One of the requirements of the project was to revise the City/RUA’sdrinking water permit to include the Combined Remedy Project. On or about September 18, 2019, the City/RUA applied to the State Water Resources Control Board Division of Drinking Water (DDW) for an amendment to the Permit.

Part of the purpose of the amendment was to add EW-1 as a groundwater source and add the expansion of an Ion Exchange (IX) and Granular Activated Carbon (GAC) treatment units at the Combined Remedy Treatment Facilities as an approved treatment for EW-1, Rialto 3, and Miro 3 wells.

After a couple of years of discussions and providing documents and studies to the DDW, on September 15, 2022, the DDW issued a final amendment to the City/RUA’spermit. Full operation of the Combined Remedy Project began in January 2023, with the approval of the City Council/Rialto Utility Authority Board of an agreement with Veolia Water West Operating Services, Inc (Veolia) to operate and maintain the Combined Remedy Project and the Chino No. 2 Treatment System on December 13, 2022.

ANALYSIS/DISCUSSION
On April 30, 2024, Emhart reached out to the City/RUA about an arrangement regarding the temporary use by Emhart and Rialto of certain West Valley Water District (WVWD) water rights in the Rialto-Colton Basin (RCB) to implement the remedy for Operable Unit 1 (OU1) of the Rockets, Fireworks, and Flares Superfund Site (RFF Site).

On May 15, 2024, staff met with the County, Emhart, and West Valley Water District to discuss the remedy for OU1. WVWD advised that it has 1,000 acre-feet (AF) of RCB water rights for the October 2023 through September 2024 water year.

The group collectively agreed pending notification to its governing bodies that:

1. Rialto, in consultation with Emhart, would arrange to pump up to the amount available from WVWD, from EW-1, using WVWD RCB water rights, and will inform Emhart and WVWD on a monthly basis of the amount pumped using such rights.

2. Rialto would keep the water pumped at EW-1 using WVWD water rights in Rialto’s municipal water supply system for distribution to its customers and, in exchange, WVWD would retain in its municipal water supply system, an equivalent amount of water produced at the Roemer treatment plant that it would have otherwise delivered to Rialto via the Cedar intertie.

3. Rialto would be responsible for the lifting (electrical) costs of pumping the WVWD rights at EW City of Rialto Printed on 5/24/2024Page 2 of 4
powered by Legistar™
19 File #: WS-24-1459, Version: 1, Agenda #:

3. Rialto would be responsible for the lifting (electrical) costs of pumping the WVWD rights at EW -1, and WVWD would bear no cost associated with the production of such water. Rialto would not pay WVWD for water that would otherwise be delivered via the Cedar intertie but that is not delivered under this arrangement.

This item is administrative and operational in nature; therefore, it does not require Council or Board approval.

ENVIRONMENTAL IMPACT
This request is not a “Project”as defined by the California Environmental Quality Act (CEQA).

Pursuant to Section 15378(a), a “Project”means the whole of an action, which has a potential for resulting in either a direct physical change in the environment, or a reasonably foreseeable indirect physical change in the environment. According to Section 15378(b), a Project does not include: (5) Organizational or administrative activities of governments that will not result in direct or indirect physical changes in the environment.

GENERAL PLAN CONSISTENCY
Approval of the proposed action also complies with the following City of Rialto Guiding Principles, General Plan Goals and Policies:

Our City government will lead by example, and will operate in an open, transparent, and responsive manner that meets the needs of the citizens and is a good place to do business.

Goal 3-8: Promote affordable and quality water service capable of adequately meeting normal and emergency water demands to all areas in Rialto.

Policy 3-8.4: Advocate regular evaluation of the entire water supply and distribution system to ensure its continued adequacy, reliability, and safety.

LEGAL REVIEW
The City Attorney’s Office has reviewed the staff report.

FINANCIAL IMPACT
Operating Budget Impact
There is a net zero change in the operating budget because the costs associated with pumping water are offset by the reduction in other costs, resulting in no overall budgetary impact.

Capital Improvement Budget Impact
There will not be any impact on the Capital Improvement Budget from the proposed action.

Licensing
Payment of a Business License tax is not required for the proposed action.

Request that the Water Subcommittee provide feedback on the 2023 Consumer Confidence Report for Drinking Water. (ACTION)

BACKGROUND
In 1996, the United States Congress amended the Safe Drinking Water Act by adding a provision requiring all community water systems to deliver a brief annual water quality report. The annual report is referred to as a Consumer Confidence Report (CCR) and is delivered to customers annually no later than July 1st.

The CCR includes information on our source water, the levels of any detected contaminants for the calendar year, compliance with drinking water rules, plus educational material.

The online availability of the Annual Consumer Confidence Report, created by Rialto Water Services (RWS), is sent to customers in the message box of their water bill. It explains that the report is online on the RWS website and can be obtained as a hard copy from certain City facilities. Customers can also request a copy by mail through their billing statements.

