How To Install 275 Gallon Septic Tank With Distribution Box? (TOP 5 Tips)

Where is my septic system distribution box?

When finding the distribution box, it helps to have a general idea of where it sits. It makes sense that the box should sit between the septic tank and the septic drain field since it helps move the effluent from the tank into the field. It’s usually somewhere near the edge of your drain field on the end that’s closest to your septic tank.

How far down is the distribution box from septic tank?

It’s usually somewhere near the edge of your drain field on the end that’s closest to your septic tank. Distribution boxes are usually only about 6 inches to 2 feet deep.

Do you need a distribution box for septic?

The distribution box openings are often fitted with flow leveling devices that rotate. This is to make sure that the leach field lines are receiving an equal amount of wastewater. The distribution box is a major part of the septic system being able to function properly is very important.

Where is the distribution box in a septic system?

If your layout consists of a rectangular and level drain site, your distribution box is likely to be located near the edge of the drain field, closest to the septic tank. You can also look for a depression in the ground between the septic tank and drain field a couple of feet in diameter.

Can you pump septic from distribution box?

Your distribution box does not need to be pumped as your septic tank does. The distribution box will be down from the septic tank, close to the leach or drain field.

Can a distribution box get clogged?

One of the most common septic tank problems arises when the distribution box is damaged or clogged, preventing the flow of water from the septic tank into the drainfield. In most cases, a qualified plumber can fix this problem quickly and easily before it becomes a serious issue for the household septic tank system.

Does every leach field have a distribution box?

Distribution Box: Most, but not all, systems have a d-box. Once the effluent is separated in the septic tank, the distribution box, located in the leach field, dispenses the effluent into the leach field.

Should a distribution box be full of water?

A septic system distribution box should not be full of water. As effluent water leaves the septic tank towards the drain field, it first enters the distribution box. If the distribution box is full, there is a problem with clogged leach lines or a failing drain field.

Can you have a dishwasher if you have a septic tank?

DON’T. use your dishwasher, shower, washing machine and toilet at the same time. All the extra water will really strain your septic system. put items down your sink or toilet that can easily be thrown into the trash.

How deep should a distribution box be?

The D-box is normally not very deep, often between 6″ and two feet to the top of the box. You may also see a pattern of parallel depressions, typically about 5 feet apart, that mark the individual drainfield leach lines. The D-box will at or near end of the drainfield area that is closest to the septic tank.

How much does it cost to replace a distribution box on a septic system?

Septic Distribution Box Replacement Cost Replacing a septic distribution box costs between $500 and $1,500. This component is also called the D-box. It is very important, responsible for controlling the even distribution of wastewater into the leach field.

Does a distribution box have a lid?

Pre-cast concrete Distribution Boxes are sold usually by local septic tank and system suppliers and typically include gasketed openings for the effluent distribution pipe connections and a flat concrete lid that simply mates with the flat edges of the D-box without a gasket and without use of a sealer.

Does a septic tank always have water in it?

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).

What soap is safe for septic systems?

Whether you are handwashing dishes or using a dishwasher, these are safe choices:

Aldi Foaming Dish Soap.
Amway Home Dish Drops Automatic Dishwashing Powder.

Dropps Dishwasher Pods.
ECOS Dishmate Dish Soap.
Method Dish and Dishwasher Soaps.

Seventh Generation Dish Liquid.

Are garbage disposals bad for septic systems?

When you use a garbage disposal with a septic tank, the ground up food particles contribute to the layer of solids that is deposited on the bottom of your septic tank. There is no proof that these additives are useful, and in fact, they can be harmful to the delicate bacteria ecosystem in your septic tank.

How to Construct a Small Septic System

Documentation Download Documentation Download Documentation There are two main sections to most private septic systems: the holding and digesting tanks, and the dispersion field or leach field. As the liquid waste in the first holding tank fills up, it will be transferred to the second holding tank. Once the second tank is completely filled with liquid, the liquid will dissipate into the earth underneath it. The system displayed here is a modest system that is intended for limited use by two persons who do not need to do laundry.

When compared to a conventional house septic system, this system employs two 55 US gallon (210 L) drums, rather than the 1,000–2,000 US gallon (3,800–7,600 L) tanks that are utilized in a standard home septic system.

