About Us
Company Information
D.C. Works, Inc., Founder, Bob Warfel, was involved with the septic and sewer system industry since 1964. Mr. Warfel had installed over 1500 aerobic sewage treatment units in 15 years.In 1991, Mr. Warfel had rocks made to cover the aerobic sewage treatment units, lift pumps and pipes because of customer complaints that lids and pipes sticking above ground are unsightly.
In 1998, Mr. Warfel quit installing and repairing septic systems, sewers, and aerobic sewage treatment units and started D.C. Works, Inc. D.C. Works, Inc. makes and sells various types of fake rocks. Soft pillow foam rocks can be used for school plays, church productions, movie sets, and trade shows. Polyurethane rocks help hide unwanted objects, or they can be used for landscaping purposes. All of our polyurethane, foam, and rubber rocks are made at our shop in Northern Illinois.
Our lightweight rocks made out of a hard polyurethane plastic, can easily be moved but are strong enough to stand on. The rocks are heavy enough that normal winds won’t blow them away. Attractive garden settings can be created using decorative fake rocks.
Rocks can be made with patented hidden air holes to help prevent moisture from building up, and so vent pipes and motors can get air. All rocks have 2 or 3 colors on them to make them realistic looking, and they can be ordered in any color or combination of colors.

Even birds like our rocks!
ROCKS CAN HIDE:
City sewer clean outs, manholes, wells, utility boxes, septic tank risers, vent pipes, chlorinator pipes, lift stations, ATU’s aerobic treatment units, back flow preventer, surveillance equipment, rocks to hide the back side of flood lights, and rocks with holes hides pest control boxes.
We do custom work and can put addresses, names or logos on rocks so that they look chiseled.
