Protecting Infrastructure and Reuse Reliability: Integrated Adaptive Plan for Odor, Corrosion, and UVT (Collections Reliability)

The City of Modesto operates a 20 MGD two-plant treatment system, with primary treatment at the Sutter Plant and secondary/tertiary treatment at the Jennings Plant. In recent years, the City has faced escalating odor complaints near Sutter, severe hydrogen sulfide (H₂S)-driven corrosion at Jennings, and seasonal ultraviolet transmittance (UVT) drops that jeopardize recycled water compliance. This study integrated field investigations, bench testing, and technology evaluations to develop an adaptive, tiered plan addressing all three challenges concurrently.

Comprehensive monitoring in four major trunk sewers and both plants quantified sulfide mass loads, confirmed two major trunks as dominant contributors (>80% of load to Sutter), and documented extreme H₂S levels at Jennings—averaging over 100 ppm and peaking above 700 ppm at fine screens. UVT declines were found to coincide with seasonal blending of high-BOD, low-pH cannery wastewater with domestic flows, introducing lignins, tannins, and potentially UV-absorbing artificial sweeteners. LC-MS confirmed the presence of five sweeteners in UV influent, though their individual impacts remain to be quantified.
A broad suite of odor/corrosion control options was screened against technical, operational, cost, and UVT-risk criteria. Chemicals with potential toxic by-products or proven UVT impairment were eliminated. Life-cycle analysis showed pure oxygen injection to be 3–6x less costly than chemical dosing for major trunk applications, with nanobubble oxygenation offering potential dual benefits for odor suppression and UVT improvement.

Bench-scale ECO₂ oxygenation tests validated rapid, complete dissolved sulfide removal within 30 minutes and confirmed low oxygen uptake rates, supporting conservative system sizing. The recommended adaptive plan applies a tiered approach: (1) immediate oxygen injection installation at Woodland and Thousand Oaks lift stations; (2) Sutter biofilter optimization, and nanobubble pilot testing; (3) targeted force main treatment via nanobubbles, oxygen injection, or nitrate dosing; and (4) end-of-line H₂S capture at Jennings via biotrickling filters.

Parallel UVT mitigation tiers included reverse blending to isolate cannery flows, nanobubble piloting, targeted compound source characterization, and long-term industrial source control via pretreatment or sewer-use by-laws. This integrated, data-driven strategy enables Modesto to phase investments, respond adaptively to performance data, and meet both odor/corrosion and recycled water reliability goals within operational and financial constraints.

Learning Objectives:
After the presentation, participants will be able to diagnose odor, corrosion, and UVT challenges using field data and source identification techniques
After the presentation, participants will be able to compare the cost, performance, and UVT impacts of chemical, oxygen, and nanobubble treatment strategies
After the presentation, participants will be able to apply a tiered, integrated and adaptive planning framework to phase solutions that protect infrastructure and protect recycled water reliability"

From Failing Septic Systems to Sustainable Futures: Sewer Solutions for Disadvantaged Communities in Sacramento County (Collections Reliability)

A new tool is available for concrete cylinder force main condition assessment: electromagnetic (EM) thickness testing. This tool does not require destructive methods that increase risk and defeat the purpose of assessment, nor does it require deployment of equipment on the inside of the pipe. V&A is piloting a technique developed in the oil and gas industry to use an EM probe on the outside of the pipe to measure metal thickness. Ross Valley Sanitary District's seven-mile force main system is about 42% reinforced concrete cylinder pipe (RCCP), with a steel cylinder surrounded by cement and outside steel reinforcing, installed between 1958 and 1986. RVSD would prefer avoidance of costly replacement if a non-destructive condition assessment technique would indicate more years of remaining service. The application of EM testing to a section of RCCP pipe along a known corrosion gradient will be presented, along with costs, equipment, procedures and results, and the potential application of EM testing in RVSD's broader condition assessment program will be discussed.

