What Type Of Septic Tank Did They Use 26 Years Ago? (Question)

When was the first septic tank made?

  • 1870 (estimated) – Mouras dismantles the tank. Surprisingly, it contains mostly liquid effluent and almost no solid waste. 1881 – Mouras is granted a patent for his septic tank design. 1883 – Septic systems start appearing throughout the US. 1940s – Septic systems become cheaper and more popular during the post-WWII economic boom.

What are old septic systems called?

The original pit remained as the part of the system that returned “clarified” wastewater to the ground. It now became known as a drywell. Sometimes due to heavy use, poor soil conditions, age of the system or a combination of these factors, the drywell still plugged up.

How does an old style septic tank work?

Septic tanks work by allowing waste to separate into three layers: solids, effluent and scum (see illustration above). The solids settle to the bottom, where microorganisms decompose them. The scum, composed of waste that’s lighter than water, floats on top.

How do I tell how old my septic tank is?

If you cannot find the septic system and know nothing about it or its history, start by checking the age of the building and its plumbing system with the premise that for most sites the septic tank and fields won’t be older than those.

What are old septic tanks made of?

Septic tanks are made from steel, concrete, fiberglass, or polyethylene. Steel tanks tend to rust, have a shorter service life, and are only found in older systems. Concrete tanks are durable, but occasionally can crack and leak wastewater.

How were old septic tanks made?

Many of the first septic tanks were concrete tanks that were formed out of wood and poured in place in the ground and covered with a concrete lid or often some type of lumber. In the 1960s, precast concrete tanks became more prevalent as the standard of practice improved.

What are the 3 types of septic systems?

Types of Septic Systems

  • Septic Tank.
  • Conventional System.
  • Chamber System.
  • Drip Distribution System.
  • Aerobic Treatment Unit.
  • Mound Systems.
  • Recirculating Sand Filter System.
  • Evapotranspiration System.

Can you have a septic tank without a leach field?

The waste from most septic tanks flows to a soakaway system or a drainage field. If your septic tank doesn’t have a drainage field or soakaway system, the waste water will instead flow through a sealed pipe and empty straight into a ditch or a local water course.

How long do septic tanks last?

A septic system’s lifespan should be anywhere from 15 to 40 years. How long the system lasts depends on a number of factors, including construction material, soil acidity, water table, maintenance practices, and several others.

Do septic tank additives really work?

There is little scientific data to suggest that you should add bacteria or enzymes to your septic system. The United States Environmental Protection Agency reported that biological additives do not appear to improve the performance of healthy septic tanks.

Do old septic tanks need to be registered?

Many homes are not connected to mains drainage, instead having sewage treatment systems or septic tanks or occasionally cesspools. If your sewage treatment system or septic tank discharges to a river or stream it must be registered immediately.

Can a septic system last forever?

How long does a septic system last? On average, a new septic system will last for 20-30 years. Soil quality – the quality of soil will determine how durable your septic tank is. For instance, acidic groundwater can corrode a concrete septic tank.

Do I need to replace my septic tank?

Under the new Environment Agency General Binding Rules, If you have a septic tank that discharges directly to a surface water (ditch, stream, river, etc.) you must replace or upgrade your septic tank treatment system to a full sewage treatment plant as soon as possible, or when you sell your property.

How old are metal septic tanks?

Steel septic tanks typically last 20-25 years, then rust, and collapse. Before this time steel baffles may rust off (damaging the drain field with sludge), the tank top may become rusty and unsafe, or the tank bottom may have rusted through.

What are the different types of septic tanks?

Septic Tank Types

  • Concrete. Concrete septic tanks. These durable tanks will usually last for several decades.
  • Steel. Steel septic tanks.
  • Fiberglass. Fiberglass septic tanks.
  • Plastic. Plastic septic tanks.
  • Aerobic. Aerobic septic tanks.

What are the signs that your septic tank is full?

Here are some of the most common warning signs that you have a full septic tank:

  • Your Drains Are Taking Forever.
  • Standing Water Over Your Septic Tank.
  • Bad Smells Coming From Your Yard.
  • You Hear Gurgling Water.
  • You Have A Sewage Backup.
  • How often should you empty your septic tank?

