How to Find a Septic Tank and Manhole Cover

People frequently contact me through e-mail to inquire where they can find the septic tank cover for a septic tank, the manhole, or how to locate a septic tank in its natural state. Which is invariably met with the response “I don’t know.” Our plumbing how to will demonstrate that septic tanks and covers are never found in the same location, making it difficult for even the most experienced homeowners to make their way to the septic tank lid.

Check your building plans they often show you how to locate a septic tank.

It might be difficult to locate an aseptic tank, distribution box, or septic covers. The first thing you should do is double-check your original construction blueprints. Because these construction plans will frequently show you the exact placement of the septic tank or manhole covers for septic tanks, it is important that you keep them on hand. If you do not have your building plans, check with your local office of zoning to see if they already have a copy of your plan. Even if the septic system is still relatively new, there is a strong possibility they will, although many states do not save any of the earlier documentation.

It’s also possible to locate whichseptic tank service installed the system, and that company should be able to tell you exactly where the septic tank and/or septic tank lid are located.

How to find out where a sewer main exits the house.

If none of these options work, you will need to locate the point at which your sewage main exits your home. Whether you have a basement or crawl space, you should examine inside to see if there is a 4 inch black pipe coming out of the foundation and where it goes. It is necessary to locate the lowest drain in your home if you do not have a basement or crawl space, or if your sewage main is located beneath your home’s foundation, in order to complete this task. This is normally where a floor drain is located, and it is also most likely where the sewage line will exit your house.

Use a tile probe to find the pipes leading to the septic tank.

Having located your sewage main and having a general notion of where the sewer pipe exits the home, you will need to step outside and probe the ground directly next to your foundation with a tile probe or a 12-inch or 14-inch stainless steel rod until you locate the sewer pipe. However, if you push too hard, you may wind up poking a hole in the drainpipe, which is particularly dangerous if the drainpipe is an older type of cast iron pipe. Once you’ve located the main line, you’ll want to go on to the next step: locating the septic tank.

The majority of septic tank systems are located between ten and twenty feet away from your property.

Septic tanks and septic tank lids are two types of septic tanks.

The manhole cover for the septic tank may be found here.

How to locate a distribution box.

At the very least, it should be a little easier to locate the distribution box. It is normally around ten to twenty feet away from the septic tank, and you can sometimes tell it is there just by looking at the way your grass grows in the spring and summer. A common occurrence is that the grass will be greener above the drain lines, and you will be able to observe a pattern on the lawn where the lines meet together, which indicates the location of your distribution box. Other than that, you’ll have to place the distribution box in the same manner as you did with the septic tank.

Some of the things you can find while locating your septic tank are:

  • Soils with a lot of clay. Clay soils can be difficult to penetrate, and once a probe is inserted, it can be very difficult to extract it
  • Rocky soils can also be difficult to penetrate. You believe you’ve found the tank, so you begin excavating, only to discover a rock. And this is something that may happen over and over. Deep-level systems. Tracking and digging in a hole that is more than 2 or 3 feet deep may be a genuine pleasure. Pipes that appear to twist and twirl before disappearing into nothingness are common in older systems.

It is recommended that specialists like Septic Tank Service do this type of work (some pumpers merely pump tanks; they do not find the tank). Often, simply by glancing at your house, a professional plumbing expert will be able to figure out exactly where everything is.

In addition, if they are unable to locate it immediately, they still have all of the necessary equipment and plumbing tools to locate the septic tank’s lid much more quickly than you can.

How Your Septic System Works

Underground wastewater treatment facilities, known as septic systems, are often employed in rural regions where there are no centralized sewage lines. They clean wastewater from residential plumbing, such as that produced by bathrooms, kitchen drains, and laundry, by combining natural processes with well-established technology. A conventional septic system is comprised of two components: a septic tank and a drainfield, often known as a soil absorption field. It is the septic tank’s job to decompose organic matter and to remove floatable stuff (such as oils and grease) and solids from wastewater.

Alternate treatment systems rely on pumps or gravity to assist septic tank effluent in trickling through a variety of media such as sand, organic matter (e.g., peat and sawdust), constructed wetlands, or other media to remove or neutralize pollutants such as pathogens that cause disease, nitrogen, phosphorus, and other contaminants.

Specifically, this is how a typical conventional septic system works:

  1. All of the water that leaves your home drains down a single main drainage pipe and into a septic tank. An underground, water-tight container, often composed of concrete, fiberglass, or polyethylene, serves as a septic system’s holding tank. Its function is to retain wastewater for a long enough period of time to allow particles to sink to the bottom and form sludge, while oil and grease float to the surface and produce scum. Sludge and scum are prevented from exiting the tank and moving into the drainfield region by compartments and a T-shaped outlet. After that, the liquid wastewater (effluent) exits the tank and flows into the drainfield. The drainfield is a shallow, covered hole dug in unsaturated soil that serves as a drainage system. Porous surfaces are used to release pretreated wastewater because they allow the wastewater to pass through the soil and into the groundwater. In the process of percolating through the soil, wastewater is accepted, treated, and dispersed by the soil, finally discharging into groundwater. Finally, if the drainfield becomes overburdened with too much liquid, it can flood, causing sewage to flow to the ground surface or resulting in toilet backups and sink backups. Finally, wastewater percolates into the soil, where it is naturally removed of harmful coliform bacteria, viruses, and nutrients. Coliform bacteria are a kind of bacteria that may be found in the intestines of humans and other warm-blooded animals, with humans being the most common host. As a result of human fecal contamination, it is a sign of this.