Property owners considering installing a system similar to this one should be advised that this system would fail inspections by any public health department in the United States, and that the owner may be liable to a fine if the system was discovered in operation by a health official.

Toilets that conserve water nowadays utilize less than two litres of water every flush.

It might be a lifeline for those who live in areas where septic treatment is not available.

Part 1 of 3: Cutting the Tanks

1Cut a hole in the center of the top of each drum that is the same size as the outer measurement of the toilet flange. Take the outside diameter of the toilet flange that you’re using and multiply it by two. Place the hole close to the edge of the drum so that you may simply connect them to pipes in the near future. Cut the drums using a saber saw to make them lighter
2 Each hole should be capped with a 4 in (10 cm) toilet flange. Push the flanges into the top of each tank until they are flush with the surface. As soon as the flanges are in position, tighten them down so they don’t move or shift once they are in place. Advertisement

s3 Cut a hole in the first drum that is 4 in (10 cm) in diameter on the opposite side of the drum from the hole in the top. Placing the hole approximately 4–5 inches (10–13 cm) below the top of the drum and ensuring that it lines up with the hole on the top of the tank are the most important steps. 4 Make a hole in the wall with a saber saw or a hole saw. Cut two holes in the side of the drum at 45-degree angles to the center of the hole on the top, one on each side of the drum. The center line is the line that runs through the middle of the hole on the top of the drum. Make 45-degree angles from either side of the centerline, then mark them on the second drum using a permanent marker. Make your holes in the barrel by cutting through the side with a saber or a hole saw and drilling them out. Advertisement

Part 2 of 3: Placing the Tanks Underground

1 Dig a trench that is 4 ft 26 ft 3 ft (1.22 m 7.92 m 0.91 m) in length and width. Excavator or shovel are both good options for digging a hole in the ground where you wish to put your tank. Continue excavating until the hole measures 4 feet (1.2 m) in width, 26 feet (7.9 m) in length, and 3 feet (0.91 m) in depth.

Excavators for excavating are often available for hire from a heavy machinery supply company. Look for equipment rentals on the internet

2Place the drum at the end of the trench, with one side hole drilled in it. When you place the drum on the floor, make sure it is level. Check to see sure the drum’s top is at least 4 inches (10 cm) below the surface of the water. 3 Dig a hole that is one foot (30 cm) deeper than the first to accommodate the positioning of the second drum in front of the first. In order to ensure a tight fit and prevent the drum from shifting, make your hole the same diameter as the drum you’re inserting in it. 4 The hole should be leveled with gravel until a 90-degree curve can be made to connect the top drum’s hole on one side to the toilet flange on the other. Check the alignment of the holes in the 90-degree bend between the two drums by dry fitting it between the two drums. If you need to improve the alignment of the pipe line, dig the hole a little deeper. 5 To make the bend, cut 31 2in (8.9 cm) pieces of ABS pipe and adhere them to the bend with epoxy or hot glue. With a hacksaw, cut the ABSpipe parts, also known as nipples. 6 Insert the pieces into the bend and hold them in place using PVC adhesive. Check the fit between the two drums to ensure that they are in alignment. Insert the end of the 21 2in (6.4 cm) nipple into the side hole of the first drum and tighten the nut. 7Glue the end of the 31 2in (8.9 cm) nipple into the toilet flange on the second tank, making sure that the nipple on the other end aligns with the hole on the top of the second drum. To hold the bent in place, apply PVC adhesive to the inside of the curve. Don’t be concerned about the link to the first drum just yet
You’ll make that connection later. 8. Glue a Y-bend to a 31 2in (8.9 cm) nipple, and then bend the angled piece of the Y-bend at a 45-degree angle. Using your PVC adhesive, attach a nipple to the end of the Y-bend and let it dry. Assemble the Y-bend and align the angled pipe on it so it meets the incoming waste line, then glue it onto the toilet flange. 9 21 2in (6.4 cm) nipples are cut and glued to one end of the 45-degree bends at the bottom of the lower drum, and they are then inserted into the side of the lower drum. Directional bends are defined as those that are perpendicular to the bottom of the trench at their ends. Advertisement

