Overview of the septic tank "DKS": what stands out in the septic tank market among other options?

The principle of operation of septic tanks

The septic tank consists of three chambers - two sedimentation tanks and a biofilter.Sewer water through the pipe first enters the first sump - here, by separating into heavy and light elements, the first purification takes place: the heavy ones settle to the bottom, forming a silt sediment, and the lighter ones remain on the surface and go for further processing. The settling tanks are interconnected by means of an overflow pipe, which is located in such a way that partially clarified liquid enters the next chamber, and the sediment remains at the bottom - here additional settling and sedimentation of smaller particles take place. At the same time, in two settling tanks, wastewater is decomposed by anaerobic bacteria in an environment without air access, which is observed with hermetically closed hatches.

Wastewater enters here purified by a maximum of 2/3 and is subjected to biological treatment. The biofilter includes a supply pipe, a sprinkler and a so-called brush load, on the surface of which there are aerobic bacteria that can process and decompose organic impurities. Oxygen, necessary for the life of microorganisms, enters the middle of the compartment through the ventilation pipe.

Before buying this or that septic tank, you should consult with the seller

Work in the drive:

1. Further, the purified water enters the drive, which is included in the package of models, in the name of which there is the letter "M".
2. This accumulator contains a float sensor, which is triggered when the tank is filled to a predetermined level, and the drainage pump is turned on, which pumps water to the drain into the well or drainage ditches.
3. Conventional models do not have such a drive, and the liquid is immediately discharged through the drainage system into the soil or well.

It is necessary to clean the septic tank from silt approximately once a year using a fecal pump or use a sewer machine every two years. And the place for its installation must be chosen so that the machine for pumping out sludge can drive up.

Zuzako editorial recommendations for choosing a septic tank for a country house and a summer residence

On sale you can find a huge number of different models, differing not only in cost, but also in parameters. For the right choice, many nuances should be taken into account.

Remarkable! For a site with hard ground, it is best to choose a horizontal septic tank, which requires a shallow pit.

Inexpensive septic tank

Even with a small budget in reserve, you can find a good septic tank with decent performance.

It is important to pay attention to several key parameters. The main thing is performance. In order for the septic tank to really effectively cope with its “duties”, you need to rely on a simple formula: each person living in the house consumes about 200 liters of water per day

Moreover, if the house has a bathtub that involves a volley flow of a large amount of water, you need to choose a device with a capacious receiving chamber

In order for the septic tank to really effectively cope with its “duties”, you need to rely on a simple formula: each person living in the house consumes about 200 liters of water per day. Moreover, if the house has a bathtub that involves a volley flow of a large amount of water, you need to choose a device with a capacious receiving chamber.

In addition, it must be taken into account that open-bottom clarifiers can only be used in soils with good carrying capacity and in low groundwater.

Autonomous septic tank

If power outages often occur on your site, give preference to an autonomous septic tank. Moreover, it has many advantages.

• More affordable price compared to volatile units.
• Usually shows great durability and reliability.
• Its work does not depend on the availability of power.
• Does not create additional energy costs.

But, choosing such a device, do not forget about its shortcomings.

• Often, autonomous septic tanks do not completely eliminate the unpleasant odor.
• The gradual accumulation of sludge requires regular pumping.
• With such a sump, you should take care of access roads for sewage trucks.
• Groundwater filtration is required.

In addition, it should be understood that an autonomous septic tank requires a larger area for installation.

Energy-dependent septic tank

Network-operated units are considered more powerful and productive. If you do not have problems with electricity, opt for a volatile septic tank. It also has many advantages.

• They do not collect precipitation.
• They can be moved to any convenient place.
• Guarantees complete isolation of an unpleasant smell.
• Do not require installation of filtration fields.

But it was not without drawbacks, which should also be taken into account.

• They have a higher cost.
• Dependent on electricity.
• Less reliable than standalone models.

When choosing a suitable device, be sure to check whether it is able to work during an emergency power outage. On the market, you can find septic tanks that can continue cleaning even without offline power.

Operating principle

Technically, two types of waste disposal are used: anaerobic (without air access) and aerobic (decomposition involving bacteria that need oxygen for life).

