My house has a septic tank is that bad? If you grew up in a house with a city sewer system, a house with a septic tank and septic system will seem a little different at first. But it’s not the end of the world,  you just beed to know a few things first. Here is our guide to having a house with a septic tank and septic systems.

What is a septic tank?

A septic tank serves as a wastewater treatment system for your house.  It is a tank made from concrete, polyethylene (hard plastic) or fiberglass, that accumulates all of the liquids and waste from a household. If it goes down a drain (sinks, toilets, bathtub washing machine), it passes through your tank.

The liquid is then removed from the tank periodically either through a pump in the house (liquid only), or a septic truck that removes all of the liquid and waste. The tank is usually buried underground with an access point sticking out of the ground.

 

How do I know if I have a septic tank?

If you don’t have a sewage line hookup you most likely have a septic tank or a cesspool. This tank can range in size from 750 to 1315 gallons. The difference between a cesspool vs septic tank are worth noting because cesspools are usually older and will have more things to consider when buying a house.

 

What is the purpose of a septic tank?

A septic tanks purpose is to gather all of the liquid waste and matter of a house when a sewer connection is not available much like a cesspool does. It them holds that material until it is pumped by a septic truck or the grey water is pushed out to a septic field or drain field. This is an area where the grey water from the house is returned to the water table of a long period of time.

 

How do septic tanks work?

Everything that goes down a drain in your house ends up in your  tank. Any liquids or solids that pass through your washing machine, dishwasher, toilet, bath, shower, garbage disposal all end up in your  tank. They all end up in the same tank eventually.

While some things settle in the tank other things pass through to your leach field or drain field (also known as a septic field). The three of these combined are what are commonly referred to as seepage.

There are two chambers in a tank, the first compartment gathers all of the sewage from the house. While the sludge settles, and scum forms on top the liquid then moves to a second compartment. In the second compartment the waste water is pumped periodically to a drain field.

 

What are the contents of a septic tank?

The tank has three parts that go into it, scum, wastewater and sludge.  The sewage from the house goes into the tank and then the solids settle to the bottom while the scum rises to the top, this scum looks exactly like you would expect… like scum.

The water in the middle is the waste water, or grey water, or effluent, and is eventually pushed out from the tank into a second compartment and then your leach field, (drainage field, or septic field depending on where you live). Your tank will need to be pumped regularly, how frequently will depend on the size of tank and the setup. You read more about septic tank pumping here.

How much does a septic tank cost?

The installation of a conventional septic tank will vary in cost. They typically range from $4,000 to $10,000 for the tank and system but depending on conditions the price can rise from there.

 

What about the solid waste?

The solids breakdown while they are in the tank but over time they gradually build up. As the tank fills up and you will need to contact a septic truck to come and pump out your tank.

For some households that do not have a manner of getting rid of their waste water into a drain field this can be every week, for others a year, or even 3-4 years depending on usage, circumstance, and size of tank.

 

Can you flush toilet paper in a septic tank?

Yes you can flush toilet paper down into your toilet tank. But that is it.

Paper towel, dental floss,  disposable diapers, cat litter, feminine products and other non biodegradable cannot be flushed down your toilet when you have a tank because it won’t break down and can clog in the line.

 

Do you need to use special toilet paper for a septic tank?

No toilet paper is meant to be flushed but the host of other things people through into a toilet can have a hard time in the tank and lead to clogging it. It is a good idea to not flush too much toilet paper at once as this can clog any toilet, result in you having to unclog the toilet.

 

What does a septic tank mean for my budget?

If you have a tank you will need to budget for it to be pumped. Finding a septic service is pretty easy. It’s likely your neighbors have one, there may be a sticker on the tank, or you can search for a septic tank cleaning near you.

You will need to pay for a pump/ cleaning whenever your septic tank is full.

Budget wise the pumping cost will vary depending on the size of your tank and the frequency of pumping. For example we have a drain field (more on those next) and a large tank. We get it pumped annually. Whereas the regulations changed for leach fields in our area and some houses need to have their tank pumped every week because they don’t have a drain field.

Make sure to ask about this before you make an offer on a house.

What affects the cost of pumping a septic tank?

There are several things that can affect pumping out your septic tank.

  1. The first is location of your house, if the truck has to drive a long way to get there, or has to drive a long way to dispose of the waste you could face a surcharge.
  2. Location of the  tank on the property is also an issue. Is it easily accessible or there are many obstacles in the way that need to be removed such as trees, soil or other large objects?
  3. Does the lid removed easily and is there a riser installed? If not, you could be charged because of the time involved to get the lid off.
  4. If the lid is not sticking out of the ground, or if the access point of the tank has been covered by soil it may need to be excavated and have a riser installed. In which case you may have to pay an excavation charge based on the flat or hourly rate depending on the commercial septic company, depending on the resources needed.
  5. Is the tank easy to find? If you lived there many years you probably know where your tank is located. For new homeowners they may not know where the tank is on their acre of land, and if a lot of time is needed in trying to locate it by the septic tank company. A charge can be easily avoided with a little bit of searching or asking neighbors or checking municipal records.