Learning Objectives:
Understand electromagnetic testing equipment, procedures, and costs, and how they relate to metal thickness of force main assets and their remaining useful life.
Understand how the study of a gradient of defective pipe, using corroded section of bypass force main, demonstrated the usefulness and sensitivity of EM testing to measure metal pipe thickness.
Evaluate whether to invest in electromagnetic testing as a targeted condition assessment tool and compare it with other force main condition assessment techniques and force main management approaches."

A New Tool for Concrete Cylinder Force Main Condition Assessment - External Electromagnetic Thickness Testing (Collections Reliability)

The Sacramento Area Sewer District (SacSewer) spearheaded a critical infrastructure project to replace failing septic systems with public sewer service in five small, disadvantaged communities in Sacramento County. Many of the replaced septic systems were beyond their useful lifespan, unpermitted, or unable to meet modern regulatory standards, posing risks to public health and the environment. The project constructed approximately 51,660 linear feet of new sanitary sewer pipelines, enabling households to abandon outdated septic systems and connect to reliable public sewer service.

Given the financial hardships faced by these low-income communities, SacSewer successfully pursued local, state, and federal grant funding and other cost-sharing assistance to make sewer conversion available at no cost to the residential and school properties in these communities. This effort required extensive community engagement and education with the goal of residents and property owners understanding that converting to sewer service would not only alleviate septic system maintenance burdens and avoid increasingly stringent septic regulations, but also protect groundwater, bolster public health, and enhance their property values. SacSewer expects construction to conclude by the end of 2025 with successful implementation ensuring long-term environmental protection and equitable access to essential wastewater services in Sacramento County.
Presenters will share lessons learned in securing and coordinating funding, managing project schedules, and designing effective community engagement strategies.

Key takeaways will include:
• How to approach and structure successful funding applications and coordinate with multiple funding agencies

Generative AI for Operations and Maintenance for Utilities (AI/Instrumental & Control) 
Water and wastewater utilities face mounting challenges—aging infrastructure, workforce shortages, and increasing operational complexity. Generative AI is emerging as a transformative tool to support operations and maintenance (O&M) by making institutional knowledge more accessible, improving decision-making, and boosting workforce efficiency.

This session presents the development and deployment of a domain-specific Generative AI platform for utility O&M. The goal is to show how large language models (LLMs), integrated with structured utility data, can assist field crews, operators, and engineers in real time. The system—called a Knowledge Twin—uses retrieval-augmented generation (RAG) to deliver accurate, actionable responses to natural language queries on assets, procedures, alarms, and troubleshooting.

Currently piloted with multiple utilities, the platform accommodates varying levels of data maturity. Data sources such as CMMS records, SCADA logs, SOPs, GIS data, and work order histories are ingested, structured into a knowledge graph, and connected to a fine-tuned LLM trained on the terminology, context, and workflows unique to water and wastewater operations.

Early results show that field staff can resolve issues faster, locate information more easily, and preserve institutional knowledge despite staff turnover. Use cases include alarm response guidance, step-by-step maintenance support, asset history retrieval, and on-demand training. A key finding is the system’s ability to uncover insights from previously siloed or underused data, reducing time-to-resolution and unplanned downtime.

The approach is designed to start small—focusing on high-impact use cases—and scale as more data is curated or digitized. This lowers the barrier to entry, enabling utilities of all sizes to leverage AI without perfect datasets or major system changes.

The session will feature a live demonstration, practical deployment considerations, and lessons from early adopters. Attendees will leave with a clear understanding of how Generative AI can be safely and effectively implemented to enhance daily O&M, improve service reliability, and strengthen workforce capabilities.

As utilities confront aging infrastructure and the demands of digital transformation, Generative AI provides a powerful path to future-proof operations and empower the next generation of utility professionals.

