Precast / Septic

At AAAZoellner, we manufacture Class #1/NSF approved concrete aerobic (Aeration Treatment Units or ATU’s) and non-aerobic septic tanks. In addition, we make grease traps, holding tanks, pump tanks, drip irrigation tanks, and low-pressure pipe (LPP) tanks, just to name a few. Our concrete tanks are built with 5000+psi concrete that utilizes rebar and structural fiber reinforcement. They are considerably stronger and less permeable than our competitors.

Then our tanks are delivered by heavy-duty knuckle-boom crane trucks. The 360 degree articulating knuckle-boom and 30 feet of reach offer more on-site versatility for difficult site conditions. *

Items to avoid in Onsite Treatment Systems

Plastic, rubber, scouring pads, dental floss, condoms, kitty litter, cigarette filters, bandages, hair, mop strings, lint, rags, cloths and towels do not decompose in an onsite treatment system. Inert materials build up solids and lead to system malfunction, clogging, or increased pump-out frequency.

Inert Materials

Medications, Cleaning Products, Plastic, rubber, scouring pads, dental floss, condoms, kitty litter, cigarette filters, bandages, hair, mop strings, lint, rags, cloths and towels do not decompose in an onsite treatment system. Particularly, inert materials build up solids and lead to system malfunction, clogging, or increased pump-out frequency.

Paper Products

Disposable diapers, tampons, sanitary napkins, cotton swabs, paper towels, facial tissues, baby wipes do not dissolve properly. Toilet tissue, lotioned, scented or quilted  and moist toilet paper in general do not dissolve readily in an onsite treatment system. Also, excessive amounts of toilet tissue at one time can lead to system malfunction, clogs, or increased pump-out frequency.

Food Waste

Do not put animal fats and bones down the sink. Additionally, grease, coffee grounds, citrus, melon rinds, corn cobs, or eggshells should be avoided. Garbage disposal use should be limited to waste that cannot be scooped out and thrown in the trash. Spoiled dairy products and yeasts from home brewing or baking may interfere with microbial process in your system.

Cleaning Products

Antimicrobial soaps and automatic toilet disinfection tablets may kill the organisms needed to consume waste. Avoid emptying mop buckets containing bleach down the sink.

Medications/Ailments

Do not flush expired medicines, as some will disrupt your treatment system and many can eventually find their way into the groundwater. If household members undergo oral or intravenous chemotherapy, the treatment system may require more frequent pump out intervals or the use of biological additives. Contact an onsite treatment system service provider to find out if such service is needed.

Commercial Additives

The U.S. Environmental Protection Agency and other authorities report that there is no evidence to support the use of additives with normally functioning onsite treatment systems. Some septic tank additives can harm the system. A normally functioning system does not require additives.

Chemicals and Toxins

The following materials will kill the microbes necessary for the biological treatment to occur: paint, paint thinner, solvents, volatile substances, drain cleaners, automotive fluids, fuels, pesticides, herbicides fertilizers, metals, disinfectants, sanitizers, bleach, floor stripping wastes, excessive use of household chemicals, and backwash from water softener regeneration.

Laundry Practices

To avoid overloading some systems, spread out laundry over the week instead of doing it all in one day. Excessive use of detergents, especially those containing bleach, can affect system performance. Liquid detergents are recommended over powders. Fabric softener sheets are recommended over liquid softeners. Use bleach sparingly, and at half the rate indicated on the container.
