Backbone of Community Infrastructure

When you’re planning to build, expand, or develop, experts in utility infrastructure will help ensure your project connects reliably to essential services. Understanding existing sewer and water systems, evaluating collection options, and planning for future capacity help save money and build confidence. RETTEW brings this expertise to every project, from planning through construction, delivering reliable utility infrastructure your community can depend on for generations.

With more than 50 years of dedicated service, we’ve built our reputation on proactive responsiveness and dependable partnership. Aging infrastructure doesn’t wait for convenient moments, which is why RETTEW’s team stands ready with proven solutions and reliable communication. Whether you’re replacing deteriorating lines, extending service to underserved areas, or implementing new designs to meet changing conditions, we’ve earned the trust of hundreds of municipalities and utilities who know we’ll be there when it matters most.

Collection System Expertise

At RETTEW, we know every community has unique infrastructure challenges, so we deliver strategic, customized solutions. We become an extension of your team, thinking critically and creatively to complete each project. You receive personalized solutions, budget efficiency, and enhanced safety, not one-size-fits-all answers.

Before you commit to major infrastructure investments, RETTEW’s comprehensive feasibility studies evaluate collection alternatives, identify system limitations, and explore long-term needs. We examine capacity, cost, regulatory compliance, and timelines so you can make informed decisions. When you’re ready for Act 537 planning or comparable state regulations, we help you navigate the permitting process to ensure regulatory approval and community protection.

We know your gravity sewer system needs to perform reliably for decades, so we evaluate site conditions, flow rates, and regulatory requirements to design proven solutions across varying terrain. When gravity flow isn’t feasible, we design pump stations for efficient operation with minimal maintenance. Alternatively, where site constraints or economics demand a different approach, we design innovative pressure and vacuum sewer solutions that reduce your project costs by eliminating expensive excavation.

Making projects affordable starts with securing the right funding. We identify opportunities that can significantly offset your costs and then guide you through the grant process. When construction begins, our resident project representatives remain onsite to ensure quality, maintain schedules, stay within budget, and keep your community informed.

Utility Design in practice

A regional authority operated three 1970s-era sanitary sewer pump stations that were approaching the end of their useful life and posed operational risks. The challenge was to expand and modernize these facilities within constrained sites while maintaining continuous system operations. RETTEW provided comprehensive services from condition assessments and hydraulic evaluations through final design across civil, mechanical, process, and electrical engineering disciplines. We coordinated with regulatory agencies to address constructability, permitting, and operational requirements while confirming each design followed asset management principles to optimize lifecycle costs and support long-term maintenance. The modernized pump stations replaced aging infrastructure with efficient systems that improve reliability, capacity, and redundancy, positioning the authority to meet future capacity needs.

An energy production client needed a pump station and waterline to support aggressive operational schedules with minimal downtime. RETTEW designed the facility with components matching the client’s existing installations for cost-effective maintenance and equipment replacement. We also installed automated valve operators for remote control, eliminating manual operation. The design incorporated redundancy so any line could be down for repairs without impacting operations. RETTEW provided complete design services from concept through construction, coordinating multi-disciplinary efforts and preparing specifications and instrumentation diagrams. The resulting pump station and waterline have enhanced the client’s water distribution assets and operational capacity.

After identifying three neighborhoods with failing on-lot septic systems through comprehensive groundwater testing, RETTEW designed a public sewer extension system to serve these residential areas. Our investigations revealed septic failures were impacting private drinking water wells, creating potential health hazards. The completed project connected numerous homes to the public sewer system, eliminating environmental concerns and protecting water resources.

RETTEW completed a comprehensive water line replacement along a busy urban street, working entirely within the PennDOT right-of-way. This complex urban project involved replacing aging infrastructure while simultaneously increasing line capacity to accommodate future growth and improve fire protection capabilities. Our careful planning and coordination with local authorities even minimized traffic disruption throughout construction.

Infrastructure as a Long-Term Investment

At RETTEW, we empower informed decision-making through comprehensive planning and innovative utility solutions. Understanding municipal financial constraints, we develop phased implementation plans that make projects affordable and reduce impact on residents and rate payers. Our integrated approach combines engineering design with GIS mapping and asset management, giving you a complete picture of your infrastructure for long-term planning and significantly improving your grant eligibility.

Built on decades of client trust, RETTEW’s relationships extend beyond project execution. We act as trusted advisors from the earliest stages, anticipating challenges, navigating complex permitting, and providing strategic insights that align with your budget and future growth. We’re committed to being your strategic partner in addressing infrastructure challenges and promoting decisions that benefit your community.
