Tell us about what inspired you to join the industry.

Right out of high school, I worked for several construction companies on large commercial and institutional projects. I would observe the engineer or architect come to the site to check on their design and on the work we were doing. To have the responsibility and freedom to take a design from concept to reality really intrigued me and led me to consulting engineering.

What is your favorite ArchTam project that you’ve worked on and why?

I want to say most of my projects hold special meaning. However, my favourite project is probably the Saskatchewan Landing Regional Water Project (SLRWPU) where I was the project manager and project engineer. This project brought a reliable and sustainable potable water system to a vast area of west-central Saskatchewan.

The project was with one of our longest-standing clients in the Town of Rosetown — a partnership that made us truly excited to pursue this work. I still remember meeting with the water utility in its earliest days, before they had even issued an engineering request for proposals, and being part of the journey all the way through to celebrating the 10-year anniversary of the project’s completion.

Over seven years, we delivered a transformative solution: two water treatment plants, five booster stations and reservoirs, and 700 kilometers (435 miles) of transmission and distribution pipeline. The impact on the community was profound and lasting. We’re incredibly proud to have helped SLRWPU achieve its vision and complete a project that continues to make a tangible difference in people’s lives.

Tell us a story of how your work positively impacted the community.

Growing up and seeing the effects of untreated water on public health and safety motivated me to become a water and wastewater engineer. I carried that motivation into my education, earning a bachelor’s degree in chemical engineering and then a master’s degree in environmental engineering, where I focused specifically on water and wastewater treatment. That path shaped my entire career and continues to drive my commitment to preserving water resources for all.

What is your favorite ArchTam project that you’ve worked on and why?

My favorite project is the 360-million-gallon-per-day (MGD) City of Houston East Water Purification Plant. It was the first project I was assigned to when I joined ArchTam and I’ve been involved in various aspects of its design and improvements ever since.

The project began with a Sustainability Evaluation Study to assess and recommend strategies for long-term plant sustainability. Over more than a decade, it has evolved into a series of impactful improvements that have strengthened the facility and its operations. Throughout this time, I have built strong relationships with the operations and maintenance staff, and the engineering team — everyone who keeps it running. Being responsive and accountable to the client has been key, and it’s rewarding to know that our work is helping Houstonians access safe, clean drinking water.

When Hurricane Harvey hit Houston, our team’s foresight and preparation ensured the East Water Purification Plant stayed operational, keeping safe water flowing to millions despite record-breaking rainfall. Planning ahead for vulnerabilities and implementing critical improvements made all the difference. Most recently, we completed a condition assessment of the plant facilities and developed a facility master plan to address deficiencies and create a blueprint for future capacity expansion. A recommendation was made to decommission Plants 1 and 2 to make way for a more resilient treatment facility. This recommendation will provide long-term reliability and redundancy with a focus on producing clean and safe drinking water sustainably.

I’m working on three different projects for the City of Port Lavaca, a historically underserved community. One of the key initiatives involves expanding their wastewater treatment plant, significantly improving infrastructure to support future growth and environmental resilience. The challenge was that they didn’t have the financial capability to fund the expansion.

We explored different grant options, but they didn’t qualify for any at the time. After extensive research into alternatives, we were able to secure a loan for them through the Texas Water Development Board. We applied on their behalf and successfully obtained funding, which will reduce impact and help the city and its residents move forward.

It felt rewarding to be involved from the very beginning, helping build the project all the way through and truly making a difference for the community.

During my gap year before university, I worked for a grassroots environmental group in Massachusetts as a community organizer and door-to-door fundraiser. Our leading issue was advocating and organizing for the clean-up of groundwater pollution from a neighboring military base. I saw firsthand both the environmental effects and the bureaucratic challenges in addressing complex and sensitive issues. But more importantly, working with local residents and public officials showed me the vital and effective role that informed public engagement, stakeholder commitment and collaboration can contribute to achieving effective environmental solutions. This formative experience encouraged me to earn a master’s degree in public policy from Harvard University’s Kennedy School of Government where I gained the analytical skills and tools I needed for a career as an environmental economics practitioner.

