Maintaining your Onsite septic system is very important. Having the knowledge as to what you may do to care for the system, when the system needs attention, and when you are due for service; is the key to a healthy Onsite septic system.


Standard Septic Systems vary size and design. In most cases on a residential system, the size of the Septic tank(s) and dispersal area are calculated on the number of bedrooms in a dwelling. Thereafter depending on the soils type, where the properties water table level is, and at what depth the restrictive layer(s) are in the soils; will determine the trench depth and lengths allowed for installation on your Septic drain field laterals.

Trench depths on a standard system (including cap & fill systems) vary between 12" to 36". In some cases you may find the laterals trench bottom deeper; which will place you in the category of seepage trench laterals.

Depending on several factors (which vary from site-to-site), your system may or may not require you to have an effluent pump (lift station) to discharge effluent from the tank(s) to the drain field.

Dispersal types range from equal distribution via gravity feed (from the tank to distribution box to laterals), serial distribution via gravity feed (from the tank to drop boxes to laterals), equal distribution via pump feed from tank(s) to a hydro-splitter which feeds the laterals equally via gravity, or serial distribution via pump feed (which is Pumped from the tank(s) to the first drop box and there after gravity takes over to fed the laterals).
