Toilet don't flush guide:

What items and chemicals are safe and what items are not safe to flush down the toilet and into a private septic system? What may damage the septic tank or leach fields? This document explains how to extend the life of the septic system by being careful about what goes into it.

We provide a list of articles giving exact details about items that should not be flushed down building drains either because of the probability of clogging the drain waste vent system or because of the risk of chemical harm to necessary septic tank and drainfield bacteria, or finally, because of the risk of chemical contamination of groundwaters, nearby leaks, ponds, streams, and the environment in general. We also discuss & provide citations about chemical contaminants found in residential wastewater.

Diapers, sanitary napkins, tampons, photo chemicals, cleaners, garbage and even toys which find their way into building toilets and drains risk clogging the drain piping, distribution piping, or the septic tank baffles. In the photo at left, the inspector pointed to the bottle of acid and wondered how much photo chemical had gone into the septic system and worried about what that might mean for the health of the leach field.

Even if the septic drainfield field appeared to be "working" it might not be properly treating the septic effluent. It's best to keep diapers, sanitary napkins, chemicals, and the like out of your building drains and toilets. Garbage disposers also increase the solid waste load on septic tanks and may require that the tank be pumped more often.

Chemical Contaminants Found in Residential Wastewater & Their Sources

Plumbing drain should not receive these chemical contaminants (C) Daniel FriedmanThe focus of our "do not flush" advice provided in the article list above is practical: we list substances which are known to result in septic system blockage, clogging, failure, or contamination.

That more broad approach includes non-toxic materials such as coffee grounds and baby diapers or tampons, as our focus is on septic system maintenance and on preserving the proper functioning of the system piping as well as the health of the bacteria needed in the septic tank and in the absorption bed or soakaway bed to process various pathogens.

A very wide range of chemical contaminants can be found in residential wastewater, as a 1980 US EPA study documented in citing 129 contaminants that were targeted for survey.[3] However the chief tables most often cited in that study don't address concentration levels nor drainfield effects, and the study pointed out the difficulties in surveying private homes and uses of products that can produce chemical contaminants in wastewater.

[Our photo (above left) illustrates a source of chemical contaminants: dumping photo-chemicals down the drain and into the septic system.]