ANALYSIS/DISCUSSION
Since 1990, California public water utilities have provided an annual Consumer Confidence Report to their customers. This year’sreport covers the calendar year 2023 drinking water quality testing and reporting. RWS, as operated by Veolia of North America vigilantly safeguards our water supply and, as in years past, the water delivered to the homes and businesses met the quality standards required by Federal and State regulatory agencies. The United States Environmental Protection Agency (USEPA) and the California Department of Public Health (CDPH) are the government agencies responsible for establishing and enforcing drinking water quality standards.

ENVIRONMENTAL IMPACT
This request is not a “Project”as defined by the California Environmental Quality Act (CEQA).

GENERAL PLAN CONSISTENCY
Approval of the proposed action also complies with the following City of Rialto Guiding Principles, General Plan Goals and Policies:

Our City government will lead by example, and will operate in an open, transparent, and responsive manner that meets the needs of the citizens and is a good place to do business.

Goal 3-8: Promote affordable and quality water service capable of adequately meeting normal and emergency water demands to all areas in Rialto.

Policy 3-8.4: Advocate regular evaluation of the entire water supply and distribution system to ensure its continued adequacy, reliability, and safety.

LEGAL REVIEW
The City Attorney’s Office has reviewed the staff report.

FINANCIAL IMPACT
Operating Budget Impact
The cost related to distributing the CCR is low because it's mainly done through the RWS website and advertisement of its availability is done through the already established medium of the monthly water bill.

Capital Improvement Budget Impact
There will not be any impact on the Capital Improvement Budget from the proposed action.

Licensing
Payment of a Business License tax is not required for the proposed action.

FACTS ABOUT OUR WATER SYSTEM

 In 2023, 74% of our total potable drinking water was
sourced from our ground water basins, 16% from the
Baseline Feeder (BLF) and 10% was surface water.

 Number of Water Service Connections = 12,080

 Miles of Water Main = 186.5

 Number of Producing Wells = 7

 Total Reservoir Capacity = 28 million gallons

 Maximum Daily Production = 16.054 million gallons

 Minimum Daily Production = 1.458 million gallons

 Average Daily Production = 8.749 million gallons

 Total Annual Production = 3.978 billion gallons
25 What is surface water?

It is any water that travels or is stored on top of the ground.

This would be the water that is in rivers, lakes, streams, oceans--even though we can’t drink salt water. Sometimes surface water sinks into the ground and becomes ground
water. Surface water is treated before it becomes drinking water.

What is ground water?

Any water that is under ground is ground water. In the
water cycle, some of the precipitation sinks into the
ground and goes into watersheds, aquifers and springs.

Ground water flows through layers of sand, clay, rock, and gravel which cleans the water. Ground water stays cleaner than water on the surface and does not need as much
treatment as surface water.

Perchlorate Information

Rialto has a zero tolerance policy regarding water that contains detectable levels of perchlorate.

We currently have wellhead treatment on two of our
wells for the removal of perchlorate. This wellhead
treatment removes the perchlorate to a non-detection
level. The other wells affected by perchlorate
contamination have been out of service and have not
been used since the detection occurred. These
responses, especially the installation of ion exchange
water treatment systems, have produced a measure of
success that has allowed the City to reliably deliver
potable water to all of its customers.

The City of Rialto urges all of its residents to continue conserving water and to look for new ways to reduce
the demand in our system. The City of Rialto continues
to work with those responsible for the contamination
to remediate perchlorate contamination in the water
supply.

Contaminants That May be Present in
Source Water:

Microbial contaminants, such as viruses and bacteria that may come from sewage treatment plants, septic systems,
agricultural livestock operations, and wildlife.

Inorganic contaminants, such as salts and metals, that can be naturally-occurring or result from urban stormwater runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farming.

Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban stormwater runoff and residential uses.

Organic chemical contaminants, including synthetic and
volatile organic chemicals, which are byproducts of
industrial processes and petroleum production, and can, also, come from gas stations, urban stormwater runoff,
and septic systems.

Radioactive contaminants can naturally occur or be the
result of oil and gas production and mining activities.

Contaminants Expected in Drinking
Water
Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some
contaminants. The presence of contaminants does not
necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the U.S. EPS’s Safe Drinking Water Hotline (1-800-426-4791).

People Most Vulnerable To
Contaminants
Some people may be more vulnerable to contaminants in
drinking water than the general population. Immune -
compromised persons such as persons with cancer
undergoing chemotherapy, persons who have undergone
organ transplants, people with HIV/AIDS or other immune disorders, some elderly, and infants can be particularly at risk from infections. These people should seek advice about
drinking water from their health care providers. U.S.

EPA/Centers for Disease Control (CDC) guidelines on
appropriate means to lessen the risk of infection by
Cryptosporidium and other microbial contaminants are
available from the Safe Drinking Water Hotline (1 -800-426- 4791).

Contaminant Information
If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children.

Lead in drinking water is primarily from materials and
components associated with service lines and home plumbing.

