About Us

Zeiter’s Septics Unlimited Inc.

We are a full service septic and drain cleaning company serving the Will, Grundy, Kendall, Kankakee, Dupage, DeKalb, LaSalle, Livingston, Lee, Kane, Cook & Bureau Counties. We are located at 2400 N. Route 47 in Morris Il.  This location is a center point to all of the counties we serve. We have easy access to all of the major highways which is important to us because we are a service based company serving twelve counties. This allows us to get our crews to a job site quickly.

We install and repair all types of septic systems, from the conventional gravel field, or the gravelless chamber system to today’s mechanical systems, which are miniature sewage treatment plants for the home or business. We also do lift stations, jetting, rodding, pump tanks, TV camera inspections, and site clearing. Most people do not realize that we are one of the area’s largest drain cleaning companies. We can clean a kitchen sink line as well as the septic line or sewer lateral – even roadway culverts!

Our  Experience

You could say we are high-tech but old school. We have staff that actually answers the phones. Are you sitting down? They actually have been trained and are very knowledgeable about septic systems, OMG. Plus, they are nice too, holy cow! This happens 5-days a week from 7-4pm – no way it’s too good to be true. Yes, we do have a sense of humor here 😉 But it’s all true and, unfortunately, a rare experience these days with most companies. Sarah, Tina, Gabe, and Tammy can make you feel welcome and answer any and all of your questions. Our office keeps in contact with our men in the field throughout the day via smartphones. We have GPS on all of our vehicles that allows us to dispatch the closest technician to your site. We can send out work orders with directions and one touch calling to the customer to keep them moving safely and efficiently.