Septic System Age Determination

2018/05/25 Marie-Josée Raymond expressed herself as follows: Occupation of a residence at 3397 Kentucky Lane in Navan, Ontario. I’d want to know how old my septic tank and field are, please. This Q & A about the age of a septic system was first posted at The following is an index of SEPTIC SYSTEMS articles.

Reply:

Marie, Thank you for your outstanding question: how can I establish the age of my septic system, tank, and drainfields? I appreciate your help. While on the job, your septic contractor can examine the following components of your septic system: the septic tank access port, cleanout cover, tank material, pipe material (PVC, cast iron, terra cotta, ORANGEBURG PIPE), and the septic tank itself. septic tanks and lines In addition to the kind of plumbing, the materials used in septic tanks (steel, concrete, plastic, fiberglass, and home-made) provide date information.

  1. Leaning over (methane asphyxiation) or falling into a septic system both carry the danger of death.
  2. The life expectancy of a septic tank is mostly determined by the materials used in its construction, but the life expectancy of septic system pipe is largely determined by the likelihood of damage by vehicle traffic, root blockage, or flooding by groundwater.
  3. If you can’t identify the septic system and don’t know anything about it or its history, the first step is to determine the age of the building and its plumbing system, with the assumption that the septic tank and fields are not much older than the structure and plumbing system.
  4. If so, look atPLUMBING MATERIALSFIXTURE AGE.
  5. ORANGEBURG PIPE was originally utilized in Boston in 1865, although it was not employed in septic drain fields until the late 1940s and early 1960s, according to historical records.
  6. Check with your local building or health department to see whether any plans for your septic system have been submitted in the past, and if so, when.
  7. It is possible that the septic system drawings submitted as part of a permit procedure will not correctly depict the septic system that was ultimately completed, but you will be within the correct time frame.
  8. Website: (in French).
  9. Check see theSEPTIC TANK INSPECTION PROCEDUREAtCESSPOOL AGING ESTIMATES for more information on how to check a septic tank, including the tank’s location, size, type, materials, and overall condition.

Reader CommentsQ A

These nevertheless are made of something like clay and range in size from 12 to 18 inches in section. At the construction phase, they do not like to fit inside of one another; instead they butch up to one another and are covered with tar paper merely at the seams, which is why they are called “tar paper.” @Michelle, The Orangeburg pipe, which was a black perforated pipe that was utilized in septic drain fields, was what I believe you were referring to. Please refer to the app description for further information.

  • I’m curious as to what type of drain field makes use of 12 to 18 inch sections of pipe that are kept together with tar paper.
  • As an aside, I would want to point out that the size of the septic tank is inadequate by today’s standards, and the Orangeburg pipe that you describe is undoubtedly something that you would presume is no longer in working order.
  • Our house was once a cottage that was only sometimes utilized.
  • The piping that I can see is Orangeburg, and there is no distribution box; instead, there is a T approximately 6 feet away from the tank.
  • It just had two lines, in my opinion, because it was a modest home.
  • Given the age and character of the property, what are your thoughts?
  • For example, unlike some other items, septic tanks are not often date stamped, and they do not have a product ID code or data tag attached to them.

For example, you could come across plans for the installation of a septic system that have been filed.

What is the best way to determine the age of my septic tank?

If you fall in, you might suffer serious injuries or perhaps death.

The cover for a steel septic tank is generally readily pulled off by excavating slightly past the perimeter of the tank lid when it is in this location.

It is possible that it will need to be emptied and replaced.

As well as this, see WHERE CAN I FIND A SEPTIC TANK?

So far, this is what I’ve discovered.

Is this an entry point for the pump out system?

Is it necessary to add another access point?

There are two bedrooms and a bathroom in this tiny home.

I’d want to know when a house’s septic system and well water were installed.

According to Mark Cramer, a Tampa-based specialist, it all depends.

Best case scenario: fecal waste can be stored for decades in a sewage pit, seepage pit, cesspit, or outhouse due to the fact that it is extremely concentrated in one location with little to no oxygen, bacteria, or dilution.

In order to get more information, go to our article on SEPTIC CLEARANCE DISTANCES in theARTICLE INDEX.

Alternatively, it is likely that gravity was used to direct water to the d-box at the specified depth.

Hi: I recently discovered that the distribution box for my septic system is 6 feet below the surface of the ground.

Does this imply that the drain field is also far deeper under the surface than it would be otherwise?

