City of Roseville

Dan is a Water Treatment Plant Operator with nearly 18 years of experience. Before his role at the plant, Dan worked in uniform delivery and the grocery business. His decision to pursue a career in water treatment stemmed from his desire to provide for his family while contributing to the community by ensuring access to clean, safe drinking water.

One of Dan’s favorite aspects of his job is the opportunity to work in a beautiful location every day. His responsibilities include making rounds to ensure all systems are functioning correctly, monitoring tank levels to guarantee a sufficient water supply for the community, and regularly testing the water to meet safety and quality standards.

Dan takes pride in knowing his work is essential to the well-being of the community he serves.

Sunny is a water conservation worker for the Environmental Utilities Water Efficiency Division, bringing nearly 15 years of experience in the landscape and irrigation industry to her role. Although she has been with the City for just under two years, her background also includes working as an Equipment Operator for CalTrans for seven years and a few years in Vegetation Management for PG&E.

Sunny’s deep-rooted passion for plants, trees, and gardening led her into the irrigation and water conservation fields. She enjoys helping residents troubleshoot their irrigation systems, discovering unique landscapes and gardens, and connecting with others who share her passion for plants and trees.

On a daily basis, Sunny plays a crucial role in investigating residential water leaks, guiding customers to locate and repair issues, and helping the community save water.

Nik Mandelik is a wastewater utility maintenance worker and has been with Environmental Utilities for six and a half years. He was led to work with the City of Roseville by a friend who convinced him that it was a great environment and city to work for.

Nik enjoys the opportunities to work for different divisions within Environmental Utilities. He is currently working within the recycled water program, which is ever-expanding throughout the city, that keeps our parks and medians green, limiting the use of surface water to irrigate.

One of the highlights of his position is the various opportunities to work alongside other departments. For example, he assisted in the construction of an off-road driving course for the Fire Department, as well as helped them dig a trench for rescue training.

Matt is a water distribution worker for Environmental Utilities and has been working for the department for just over a year, but is not new to the trade, as he has supported other water districts throughout his career.

Originally from Australia, Matt made the move to the U.S. with his wife five years ago. He enjoys fixing things and knowing he plays a role in the successful distribution of water throughout Roseville. Part of his work in involves preventative maintenance on the 5,600 hydrants throughout the city. 

What Matt likes most about working for Roseville's water division is that, while he and the crews get their projects done efficiently, he can still be himself and have fun on the job.

Brett Coleman is an outdoorsy, hands-on type. And hands-on is exactly what he’s been doing for the City of Roseville for 12 years. This father of three is a crew member of the of our water utility, where he is in Preventative Maintenance, checking and rechecking fire hydrants, valves, blow offs, and other essential equipment to make sure they are working and functioning. He gives it his all each day, and says each day, he’s grateful for the opportunity to work for the many customers that call Roseville home or a place where they do business

It’s the culture at work to be the best that he loves. He was hired in his early 20s because he’s mechanical and had experience installing sewer lines and infrastructure from his previous jobs working construction. He definitely had the background to get his foot in the door, and started out working street maintenance. At the time, Brett didn’t know that he would have so much opportunity to learn, train, get certified again and again, and — most importantly — get promoted and secure a future. And, he didn’t know his coworkers collectively would have the work ethic and drive he so admires and emulates each day.

Not only does Brett work for Roseville residents, he is also a dad that loves to hunt and fish with the family and is partial to community involvement that focuses on the kids. He volunteers at the Big Trucks Summer event at the Roseville Utility Exploration Center each year, and never tires of the cheerful children pretending to drive the City’s garbage and fire trucks and really honking the horns.

Brett’s advice to others who are starting out with the City is to have a deep conviction for what you do, work hard, and continue to do your best each day. In other words, as Brett’s supervisors would say, wake up each day and be a Brett.

Jason Marks has been serving the Roseville community as a Senior Engineer for almost five years. What drew him to his line of work was his enjoyment of math, science, and problem-solving -- the perfect formula for an engineer.

But what does a water engineer do for the city? They design distribution systems that ensure the constant flow of water, of course! While engineers are most commonly associated with bridges, roads, buildings, and mechanics, water distribution is more out-of-sight and out-of-mind -- until it is in high demand.

Jason is no stranger to the water industry. He has also played vital roles in other cities' wastewater treatment processes. His well-rounded knowledge and expertise is what helps to keep Roseville's water flowing. 

Spencer has been supporting the residents of Roseville for almost two years and is currently serving as wastewater collections utility maintenance worker. What keeps him motivated during the day is the group of people he works alongside with, as they share the common goal of working hard, providing high quality service, and getting home safely -- all while having a bit of fun.

Spencer is also a long-time resident of Roseville. He was raised in the area and his father dedicated 34 years of his life to the city, so he has seen first-hand what it was like to serve the community. 

A fun fact about Spencer's line of work is that he and his crew help maintain Roseville's sewer system that processes millions of gallons per day between our two wastewater treatment plants!

