Water/Wastewater

LDG’s staff has in-depth knowledge and experience with a wide variety of alternative project delivery methods including design-build, adapt-build, integrated project design, and public-private partnerships (P3). Our experience with diverse project delivery methods affords LDG the flexibility to employ the best solution to maximize project quality and client value.

At Larson Design Group, we have specialized water/wastewater engineers in-house providing a range of services. Projects include renovations to treatment plants, right-of-way services, pipeline engineering for potable water distribution or wastewater, force main and pump station design, administrative buildings, and more. We also employ licensed plant operators to provide unique design expertise from the operations perspective. This allows us to effectively troubleshoot existing systems as well as support the cut over to a new system, making sure that the start-up is smooth, the new system operates efficiently, and customers continue to receive high quality service.

LDG's cadre of certified construction services staff is dedicated to representing your interests at the construction site. Through a variety of services such as materials testing, schedule coordination, change order management, project documentation, and regular on-site presence to ensure the work is being performed according to the plans, specifications, and verifying invoices for payment, applicable codes, we help to ensure the project is successfully completed on time and within budget. The key to LDG’s success is our commitment to ensuring the right inspectors with the right experience are assigned to each project. Our inspectors understand and are sensitive to the nuances of how water/wastewater projects differ from other construction projects.

LDG’s staff of environmental specialists and scientists are successful because they continually seek to balance the needs of the owner, the community, and the environment by providing environmentally sensitive and sustainable project solutions. We have substantial experience with stream mitigation projects, wetland identification and delineation, threatened and endangered species habitat identification, low impact development (LID), and coordinating with permitting agencies. All of these are critical requirements in securing the environmental clearances needed to move water/wastewater projects forward.

Whether it is evaluating the foundation requirements of a new water storage tank or determining the placement of a new water well, a thorough understanding of a project’s subsurface conditions is critical to the design of practically every project. LDG’s geotechnical staff begins work on each project during the concept stage, and their involvement continues through the design phase into project construction. This approach to geotechnical engineering ensures our staff is intimately familiar with a project, helping us deliver right-sized and cost-effective solutions.

With a wide variety of asset management methods available, LDG believes that a one-size-fits-all approach will often fall short of meeting client expectations. Instead, LDG works with clients to understand their specific capabilities and needs to identify a complete, tailored asset management program. This practice incorporates detailed asset inventories, identification and prioritization of routine maintenance and needed capital improvements, and critical asset analysis and long-range financial planning to maintain system performance. LDG’s subject matter experts develop depreciation models for new and existing systems, determine replacement costs for individual components, and implement GIS-based tools that can help clients to make informed decisions, saving time and money throughout the asset life cycle. Mapping these complex systems and implementing a geographic information system (GIS) allows clients to track problems, look at trends, and locate aging infrastructure or defects in the system. All of this affords municipal authorities the opportunity to track assets, assess infrastructure, and plan for the future. Together, these practices help assure that a utility system remains properly functioning, well maintained, and sustainable over the long term.

Our engineers take an exceedingly thorough approach to evaluating the unique MEP and fire protection engineering requirements associated with each project. Our goal is to design systems that are engineered within the specific context of the project and needs of the facility and staff. This approach can range from ensuring the appropriate level of heating and cooling, providing electrical service supporting current and future operations, and setting up SCADA systems to help remotely monitor processes. Additionally, our LEED® certified professionals evaluate process operations in order to minimize energy needs, increase efficiency, and consider the long-term value for each project.

Permitting and regulatory compliance can be complex. Our experienced, in-house team knows how to work with local jurisdictions and navigate permitting while proactively supporting needs and desires of the local community. Permitting and associated services include:

• State Environmental Permitting
• Regulatory Agency Application Preparation
• U.S. Army Corps of Engineers Permitting Guidance/Support
• Erosion and Sediment Control Plans
• NPDES
• County Agency Coordination
• Regulatory Compliance Strategies and Negotiation

Combining traditional survey with state-of-the-art UAV/drone technology, Larson Design Group offers a range of survey and mapping services to get the right information to clients as quickly and accurately as possible. Our application of 3D laser scanning and terrestrial LiDAR technologies allows our field teams to capture hundreds of thousands of measurements every minute, quickly delivering the highest level of detail in a safer manner.

LDG’s experienced Process Engineering team delivers multi-disciplined design and integration services for complex industrial systems ranging from greenfield builds to retrofit upgrades. Our capabilities encompass utility sizing, process optimization, debottlenecking, systems automation, mechanical/electrical/piping design, instrumentation and controls, structural engineering, and more. We provide scalable, code-compliant process solutions - bringing clarity to complex systems from early feasibility studies through commissioning.

LDG’s structural engineers understand the specialized engineering that supports water and wastewater infrastructure and work toward an optimal balance between technical function and economic impact. We review and consider all of a project’s structural requirements, along with the needs of other engineering disciplines, to develop an integrated structural approach. Whether designing treatment plant facilities, tank foundations, or pump station structures, LDG has the expertise to support the development of new facilities as well as the rehabilitation and analysis of existing infrastructure.
