WSO’s history demonstrates expertise and dedication. In fact, water loss management is the sole focus of WSO’s services. WSO’s water loss pre-eminence has been recognized by many industry stakeholders, ranging from the California Department of Water Resources to the Water Research Foundation to numerous water utility managers throughout the country. The drinking water community trusts WSO to define best practices, implement proven interventions against water loss, and pioneer new methodologies. 1 - Firm Background 1.1 Defining Best Practices Research institutes and professional drinking water associations overwhelmingly select WSO to review industry standards, evaluate the integration of new technologies with water loss management, and propose cutting-edge analysis and field studies that support distribution system efficiency. As an endorsement of WSO’s expertise, WSO was chosen to be the lead firm on most Water Research Foundation water loss control studies, including: • Leakage Management Technologies (project 2928) • Evaluating Water Loss and Planning Loss Reduction Strategies (project 2811) • Real Loss Component Analysis: A Tool for Economic Water Loss Control (project 4372A) • Establishing Water Utility Guidance and Methodology for Water Audit Validation (project 4639) • Level 1 Water Audit Validation Guidance Manual 2nd Edition (project 5057) WSO’s Water Research Foundation publications have been recognized as definitive guides to water loss management. Notably, the American Water Works Association recommends that utilities employ WSO’s Real Loss Component Analysis model when developing water loss control programs, and the California Department of Water Resources requires annual water audit validations to follow the methodology presented in project 4639. 2 – Proposal – City of Bozeman, Water Distribution System Audit 1.2 Planning & Implementing Interventions Against Water Loss WSO has worked with more than 60 utilities nationwide to compile and validate detailed water audits. With most of these partners, WSO has moved beyond water loss analysis to establish water loss control programs that save water and money. WSO is particularly proud to have spearheaded the following projects: Los Angeles Department of Water and Power (LADWP) Full water loss control program development and facilitation of the award-winning Water Loss Task Force committee. In each project, WSO established a nuanced understanding of each system’s unique water loss profile, an appreciation for the strengths and uncertainties of each utility’s data sources, and customized action plans that concretely improve system management and financial viability. In addition to developing comprehensive water loss control strategies, WSO has experience with implementing these strategies to reduce water loss. San Antonio Water System (SAWS) Full water loss control program offerings and continued technical assistance with implementation of water loss recovery and data improvements. City of Phoenix Detailed AWWA water audit, component analysis of real and apparent losses, recommendation of data management improvements, and water loss control recommendations. City of Sacramento District metered area installation and management. City of Santa Cruz Full water loss control program offerings, source meter testing procedure development, and continuous technical assistance for over four years. Nashville Metro Water Services (MWS) Leak Detection Survey Services WSO has been selected by Nashville MWS for 3 consecutive 5-year contracts to perform leak detection on their 3,000 miles water distribution system and perform temporary District Metered Areas (DMAs) to assist with leakage estimates and work prioritization. Under the current contract (2015 – 2020), WSO has surveyed over 11,000 miles of main and located an estimated 12,500 gpm of leakage. Guam Waterworks Authority (GWA) Full water loss control strategy development including establishing three pilot district metered areas where non-revenue water was reduced by about 40% on average. 3 – Proposal – City of Bozeman, Water Distribution System Audit 1.3 Pioneering New Methodologies WSO frequently works with water utilities and their stakeholders to improve water distribution efficiency. Recently, WSO was selected to pioneer ground breaking water loss control programs, such as: California Water Loss Technical Assistance Program (Water Loss TAP) WSO was hired by the California-Nevada Section of the American Water Works Association to lead the largest water audit training and validation program ever offered. Through the Water Loss TAP, WSO taught best-practice methods to and level 1 validated the water audits of all 450 retail urban water suppliers in California, as required by Senate Bill 555. Hawaii Water Audit Validation Effort (WAVE) The Commission on Water Resource Management (CWRM) of Hawaii hired WSO in 2016 to implement a water audit training and validation program for compliance with Act 169. In the WAVE, WSO works with four county water agencies that each operate numerous discrete water systems and all large capacity private water systems, and systems located withing Water Management Areas (WMAs) on the Hawaiian Islands. California Energy Utility Partnerships WSO led pilot programs (with Southern California Edison, San Diego Gas & Electric, and Southern California Gas Company) that quantified energy savings embedded in leakage recovery. WSO has since been recruited to advise ongoing discussions about energy efficiency as it relates to water loss control. NRWManager WSO developed a web-based holistic Non-Revenue Water (NRW) and Water Network management application with full integration of all water utility data such as network flow, network pressure, water level in reservoirs, water quality parameters, customer billing data and GIS layers. The solution provides instant access to all data, anywhere, anytime, on desktop PCs, laptops, tablets and smart-phones. It also provides automated intelligent reporting of NRW levels and other Key Performance Indicators (KPIs). 