How does a septic tank actually work to process wastewater?
A septic tank in New Haven works by separating solids from liquids. Wastewater from your home enters the tank, where heavier solids settle to the bottom as sludge, and lighter materials like grease float to the top as scum. The liquid effluent then flows out to a drain field for further treatment by soil and bacteria. This natural process helps manage wastewater effectively when your home isn't connected to a municipal sewer system.
What are the signs that my septic tank in New Haven might be full?
Watch for several signs that your septic tank in New Haven might be full or having issues. Persistent sewage odors around your home or yard are a common indicator. Slow drains and gurgling sounds from toilets and sinks can also signal a problem. You might also notice unusually lush, green grass over the drain field area or even sewage backups into your home. These are all red flags that suggest it’s time for a professional inspection and pumping.