Do you have any clue why the D-box and drain are buried so deep beneath the surface?

Please accept my thanks for your enlightening response; have a wonderful day.

In my opinion, you are possibly not paying attention to the essence of the matter, which is that any system that is that old would be deemed to be at or near the end of its anticipated life in any event, regardless of its age.

When it comes to buried components, I would anticipate your counsel to state that as long as the nature of what’s there is disclosed, you are not making any representations regarding their future utility.

Even if those do not reveal an immediate problem, if a system is tiny and old, and I were advising a buyer, I would advise them to budget for the possibility of having to replace the system in the future.

Very often, you’ll discover that what you’re concerned about is not what your consumer is concerned about at all.

My main worry is that I want to keep the number of residents as low as possible to avoid the septic tank overflowing during the sale of my property with owner financing.

For clarification, I contacted the local health department to see whether I could limit the number of individuals to three, and the response I received was as follows: Septic systems have traditionally been designed to accommodate two persons per bedroom.

What I’m wondering is, do you happen to know what the average size of a septic tank was in 1940?

Thank you so much for your assistance.

Is it possible for water from a strong rain or rising lake water to seep into a storage tank? How well are they protected from groundwater intrusion from the outside?

Question:septic system installation in Newfoundland, Canada lasted 60 years

(15th of May, 2014) Art Mercer recalled his involvement in the construction of a concrete septic tank for his family’s home in Newfoundland, Canada, in 1958 when he was 14 years old. With the help of 8″ pieces of aluminum piping, we dug a septic field behind the house (on rural land). This septic system has been in continuous service since that time (for more than 60 years), and it has never been closed or opened. It will be switched to the local town septic system later this week, by my brother (who was not even born at the time of the conversion).

Reply:

Thank you for informing me about your achievement, Art. In fact, there are several historic septic system drainfields that are still in use today. On a regular basis, I observe that soil qualities are critical to the efficient disposal of wastewater. As an example, in 1998, I dug a septic system that had been installed in 1920 but was still “working,” sustaining the residence of a single elderly inhabitant who had noticed odors surrounding the septic tank and reported them to me. We discovered that there was no drainfield or even a seepage hole where we were looking.

The effluent was disposed away, despite the fact that it had received very rudimentary treatment.

Question: 36 year old septic systems: contractor wants too much to do a repair

22nd of October, 2014) Sherry Lewis shared her experience, saying, “My septic system is 36 years old.” It is made of concrete (if the stand pipes are made of concrete, I assume the tank is as well), it has two tanks (the second is said to be an overflow tank), the soil in my area is mostly sandy (due to the proximity to the ocean), and I have lived in my house for approximately 30 years as the only occupant.

  • In addition, I only use the garbage disposal for the tiniest pieces of food that manage to find their way into it, and I don’t put anything else into the system other than water, soap, the tiniest amount of garbage trash, and toilet waste.
  • In the past, I phoned them because air was gushing out of my downstairs toilet and a buddy said that this meant danger as well as a full tank of gas.
  • The pumper man stated that, partly because of the system’s age, it was probably time to replace it, either completely or at the very least the leach field.
  • 2) When I spoke with a contractor about the task, he informed me that a lift station would be required owing to the high level of ground water (8′).
  • He recommended the lift station without visiting my home to measure the depth of my present sewage pipe, and I intend to contact him to confirm this rather than assume that they will not accommodate a standard system like the one I already have.
  • In the end, the gentleman who came to dig the test hole in order to determine the water level estimated an approximate cost of $7,000 or slightly more if I declared 4 instead of 3 bedrooms.

Because of the lift station, the contractor that will perform the replacement work has quoted a price that is nearly twice as much as the original estimate! That appears to be absurdly expensive! Please, someone assist me! Thank you so much for your assistance.

The Ins and Outs of Septic Systems in Pennsylvania

Septic systems on private land are used by approximately 26% of Pennsylvania houses for the treatment of domestic sewage. The majority of these residences also have their own private well for drinking water. If you have a septic system, be sure to operate it properly! If you understand how your system operates and how to maintain it, you will be able to do the following:

Septic systems on private land process the sewage of approximately 26% of Pennsylvania houses. The majority of these residences also have a private well for their drinking water supplies. If you have a septic system, you should be septic-savvy! If you understand how your system operates and how to maintain it, you will be able to do things like:

Who Has Oversight of Your Septic System?

