Each part of the system plays an important role in how wastewater is managed and treated on your property. When the time comes to schedule a septic system installation, understanding a few key terms can help you feel more confident about your service.
This is the main holding chamber for wastewater that flows from your home’s plumbing. Inside the tank, heavier solids settle to the bottom while oils and lighter materials float to the top. The tank’s job is to separate these materials, allowing only the partially treated liquid — known as effluent — to move on to the next stage.
Effluent is the liquid waste that exits the septic tank. It’s been partially treated but still requires filtration through the leach field before it’s safe for release into the soil.
After leaving the tank, the effluent travels through underground, perforated pipes. This area is called the leach field. The soil naturally filters and breaks down remaining contaminants as the water slowly seeps back into the earth, keeping groundwater clean and safe.
A failing septic system can lead to messy, unpleasant and even hazardous conditions. Watch for these warning signs around your home:
When it comes to replacing septic systems, installation by a professional is crucial. Our technicians can look over your system, identify the problem and determine whether a full or partial replacement is needed. Then, we can perform the upgrade while protecting your plumbing system from mishaps.