 

Kristina is a Management Analyst in the Water Division at Environmental Utilities. With five years at the City of Roseville and a decade in the healthcare industry, she’s committed to meaningful work that benefits the community.

Kristina thrives in compliance, ensuring accountability and trust within the team and community. She enjoys collaborating with field crews who work behind the scenes to ensure safe drinking water. Every day, Kristina addresses water quality concerns from residents, making sure issues are investigated, treated, and prevented.

“We don’t take shortcuts, and it shows,” says Kristina, proud of the high standards her team upholds.

Justin is a wastewater treatment plant operator at the Pleasant Grove wastewater treatment plant. Before stepping into this new role, Justin spent 12 years running and managing an auto recycling yard in Rancho Cordova. He enjoyed his work, but he realized that the job was limiting his personal growth and long-term plans.

Now, in his new career, Justin feels more aligned with his future goals. He finds immense value in the support of his coworkers, who have been instrumental in his development as an operator. Each day, he manages the intake of 5-7 high-strength waste (HSW) trucks, ensuring they are unloaded and handled properly. Additionally, he keeps a watchful eye on the equipment and plant, inspecting and maintaining it to ensure smooth operations.

Justin is excited about his future in wastewater operations, knowing he’s found a role where he can grow both personally and professionally.

Nayeli serves the residents of Roseville as an office assistant in the water utility customer service section. She has been in her role for almost a year and enjoys helping customers and providing solutions when they are in need.

One of the biggest perks of the position for Nayeli is that she is able to interact with different people on a daily basis, in and out of the department. From the time she sits down in the morning to assist callers, to the moment she puts down her headset in the evening to go home, she is happy to know she is making a difference in the community. 

Roseville is the kind of place where residents know their neighbors, and their neighbor may be a Roseville Environmental Utilities employee. That is certainly the case for those who live on the same block as Melissa Park, an industrial waste technician for the wastewater utility.

She is a third generation water treatment expert, often talking shop with her grandfather and father when she was just a young girl growing up in Roseville, and even standing side by side with her dad at work may years later.

Now she is measuring microorganisms in wastewater discharged into Dry Creek (bugs are good.) She also measures PH levels and conducts other tests to ensure a clean water environment. Her job requires a lot of environmental science — perfect for someone who rallied her Roseville neighbors to recycle when she was in the sixth grade, and in junior high, interviewed Kim Spear on wastewater, the same Kim Spear who was Melissa’s boss until Kim retired several years ago.

Melissa wants everyone to know that the water treatment facility where she works is providing clean water to our creeks, just what is needed to keep them flowing fresh, especially in the stagnating summer.

Melissa is a natural communicator, an educator and the enforcer when it comes to insisting on good habits for the betterment of the environment. She says small changes make a big impact, so start by taking the store stickers off your apples. They clog the equipment at the water treatment facility. Who knew?

Roger Schermerhorn has been in the business of serving the residents of Roseville as a Water Distribution Worker for five years. His past experience with plumbing and pipefitting made for an easy transition into utility work, especially for a growing city. As an employee and a resident of Roseville, Roger takes pride in his work.

What keeps the work interesting for Roger is the dynamic of Roseville's water resources. While most communities rely on surface water, the city also utilizes a large portion of its water through groundwater wells -- both of which Roger helps to flow freely through the use of multiple distribution systems.

Michelle Sullivan is a landscape business owner turned Roseville Environmental Utilities water conservation worker. As a former landscaper, Michelle wishes she knew then what she knows now about efficient water choices. Now that she is a water efficiency expert for other businesses, she can let her real passions fly — advocate for efficient water use and help residents lower their consumption —closing the public knowledge gap with customers about best practices on using water as wisely as possible.

Starting a water conservation career at the height of the last drought has had a lingering impact on Michelle’s personal and professional life. She challenges her own water usage as diligently as she does her neighbors, and is always in search of the next new water saving device or technique. She understands that people are not inherently wasteful, and she simply wants to help.

Michelle believes in investigating high water usage for leaks rather than assuming the customer is a high-water user, and trusts that with education and water-saving tools, everyone can be a water saver. Her greatest source of pride comes from making community connections, building trust, and sharing water conservation techniques.

Always happiest in the field, Michelle helps residents identify leaks to prevent property damage, and walks residents and businesses through the process of inspection and conservation methods. If they become water efficient believers too and realize every drop counts, then Michelle has had a great day.

Anthony is a dedicated Water Distribution Worker with over four years of hands-on experience in the field. Before transitioning to this path, Anthony worked as a flooring installer and warehouseman, but his interest in the water industry was inspired by his father, father-in-law, and brother-in-law, who all work in water distribution. Anthony found the profession interesting and a solid career choice.

What Anthony enjoys most about his role is the camaraderie he shares with his coworkers, many of whom are his friends. He takes immense pride in making critical repairs and ensuring the smooth operation of the water system, knowing that his efforts directly impact the community's access to clean, reliable water.

