We are a full service septic and drain cleaning company serving the Will, Grundy, Kendall, Kankakee, Dupage, LaSalle, Livingston, 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 nine 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 gravel less 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. We do trenchless pipelining also known as CIPP (Cured in Place Pipe) & our licensed and certified installers by LMK Technologies.

You could say we are high-tech but old school. We have a 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! And 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 allow us to dispatch the closest technician to your site.

Modern Equipment & Technology Make The Difference

We have some of the newest and most innovative equipment available today for our line of work. This allows us to finish 98% of our jobs in one day. By reinvesting and updating our equipment we can meet your needs and keep up with today’s rigorous schedules. Our machines are laser controlled for a more accurate and level trench bottom. Not only is our equipment of high quality standards, but we use only the highest quality material. Our 4″ piping is schedule 40, which is much stronger than SDR 35 pipe. We use plastic distribution boxes with sealed O-rings, and water tight air tested concrete septic tanks. Also all of our equipment has tracks to eliminate ground compaction. This is a very important point. Soil compaction during site excavation, stockpiling of dirt, and backfilling inhibits the longevity of a septic system’s life. Smearing of the soil pores, which will happen if a septic system is installed in wet conditions, will also jeopardize the system. We have fabricated side cutter tips on our excavator bucket to eliminate smearing of the sidewalls.

All of our route tickets, pumping reminder notices, invoices, and scale drawings are computer generated. We also keep accurate records of all tank, and field locations. This has helped many of our clients when doing landscaping, building decks, swimming pools, room additions, etc.. The software that we use to log all of our customers data in was designed & developed by Ritam Technologies, LP Mark, Noah and the rest of the staff have been great to work with. Their support staff has helped us with programs designed around our special needs. Anytime we have had a problem they have been there to resolve it. In 2011 we finally converted our last pc over to all Mac desktop computers. We have two-Mac-Mini servers that our data resides on with in house & off site backups for all of our database.

On an average we install 100-150 On site Wastewater Treatments Systems per year. These will consist of new systems & repairs. Our loyalty is to the Residential customers who have helped us to become the largest septic installer in the surrounding counties. We have also provided septic systems for some of the largest Commercial & Industrial projects in our area. Our company has installed systems at the former Arsenal property. Including temporary onsite systems for the demolition crew, and then for the new Railroad & Trucking spur and Waste Managements Landfill site. A&R’s Trucking facility in Will & Grundy counties, Aux Sable Liquid Products, Joliet Park District’s Horticulture Center on Gougar Road, the Joliet Junior College Greenhouse project on Houbolt Road and numerous other plazas and churches throughout the surrounding area. It is a great sense of accomplishment to be involved with projects that are providing more jobs to the local communities.

Our best asset is that we are family owned and operated. Now you know what you will receive from us. Will you receive the same quality and personal care from the other companies? Every business has different overheads. We have the personnel, equipment and knowledge that a Full Service Septic & Drain Cleaning Company should have. There is always someone out there that costs a little less or a little more. But as you can see you will get quality & professionalism with Zeiter’s Septics Unlimited, Inc.

Full Service Septic Company vs. Non Full Service or Excavating Co.

They may cost less money but remember they are making money on the excavation. But more important is what happens before they leave and after they are gone. When we leave the job the septic system is ready to use. Do they know about soils & how septic systems work? Are they locating the septic in the proper area? Do they educate you the homeowner consumer on what you need to know about On site Wastewater Treatment Systems? Do they keep accurate tank & box locations for when you want to plant trees, put up a swimming pool or shed? What happens when a part of the system gets damaged from a concrete truck or during backfill or final grade/landscaping? And unfortunately this happens way too often. Do they have anything on file where to dig? And how are they going to see what they are trying to fix if there is effluent in the hole, you need a vacuum truck to pump the effluent out so you can work. This and much more is what a full service septic company will provide for you. The excavating company can not. We work alongside all the excavating companies out there and they are very reputable and professional at what they do. But excavating and installing an onsite Wastewater Treatment System for a home or business is not the same as excavating for a basement..

Our Bottom Line!

We want your business, and we will work hard to keep it. Zeiter’s Septics provides fast, dependable On site Wastewater Treatment Systems and septic tank service. We are available for residential, commercial, and industrial sewage treatment systems, including churches, restaurants, schools, recreational parks and centers, and other institutions.