What is your favorite ArchTam project that you’ve worked on and why?

Over the last 14 years, I have been involved in planning and development of Sites Reservoir in Northern California. Once completed, it will be California’s largest new reservoir project in over 50 years and will provide off-stream storage of up to 1.5 million acre-feet of water — enough to serve 7.5 million people. The project is an ambitious and expensive collaboration between the U.S. Bureau of Reclamation, the State of California, and more than 20 regional water agencies. It has been an interesting, challenging and personally rewarding experience supporting the project’s evolution from initial conceptual alternatives to its forthcoming project delivery during a period of shifting political contexts, regulatory requirements and evolving future water demand and availability projections.

As a complex and multi-benefit water project, there is a multitude of interrelated resource and operational issues. Determining the project’s lifecycle costs and benefits has been an important component of the work. My work also included the analysis to identify the most beneficial approach to water management for urban water demand, agricultural, ecosystem, recreation, flood protection, water quality, emergency supply and hydropower generation. My analysis has supported the evaluation and selection of project alternatives, justified over US$1 billion in federal and state funding, and assisted sensitive negotiations between agency partners to secure public benefits. As a result, this project has greatly expanded both my understanding and ability to perform comprehensive and rigorous economic feasibility evaluations.   

One of the most rewarding achievements was helping the Sites Authority apply and advocate for state funding. This effort required intensive collaboration with the team’s hydrologists, engineers, cost estimators and environmental experts to quantify and document the reservoir’s expected long-term performance.

As a member of our Process Mechanical and Pumping Systems Technical Practice Group, Tom oversees standards, master specifications, and the design of mechanical process systems, materials handling, and chemical storage and feed systems.

In this Deep Dive, we are highlighting how Tom and his team enhanced the reliability of New York City’s sewer infrastructure by rehabilitating the Avenue U Pumping Station, while implementing innovative strategies to ensure uninterrupted operations during the upgrade.

In urban environments, rehabilitating critical infrastructure like pumping stations presents a unique set of challenges, especially when continuous operation is non-negotiable. The Avenue U Pumping Station rehabilitation project in Brooklyn, New York City (NYC), exemplifies innovative engineering solutions to these challenges. The pumping station serves the community by collecting and pumping wastewater from the surrounding area to the treatment facility, preventing flooding and ensuring the safe and reliable conveyance of sewage. It plays a critical role in protecting public health and maintaining environmental standards in Brooklyn.

Serving the community for decades, the station faced aging equipment, structural vulnerabilities and limited operational flexibility. The challenge, therefore, was to modernize the station while keeping it fully operational throughout the construction process. The project is not only addressing immediate infrastructure needs but also serves as a model for future rehabilitation efforts. As cities worldwide grapple with aging infrastructure, the lessons from Avenue U will guide engineers and policymakers in maintaining essential services during complex upgrades.

The primary challenge was designing a rehabilitation plan for the pumping station that would allow it to remain fully operational throughout the construction process. This required developing a comprehensive bypass pumping system capable of handling the station’s full capacity without interrupting service. The complexity of working in a dense urban environment, with limited space and strict regulatory requirements, added another layer of difficulty.

As the design manager, I played a central role in coordinating with the client, contractors, and other stakeholders to develop an innovative bypass system that is both constructible and resilient. My responsibilities included managing the design team, ensuring seamless communication across disciplines, and aligning our approach with the client’s goals and regulatory requirements. We conducted detailed hydraulic modeling and risk assessments to ensure the system could handle peak flows and unexpected scenarios. One key innovation was incorporating an interconnecting pipe between two influent manholes at the pumping station, replicating existing conditions and enhancing system flexibility.

A memorable breakthrough moment came when we finalized the design of the bypass system, ensuring it met all operational and regulatory requirements. This was a testament to the team’s meticulous planning, collaboration and leadership. My role involved not only bringing unique ideas to the table, such as optimizing the layout of the bypass system to minimize space requirements but also ensuring that these ideas were executed effectively through close coordination with all parties involved.