Session 2: Bottlenecks and Breakthroughs: Developing AI Models for Optimizing Calera Creek’s Wastewater Treatment Operations
Arup and the City of Pacific worked together to develop two AI/ML models as proof of concepts for sequential batch reactor (SBR) and auto-thermal thermophilic aerobic digestion (ATAD) operations at the Calera Creek Water Recycling plant. Arup and City of Pacifica first identified opportunities through visualizing historic plant data and then developed, trained, and tested chosen models. The project conclusions highlight barriers to implementation of AI/ML in plant operations, and identified necessary next steps to overcome these obstacles.

The Calera Creek Water Recycling Plant, located in Pacifica, California, is a critical facility that uses advanced SBR technology to efficiently combine aeration and clarification processes and ATAD technology to produce Class A sludge. These technical innovations allow the plant to meet the evolving challenges of wastewater treatment, nutrient removal, and environmental sustainability.

With the increasing complexity of its operations—especially during peak storm flows—there are a growing number of opportunities for advanced analytics, rooted in Artificial Intelligence and Machine Learning techniques, to optimize the plant’s operations. These include improving energy efficiency, enhancing process performance, and reducing the risk of unexpected faults or failures through managed predictive maintenance. This presentation will include insights from the Engineers, Operators, and Data Scientists’ perspective, as well as lessons learned from the project team when addressing challenges in developing optimization approaches towards SBR and ATAD operation.

The presentation will also cover how to effectively incorporate stakeholder input, pivot when presented with ambivalent results, and create roadmaps for effective integration of AI models in wastewater treatment plant operation.

Learning Objectives:
Develop strategies to encourage AI integration with existing wastewater treatment processes.
Recongnize bottlenecks to predictive AI/ML modeling for sequential batch reactor (SBR) and auto-thermophilic aerobic digester systems.
Manage uncertainty surrounding wastewater treatment plant data availability and quality."

Session 3: Generative AI for Operations and Maintenance for Utilities
Water and wastewater utilities face mounting challenges—aging infrastructure, workforce shortages, and increasing operational complexity. Generative AI is emerging as a transformative tool to support operations and maintenance (O&M) by making institutional knowledge more accessible, improving decision-making, and boosting workforce efficiency.

This session presents the development and deployment of a domain-specific Generative AI platform for utility O&M. The goal is to show how large language models (LLMs), integrated with structured utility data, can assist field crews, operators, and engineers in real time. The system—called a Knowledge Twin—uses retrieval-augmented generation (RAG) to deliver accurate, actionable responses to natural language queries on assets, procedures, alarms, and troubleshooting.

Currently piloted with multiple utilities, the platform accommodates varying levels of data maturity. Data sources such as CMMS records, SCADA logs, SOPs, GIS data, and work order histories are ingested, structured into a knowledge graph, and connected to a fine-tuned LLM trained on the terminology, context, and workflows unique to water and wastewater operations.

Early results show that field staff can resolve issues faster, locate information more easily, and preserve institutional knowledge despite staff turnover. Use cases include alarm response guidance, step-by-step maintenance support, asset history retrieval, and on-demand training. A key finding is the system’s ability to uncover insights from previously siloed or underused data, reducing time-to-resolution and unplanned downtime.

The approach is designed to start small—focusing on high-impact use cases—and scale as more data is curated or digitized. This lowers the barrier to entry, enabling utilities of all sizes to leverage AI without perfect datasets or major system changes.

The session will feature a live demonstration, practical deployment considerations, and lessons from early adopters. Attendees will leave with a clear understanding of how Generative AI can be safely and effectively implemented to enhance daily O&M, improve service reliability, and strengthen workforce capabilities.

As utilities confront aging infrastructure and the demands of digital transformation, Generative AI provides a powerful path to future-proof operations and empower the next generation of utility professionals.

Learning Objectives:
1. Understand what Generative AI is and how it applies specifically to utility operations and maintenance.
2. To see key operational use cases where Generative AI delivers measurable value.
3. To understand how AI tools using existing utility data—regardless of current data maturity."