On any given day, you’ll find him operating groundwater wells and carefully monitoring system pressures to keep everything running smoothly.

David Boisa is a staple in Environmental Utilities' Water Division. He is a water distribution supervisor that has been with the department for 20 years. He started his career in the warehouse and quickly moved his way up into water distribution, taking great pride in his work.

Boisa has lived in Roseville his entire life, so serving the community he lives in is fulfilling. He enjoys being in touch with the customers who are experiencing trouble with their service so he can assist them with solutions to help them resolve any issues.

He and his team are responsible for the maintenance and installation of over 50,000 water meters throughout Roseville. There are 50-75 new installations each week, keeping them well occupied in our continuously growing city.

Frank Dittrich began his position as an industrial waste specialist for Environmental Utilities' Wastewater Division in 2021, but has been in his field for over five years.

Frank enjoys the work he does with the city, as he is also a resident, so he is able to visit sites that he wouldn't normally pay much notice to. His interaction with utility customers and the opportunities to engage with and educate them on proper handling of industrial waste is one of the many aspects of his job that he appreciates.

What is dynamic about Frank's position is that he does not operate solely within Roseville's city limits. As an industrial waste specialist, he is tied to the regional sewer shed, so all of the pipes that are connected to Roseville's treatment plants are within his area of responsibility, ranging from Granite Bay, Lincoln, and Newcastle. 

Loni Randolph is a materials technician for Environmental Utilities' Wastewater Collections Division. She began working for Roseville in a part-time capacity over five years ago, but made the full-time move to her current department in 2020. 

She enjoys many aspects of her job, including supplying the teams out in the field with the necessary equipment and tools to complete their work, but it's the people she works with that make her workplace enjoyable. She is happy to be a part of a team, or what she describes as a "small family," that gets things done for the residents of Roseville.

Since he was a kid, Roseville Environmental Utilities plant and equipment mechanic Dave Eulberg has always liked to tinker. And, as he grew older, he gravitated toward welding and industrial fabrication while working in machine shops. Now, Dave is tinkering with the pumps and machinery at Environmental Utilities to guarantee clean and clear water is splashing out of those Roseville faucets.

Each day, Dave looks forward to the camaraderie he enjoys with his “family” at work as he monitors the pumps, fixes and repairs the gear boxes, and when necessary, takes a piece of steel and retrofits it to just the right specs (better than factory made!) to keep the plant humming. He takes pride knowing that his hard work is ensuring the water coming from Folsom Lake and journeying through the Barton Road Water Treatment Plant, becomes clean water for the citizens of Roseville.

The Roseville community is where Dave is raising his young family, and instilling the same discipline and caring he practices at work. At Environmental Utilities, he lives by the simple virtues of hard work, being clean and tidy, properly storing tools, helping others and exercising safe practices. At home, those qualities translate into a structured environment, where his children do their homework before play, and learning everyday is the expectation.

Dave is also constantly improving his own skills through education. He finds time to take electrical theory and computer building classes at Sierra College, and never shies away from acquiring job-related certificates for professional development. Dave will say he’s a process guy, and a safety-first guy, who sets out to do a good job at every task he’s preforming. And at end of each work day, he hustles home to check his two daughters’ homework before announcing it’s time for play.

Nelson Santos has been a water distribution worker for 13 years. Yet, he is still in awe of the massive, behind-the-scenes effort it takes to make turning a faucet on and enjoying clean running water such a routine event. He finds the potable and recycled water delivery process fascinating, and the opportunity to learn more about it on the job, rewarding.

After a short career out of high school working maintenance for a school district, Santos, a young dad with a growing family, needed a job that provided growth and benefits. He found it at Environmental Utilities, working among a crew that maintains the underground water mains, installs service lines to meters of new homes and businesses, conducts maintenance and handles repairs, especially emergency ones.

Santos takes pride in the City’s 24/7 response to service calls, even if it means on-call duty for him one week a month. If a water main breaks or a car hits a hydrant in the middle of the night, Nelson likes to say, residents will still be able to brush their teeth in the morning. Even in the middle of the night, according to Santos, Roseville neighbors are appreciative of their efforts, often offering lemonade or coffee, and are genuinely kind.

After work, Santos goes to his other job, escorting his kids to their sports activities. When he has time, Santos rides dirt bikes, and likes to go to the coast and be with family. He likes working for a company that goes beyond providing the minimum requirements for clean, safe water, and likes the security of working for the City. You won’t make a million dollars, he says, but there is always room to grow.

Chad Brown is a wastewater treatment plant operator for Roseville and has been serving our community for almost two decades. He has been a resident of the city as well as a vital part of the successful operation of the Dry Creek Waste Water Treatment Plant.

One of the many aspects of Chad's work that keeps him motivated is the positive impact he makes on the surrounding environment. His contribution helps keep our community healthy and public parks green, ensuring Roseville remains one of the best places to live in California.