4 – Proposal – City of Bozeman, Water Distribution System Audit 1.4 Galvanizing Regional Cooperation Water loss management is most effective when neighboring agencies and stakeholders act in concert toward a shared goal. However, regional water loss collaboration was not often explored to meet efficiency standards while harnessing economies of scale and managing shared assets. To promote budding regional efforts, WSO has coordinated regional water loss control programs by providing educational seminars, technical assistance, and evaluation and standard-setting. WSO’s recent regional programs include: Municipal Water District of Orange County (MWDOC) Water Loss Control Work Group WSO and MWDOC have partnered to offer a five-year water loss control program to MWDOC’s 31 member agencies. WSO and MWDOC member agencies are evaluating water losses, confirming analytic results with field investigation, designing customized water loss control strategies, and implementing cost-justified interventions. Through the program, Orange County agencies are building an ambitious regional culture of efficiency. Furthermore, WSO and the MWDOC group have produced a ground-breaking customer meter test dataset and established case studies for water loss monitoring and regulation in California. Over the last year, WSO supported MWDOC in the development of a regional water loss control department that offers water audit validation, customer meter testing, leak detection, and field pressure logging to its member agencies. California Water Service Water Loss Program WSO and California Water Service have partnered to streamline the company’s water loss understanding and water loss reduction strategy. WSO’s water loss recommendations will contribute to California Water Service’s goal of preparing its 25 districts for SB555 compliance and the implementation of Executive Order B-37-16. 5 – Proposal – City of Bozeman, Water Distribution System Audit 1.5 Leading the Conversation WSO guides the drinking water industry toward informed water loss management by working with a host of involved agencies and professionals, from distribution system operators to state regulatory agencies. Through outreach, professional service, and water loss control projects across the United States, WSO has: Taught 2,000+ Drinking water professionals about best-practice water loss analysis and water loss control methodology. Advised state regulatory and water management agencies in 9 States, plus Puerto Rico, Guam, and the national and regional offices of the Environmental Protection Agency. Developed in-depth, multi-year water loss control programs for 65 Water Agencies Conducted 1,000+ Level 1 Validations 6 – Proposal – City of Bozeman, Water Distribution System Audit The Request for Proposals (RFP) details five tasks and several key deliverables expected from the Water Distribution System Audit work. WSO summarizes these tasks – alongside their associated goals and outcomes below. Across all tasks, three core themes will guide WSO’s proposed work: 2 - Project Overview 1. Cost-Effective Recommendations WSO has completed thorough economic analysis and developed real and apparent loss recovery plans for more than 60 water agencies nationwide. Wisely allocating resources across diverse recovery projects requires WSO’s appreciation for the costs, benefits, and uncertainties associated with each potential investment. 2. Balancing Stakeholder Interests WSO has experience working with a wide range of water agencies on water loss control strategy efforts. We appreciate the importance of clear communication across diverse internal stakeholder groups. Developing a water loss control strategy is a technical pursuit, but we acknowledge that it is also an opportunity to unify the organization across a set of common goals and ensure that the plan is ultimately implemented. 3. Well-Documented & Repeatable Processes WSO prides itself on our clear communication of findings. We will convey our analysis and recommendations in approachable and thorough documentation. We aim for our reporting to serve as a tool for enhancing internal water loss expertise as well. Water loss assessments are often most valuable when repeated so that trends and patterns can surface. WSO aims to produce reporting and tools that wilk teach agency staff how to carry forward the work. For more detail on our approach, see Section 3 of this proposal, where WSO describes how it would tackle the successful delivery of each of these tasks and outcomes. 7 – Proposal – City of Bozeman, Water Distribution System Audit Each section below describes how WSO will tackle the successful delivery of each of task. Sub-task descriptions detail the work that will meet or exceed the RFP requests. Wherever relevant, WSO’s direct experience and industry leadership is highlighted. Note that all work is anticipated to occur remotely, via conference call considering the ongoing challenges posed by COVID-19. WSO will gladly entertain conversations and weigh decisions around business travel to conduct in-person meetings after WSO participants and City staff agree upon necessary precautions. 