About Us
Fifty years ago sewage treatment was pretty simple: dilution was the solution to pollution. Sewage was dumped into local rivers and creeks, and that was about it. But times were changing, and in 1955 sanitary engineer Robert E. Hamilton started a Joliet firm that would help develop some of the first waste water treatment plants at local municipalities and throughout the Midwest.

The business at 3230 Executive Drive in Joliet, Illinois has grown quite a bit from its first days in the corner of a bedroom in the home that Bob and wife Shirley Hamilton rented.

Those were "the early days of sanitary engineering," Bob Hamilton remembered in 2005. "In Chicago, their solution was dilution by dumping it in the river and sending it down here." Longtime residents know that the condition and smell of the Des Plaines River has changed quite a bit over the years, which in large part is a credit to the evolution of sanitary engineering.

Robert E. Hamilton Consulting Engineers planned the first municipal treatment plants for Frankfort, Minooka, Mokena and New Lenox. And, the firm helped develop a water system for the new Hillcrest Shopping Center in the late 1950s and the city of Crest Hill that developed around the retail center.

The office has expanded throughout its 50-plus years to a offer a broader range of engineering and the related fields of Transportation, Hydrology-Hydraulics, and Land Surveying.

Principals and company employees are involved in numerous charitable, civic and professional organizations from leadership in the Illinois Society of Professional Engineers, Lions Club and Rotary; to founding membership on the Will County Stormwater Committee, Will County Traffic Safety Task Force and Plainfield MainStreet; and service with the Joliet Junior College Foundation and the Conservation Foundation.

A combined total of over 200 years of engineering experience, joined with the extensive expertise of the rest of the technical and administrative staff, makes for a powerful municipal advocate in the fast-growing region of greater Will-Kendall-Grundy-Kane Counties. A policy of emphasizing client cultivation in Northern Illinois enables principal personnel to maintain intimate project involvement which, in turn, assures superior engineering services to every client. Services include Wastewater Collection and Treatment, Transportation and Traffic Engineering, Water Supply/Distribution/Storage and Treatment, Stormwater, Annexation/Site Plan/Subdivision Review, Construction Observation, Surveying, Standards and Ordinances, and creation and guidance in the implementation of infrastructure plans. It's these plans, and associated services, and the integrity and dedication of the firm responsible for them that allow governments to plan in advance for growth, rather that to simply react, as is too often the case. An eye for future generations guides all of our recommendations.