Leigh Martin is a seasoned professional with extensive experience in the water sector. He started his career with ArchTam in London and later moved back to his hometown of Melbourne. His roles have spanned technical, project management, people management and business development. As a lead verifier and project manager, Leigh has been involved in several high-profile water projects, demonstrating his commitment to technical excellence and innovative solutions. 

Tell us about what inspired you to join the industry. 

I must have been a slow learner, as it took me a while to realize the career path I wanted to pursue. Reading a glossy aeroplane brochure as a wide-eyed high school student inspired me to study aerospace and mechanical engineering, but I soon discovered that the types of aerospace jobs in Australia weren’t going to get me out of bed in the morning. I worked in this industry for several years before stepping back to reflect on my career and asking myself honest questions about the work I was doing and the legacy I hoped to leave behind. 

At this point, I was living in London and work was just starting on the Thames Tideway, a huge 25-kilometer sewer tunnel built under the River Thames, right through the heart of the city. It wasn’t long before the project had me hooked. Where else could you collaborate with global specialists to build massive underground structures in the center of a major city, whilst making a positive impact on the environment? 

The Thames Tideway project, for which I was the lead mechanical engineer, inspired me to join the water industry. I’m constantly reminded that I’m in the right place by the projects that I work on and the people I work with every day. I’ve enjoyed roles spanning technical, project and people management, and business development. I am now back in Melbourne working flexibly in my role while spending quality time with my two very energetic and active children. My colleagues have provided outstanding support and flexibility every step of the way. 

What is your favorite ArchTam project that you’ve worked on and why?

Whilst the aforementioned Thames Tideway project was fantastic, it’s hard to look past the work that the local water team recently delivered at Melbourne Water’s Upper Yarra Reservoir. Upper Yarra is a beautiful reservoir in the foothills east of Melbourne, a stunning part of the world. I was raised in the valley across from the reservoir, so it’s always been a very special place for me. 

We are working on several active engagements at Upper Yarra Reservoir; I was involved as the lead mechanical engineer for the five-yearly comprehensive inspection of the site. The aim of the comprehensive inspection is to review the asset condition, configuration and consequence category per Australian National Committee on Large Dams (ANCOLD) guidelines. The inspection of Upper Yarra involved performance testing of several large outlet valves, each of which provide critical isolation functions for Melbourne’s primary water supply. Planning and then delivering this testing program, which included closing valves into 600-megaliter per day flow, was rewarding from a technical standpoint, as it successfully demonstrated the integrity of the dam outlet works as well as their capacity for future maintenance, upgrades and managing downstream releases. The testing involved wide stakeholder consultation, including careful ramping and measurement of flows to the local Yarra River to manage the impact on the local environment.

Overall, the extent of testing has raised the asset management benchmark for our other local water clients. We subsequently worked with Melbourne Water to publish a paper on our approach, which was presented at the 2023 ANCOLD Conference in Cairns, Queensland.

One of my favourite things about the water industry is that you can pick virtually any project and have a great answer to this question. Personally, a significant project I worked on was as package lead for the Prospect Pump Station upgrade, which was part of the wider Prospect to Macarthur Distribution Link program for Sydney Water. 

This was a vast upgrade of Sydney’s water infrastructure, linking their main storages and improving drought resilience for large parts of the city. The project evolved to facilitate the growth of key Sydney suburbs, providing significant improvements to the security of Sydney’s water supply. Our team delivered complex technical solutions to create a design compatible with existing brownfields infrastructure, including bespoke mechanical, structural and electrical arrangements — examples of which include hot-tapping into an existing 1700-millimeter diameter water main, rebuilding the high voltage distribution network and cutting over power from the existing network without interruption to supply. This multi-discipline project was designed in an integrated 3D environment using laser scanning of infrastructure to inform existing geometry. Delivering the project for the residents of Sydney was an incredibly satisfying outcome for the whole ArchTam team.