Part 3 of 3: Connecting the Drain Pipes

Put a stake into the ground and level it with the bottom of each of the 45-degree bends. 2Put a stake into the ground and level it with the top of the 45-degree bends. It doesn’t matter what sort of stakes you use since they all work. Use a mallet or hammer to pound the stakes into the ground. Attach a one-inch-wide block to the end of a four-foot-long (1.2-meter-long) level using duct tape. This will assist you in ensuring that you create sloped drain pipes so that your tanks can empty

3Place another stake approximately 37 8ft (1.2 m) down the trench from the first one
4Place another stake approximately 37 8ft (1.2 m) down the trench from the first one
5Place another stake approximately 37 8ft (1.2 m) down the trench from the first one. Drive the stake down until it is the same height as the first one using your hammer or mallet

4 Place the end of the level without the block on the first stake and the block on the second stake to complete the level without the block. Continue to pound the second stake into the ground until the level is balanced. 1 inch (2.5 cm) lower than the previous post, or 1 inch (0.64 cm) lower per 1 foot (30 cm)
5Repeat this method until you have stakes running the whole length of the trench
Continue to place stakes down the rest of the trench every 37 8feet (1.2 m) from the last one, ensuring that the stakes slope away from the drums

6Place gravel in the trench until the top of the gravel is level with the top of the stakes
7Place gravel in the trench until the top of the gravel is level with the top of the stakes The gravel will now slope away from the drums at a rate of 1 4 inch (0.64 cm) per 1 foot (30 cm) of horizontal distance
7Place 20 ft (6.1 m) of perforated drain pipe into each hole on the second drum

8Place 20 ft (6.1 m) of perforated drain pipe into each hole on the third drum
9Place 20 ft (6.1 m) of perforated drain pipe into each hole on the fourth drum
10P Insert the ends of the drain pipes into the 45-degree bends on the lower drum to complete the installation. 9Make certain that the perforations in the pipes are facing down so that liquids may soak back into the earth

8checking the pipes with a level to ensure that the 1 4in (0.64 cm) slope is consistent throughout the length of the pipe. Fill up any gaps in the slope by adding or removing gravel under the pipe. Seal the 45-degree and 90-degree bends that connect the lower and top drums, respectively, with silicone. For the greatest seal possible on your drain pipes, use a two-part epoxy or silicone caulk. For this purpose, consider utilizing flex pipe, which will yield a little bit if the ground changes. Tenth, fill the lower drum halfway with water to keep it from collapsing under the weight of all the gravel. Place the remaining gravel over the trench and into the bottom drum, covering it completely. 11Lay landscape fabric over the top of the gravel. As a result, the dirt will not be able to seep into the gravel and you will be able to keep proper drainage on your tanks
12Fill the remaining trench area with soil, compacting it to the original grade. When you have finished filling up the area with your dirt, check to see that the ground is level. 13Fill the upper drum with water, leaving the top pipe from the first tank exposed so that you can readily reach the tanks if you need to drain them later. 14Fill the lower drum with water. Fill the top drum with water and pour it directly down the exposed pipes on the bottom drum. Continue filling the drum until it is completely filled, then secure the top with a cap to keep out the elements. Advertisement

Community Q A

Create a new question

Question What is considered a low level of use? Low consumption is defined as less than 125 gallons per day. Question Was the ‘y’ elbow on the first tank’s tank for any particular reason? Is it left open or sealed when it has been completed? Isn’t it going to stink if it’s left open? The clean out requires a threaded cap or plug, which is provided. Question What kind of water do you use to fill it? “Fill” is the most important term here. Continue to fill the drum with water until the level does not rise any more
Question Suppose I neglected to attach a slip coupler to the perforated pipe and only had 10 feet of it. Is it still possible to use this? Yes, however you will need to raise the depth of the field in order to get the same cubic feet of capacity
Nevertheless Question What is the best way to find out if something is legal in my state? This is a quick and easy approach that is unlikely to be appropriate for long-term usage in the majority of states. It is possible that the property owner and/or the installation will be penalized if this is uncovered. Question Is it possible to utilize two or three 275-gallon water totes instead, or a water tote and barrel combination? It doesn’t matter either direction you go. It’s best to utilize a single tote and a barrel as a digestion tank and a distribution box if you have only one tote. Question What is the purpose of filling the higher barrel with water? You fill the top barrel with water so that when sewage waste is introduced into the barrel, it flows into a sufficient amount of water to initiate the anaerobic digestion process. Question What is the best way to clean up this system? If there is enough bacteria in it, it will clean itself with minimal effort. If it starts to fill up, you may call a septic service to have it emptied