Do you have a septic system?

It’s possible that you’re already aware that you have a septic system. If you do not know, these are tell-tale indicators that you probably do:

  • You make use of well water. In your home, the water pipe that brings water into the house does not have a meter. In the case of a water bill or a property tax bill, you will see “$0.00 Sewer Amount Charged.” It is possible that your neighbors have a septic system

How to find your septic system

You can locate your septic system once you have confirmed that you have one by following these steps:

  • Taking a look at the “as constructed” drawing of your house
  • Making a visual inspection of your yard for lids and manhole covers
  • Getting in touch with a septic system service provider for assistance in locating it

Failure symptoms: Mind the signs!

A bad odor is not necessarily the first indicator of a septic system that is failing to work properly. Any of the following signs should prompt you to seek expert assistance:

  • Water backing up into the drains of homes and businesses
  • It is especially noticeable in dry weather that the drainfield grass is bright green and spongy. The presence of standing water or muddy soil near your septic system or in your basement
  • A strong stench emanating from the area surrounding the septic tank and drainfield

Septic Tank Covers: A Comprehensive Networx Guide

As estimated by the Environmental Protection Agency, septic tanks, which are devices for treating wastewater in isolated locations not linked to a larger public or private sewage system, are used by 25 percent of houses in the United States. For rural locations such as Virginia Beach, this is extremely relevant. The tank is located outside the home and is connected to the house via pipes. It includes a detachable lid, which is known as the septic tank cover (or manhole cover). Septic tank covers are often the only visible components of septic systems, and they are often the sole points of entry.

Find out the truth about septic tank covers by reading this article.

Types of Septic Tank Covers

We recommend that you have a professional plumber install concrete septic tank covers for you. Septic tank covers made of concrete are long-lasting and sturdy. It is expected that these manhole covers would survive for many years and will be able to withstand enormous loads without cracking or breaking. Of course, the additional weight of the concrete increases the cost and difficulty of the installation process. Accessing the system through a concrete septic tank lid may also be more difficult, but the added durability is well worth the effort.

Steel and plastic septic tank covers are available as alternatives, and while both may allow for faster access and installation, they are less durable and have additional drawbacks. Steel manhole covers are prone to rusting, and plastic manhole covers are prone to cracking.

Reasons to Install Decorative Septic Tank Covers

No matter what type of septic tank cover you choose to install, we recommend that you include a decorative element on top of the cover to complete the look. The addition of them is intended to be both aesthetically pleasing and functional. Septic tank lids are frequently covered, or at the very least difficult to detect, behind the surrounding grass or vegetation. If your septic tank cover is below the surface of the ground, you must take care not to trip over it or run over it with a lawn mower to prevent damage.

  • You may also get septic tank covers that are specifically designed to be ornamental.
  • They are particularly handy for covering huge, bulbous plastic septic tank lids, which can be difficult to work with.
  • When selecting a septic tank cover, use caution.

5 Reasons to Install Septic Tank Risers

Most homeowners consider their septic system to be a “out of sight, out of mind” service that receives little or no attention unless there is a problem. Septic systems are buried underground, and if you aren’t sure where your tank and its components are, it might be tough to discover your access ports or manhole covers if you aren’t familiar with your property’s layout. Septic tank risers are a straightforward, cost-effective solution to this problem that can result in significant long-term savings.

  • What is a septic tank riser and how does it work?
  • Risers, sometimes known as “extensions,” are available in a variety of heights to raise any access port up to grade.
  • Because the riser extends from your tank entrance to the lawn surface, it makes it much easier to reach your septic tank for pumping, maintenance, and inspections than it would otherwise be.
  • Digging down to your septic tank lid or access port and fitting the riser to the entrance are the steps involved in installation.
  • Then we’ll fill the area around the pipe with earth and put the lid on top of it once it’s in place.

To make the lid integrate smoothly into your yard and landscaping, you are invited to put grass or mulch around the top of the lid. The AdvantagesWhen it comes to septic tank risers, there are a plethora of advantages to consider.