In Pennsylvania, local governments (for example, boroughs and townships) are responsible for ensuring that private septic systems with a capacity of 10,000 gallons or less comply with Department of Environmental Protection (DEP) regulations. In the event that you have any queries regarding an existing septic system on your land, or about the construction of a new system on your property, you should contact your local government office first. Many towns have a Sewage Enforcement Officer who ensures that all septic systems are correctly sited, permitted, and inspected throughout their installation to verify that they follow all regulations.

Septic system maintenance is required by law in certain towns, and other municipalities maintain a sewage management program to ensure that property owners carry out this maintenance.

Soil Is Your Best Friend: How Your Septic System Operates

Not only does your household transmit human waste into your septic system, but it also sends all other liquid wastes into it, including bath water, kitchen and bathroom sink water, laundry water, and water softener backwash. Consequently, here’s what occurs underground when you flush the toilet, wash your clothes, use the sink or bath: The heavier solid stuff descends to the bottom of the septic tank, where microorganisms feed on the waste and break it down as a result of their activity. Fatty oils and greases that are lighter in weight float to the top of the tank, where they congeal to create a scum that may ultimately break down or be skimmed off during system maintenance.

  1. Disease-causing bacteria and viruses are present in the wastewater as it exits the tank, in addition to other impurities.
  2. Sewage travels through a pipe to a drainfield, which is a bed of gravel or other material used to collect the waste.
  3. Therefore, soil is the most significant component of a septic system because of its filtering abilities and the bacteria that it contains!
  4. Several factors influence the sort of septic system that may be installed, including the soil depth to bedrock or groundwater, how fast or slowly water travels through soil, and soil type and texture, to mention a few.

Keep Things Moving Underground

It is believed that the typical lifespan of a septic system is between 15 and 40 years, although it may live much longer if it is properly maintained. Maintaining your septic system is similar to changing the oil in your automobile. It is a low-cost investment compared to the high cost of constructing a new system, which may cost up to $15,000 and more. Don’t overburden the commode with your thoughts when you’re at the sink. Take into consideration what you flush down the toilet and down the sink.

It is best to avoid utilizing common household objects that might clog your system or kill the bacteria underground that are necessary for wastewater treatment.

  • D diapers, baby wipes (including those labeled as “flushable”), cat litter, cigarettes, coffee grounds, fats and grease, solids (including feminine hygiene items), and prophylactic devices are all examples of “system cloggers.” “TreatmentKillers” include household chemicals, gasoline, oil, pesticides, antifreeze, paint, and excessive concentrations of anti-bacterial soaps and detergents, among other things.

Don’t put too much pressure on your drain. The less water that you use, the less work your septic system needs to do to keep up with you. Use water-based appliances in small batches, install high-efficiency plumbing fittings, and address any leaks that may exist in your house. Protect your playing field. Keep anything that weighs more than your lawnmower away from your drainage field. Rain and surface water should be diverted away from it. Root clogging in the drainfield might cause the system to fail, therefore avoid planting trees or shrubs in close proximity to the drainfield.

It should be safeguarded and regularly inspected.

According to Pennsylvania laws, this should be done whenever the tank is more than one-third full of solids or scum.

Inspections and pumps may be required under the terms of your local sewage management program, which may be more strict.

For further information, contact the Sewage Enforcement Officer at the local government office where you live. It is important to be aware of the following warning signals of a failing septic system:

  1. Backing up or bubbling of wastewater into residential drains
  2. There is an unpleasant smell, or there is some black sludge surrounding the septic tank or drainfield. In the vicinity of your drainfield, you may notice bright green vegetation or spongy conditions.

If your sewage system is not operating properly, contact your local Sewage Enforcement Officer right away. It is important to respond quickly since the less pollution that occurs, as well as the lower the expense of repair work, the better. Your septic system will serve your house and contribute to the protection of Pennsylvania’s waterways for many years to come if it is operated and maintained properly. Do your part and learn about septic systems!

Types of Septic Systems

Septic system design and size can differ significantly from one neighborhood to the next, as well as throughout the country, due to a variety of variables. Household size, soil type, slope of the site, lot size, closeness to sensitive water bodies, weather conditions, and even municipal ordinances are all considerations to take into consideration. The following are 10 of the most often encountered septic system configurations. It should be noted that this is not an exhaustive list; there are several additional types of septic systems.