3 - Project Approach TASK 0: PROJECT MANAGEMENT WSO will reserve time for regular check-in calls and progress reports to guarantee diligent progress on this project. Regular communication will be a key part of WSO’s strategy in staying on timeline and within budget. Subtasks 0.1 Check In Calls WSO will lead regular check in call, providing agendas and follow up communications as necessary. The frequency of these calls will be scoped with the project team, depending on availability. 0.2 Progress Reports on Invoices WSO will document progress on each task in our monthly invoices. TASK 1: REVIEW OF CURRENT WATER LOSS PREVENTION APPROACH WSO will be sure to study all water loss related activities pursued by the City to date. In this task, WSO will request and review related reporting and/or data and conduct conference calls to learn about past water loss work. Subtasks 1.1 Review Past Water Loss Projects & Findings WSO will pour over the City’s past interactions with water loss data and water loss programming. Understanding what has worked – and not worked! – in the past will be key to informing a best-fit strategy for effective water loss control programming going forward. EXAMPLE PROJECTS TO REVIEW • Leak Detection Program Details & Leak Findings • AMI Program Details & Findings • Pipe Replacement Program Details & Progress • 2014 Water Audit Reporting 8 – Proposal – City of Bozeman, Water Distribution System Audit Subtasks (Task 1, Cont’d) 1.2 Conference Calls to Debrief Previous Water Loss Work In addition to the summary reporting and/or data we will review, WSO will conduct brief conference calls to debrief the City staff’s experience with these programs to date. We’re interested in learning about both the outcomes (i.e. leaks found, meters replaced, etc.) and the reflections on the process (i.e. who was involved, whether the process was documented, where improvement potential was identified). TASK 2: WATER AUDIT DATA COLLECTION, ANALYSIS & COMPILATION WSO will compile a water audit in the American Water Works Association (AWWA) Free Water Audit Software. Upon deciding on the appropriate timeframe for the audit period, WSO will request all relevant data, conduct all quality control analysis, follow up regarding data clarifications and/or obstacles, and complete the AWWA Free Water Audit Software. Note: The City and WSO will discuss whether to use the version 5 or newly published version 6 of the AWWA Free Water Audit Software. WSO is equipped to complete either! Subtasks 2.1 Data Requests WSO will develop and distribute a data collection tracking sheet, where all data necessary for the completion of the AWWA water audit software is identified. The tracking sheet will provide examples of data sources used in previous years (if available from background research). To streamline our data requests, this data request will also include the data needs related to Task 4.1. 2.2 Billing Data Analysis WSO will validate billing data provided in a standard format (one row corresponds to one bill), where available, including verification of data integrity using customized R-scripts and pro-rating of billed volumes to reduce lag-time effects. 2.3 Supporting Documentation Preparation As required for level 1 validation, WSO will summarize the inputs for the water audit, capturing the data source, the derivation approach, and any estimation or uncertainty qualifications. 2.4 Data Debriefs In the process of compiling water audit data, WSO will inevitably encounter questions (i.e. needing clarification about the source of the data or observing an anomaly). Periodic conversations with City staff closest to the data collection will be a valuable process in the audit compilation. WSO authored the California Department of Water Resource’s Water Audit Manual that instructs water suppliers on how to best compile a water audit. WSO has team members featured on the development team of the AWWA Water Loss Control Commitee’s Software Subcommittee, responsible for developing and improving the AWWA Water Audit Software. 9 – Proposal – City of Bozeman, Water Distribution System Audit TASK 3: LEVEL 1 VALIDATION WSO will conduct a Level 1 Validation session to verify all the data used in the water audit is appropriate and all the Data Validity Grades are assigned correctly. Subtasks 3.1 Validation Session WSO will schedule and lead an interview with appropriate staff to confirm the inputs and Data Validity Grades in the water audit. 3.2 Validation Documentation WSO will provide documentation that formalizes the findings of the validation session. Note: The analysis in Task 2 goes beyond the scope of Level 1 Validation and guarantees an even more detailed quality control review of the water audit than Level 1 Validation provides. There may be an opportunity to combine Task 2 and 3 to avoid redundant conversations if that is a concern. However, if the City is interested in practicing the workflow of Level 1 Validation (as it stands separately from compilation support), WSO supports keeping this task. WSO authored the Water Research Foundation’s projects that set standards for the methodology of Level 1 Validation. WSO has conducted over 1,000 Level 1 Validations in the past five years. TASK 4: WATER LOSS REMEDIATION & PREVENTION RECOMMENDATIONS In Task 4, WSO will conduct a more detailed examination of leakage in the