  1. The expense of installing a riser is one-time, but the advantages are long-lasting. Once the extension is in place you won’t need to pay for it again and your tank will be simple to reach for pumping, maintenance and inspections
  2. No more looking for your access ports! When we put your manhole cover up to grade, it will be clearly visible at all times
  3. There will be no more digging! This is especially useful during the winter months, when digging out a buried manhole cover might take several hours and need specialized equipment. This is in addition to the mess that it can create in your yard if the lid is buried several feet down
  4. Nonetheless, it saves you money. Time is money! Furthermore, since it is simpler to reach your septic tank, our staff can complete your task or resolve your problem much more quickly
  5. It is critical to understand where everything is located. If you’re planning a new patio, home extension or backyard renovation, knowing exactly where your tank and its components are located is a tremendous benefit. We’ll even draw you a schematic if you need it

Title 12. Health

A. The capacity of the tank. Based on the daily design flow, a minimum hydraulic detention duration of 48 hours should be implemented. It is not permitted to have a septic tank capacity of less than 750 gallons. Table 5.2 lists the septic tank capacity that are necessary for residential units at the bare minimum.

Table 5.2.Septic Tank Capacities for Dwelling Units.
No. of Bedrooms Approximate Tank Volume in Gallons
1 750
2 750
3 900
4 1200
5 1500

B. The tank’s physical dimensions. Septic tanks must be rectangular in shape in all three views: plan, cross-section, and longitudinal. The length to liquid depth to breadth ratio should be approximately equal to or more than 2 to 1 to 1 (2:1:1) and less than or equal to 3 to 1 to 1 (3:1:1), unless otherwise specified (3:1:1). The liquid depth must never be less than four feet or higher than eight feet in any circumstance. A minimum of one foot of free board must be given on each side. The tank’s inlet and outflow structures must be positioned parallel to the tank’s longitudinal axis.

Table 5.3.Typical Septic Tank Dimensions in Feet.
Approximate Gallons Length Width Liquid Depth Freeboard
750 7 3.5 4 1
900 8 4 4 1
1200 9 4.5 4 1
1500 9.5 5 4.7 1

C. The structure of the inlet and outflow. 1. A general statement. The inlet and outlet structures are intended to perform the function of a baffle. In order to accommodate the tank, the invert of the inlet structure must be larger than one inch but less than two inches higher than the invert of the outflow structure while both structures are in use together. Six to eight inches below, and eight to ten inches above, the typical liquid level, respectively, must be the length of the intake structure.

  1. The inlet and outlet structures must have an open area that is not less than four inches by four inches in cross-section or four inches in diameter, whichever is greater.
  2. All materials used in the construction of inlet and outlet structures must be resistant to chemical and electrolytic corrosion over an extended period of time.
  3. D.
  4. All septic tanks must be waterproof and equipped with a watertight top in order to function properly.
  5. When the septic tank has more than 30 inches of soil cover, an access manhole must be brought to within 18 inches of the ground surface and be equipped with a tight-fitting cover to prevent the septic tank from overflowing.
  6. E.
  7. Septic tanks must be designed and constructed by the contractor or manufacturer to resist the estimated lateral and bearing loads to which they will be subjected over the course of their operation.
  8. F.
  9. The tank must be positioned on a flat surface.

Whenever excavation is necessary, the hole must be large enough to accommodate the tank’s installation. Septic tank excavations must be backfilled in stages with appropriate tamping to prevent the soil from settling. There must be no huge stones or debris present in the backfill material.

How Sewer and Septic Systems Work

Many residents in rural regions who live in close proximity to one another and where a sewer system would be too expensive to create opt to build their own private sewage treatment facilities. Septic tanks are what these are referred to as. ­ It is a simple matter of digging up the yard and placing an enormous concrete or steel tank there to collect waste. The tank may have a capacity of 1,000 gallons (4,000 liters) of liquid. Wastewater enters the tank from one end and exits the tank from the other end of the tank.

  1. Anything that floats rises to the surface and produces a layer known as the scum layer on the surface of the water.
  2. In the middle, there is a layer of water that is relatively transparent.
  3. Wastewater enters the septic tank through the sewage lines in the home, as indicated in this illustration: Naturally occurring gases (generated by microorganisms breaking down the organic material in the wastewater) are produced by a septic tank, and these gases are not pleasant to smell.
  4. Instead, the gases rise through a vent pipe; if you look at the roof of any house, you will find one or more vent pipes sticking through.
  5. It is this water that drains from the septic tank and into the drain field.

Above is a schematic depicting an aerial perspective of a house, together with its septic tank, distribution box, and drain field: A typical drain field pipe has a diameter of 4 inches (10 centimeters) and is buried in a trench that is 4 to 6 feet (about 1.5 m) deep and 2 feet (0.6 m) broad, with a depth of 4 to 6 feet (about 1.5 m) and a width of 2 feet (0.6 m).

The amount of water that can be absorbed by the earth determines the size of the drain field.

In most cases, the only thing that powers a septic system is gravity.

It is a mechanism that is fully passive. “The grass is always greener on the other side of the septic tank,” you may have heard someone say. Actually, it’s the drain field, and the grass is indeed greener because it is taking use of the moisture and nutrients available in the drain field to thrive.