Session 1: Protecting Infrastructure and Reuse Reliability: Integrated Adaptive Plan for Odor, Corrosion, and UVT

The City of Modesto operates a 20 MGD two-plant treatment system, with primary treatment at the Sutter Plant and secondary/tertiary treatment at the Jennings Plant. In recent years, the City has faced escalating odor complaints near Sutter, severe hydrogen sulfide (H₂S)-driven corrosion at Jennings, and seasonal ultraviolet transmittance (UVT) drops that jeopardize recycled water compliance. This study integrated field investigations, bench testing, and technology evaluations to develop an adaptive, tiered plan addressing all three challenges concurrently.

Comprehensive monitoring in four major trunk sewers and both plants quantified sulfide mass loads, confirmed two major trunks as dominant contributors (>80% of load to Sutter), and documented extreme H₂S levels at Jennings—averaging over 100 ppm and peaking above 700 ppm at fine screens. UVT declines were found to coincide with seasonal blending of high-BOD, low-pH cannery wastewater with domestic flows, introducing lignins, tannins, and potentially UV-absorbing artificial sweeteners. LC-MS confirmed the presence of five sweeteners in UV influent, though their individual impacts remain to be quantified.
A broad suite of odor/corrosion control options was screened against technical, operational, cost, and UVT-risk criteria. Chemicals with potential toxic by-products or proven UVT impairment were eliminated. Life-cycle analysis showed pure oxygen injection to be 3–6x less costly than chemical dosing for major trunk applications, with nanobubble oxygenation offering potential dual benefits for odor suppression and UVT improvement.

Bench-scale ECO₂ oxygenation tests validated rapid, complete dissolved sulfide removal within 30 minutes and confirmed low oxygen uptake rates, supporting conservative system sizing. The recommended adaptive plan applies a tiered approach: (1) immediate oxygen injection installation at Woodland and Thousand Oaks lift stations; (2) Sutter biofilter optimization, and nanobubble pilot testing; (3) targeted force main treatment via nanobubbles, oxygen injection, or nitrate dosing; and (4) end-of-line H₂S capture at Jennings via biotrickling filters.

Parallel UVT mitigation tiers included reverse blending to isolate cannery flows, nanobubble piloting, targeted compound source characterization, and long-term industrial source control via pretreatment or sewer-use by-laws. This integrated, data-driven strategy enables Modesto to phase investments, respond adaptively to performance data, and meet both odor/corrosion and recycled water reliability goals within operational and financial constraints.

Learning Objectives:
After the presentation, participants will be able to diagnose odor, corrosion, and UVT challenges using field data and source identification techniques
After the presentation, participants will be able to compare the cost, performance, and UVT impacts of chemical, oxygen, and nanobubble treatment strategies
After the presentation, participants will be able to apply a tiered, integrated and adaptive planning framework to phase solutions that protect infrastructure and protect recycled water reliability"

Session 2: From Failing Septic Systems to Sustainable Futures: Sewer Solutions for Disadvantaged Communities in Sacramento County

A new tool is available for concrete cylinder force main condition assessment: electromagnetic (EM) thickness testing. This tool does not require destructive methods that increase risk and defeat the purpose of assessment, nor does it require deployment of equipment on the inside of the pipe. V&A is piloting a technique developed in the oil and gas industry to use an EM probe on the outside of the pipe to measure metal thickness. Ross Valley Sanitary District's seven-mile force main system is about 42% reinforced concrete cylinder pipe (RCCP), with a steel cylinder surrounded by cement and outside steel reinforcing, installed between 1958 and 1986. RVSD would prefer avoidance of costly replacement if a non-destructive condition assessment technique would indicate more years of remaining service. The application of EM testing to a section of RCCP pipe along a known corrosion gradient will be presented, along with costs, equipment, procedures and results, and the potential application of EM testing in RVSD's broader condition assessment program will be discussed.