  • Septic Tank, Conventional System, Chamber System, Drip Distribution System, Aerobic Treatment Unit, Mound Systems, Recirculating Sand Filter System, Evapotranspiration System, Constructed Wetland System, Cluster / Community System, etc.

Septic Tank

This tank is underground and waterproof, and it was designed and built specifically for receiving and partially treating raw home sanitary wastewater. Generally speaking, heavy materials settle at or near the bottom of the tank, whereas greases and lighter solids float to the surface. The sediments are retained in the tank, while the wastewater is sent to the drainfield for further treatment and dispersion once it has been treated.

Conventional System

Septic tanks and trench or bed subsurface wastewater infiltration systems are two types of decentralized wastewater treatment systems (drainfield). When it comes to single-family homes and small businesses, a traditional septic system is the most common type of system. For decades, people have used a gravel/stone drainfield as a method of water drainage. The term is derived from the process of constructing the drainfield. A short underground trench made of stone or gravel collects wastewater from the septic tank in this configuration, which is commonly used.

Effluent filters through the stone and is further cleaned by microorganisms once it reaches the soil below the gravel/stone trench, which is located below the trench.

Chamber System

Gravelless drainfields have been regularly utilized in various states for more than 30 years and have evolved into a standard technology that has mostly replaced gravel systems. Various configurations are possible, including open-bottom chambers, pipe that has been clothed, and synthetic materials such as expanded polystyrene media. Gravelless systems can be constructed entirely of recycled materials, resulting in considerable reductions in carbon dioxide emissions during their lifetime. The chamber system is a type of gravelless system that can be used as an example.

The key advantage of the chamber system is the enhanced simplicity with which it can be delivered and built.

This sort of system is made up of a number of chambers that are connected to one another.

Wastewater is transported from the septic tank to the chambers through pipes. The wastewater comes into touch with the earth when it is contained within the chambers. The wastewater is treated by microbes that live on or near the soil.

Drip Distribution System

An effluent dispersal system such as the drip distribution system may be employed in a variety of drainfield configurations and is very versatile. In comparison to other distribution systems, the drip distribution system does not require a vast mound of dirt because the drip laterals are only placed into the top 6 to 12 inches of soil. In addition to requiring a big dosage tank after the sewage treatment plant to handle scheduled dose delivery of wastewater to drip absorption areas, the drip distribution system has one major disadvantage: it is more expensive.

Aerobic Treatment Unit

Aerobic Treatment Units (ATUs) are small-scale wastewater treatment facilities that employ many of the same procedures as a municipal sewage plant. An aerobic system adds oxygen to the treatment tank using a pump. When there is an increase in oxygen in the system, there is an increase in natural bacterial activity, which then offers extra treatment for nutrients in the effluent. It is possible that certain aerobic systems may additionally include a pretreatment tank as well as a final treatment tank that will include disinfection in order to further lower pathogen levels.

ATUs should be maintained on a regular basis during their service life.

Mound Systems

Unlike a municipal sewage plant, Aerobic Treatment Units (ATUs) employ many of the same procedures as that facility. When oxygen is introduced into the treatment tank, the system is known as an aerobic system. Due to the increased natural bacterial activity inside the system, the system is able to provide extra treatment for nutrients in the effluent as a result. It is possible that certain aerobic systems will additionally include a pretreatment tank as well as a final treatment tank that will include disinfection in order to further lower the pathogen levels.

ATUs should be subjected to routine life-cycle maintenance.

Recirculating Sand Filter System

Sand filter systems can be built either above or below ground, depending on the use. The effluent is discharged from the septic tank into a pump compartment. Afterwards, it is pushed into the sand filter. The sand filter is often made of PVC or a concrete box that is filled with a sand-like substance. The effluent is pushed through the pipes at the top of the filter under low pressure to the drain. As the effluent exits the pipelines, it is treated as it passes through the sand filtering system.

However, sand filters are more costly than a standard septic system because they provide a higher level of nutrient treatment and are thus better suited for areas with high water tables or that are adjacent to bodies of water.

