The average residential septic tank can hold around 950 gallons of water. This number provides a rough idea of the tank's daily processing capability. According to the OSTDS guidelines, an average person is assumed to use 50 gallons per day, so a family of 4 may produce up to 200 gallons per day.
Water overload may harm the septic tank's bacteria. The bacteria inside the tank feed on solids to speed up the breakdown. As such, if the tank lacks adequate bacteria, that causes solids buildup that later turns into sludge.
The time it takes for a septic tank to fill up depends on several factors such as tank size and the number of people living in a household. Scum and sludge should never be more than 1/3 of the working capacity in any septic tank. Typically, you will need a pump out every two years based on a family with normal usage.
If your septic system is functioning, it drains excess liquid to the designated leach field. However, if there's more water in the tank than it can drain, the surplus water makes it harder for the solid waste to dissolve.

The septic tank has a specific capacity and can only handle a limited amount of wastewater at a time. If excessive amounts of water enter the septic tank, it can overflow and cause water to pool in your yard. To avoid this, space out the showers.
SEPTIC TANK OVERLOAD
An overloaded septic system does not allow solids to adequately settle and limits necessary bacterial activity. This increases the risk of solids moving into and clogging the drain field, which can reduce the septic tank's efficiency or lead to a complete breakdown of the system.
In general, a septic tank should be inspected every 1 to 3 years and pumped every 3 to 5 years.
When heavy rainfall saturates the soil around your septic tank, it limits the system's capacity to release liquids into the soil. This can cause abnormally high levels of liquids to fill up the tank.

A septic tank should always be “filled” to its normal liquid level, or the bottom of the outlet pipe which carries effluent to the absorption area. This normal liquid level is usually between 8” to 12” from the top of the tank on average (see picture at right).
