Although many Hill Country homeowners use septic systems, they are still a mystery to most people. We get asked lots of questions about septic systems, but the three we hear most are about septic pumpings/cleanings.
Why should my septic tank be cleaned?
Cleaning your septic tank is the key to the life of your septic system.
The purpose of the septic tank is to separate the wastewater from the solid waste and allow only the wastewater to enter the soil absorption field. The less frequently the tank is cleaned, the more solids are likely to enter the soil absorption field.
When this occurs, your soils and drainfield will clog and lead to system failure. In most instances, the entire system will have to be brought up to current regulations set by the TCEQ and your local permitting authority — this usually requires installing an entirely new system.
How do I know if my septic tank is full?
In a way, your septic tank is always “full” — between pumpings it will fill up to a certain level as it is used.
The question you really need to ask is, “How do I know how much sludge is in my tank?” The only way to know that for sure is to open up your septic system’s lids. If you are scheduling routine pumpings, you should not have a problem with sludge buildup.
How often should my tank be cleaned?
A conventional septic tank should be pumped every 3 – 5 years, depending on the size of the tank and the household wastewater usage. For example, a family of six on a 1000-gallon tank will need to pump out the tank more frequently than a family of three on a 1000-gallon tank.
In Bexar County, the tank is required to be pumped/cleaned at least every five years in order to renew the system’s License to Operate.