Evapotranspiration System

Evaporative cooling systems feature drainfields that are one-of-a-kind. It is necessary to line the drainfield at the base of the evapotranspiration system with a waterproof material. Following the entry of the effluent into the drainfield, it evaporates into the atmosphere. At the same time, the sewage never filters into the soil and never enters groundwater, unlike other septic system designs. It is only in particular climatic circumstances that evapotranspiration systems are effective. The environment must be desert, with plenty of heat and sunshine, and no precipitation.

Constructed Wetland System

Construction of a manufactured wetland is intended to simulate the treatment processes that occur in natural wetland areas. Wastewater goes from the septic tank and into the wetland cell, where it is treated. Afterwards, the wastewater goes into the media, where it is cleaned by microorganisms, plants, and other media that eliminate pathogens and nutrients. Typically, a wetland cell is constructed with an impermeable liner, gravel and sand fill, and the necessary wetland plants, all of which must be capable of withstanding the constant saturation of the surrounding environment.

As wastewater travels through the wetland, it may escape the wetland and flow onto a drainfield, where it will undergo more wastewater treatment before being absorbed into the soil by bacteria.

Cluster / Community System

In certain cases, a decentralized wastewater treatment system is owned by a group of people and is responsible for collecting wastewater from two or more residences or buildings and transporting it to a treatment and dispersal system placed on a suitable location near the dwellings or buildings. Cluster systems are widespread in settings like rural subdivisions, where they may be found in large numbers.

How Long Will A Septic System Last?

Q:We recently purchased a home that had a septic system that was 20 years old. It’s a simple gravity system with a leach field at its heart. We had the system evaluated before purchasing it, and the inspectors stated that everything “appeared to be in good working order.” The vendors did not keep track of how many times they pumped the tank, although they claimed to have done it “a few times.” How long do you think we’ll be able to get out of this system before it needs repair or replacement?

— John et al.

Typical life spans in the business are 20 to 30 years for systems that have been adequately planned and built, have been well-maintained, and have not been overburdened with data.

I just had a conversation about this with a sanitary engineer who has been designing septic systems for more than four decades.

He has also encountered systems that have lasted 40 or more years, although they are the exception rather than the rule. During his presentation, he stressed that it is difficult to forecast the longevity of a single system. There are just too many factors to consider.

Don’t Forget Maintenance

Typically, the leach field is the first component to fail in a septic system system (drain field). The drain field is calculated based on the number of bedrooms in the house, with two persons sharing each bedroom. As a result, a three-bedroom drain field may accommodate up to six people. All else being equal, a drain field that receives little traffic will outlive one that receives a lot of traffic. In the case of a three-bedroom system, if only two people use it, low-flow fixtures and appliances are used, and the system is pumped on a regular basis, it should last for many years.

  1. Chemicals, grease, and food scraps that are flushed down the toilet will reduce the life of the system.
  2. The septic tank is the other main component of the system.
  3. Steel tanks often fail after 20 to 30 years, however high-quality plastic tanks can endure for 30 to 40 years with proper care.
  4. The lifespan of a system is influenced by a variety of factors.
  5. Others, like as proper care and upkeep, are completely within the hands of the homeowner.
  6. Routine pumping, household water conservation, and paying attention to what they flush down the drain — no harsh chemicals, paints, grease, food scraps, or other solids — are the most critical aspects that the homeowner can manage.
  7. Drainage of yard and roof water away from the drain field is necessary to prevent the soil from becoming saturated.
  8. Maintain a safe distance between trees and big bushes, as the roots of these plants might block the perforated drain pipes.

Replacement Cost

Drain field failure occurs gradually in the majority of cases when the soil around the leaching trenches becomes clogged with sediments and grease from the septic tank and becomes blocked by the naturally occurring “biomat.” In other circumstances, the drain field may collapse completely (due to high-volume water usage and inadequate pumping). Slow drainage, backups on the lower levels of the home, or moist regions over the leach field with a strong odor of sewage are all indicators of a clogged drain.

If the tank is in good condition and you have a designated area for a replacement drain field, as required in some jurisdictions, the cost of a new drain field will typically range from $3,000 to $10,000.

If you want a fully new system, the cost can easily approach $15,000, and if you require an alternate septic system, the cost can potentially reach double that amount.

The original drain field will have time to naturally heal once you begin using your replacement drain field, so it should be ready to be used when the replacement drain field is needed.

New Perc Test?