If it doesn’t, you can do it yourself. Question What is the correct grade slope of the drain field for every ten feet of length of the drain field? It is possible for the field’s bottom to be level. When running away from the drums, the pipe system should be sloped at 2 percent, or 2.5 inches every 10 feet. Question Is it possible for this system to freeze in the winter? And might I use antifreeze in the mix as well? Antifreeze will destroy the beneficial bacteria that are required for the process to function properly. The process is biological, and it will generate some of its own heat as part of the process. It’s always possible to dig a little deeper to gain a little extra insulation above it.

The horizontal side of the “Y” links to the waste source, and it should be fitted with a connector that is compatible with the source supply line

Instead of using a 90° elbow, you should join two of them together to produce a U-shaped connection. In this manner, the end that is in the first barrel will be pointed towards the bottom of the tank, rather than the top. This should be reinforced with a short segment of straight pipe that is several inches deeper towards the bottom. Solids either float or sink depending on their density. They don’t seem to congregate in the middle. As a result, only the broken down liquid waste makes it to the second tank, and the solids are never seen again. The same procedure should be followed for each of the drainage pipes that originate from the second barrel. Just to be completely certain that no solids find their way into the global drain field, the waste is dumped into the first tank, with the solids settling to the bottom of the first tank. Whenever the liquid level exceeds the outfall to the second tank, it is drained into the tank below it. If there are any solids present, they will sink to the bottom. Whenever the liquid from the second tank reaches one of the two outfalls, it is transported to the gravel leaching field for dispersion. Over time, the vast majority of the solids will liquefy and disperse. Solids may accumulate at the top of the tank after many years, necessitating the removal of the solids. Thirty percent of the waste is absorbed into the earth, with the remaining seventy percent being dissipated by sunshine. It is important not to compress the soil since this would interfere with the evaporation process
The vertical side of the “Y” will be used to pump out the tank after it is entirely filled with solids
The depth of the trench should be proportional to the depth of the waste source line. If the line is deeper or higher than the one depicted, you will need to dig the trench deeper or shallower to suit the new line depth or height. It’s not that difficult to find out. In the event that you have a septic system that is too shallow, it may be more susceptible to damage. After a period, you may discover that the ground has sunk below the trench’s location. Fill it in with extra dirt and compact it

It is assumed that you are familiar with working with ABS plastic pipe. In addition, you must have the necessary tools to dig the trench (or be ready to put in a lot of effort).

Warnings

This is a system with a relatively limited capacity. This is not intended to suit the demands of a big family or group of people. It is intended for use with a modest travel trailer and two individuals. In order to extend the life of this little septic system, it is recommended that you do not place anything else in it but water, trash, and toilet paper. You may have to pump the upper drum once or twice a year if you don’t do so. During the course of five years, the system depicted here will only require pumping twice. Do not drive through the area where the drums are located. When establishing a septic system, make sure to adhere to all applicable municipal regulations. It is against the law to establish a septic system without first obtaining a permission. In the permission, you can find information on the local regulations for installing a septic system. You should avoid situating a septic system too close to trees since tree roots will grow into your lines, block them, and eventually cause damage to your system.

It is necessary to conduct percolation experiments in order to establish the soil’s absorptive capacity. All percolation tests must be carried out under the supervision of the Health Department on all properties where a private waste disposal system is required, including vacant lots. Laboratory testing on percolation shall be performed in the region that has been authorized by the authorizing authority. Tests shall be performed in sufficient numbers and at such places as indicated by the authorizing authority in order to ensure that the subsurface conditions can be reliably assessed.

Unless otherwise permitted by the authorizing authority, a soil percolation test is normally dug with a backhoe or other excavation equipment, and the results are recorded.
In this step, a description of the soil and an evaluation of the substratum conditions are documented, and the depth to which the time test may be done is decided.
(2)The percolation soil test hole should be made by excavating a hole one foot square by one foot deep on a ledge close to or on a ledge at the end of the observation pit and filling the hole with soil from the pit.

The soil test hole must be excavated in the porous absorption layer where the system is to be put, rather than in the surrounding soil.
The porous absorption area of the soil percolation test pit must be the only factor taken into consideration when determining the size of the system to be installed.
A soil description, including the identification of limiting horizons, and water level data have been collected, and the data suggests that the requisite treatment zone is present, and the site may be appropriate, before the test can be carried out.