Learning Objectives:
Understand electromagnetic testing equipment, procedures, and costs, and how they relate to metal thickness of force main assets and their remaining useful life.
Understand how the study of a gradient of defective pipe, using corroded section of bypass force main, demonstrated the usefulness and sensitivity of EM testing to measure metal pipe thickness.
Evaluate whether to invest in electromagnetic testing as a targeted condition assessment tool and compare it with other force main condition assessment techniques and force main management approaches."

Session 3: A New Tool for Concrete Cylinder Force Main Condition Assessment - External Electromagnetic Thickness Testing

The Sacramento Area Sewer District (SacSewer) spearheaded a critical infrastructure project to replace failing septic systems with public sewer service in five small, disadvantaged communities in Sacramento County. Many of the replaced septic systems were beyond their useful lifespan, unpermitted, or unable to meet modern regulatory standards, posing risks to public health and the environment. The project constructed approximately 51,660 linear feet of new sanitary sewer pipelines, enabling households to abandon outdated septic systems and connect to reliable public sewer service.

Given the financial hardships faced by these low-income communities, SacSewer successfully pursued local, state, and federal grant funding and other cost-sharing assistance to make sewer conversion available at no cost to the residential and school properties in these communities. This effort required extensive community engagement and education with the goal of residents and property owners understanding that converting to sewer service would not only alleviate septic system maintenance burdens and avoid increasingly stringent septic regulations, but also protect groundwater, bolster public health, and enhance their property values. SacSewer expects construction to conclude by the end of 2025 with successful implementation ensuring long-term environmental protection and equitable access to essential wastewater services in Sacramento County.
Presenters will share lessons learned in securing and coordinating funding, managing project schedules, and designing effective community engagement strategies.
Key takeaways will include:
• How to approach and structure successful funding applications and coordinate with multiple funding agencies
• Strategies for building property owner trust and participation
• Critical lessons from construction document requirements and permitting
• Team collaboration practices between owners, SacSewer, funding agencies, and design and funding consultants that improved project delivery
The session will be interactive, using tools such as Mentimeter to engage the audience through live polls and Q&A. Attendees will leave with both immediate, actionable strategies for their own projects and broader lessons for sustaining long-term infrastructure improvements in underserved communities.
Learning Objectives:
Upon completion, participants will understand and know how to approach and structure successful funding applications and coordinate with multiple funding agencies.
Upon completion, participants will know strategies for building property owner trust and participation.
Upon completion, participants will know lessons from construction document requirements and permitting as well as team collaboration practices between homeowners, SacSewer, funding agencies, and consultants that improved project delivery."

The water industry is experiencing a transformative shift driven by the convergence of digital technologies and data science. Among these, artificial intelligence (AI) is emerging as a powerful and disruptive technology to address challenges in water resource management, infrastructure optimization, and operations. AI models' ability to learn from and predict patterns directly from data, examples, and experience, rather than relying on mechanisms or pre-defined rules, makes this technology highly applicable to the water industry.

Machine learning (ML) is a subset of AI that enables systems to learn from data and improve performance over time without explicit programming. ML sits within the broader AI landscape and is particularly relevant for water applications due to its ability to handle structured and unstructured data, adapt to changing conditions, and uncover hidden insights. In water management, ML can be leveraged to predict equipment failures, optimize treatment processes, forecast influent flows, and enhance decision-making.

This presentation explores the evolving role of ML in the water sector, demystifies core concepts, and illustrates their application through real-world case studies. It also highlights the critical importance of data quality, system integration, and human factors for successful deployment. The presentation emphasizes that while ML may appear complex, it is fundamentally rooted in mathematical relationships and pattern recognition—making it accessible and highly valuable when applied correctly.

The presentation will provide a practical assessment of the ML algorithms gaining utility in the water industry and discuss the data requirements and challenges when implementing ML technologies.
