Proud to
Serve the
Water
Community
RPS Engineering was proud to attend IWPC 2026 in East Peoria, Illinois — connecting with the wastewater professionals we’ve served with American-made cover solutions for over 50 years.
RPS aluminum flat panel covers installed on a municipal wastewater clarifier
Covers Built to Last
Aluminum flat panel covers installed on a municipal wastewater clarifier — designed to sit airtight, control odors, and lift out cleanly when operators need access. No caulking. No hassle.
This is the kind of installation RPS Engineering has been delivering to wastewater facilities across the U.S. since 1975. Custom-fabricated to fit your exact tank, built domestically, and engineered for the long haul.
Partners in Clean
Water Infrastructure
IWPC brings together the engineers, operators, and professionals who keep Illinois’s water clean — and RPS Engineering is proud to be part of that community. We’ve been designing and fabricating cover systems for wastewater treatment facilities since 1975, working with municipal plants and industrial operations across the country.
Conferences like IWPC matter to us because they do what we try to do every day: put the right people in the same room. Whether it’s a new odor control challenge, a clarifier that needs custom coverage, or a launder that hasn’t been upgraded in decades — we’re here to help solve it.
All of our aluminum wastewater cover systems are domestically sourced and fabricated in Elgin, Illinois — with typical lead times of 4 to 6 weeks from design drawings through delivery.
Our cover systems are designed to be airtight — keeping odors contained and protecting workers — while remaining removable for routine inspection and maintenance without recaulking.
No two tanks are the same. Every RPS cover is engineered to your exact dimensions — flat panels, domes, launders, or baffles.
Fiberglass, aluminum, and stainless steel options — built in the U.S.A. for the demanding conditions of municipal wastewater and dirty water applications.
Centrally located outside Chicago for fast nationwide shipping — typical wastewater cover lead time is 4 to 6 weeks from design drawings through delivery.