Sand mound systems, grade mounds, and other shallow systems that require testing should all have single ring infiltrometer tests done on them as necessary.
D.Soil tests are performed.
The presoaking time for the first inch, which is regarded to be the presoaking period, must not be more than 20 minutes.

Only when employing inventive and alternative technologies can the percolation rate be increased.

In addition to the rate of water absorption, the usable area, other nearby failing percolation tests, the slope, the size of the initial system required, sufficient area for replacement systems, failing private systems in the vicinity, and other related factors are taken into account when determining a successful satisfactory soil test.

When the authorizing authority has information that the test findings are no longer reliable, or when the test protocols have been altered sufficiently to cause a major change in the results, percolation tests may be generally regarded invalid at any point in time.

If complete soil testing of a parcel of land reveals that the soil is not appropriate for a private waste disposal system, the authorizing authority may rule that the parcel is unsuitable for a private waste disposal system and refuse to do more soil testing on it.
(1) Prior to conducting a percolation test, the corners of the septic reserve zones must be staked.
The Health Department may need additional test pits for a site in order to ensure that the subsurface conditions can be accurately determined.

Any and all percolation test holes must be field identified and presented on a sealed (signed) plat by a professional engineer or surveyor.
The COMAR requires a minimum of one good preliminary percolation test per reserve area, with a maximum of three tests necessary per reserve area.
Without the express consent of the Health Department and until all applicable permits have been obtained by the Department of Public Works, Sediment Control Division, no grading is authorized in the septic reserve area or any area designated for on-site sewage disposal.

Any time sewage effluent from a single waste disposal system is to be discharged onto the surface of the ground or into the waters of the state, final approval of the proposal, including the issuance of a point of discharge, shall be subject to the policies of the Maryland State Department of Environmental Protection (MDSDEP).

They shall also provide the best technical guidance possible in an attempt to resolve existing pollution or public health problems, on a case-by-case basis, based on a case-by-case evaluation of each individual case.
When it comes to new building, alternative technologies can also be utilised.

In order for the suggested system to be effective as an alternative to the standard on-site sewage disposal system, the soil characteristics and ground water condition at the proposed site must exhibit sufficient support.
(1)When communal sewer facilities are not available and on-site repair is not practicable, the funds may be utilized for the re-construction of structures, provided that the structure was lawfully positioned and legally occupied within three years of the date of application.
A variation from the three-year restriction may be allowed on a case-by-case basis in the following circumstances: (a)The proposed construction will be used exclusively by the owner.

(c)The owner can establish that the property has previously secured permissions from the authorizing authority for an on-site sewage disposal system or holding tank on the property’s premises.
(2)Holding tanks must be large enough to store a minimum of seven days’ worth of effluent and constructed in a watertight manner.
On all holding tanks, an alert system for excessive effluent levels should be installed as a minimum.

(3)The applicant must submit with the application a maintenance contract that is acceptable to the approving authority, which must contain an appropriate pumping schedule between the applicant and a liquid waste hauler that has been approved by the approving authority.
When a contract is cancelled, the hauler and the property owner are jointly responsible for notifying the Health Department of the termination.

(4)The applicant and the authorizing authority must enter into a written agreement embodying the terms and conditions outlined above. The agreement will be transferred with the property and will be binding on any and all subsequent owners of the land.

How to Build a DIY Septic Tank System

You may install a septic tank system yourself to save money on the costs of hiring a professional septic designer and digger, which can add up quickly. Even if you design your own DIY septic tank and drainage system from scratch, the cost of installing a new septic system is high. Although it is possible to save money by establishing your own septic tank system, it is not recommended.

Costs of a DIY Septic System

The connection of a waste disposal system to a septic tank is critical for the health and cleanliness of the community. The installation of a septic system will be required if your property is located in an area where there is already no underground sewerage system. The public health fees for permits to construct a septic tank system are determined mostly by the county in which you live, but you will almost certainly be unable to avoid paying the permit charge. In order to establish the retail prices of yourDIY septic system design, which includes the drain field, distribution box, and pipes, you must first determine the price of the building supplies.

When shopping for hardware and home improvement supplies, compare prices amongst different establishments.