The majority of municipalities will require that you perform a fresh perc test and an in-hole test before they will issue a permit to replace your present leach field or full septic system. If a site has already passed the perc test, it is likely that it will pass again in the future. The opposite is sometimes true because site circumstances (for example, a higher water table) may have altered, or the town’s test processes and requirements may have changed. It’s possible that you’ll need to upgrade to a more expensive form of “alternative” septic system than the one you started with.

Perspective

When applying for a permit to replace your old leach field or full septic system, many towns will require you to undertake fresh perc tests and deep-hole tests. If a site has already passed the perc test, it is likely that it will pass again in the near future. The opposite is sometimes true because site circumstances (for example, a higher water table) may have altered, or the town’s testing techniques and standards may have changed. It’s possible that you’ll need to upgrade to a more expensive form of “alternative” septic system than the one you started off with initially.

Bay Restoration Fund

What is the Bay Restoration Fund (BRF) and how does it work? In 2004, Senate Bill 320 (Bay Restoration Fund) was passed and signed into law by President George W. Bush. The fund was formed by the Bay Restoration Fund. According to research, the water quality of the Chesapeake Bay has deteriorated as a result of an overabundance of nutrients in the water (mainly phosphorus andnitrogen). The top three significant producers of nutrients into the Bay are effluent from wastewater treatment facilities, household on-site(septic) disposal systems (OSDS), and agricultural operations.

  • Cover crop management, which reduces nitrogen loading into the Bay, is also supported by funds.
  • Each residence served by an onsite septic system is assessed a $60 yearly charge, which is collected from the homeowner.
  • Approximately 60% of the money are allocated for septic system repairs, with the remaining 40% allocated for cover crops.
  • If failing septic systems in Critical Areas are given top priority, monies can be allocated for the upgrade of existing systems to the best available technology (BAT) for nitrogen removal, rather than the more traditional technology now in use.
  • What are the benefits of upgrading our septic system?
  • Scientists have determined that nitrogen and phosphate contamination are the most serious risks to the Chesapeake Bay and its tributaries, according to their findings.
  • With the aid of the BRF grant, you may update your obsolete and ineffective septic tank with the Best Available Technology (BAT) and reduce nitrogen by at least 50%.

The nitrogen produced by everyone ultimately makes its way into the Bay or other rivers.

What is the operation of a nitrogen-reducing system?

The BAT units that are often utilized in Calvert County are designed to replace the traditional septic tank.

Nitrogen is released into the environment in the form of a harmless gas as a result of this activity.

The award is open to anybody who meets the requirements.

Those properties with failing or failed septic systems and those properties with metal septic tanks located in the Critical Area are given first consideration (that area within 1,000 feet of tidal watersof the Chesapeake Bay and its tributaries).

Grant awards are calculated based on household income in order to determine the proportion of the grant payment.

According to the Maryland Department of Environmental Protection’s Bay Restoration Fund, grant monies have been awarded to the Calvert County Health Department in order to pay for the BAT section of the septic system’s BAT component.

Property owners who make more than $300,000 per year, as well as any business, will only be eligible for half of the money for the BAT system installation, according to the government.

The subcontractors will be paid by the manufacturer when their task has been completed (electrical, plumbing, tank removal, installation, and othercosts).

What exactly does the grant cover?

If your property is not selected, the grant will pay for the pumping and filling or removal of your current septic tank, the installation of a new BAT system, the In what areas does the grant not provide coverage?

The following things will not be covered by the grant, and the property owner will be responsible for making the necessary payments:

  • Permit for the replacement of a septic system from the Health Department
  • A $60 recording fee is required in order for the agreement to be entered in the land records. The property owner is responsible for any additional expenditures associated with sewage disposal system repair or replacement that may be required in addition to those already listed above. Typical projects include the repair of defective drainfields, seepage pits, sand mounds, pump systems, and landscape restoration, among others
  • Electric service has been upgraded: In most cases, a dedicated 30 amp electric breaker (and perhaps more) is required
  • Otherwise, an upgrade may be necessary. Some of the other concerns that may occur during the installation process include: tree removal and excessive landscaping
  • Fence removal
  • And the removal of any walkways, decks, or patios that must be removed due to their proximity to the septic system. Repair of the system as a result of the owner’s negligence or misuse
  • The cost of power used to operate the system and the monitoring system on a daily basis Septic tank effluent pumping out on a regular basis
  • Maintenance and operation of the BAT system on an ongoing basis by a competent service provider after the first two-year contract has expired

