Engineering Safe, Reliable Water Systems from Source to Tap
Every morning when residents turn on their faucets, they expect clean, safe water instantly. Behind that simple act lies complex infrastructure—treatment plants processing millions of gallons daily, distribution networks spanning hundreds of miles, and monitoring systems confirming quality. Yet water authorities, municipalities, and utilities across the United States face unprecedented challenges. Aging infrastructure demands replacement, emerging contaminants like PFAS require new treatment approaches, lead service lines must be replaced, and evolving regulations strain budgets. RETTEW partners with water authorities and municipalities to navigate this complexity by planning, designing, and delivering drinking water infrastructure that serves communities reliably while meeting regulatory standards.
Our engineers understand the complete water supply cycle, from source identification through treatment, storage, distribution, and asset management. We help clients navigate funding opportunities, secure permits, design cost-effective solutions, and implement projects that deliver safe drinking water. Our experience spans diverse water systems across the Mid-Atlantic from small rural systems to regional authorities, and we know how to leverage state and local loan and grant programs efficiently.
Water System Planning Starts with Comprehensive Assessment
Supplying safe drinking water requires balancing regulatory compliance, infrastructure reliability, rate affordability, and community expectations. This complexity demands more than good intentions; it requires strategic planning rooted in comprehensive assessment.
Water system planning starts with understanding both current conditions and future needs. Source capacity, treatment capabilities, distribution conditions, storage adequacy, regulatory compliance, and financial sustainability all influence your planning decisions. Improvement programs must prioritize projects that address critical needs while positioning systems for long-term success. RETTEW helps you develop strategic plans that comprehensively evaluate infrastructure, identify priorities, and create implementation roadmaps aligning capital investments with available funding. We bring the engineering depth and practical experience needed to deliver solutions that protect public health, meet regulatory requirements, and manage costs responsibly.
The Market Realities Water Providers Face Today
Much of America’s drinking water infrastructure was constructed in the mid-20th century and is now approaching or exceeding its design life. Asset management programs can help you understand infrastructure conditions and prioritize investments. RETTEW conducts infrastructure assessments, develops asset management plans, and designs rehabilitation projects that extend asset life while managing costs.
Water authorities face an accelerating pace of regulatory change. New Safe Drinking Water Act requirements address emerging contaminants, disinfection byproducts, and distribution system integrity. Lead and Copper Rule revisions mandate service line inventories and replacement programs, often requiring significant system upgrades. Together, these create a complex compliance landscape that demands expertise in regulatory interpretation, sampling program development, and infrastructure planning. RETTEW helps you navigate these requirements systematically, from interpreting regulations to planning the infrastructure improvements that guarantee ongoing compliance.
PFAS, 1,4-dioxane, and other emerging contaminants require treatment technologies beyond conventional approaches. RETTEW evaluates advanced treatment alternatives including membrane filtration (low and high pressure), advanced oxidation processes, ozonation, and other technologies, helping authorities select solutions that balance treatment effectiveness, operational complexity, and lifecycle costs. We guide clients from initial bench-scale treatability studies and pilot testing through design and full-scale implementation.
Growing communities need additional water supply capacity. Drought conditions stress existing sources and water quality degradation requires alternative sources or enhanced treatment. Developing new sources involves hydrologic investigations, wellfield design, and complex permitting. RETTEW conducts hydrogeologic studies, designs water supply infrastructure, and develops source water protection programs that enable long-term supply reliability.
Aging distribution infrastructure results in water loss through leaks and breaks, but distribution system improvements demand careful planning and phased implementation. RETTEW designs water main replacements, conducts hydraulic modeling and coordinates distribution system improvements with municipal capital programs.
Water infrastructure requires substantial capital investment, yet rate pressures limit available revenue. Federal infrastructure programs, state revolving loan funds, and other grants provide critical support but require proper documentation and project justification. RETTEW helps authorities identify funding opportunities, prepare funding applications, and structure projects to maximize grant funding while minimizing ratepayer impact.
How RETTEW Supports Drinking Water Systems
Water System Planning and Asset Management — We develop comprehensive plans including capital improvement programs, asset management plans, source water assessments, and strategic planning studies that help authorities prioritize investments, plan for growth, and maintain regulatory compliance.
Treatment Plant Design and Upgrades — RETTEW designs water treatment facilities ranging from small systems to regional complexes. Our experience spans conventional treatment approaches and advanced water treatment (AWT) systems that address emerging contaminants. Whether incorporating membrane filtration, advanced disinfection, oxidation processes, or enhanced nutrient removal, our designs balance treatment effectiveness with operational simplicity and cost-efficiency. We conduct process modeling and pilot testing to optimize technology selection before final design, so systems meet regulatory requirements and perform reliably for decades.
Source Development and Wellfield Design — We conduct hydrogeologic investigations, design water supply wells, develop wellfield protection plans, and design surface water intakes. Our services include aquifer testing, yield analysis, and source water permitting to ensure reliable, sustainable water supplies.
Distribution System Design and Rehabilitation — RETTEW designs water main extensions and replacements, storage tank improvements, pump station upgrades, and pressure zone modifications. Our hydraulic modeling evaluates system performance, identifies deficiencies, and optimizes infrastructure investments.
Regulatory Compliance and Permitting Support — We prepare permit applications, compliance reports, operation permits, and regulatory submissions. Our regulatory expertise helps authorities maintain compliance, respond to violations, and implement corrective actions that satisfy requirements while managing costs.
Funding Assistance and Grant Applications — RETTEW identifies funding opportunities, prepares grant applications, develops preliminary engineering reports, and provides the documentation required for statewide financing authorities, USDA, EPA, and other programs, helping authorities secure financial resources for critical infrastructure investments.