On top of that, you’ll have to consider about the excavation as well.

Before You Start Digging

Before you begin the actual building work, it is generally a good idea to do a thorough assessment of the situation. Get yourself a scale map of your home and property before you get your shovel out and start digging about in the dirt. The backyard, below the garage, or any side of the house that is near to a roadway are the greatest places to install a household septic system. The position of the septic system must be determined before any digging can begin. This is a very important phase in the process.

When installing a tank, it is vital that it is done right the first time.

The Site Evaluation

In most jurisdictions, the old perc test has been replaced by a site evaluation as a means of demonstrating to your local health authority the treatment characteristics of your property’s infrastructure.

DIY Perc Testing

In the past, the perc test was performed by simply dumping a pail of water into a tiny hole in the ground and then timed how quickly the water soaked into the soil with a stop-watch. The site inspection is carried out at the bottom of a 6-foot-deep trench. Unlike the perc test, which only measures the absorption speed of a small section of the property, the site evaluation measures the absorption speed of a much larger region over the soil face.

Soil Classification

The Soil Conservation Classification System of the United States Department of Agriculture is the soil classification system that is utilized in practically all states in the United States today.

As you continue to examine down into the earth, you will see that most soil testing pits include three or more different types of soil.

Drainfield Trench Size

This does not affect the size of the drainfield, which is independent of the number of bathrooms or fixtures on the property. Almost all health departments employ the following methods to determine the flow rate:

An individual’s residence’s total number of bedrooms The amount of persons that are present in the residence
Water use on a daily basis

The volume of sewage that must be discharged into the drainfield is determined by the flow rate. Once you have determined the kind of soil under your prospective drainfield, use the table shown here to calculate the drainfield area necessary for your house size, and you will have the drainfield size you require.

Size of The Septic Tank

The size of a septic tank construction is decided by the number of people living in the home or on the land for which it is being built. Consult the metric standards for the area in which the construction is to take place before proceeding. This is the most accurate method of determining the amount of septic tank you should use when constructing your own septic tank system. The size of your DIY septic system will also decide how frequently you will need to have your DIY septic system pumped by a professional septic pumping service, which will be determined by the size of your septic system.

Creating the Drawings

Before we can begin construction on our septic system, we must first develop the necessary designs to fulfill the requirements of your local health authority. Your DIY septic system designs may need to be more detailed than you think they need be, depending on your state’s requirements. All structures, pathways, property borders, retaining walls, and the position of the original test holes, on the other hand, must be clearly depicted.

Drainfield Layout

Your drainfield plan will necessitate the construction of a minimum of two ditches of similar size. The division of the water flow into two, three, or more lines is performed by using a distribution box, also known as a D-box, to split the flow. It is used in the distribution box to distribute water through pipes that include flow control valves in the form of eccentric plugs that distribute the water evenly across several drain lines. The effluent must travel downhill from the tank outlet, past the distribution box, and down the individual trenches before being disposed of.

Apply for a Building Permit

Now that you have the drawing, you should submit your ideas to the local health department’s office for consideration. You will be required to complete an application form as well as pay the applicable permission cost. Following that, you will need to wait for the designs to be examined and authorized by the board of directors before moving on to the final construction phase of the project.

Building a Septic Tank System

To begin the construction process, the first step is to sketch up a rough schematic of the septic system. You’ll utilize this layout to put your construction designs into action on the ground. It is necessary to project the layout and position of all of the different components of the septic design onto the site.

Excavation of the Septic Tank System

When it comes to digging the site in order to prepare for the construction of the septic tank and drain lines, it is important to pay close attention to elevation in order to get the best possible results. The health inspector will need to inspect the job one more time after you have finished all of the excavation before you can begin backfilling.

Once you have finished all of the excavating, you will need to schedule another appointment with him for a final inspection of the job before you can begin backfilling.

Backfilling the Septic Tank System

During the building process, all of the tanks, pipelines, and vaults should be backfilled around the perimeter. Your local authority may mandate that all tanks be subjected to vacuum testing, pressure testing, or water testing. Aside from that, an increasing number of counties are demanding leak testing of the tank these days. Consequently, the final backfilling of the concrete tanks can be delayed until after the final inspection to check for leaks has been completed. The final backfilling should not be completed until after the final health department inspection has been completed.
