More than one in five homes rely on a septic tank to treat their household wastewater, but these private water systems require routine maintenance to function correctly. The most significant maintenance task required is having your septic tank cleaned. If you’re new to owning a septic tank, this information can guide you to understand why and when septic tank pumping is necessary.

Why Is Septic Tank Pumping Necessary?

Septic tanks separate solid sewage from wastewater. While the wastewater that enters a tank is filtered out, the solid waste and scum remain. Bacteria help the solid waste decay, but some layers of sludge and scum build up over time, causing the tank to become full. When a tank is full, it can cause wastewater to back up into your home. 

When Does a Septic System Need to Be Cleaned?

A septic tank will exhibit several signs it needs to be pumped. Blocked drains might develop, causing foul smells to come from the drains or the tank’s drain field. Wastewater could also start to pool around your lawn. Eventually, the drains can become slow or gurgle, potentially causing major sewage backups. 

How Often Should You Schedule Pumping?

Septic tank pumping depends on a number of factors, such as the size of your household, the frequency of use, and the tank’s size. In general, septic tanks require cleaning every three to five years, but a family of four or larger that uses a smaller tank—such as 500 or 750 gallons—will need to have it pumped annually.