 

What is a leaching field

A leaching field, also known as a septic field or drain field, is a field where the grey water from the tank gets pumped out to and drains back into the water table over time. Having a leaching field can make things easier and less costly because the tank disperses the waste water rather than containing it allowing for the tank to go longer in between cleanings.

By having a leaching field you effectively get rid of the grey water in your system which means that you don’t have to call for a septic professional to come and pump your tank as often. Your municipality may have restrictions on how small a lot you can have a leaching field. We had over an acre of land so it met the needs of the area.

 

Aerobic Septic System

Aerobic septic systems are a type of  system that refers to an aerobic treatment system. These water treatment systems is like a mini sewage treatment plant that uses an aerobic process to breakdown sewage rather than an anaerobic process like the kind that is used in a conventional septic system.

 

How is an aerobic septic system different from a normal septic system?

Aerobic systems use the aerobic treatment of sewage in the tank to break down the solids in the wastewater to provide extra processing to the wastewater (effluent).

The aerobic bacteria breaks down the biological waste in the effluent and the remaining solids settle to the bottom of the tank, much like in a normal tank. This is the sludge that needs to be removed periodically when the tank fills up.

The next stage of the aerobic process is the cleaning or disinfecting of the wastewater where chlorine is used to disinfect the water to create an output that is deemed antiseptic. This last stage is necessary if the effluent is going to be used above ground. This treatment is done with special chemicals and is used to disinfect the effluent.

Check with your local municipality as to whether or not your land is suitable for an aerobic septic system as there are various local laws that may need to be complied with.

The main difference between what is considered a standard septic system is that an aerobic septic system creates a secondary effluent (waste water or grey water) which can be sterilized and used for surface irrigation. This means that the size of a drainage field can be cut in half under some circumstances.

Septic System Maintenance Plan

Talk to your septic tank cleaning professional about a maintenance plan for your tank. All tanks and households are different. The best thing you can do is talk with your cleaning professional and a set up maintenance schedule.

This should be established so that you can keep your  tank working properly, and also maintain the lifespan of your septic leach field. An inadequately maintained  tank will lead to a breakdown of the leach field resulting in higher cost down the road. Having your tank pumped regularly is also a good way to prevent a septic tank smell in your house.

Another good thing is to use toilet paper that is septic safe. Here are the best septic safe toilet papers.

 

Septic Tank Camouflage

Let’s face facts, a giant circle sitting on top of your yard is a little ugly. It’s a constant reminder of where your sewage is and it is a blemish on your landscaping. But like that rear projection TV in your basement, you are stuck with it. So what do you do?

If your septic tank cover is sticking out of the ground and you want to hide that big ol’ piece of plastic in the yard look no further than a fake rock cover.

We recently bought a rock cover from Dekorra and we absolutely love it. Normally these kinds of rocks are fairly obvious that they are fake but the ones from Dekorra are amazing. If you are looking to hide your tank lid then look now further than Amazon to get a larger look or to purchase click on the link below to go to Amazon.

 

Septic Tank Insurance

It’s always a good idea to make sure your insurance policy for your home covers your tank. Common issues that can arise from the  tank are when the pump fails and the tank starts to flow back into the house . This usually will happen at the lowest drain such as a shower or bathtub.

The best thing to do is to call your insurance company and ask them if your policy covers septic system failure and sewage backup. Many insurance policies will require a writer on top of the home policy to cover such things. It’s an extra cost but pumps fail and it’s a better thing to have than to risk.

At some point the tank will need to be replaced for most people this is when the pump quits but it’s good to know your pumps lifespan and talk to your tank professional about how often your pump should be replaced and if you are due.

 

Tips for your Septic Systems

One of the biggest septic tank problems is too much water going into the tank. If you are using a garbage disposal in your house, it will greatly speed up the time in-between septic tank cleanings, as all of that matter is still solid and fills up your tank quickly. Some reports have claimed that using a garbage disposal will fill up a septic tank 3 times quicker than without one!

Don’t plant trees around your tank, the tree roots can force their way in.  Doing so will cause your tank to crack and give you a host of issues.

Another tip is to be careful of leaks. If you have a toilet that is constantly running, or a leaky faucet you are filing up your tank faster than normal. It’s a good idea to fix those issues quickly. Otherwise you will be paying for more cleanings.

 

Final Thoughts on Houses with Septic Tanks

While this was a lot to take in, a house with a septic tank is pretty easy to maintain as long as you aren’t flushing things that shouldn’t be flushed. A filter before your pump will go a long way to preventing a lot of the issues.
