A Quick Guide to the Septic System

How a septic system works

The property uses a private septic system rather than a municipal sewer connection. Here is the short version of how it works:

1. All wastewater from the toilets, sinks, and appliances flows into an underground holding tank in the yard.
2. Inside the tank, heavy solids sink to the bottom and lighter material floats to the top. The clarified liquid in the middle flows out gradually into the drain field — a network of buried pipes that releases water slowly into the surrounding soil.
3. Naturally occurring bacteria in the tank break down the organic solids over time. The system takes care of itself as long as it only receives what it is designed to handle.

The system works reliably for all normal household use. The signs around the property exist to protect it from the specific things that disrupt this process — not to make everyday use complicated.

Toilets

A note on "flushable" wipes

The word "flushable" on wipes packaging means the wipe can physically travel through a toilet — not that it is safe for a septic system. Unlike toilet paper, wipes do not break down in water. They accumulate in the tank and eventually clog the drain field, which is an expensive and disruptive repair. Please treat all wipes as trash regardless of what the packaging says.

Trash cans are provided in each bathroom for exactly this purpose.

Kitchen sinks and drains

The kitchen drain connects to the same septic system. The sign near the sink asks that only non-solidifying liquids go down the drain. Here is what that means in practice:

Handling grease and oil

Let pans cool after cooking, then wipe or scrape grease and fat into the trash before washing. Even liquid cooking oil that goes down the drain can solidify in the pipes or the tank over time, building up deposits that eventually cause blockages.

The garbage disposal

You may notice a garbage disposal in the kitchen sink and wonder how that fits with the signs about the septic system. It fits — with an important distinction about how it is meant to be used.

What it is for

The disposal is there to handle the small bits of food that come off plates and cookware during the normal pre-rinse before loading the dishwasher. Think of it as a fine strainer for incidental particles — a few grains of rice, some sauce residue, small vegetable scraps that slip through while rinsing. That is its purpose, and it works well for that.

What it is not for

The disposal is not a food waste bin. Scraping significant amounts of food into the sink and running the disposal sends a concentrated load of organic material into the septic tank faster than the bacteria can break it down, which disrupts the system over time.

Please do not use the disposal for:

• Scraping plates with significant food left on them — scrape those into the trash first
• Coffee grounds
• Grease or cooking oil
• Fibrous vegetables — celery, corn husks, artichoke leaves
• Starchy foods in any volume — pasta, rice, potato peels expand and can clog
• Bones or anything hard

The simple rule

Scrape plates into the trash. Pre-rinse them at the sink before loading the dishwasher. Let the disposal handle whatever comes off naturally during that rinse. That is the full intended use.

The drain field

The drain field — the underground network of pipes that disperses treated water into the soil — runs beneath part of the front yard. It is not marked, but it covers a significant area there. The fenced back yard is not affected.

Please do not park vehicles or place heavy objects on the grass. The weight can compact the soil and crush the pipes below, which are not designed to bear that kind of load. This is also noted in the arrival guide under parking.

The grass in this area may appear slightly greener or grow faster than surrounding areas — this is normal and simply reflects the moisture and nutrients returning to the soil through the drain field.