What is the total cost of ownership and operation of the system? For further information about performance, please visit the Maryland Department of the Environment’s web site. What exactly is the procedure? The following is a list of terms that describe the grantapplication process:

  • Your application must be filed to the Calvert County Health Department
  • The house owner’s application is examined to ensure that it is accurate and complete. The property owner will be contacted or the application will be returned if more information is required by the staff. The homeowner must have their current system assessed by a certified inspector in order to identify the status of the existing system components and to confirm system failure in order to prioritize the repairs and replacements. It is necessary to apply for a sanitary construction permission prior to undertaking any percolation testing, and this permit must be obtained prior to the installation of the system. To obtain the permit, you must pay a charge of $175, which cannot be covered by BRF money. On all systems requiring replacement of the disposal component (drainfield), a percolation test will be required to be performed. Following the percolation test, this office will provide specifications in the form of a sanitary construction permit, which will be valid for one year. It is possible to utilize this information to seek cost quotes from competent septicinstallers for the portion of the project for which you will be responsible financially. Prior to receiving a grant, grant winners will need to come to an agreement with the Health Department. The property owner, as well as the Director of Environmental Health, will be required to sign this agreement before it can be implemented. The agreement will need to be documented in the Calvert County land records in order to be legally binding. A minor cost of $60 is required for recording
  • The homeowner must choose a BAT technology and enter into a contract with the seller of the chosen system before the recordation can be completed. It will be necessary for homeowners to review the ranking and evaluation information provided prior to making a decision on a BAT system. Additionally, the homeowner will need to enter into an agreement with a qualified septic installer for the portions of their project that are not covered by the BRF grant. Once all of the required paperwork have been received, an award notification will be sent to the homeowners, vendors, and installers. It will take 45 days for the vendor and installer to finish the installation process
  • Otherwise, the grant award will expire and no funding will be available for the project.

Can you tell me how long it will take to install the new system? A normal system will take between two and four days to complete. Residents will be allowed to use their waste water system throughout the whole duration of the project, with the exception of 3 to 4 hours during which the actual pipe hookups will take place. I have a lot of trees on my property; is this a problem? Barriers such as trees and other obstacles will be documented throughout the site inspection / evaluation process. If a tree or fence is in the way of a new system, it may be necessary to have it removed, with the expense of removal being the responsibility of the property owner.

Is it a concern that our septic tank is situated on a very steep slope?

It is possible that a composite tank, rather than a concrete tank, may be required due to the inability of huge machinery to reach steep slopes.

I feel my deck, sidewalk, and patio have encroached on my septic tank!

Deck, patio, and walkway replacement is the duty of the property owner (don’t forget to acquire a permit before demolishing and replacing the deck, patio, or walkway).

When will it be installed?

When a property is not originally picked, your application will be retained for three months before being ruled null and invalid if no further movement is made during that time period.

What should I do if I believe my system is about to fail?

I’ve been informed that I require a new drain field; would the grant be able to cover the cost of this?

Drainfields are eligible for financing under the BRF program for low-income applicants; but, due to the existing prioritizing process, we will not be able to pay any of those systems in the foreseeable future.

The frequency with which an inspection and maintenance are performed will vary depending on the type of equipment.

A maintenance agreement or service contract with a qualified contractor is necessary for the duration of the project.

Bleach, detergents, and other home chemicals should be used only when absolutely necessary.

If the service provider determines that it is required, pumping of the BAT system will be advised; however, pumping is not included in the original operation and maintenance contract and is the responsibility of the homeowner.

It is important for homeowners who have current water softeners in their houses to be aware that the wastewater from backwash cycles must not be permitted to discharge into a BAT system.

A trash disposal will have a detrimental effect on the operation of a septic system, right?

In order to avoid contamination of the aseptic system, it is strongly advised that you do not use a garbage disposal while disposing of sewage wastes.

The failure of the septic system is caused by the trash disposal releasing a finely ground mixture of solid debris into the septic tank, which will not entirely settle in the tank.

If you have food waste, it is advised that you COMPOSTappropriately.

What resources can I use to find out more information? The Maryland Department of the Environment has information about BAT systems, which may be viewed on their website. Alternatively, you may reach out to Steven Kullen at 410-535-3922.
