Every thriving community depends on water infrastructure that works — from drinking water and stormwater to wastewater, tunneling, and everything in between. DLZ brings integrated expertise across planning, design, construction, and asset management, combining hydraulic modeling, regulatory knowledge, and green infrastructure solutions to help communities build resilient systems for the long term.
Water infrastructure decisions aren’t made lightly. They affect your budget, your regulators, and the people who depend on these systems every day. DLZ helps municipalities navigate all of it, from regulatory requirements and funding realities to long-term asset management. We bring the multidisciplinary depth that complex water challenges demand, across every system type and every phase of delivery.
Water systems work best when the people designing them understand the full picture. Our approach integrates hydraulic modeling, GIS-based asset management, and nature-based solutions with the practical site civil and trenchless expertise that complex, real-world projects demand. The result is infrastructure that’s resilient, sustainable, and built to serve your community for years to come.
Planning, treatment, distribution, and storage expertise that helps communities navigate growing demands and keep drinking water safe and dependable.
Comprehensive wastewater engineering across the full system lifecycle, from collection and treatment design to system rehabilitation, hydraulic analysis, and long-term performance support.
Comprehensive stormwater planning, modeling, and design — from master planning and green infrastructure to regulatory compliance and urban retrofit solutions.
Underground conveyance solutions for potable water, stormwater, and combined sewer systems — from feasibility and alignment studies through tunnel design, shaft design, and construction support.
Focus on planning, design, and management of systems that provide clean, reliable water and protect communities from flooding and other water related challenges.
Specialized condition assessment and rehabilitation design for aging pipe infrastructure, integrating inspection data, structural analysis, and trenchless methods to extend system life and reduce risk.
Advanced hydrologic and hydraulic analysis for bridges, culverts, storm sewers, detention ponds, tunnels, and open channels, giving communities the data and confidence to size infrastructure right the first time.
Planning, design, and implementation of green infrastructure solutions that reduce stormwater runoff, improve water quality, and support healthier, more resilient communities.

Our water group delivers comprehensive planning, design, and construction services across drinking water, wastewater, stormwater, tunneling, hydraulic modeling, GIS, and site civil development. From water treatment plants and pump stations to distribution networks, flood control, and underground infrastructure, we support communities through every phase of water infrastructure investment.
We combine the resources and technical depth of a national firm with the responsiveness and local knowledge of a regional partner. Long-term client relationships, multidisciplinary expertise, and a genuine commitment to service are what set us apart.
We work with communities of all sizes, from small municipalities of fewer than 1,000 residents to major urban systems serving more than one million people. Regardless of scale, every client receives the same level of expertise and attention.
It’s important to focus on long-term lifecycle cost savings, not just upfront construction costs. Start by prioritizing improvements through data-driven asset management and modeling. Then phase projects to align with available funding, minimize disruption, and leverage state and federal funding opportunities to make it all possible.
Start by implementing asset management programs to track condition, risk, and performance, and use data and GIS to prioritize repairs and replacements. Align capital improvement plans with long-term system needs, and support decision-making with lifecycle cost analysis and risk-based planning.
Integrating GIS, hydraulic modeling, and asset data into unified decision tools allows you to be proactive rather than reactive in system management. It helps identify risks, inefficiencies, and investment priorities. Scenario planning is a smart approach for addressing growth, climate impacts, and funding constraints.
Yes. We use advanced modeling tools to evaluate system capacity, flow conditions, and infrastructure performance — giving clients the data they need to make confident decisions about capital planning and system improvements.
GIS is integrated throughout our water work, helping clients map, manage, and analyze infrastructure assets for better decision-making, system visualization, and long-term capital improvement planning.
Yes. Our stormwater experience spans system design, drainage improvements, watershed studies, and flood mitigation — including solutions that integrate conventional infrastructure with green infrastructure approaches tailored to each community’s needs.
DLZ has extensive experience with tunnel and trenchless projects for water, wastewater, and stormwater systems, including interceptor sewers and underground conveyance infrastructure in complex and constrained environments.
Our site civil services include grading, utility design, stormwater management, permitting, and site development planning — ensuring projects meet regulatory requirements and integrate smoothly with existing infrastructure.
We provide guidance on permitting and compliance across programs including NPDES, CSO/SSO, EGLE, and FEMA, helping you develop practical, implementable solutions aligned with current and emerging requirements. Our teams coordinate with agencies to streamline approvals, reduce risk, and prepare for challenges like PFAS and evolving water quality standards — keeping your projects moving and your community protected.
It’s important to apply multidisciplinary expertise across engineering, GIS, and water resources. We sometimes refer to our approach as Manage, Mitigate, Maintain: manage projects from planning through design and construction, mitigate risks through proven approaches and technical depth, and maintain clear communication with stakeholders throughout delivery.
Start by aligning project scopes with funding program requirements such as SRF and available grants, and bundle or phase projects to improve affordability and constructability. Apply alternative delivery methods where appropriate, and streamline implementation through strong planning and program oversight.
We provide program management and PM/CM services from planning through construction, coordinating multiple projects, stakeholders, and funding sources while maintaining schedule, budget, and quality control across the program.
Yes. Our construction administration, observation, and management services help ensure projects are built according to design intent, on schedule, and within budget.
Reach out through our website or contact a local office or project manager directly to discuss your project needs, scope, and next steps. We’re easy to work with from day one.