City’s system and develop recommendations for effective water loss management. Subtasks 4.1 Component Analysis of Real Losses WSO will perform a component analysis of real losses to establish the City’s unique leakage profile and inform targeted and cost- effective leak management strategies. WSO’s component analysis of real losses will entail background leakage modeling using infrastructure and pressure data, quantification of reported leakage using repair records, assessment of unreported leakage proactively discovered through leak detection, and estimation of hidden leakage ongoing in the system. In the process, WSO will also identify and recommend data collection and management improvements that provide more accurate insight into leakage. WSO’s work on this task will provide: • Determination of the City’s component leakage volumes: background, unreported, reported, and hidden leakage • Break frequency analysis and comparison to national datasets • Evaluation of documented leak response times WSO designed the Component Analysis of Real Losses model (Water Research Foundation Project #4372). 10 – Proposal – City of Bozeman, Water Distribution System Audit 4.2 Real Loss Improvement Recommendations Directly informed by the component analysis conducted in Task 4.1, WSO will develop a suite of recommendations for cost-effective leakage recovery investments. Depending on the City’s component analysis results, these recommendations will feature a combination of the following: • Leak repair response improvement • Proactive leak detection frequency adjustment • Proactive pressure management 4.3 Apparent Loss Improvement Recommendations Directly informed by the data collected for the compilation of the water audit, WSO will develop a suite of recommendations for strategic apparent loss assessment and/or recovery work. This may include recommendations regarding the following: • Small meter testing & replacement practices • Large meter testing & replacement practices • Estimation protocols for unauthorized consumption and/or systematic data handling errors WSO has overseen many leakage recovery projects and appreciates what leak detection work looks like in the field. We have leak detection technicians on staff that support agencies who need the field capacity. TASK 5: DETAILED DOCUMENTATION OF METHODOLOGY & PROCESS WSO will document each piece of the water loss investigation and findings for future reference and stakeholder communication. Each report will describe the task’s analysis, synthesize findings, and outline recommended next steps. Given the currently outlined scope of work, WSO would develop the following detailed reports: • Water Audit Compilation Documentation (delivered in conjunction with task 2.3 Supporting Documentation) • Billing Data Analysis – Detailed Report (delivered in conjunction with task 2.2 Billing Data Analysis) • Real Loss Component Analysis Report (delivered in conjunction with task 4.1 Component Analysis of Real Losses) • Water Loss Program Recommendations (delivered in conjunction with tasks 4.2 and 4.3) 11 – Proposal – City of Bozeman, Water Distribution System Audit WSO’s management of this project will center around organized tracking of project progress and regular communication with City staff. The WSO team is a diverse group of professionals fully dedicated to water loss management following AWWA best practices. The proposed team has experience in a wide range of topics including water auditing and validation, leakage component analysis, supply metering and accuracy testing, data collection/field work, large data set management, and cost-benefit analysis. As of this time, the following team would be most involved and directly responsible for the outlined work. 4 - Management Approach Kris Williams Project Manager Kate Gasner Project Director Jessica Jagdeo Data Analyst 12 – Proposal – City of Bozeman, Water Distribution System Audit As WSO’s Vice President, Kate works on water loss and water-energy nexus projects and is fluent in water audit preparation, component analysis of water losses, meter testing, and flow and pressure data analysis.

Recently, Kris implemented the Hawaii Water Audit Validation Effort, a training and technical assistance program to help water utilities compile and submit annual AWWA water audits to the Commission on Water Resource Management. Teaching in a regulatory context has allowed Kris to develop a deep understanding of how the AWWA water audit spreadsheet serves the interests of utilities and regulators for management and planning purposes. To meet the management and planning objectives of his clients, Kris has pioneered the use of programming languages, like Python and R, to analyze sometimes large and unwieldy water loss related data sets. For example, Kris led the effort to analyze all water audits submitted to the California Department of Water Resources during the Water Loss Technical Assistance Program. Portions of this analysis involved developing web applications that allow users to interactively visualize and summarize compiled water audit data. Kris has also developed new approaches to detailed billing data analysis and customer meter test result analysis and test strategy development. In prior roles, Kris managed staff teams to develop, market, and maintain web applications including an enterprise software application for constituent relationship management for Middlebury College and a homegrown web application for Middlebury students to crowdfund their own projects.
