Septic Tank: General

How do I locate my septic system? How can I learn more about my property’s septic system?

Obtain a copy of your property’s septic system record drawing (usually referred to as an “as-built”), a diagram showing where your system components are located. You can obtain your property’s as-built from your local health department or health district–some allow you to search for your as-built online.

How do I know my septic system is in good working order?

Lentz Septic Tank Service performs a septic system evaluation when we pump your tank. Some health departments and districts can perform this service prior to pumping, usually for a fee. If you suspect your system is having issues because you are noticing slow drains, gurgling toilets, or wet spots in your yard, getting the septic tank pumped out is usually a good idea and can help these issues. Contact us if you have any questions regarding your system functionality.

Septic Tank: Pumping

Why do I need to  have my Septic Tank pumped out?

Most conventional septic tanks built after 1975 feature two concrete, fiberglass, or polyethylene containers buried underground. Solid waste accumulates most in the first compartment, settling at the bottom and forming sludge. Some solids also settle in the second chamber. Bacteria break down much of this waste, but it can’t eliminate all organic material from the tank.

If septic tank sludge isn’t removed with periodic pumping, it continues to accumulate and may overflow into the drainfield. Eventually, this may cause drainfield plugging and failure, requiring costly repairs to get the system up and running again.

Septic tank pumping involves removing liquids and solids with a vacuum truck, which transports and safely disposes of the sludge elsewhere. As long as you keep up with routine maintenance, it should be fairly easy for the vacuum to remove solids from the tank. If the sludge in a neglected container is thick and heavy, the process may be more difficult and time-consuming, increasing the cost of pumping.

Clearly, it’s worth keeping up with septic tank pumping for your peace of mind and the continuing functionality of your plumbing system.

I’ve been in my house for 10+ years and never pumped my Septic Tank. Why should I be concerned?

Over time sludge and scum build up in the septic tank and unless it is removed it will flow into the drainfield, clogging the soil pipes. Once a drainfield is clogged, it must be replaced, which is an expensive repair, costing anywhere from $2,000 to $10,000 or more. It is also possible that you could have a leak in the tank.

In either case, you risk contaminating ground and surface water resources, which could affect you or your neighbor’s wells or nearby streams and other water bodies. And finally, you may eventually have a plumbing backup in your home.


How often should I have the Septic Tank pumped?

How often you need to pump depends on the size of the tank, the number of people in the household, and the amount and type of solids. A septic tank should be in- spected annually to check for needed repairs and pumped as needed, usually every 3 to 5 years. Some alternative systems that are more complex may need pumping more frequently. If you are unsure if your tank needs pumping, have it inspected and get a recommendation for how many years you can go between pumping. Write this schedule down on a maintenance chart or where you keep your maintenance records and stick to it.