The City of Rialto is responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing components. When your water has been sitting for several hours, you c an minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water for drinking or cooking. If you do so, you may wish to collect the flushed water and reuse it for another beneficial purpose, such as watering p lants. If you are concerned about lead in your water, you may wish to have your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline or at
hhtp://www.epa.gov/lead.
26 CITY OF RIALTO WATER QUALITY RESULTS FOR 2023
The State allows us to monitor for some contaminants less than once per year because the concentrations of these contaminants do not change frequently.

Some of our data, though representative, are more than one year old.

Terms Used in This Report

Maximum Contaminant Level (MCL):

MCL is the highest level of a contaminant that is allowed in drinking water. Primary MCLs are set as close to the PHGs (or MCLGs) as is economically and technologically feasible. Secondary MCLs are set to protect the odor, taste, and appearance of drinking water.

Maximum Contaminant Level Goal (MCLG):

The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs are set by the U.S.

Environmental Protection Agency (USEPA).

Public Health Goal (PHG):

The level of a contaminant in drinking water below which there is no known or expected risk to health. PHGs are set by the California Environmental Protection Agency.

Maximum Residual Disinfectant Level (MRDL):

The level of a disinfectant added for water treatment that may not be exceeded at the consumer’s tap.

Maximum Residual Disinfectant Level Goal (MRDLG):

The level of a disinfectant added for water treatment below which there is no known or expected risk to health. MRDLGs are set by the U.S. Environmental Protection Agency.

Primary Drinking Water Standards (PDWS):

MCLs and MRDLs for contaminants that affect health along with their monitoring and reporting requirements, and water treatment requirements.

Secondary Drinking Water Standards (SDWS):

MCLs for contaminants that affect taste, odor, or appearance of the drinking water. Contaminants with SDWSs do not affect the health at the MCL levels.

30 Water and Employee Quality

Rialto Water Services is proud to inform residents that the Water Division has passed another annual water quality checkup. City of Rialto Water has met all the Clean Water Standards set forth by the State and Federal Governments in 2004. Part of meeting these requirements is having California Water Resources Control Board and American Water Works Association (AWWA) certified employees in water distribution, treatment and cross connection/ backflow protection. Certifications are obtained by taking college level courses in water science and engineering. We have entered into a collective bargaining agreement that has placed even higher standards on operators and certification levels. In addition, staff continues to upgrade certifications as a part of our continuing education program. State and federal certifications allow us to operate and maintain the public water system for the City of Rialto. This is just one of the many committed efforts we put towards producing clean drinking water for our customers.

Help Us Conserve This Precious Resource

• 2023 was a wetter year than previous years, but there is still a need to conserve this precious resource. Surface water levels are not back to normal and groundwater basins, where much of Rialto’s water comes from, are still depleted from the continuing drought. We all play an important role in meeting conservation targets set by the state, whether at home or work. Please review these simple water
conservation tips and help us conserve this, our most
precious natural resource.
• Fill washing machines and dishwashers before running
them. Partial loads use the same amount of water as full loads. You can save up to 1,000 gallons a month.
• Little leaks add up in a hurry. A dripping faucet or a toilet leak can add up to hundreds of gallons of wasted water.
• Turn off the water while you brush your teeth. You can save up to 500 gallons a month.

• Be sure to use low-flow showerheads and install aerators on your kitchen and bathroom faucets. They restrict the flow without compromising water pressure. You can save up to 750 gallons a month.
• Do not use a hose outside to clean sidewalks and
driveways; instead use a broom.
• Follow the Stage 2 Water Alert restrictions issued by the City.

No violations were received during this reporting period.

D. Source Water Total Dissolved Solids (TDS)
Veolia has a goal of maintaining an acceptable blended TDS level between all its sources. This goal is achieved by shifting production to or from the lowest TDS wells or purchased low TDS water while adhering to the overall water supply strategy and meeting system demands. The TDS was 233 mg/L for the month of March as compared to 254 mg/L in February. The TDS levels are below the secondary maximum contaminant level requirements.

VI. WATER QUALITY COMPLAINTS
No complaints were received during this reporting period.

VII. OPERATIONS UPDATE
The overall operational strategy is to meet the daily water demand. The City of Rialto water system has six operational wells, one of which is owned by the County of San Bernardino and operated by Veolia; Oliver P. Roemer Treatment Plant (OPRTP), which is jointly owned by the City (25%) and West Valley Water District (WVWD); purchased water through the Baseline Feeder (BLF) system from San Bernardino Valley Municipal Water District (SBVMWD); and, if required to meet demand, additional water can be supplied by the City of San Bernardino (CSB) through the BLF for emergency supply only with no guarantee of actual delivery. Water produced from City Well 4A discharges into the BLF and its production is included in deliveries from that shared transmission line when City Well 4A is in service.
59 The overall pumping strategy is based on adjudicated rights, well availability, remediation requirements, and quality of source, cost to operate, and varying weather conditions. TDS effluent concentrations for the City of Rialto WWTP are taken into consideration when operating the facilities and water sources.

A. Operational Wells
All wells were operational.

B. Valve Activity
On the basis of information collected in 2019, Veolia now has a baseline assessment of all valves and has initiated a new cycle of valve exercising. 31 valves were exercised for the month of March.
