Information

A septic system consists of six main components. First, a house sewer line transports waste to the septic tank. The tank then allows solids to settle while liquids remain. Since 2000, all septic tanks have included outlet baffle filters that need cleaning during tank pumping. Distribution piping then carries effluent from the tank. A liquid distribution box may be used to evenly distribute effluent through the leaching system. Finally, the leaching system, which can include fields, trenches, pits, beds, or galleries, purifies the effluent by filtering it through soil.

For an average-sized family of four to five members, septic tanks typically require cleaning every two years. However, larger families or homes with food disposal systems may need more frequent cleaning to maintain optimal system performance.

Regular septic tank cleaning is essential to prevent the buildup of undigested material, known as sludge. While bacterial action breaks down some solids, sludge accumulates over time and must be removed. If not pumped out regularly, these solids can reach high levels and be carried into the absorption field, potentially clogging pipes, stone, and surrounding soil.

Indeed, the number of bedrooms does influence the required septic system size. For instance, a 4-5 bedroom house typically requires a 1250-1500 gallon tank. The average water usage is estimated at 60 gallons per person per day. If occupancy exceeds the average for the dwelling size or if the septic tank is smaller than state regulations, biennial cleaning is recommended until experience indicates a longer interval is suitable.

Septic system failure can result from several factors. These include neglecting regular inspections and cleanings, lack of understanding about proper system use, and poor soil conditions or inadequate system design and installation.

Indicators of septic system failure include noticeable sewage odors, visible sewage discharge on the ground, wet or muddy patches in your lawn, unusually lush green grass, slow-draining fixtures in bathrooms or kitchens, sewage backup into your house, and sewage flowing back from the leach field into the tank, which can be observed during tank cleaning.

To prevent septic failure, ensure regular cleaning of your system. Avoid disposing of grease and coffee grounds down drains. Additionally, refrain from flushing items such as diapers, cooking fats, paper towels, cigarette butts, personal wipes, and feminine products down the toilet. These practices help maintain your septic system's efficiency and longevity.

In the event of septic failure, first contact your town sanitarian or health officer for guidance, as pumping and cleaning alone may not resolve the issue. Next, reach out to a qualified septic repair company, ensuring they are licensed and well-recommended. We recommend verifying if the contractor is a COWRA member, as these professionals are committed to high standards and stay updated on current methods through continuing education.