Septic tanks have an anaerobic mechanism of action, which act as a storage tank or sump. Such purification systems, without installing additional equipment, carry out only primary clarification of wastewater and require their frequent pumping by a sewage machine.

This option is suitable for rarely visited cottages. or private houses with a small number of inhabitants. The cost of such a structure is low, the installation does not require much effort, and the operation does not require a constant flow of effluents into the chambers.

The principle of operation of an anaerobic septic tank

Often colonies of active bacteria are added to such septic tanks, which help to filter effluents better than with conventional anaerobic treatment.

The aerobic mechanism of action is carried out by local purification stations of biological action. In such septic tanks colonies of aerobic bacteria are settled, which effectively purify wastewater.

For the normal functioning of these septic tanks, the installation of aerators is required, which will supply the oxygen necessary for the vital activity of bacteria. Also, aerobic systems must constantly work - if within 2-3 weeks there is no new effluent entering the chamber, then the bacteria will die and their cultures will have to be planted again.

Obviously, the best septic tank for a country house is aerobic. But it all depends on the budget, as this type of treatment plant is more expensive.

Scheme of operation of a septic tank for aerobic treatment

Septic tanks for cottages

Depending on the frequency of use and the volume of incoming wastewater, septic tanks are of three types: for a country house, for cottages and cottages. In this article, we will take a closer look at the latest version of the cleaning system.

Advantages of sewerage equipment:

• Without smell
• Eco-friendly and meets all standards
• Year-round operation
• Service life up to 50 years
• Completely non-volatile
• Minimum operating costs

The mechanism of operation of a septic tank for cottages

A similar type of septic tank is a plastic tank, divided into three containers, interconnected by a pipeline. At the joints on top of the pipes there are locks designed to enhance the process of sedimentation of heavy elements of wastewater. Each department has its own purification stage, which ultimately gives up to 80% water purity. After the septic tank, the effluent enters the filtration or absorbent area for further purification.

How to choose and install a septic tank for cottages

When the question arises which septic tank to choose, the following factors must be taken into account: the number of permanently residing family members, the average daily water consumption per person, as well as the number of household appliances that use liquid (washing machine, dishwasher). Having calculated and selected the required volume of a septic tank for a cottage, you can buy it in St. Petersburg and other cities.

After the acquisition, it is worth making sure that the tank is intact, and also, before installing it, clarify in the reference literature what type of soil is in the region of your residence.With a close passage of groundwater to the ground level, it is advisable to lay a concrete slab under the tank, securing them together with anchor straps. Then it is necessary to prepare a pit according to the following requirements: the bottom is tamped with a layer of sand (about 30 cm), having installed a septic tank, sand is also poured around it in layers of 50 cm thick, while actively tamping. At the end, the septic tank for the cottage is again covered with sand from above by about 30-50 cm. Before starting operation, the tank is filled with water.

If you want the cleaning system to serve with high quality and for a long time, once a year it is necessary to call the cesspool equipment to clean the tank from all sludge. This fact requires the land owner to provide a convenient car access to the sewer manhole.

Three of the best volatile autonomous sewers

An aerobic septic tank needs a constant connection to the mains, a compressor and hydraulic pumps. Electricity for operation is necessary by definition. Only with a continuous supply of air, aerobes absorb organic matter at the proper rate. It is this autonomous sewage system that is a full-fledged deep biological treatment station.

"BIODEKA" - minimalist design with maximum performance

The operation of the BIODEK septic tank is based on the treatment of wastewater with suspended sludge, in which aerobes live.In general, the installation is a classic aerobic station, but the developers managed to place all the working chambers and units in a single cylindrical housing made of foamed polyethylene. The result is a light, cheap and strong structure weighing up to 150 kg.

The cylindrical body of the septic tank "BIODEKA"

BIODEKA works according to the scheme in one cycle, which made it possible to get rid of an extra compressor and expensive automation. At the same time, the remaining aerator and pump are constantly involved, reducing the risk of airlift overgrowth to a minimum.

"TOPAS" - reliability of aerobic technology

Reliable septic tank Topass low power consumption clears drains by 99%. This is a classic system with two cleaning cycles. First, the sewage masses enter the primary chamber, where solid waste is filtered out. Then they enter containers with anaerobic microorganisms, which break down all the organic matter contained in them.

Topas modifications depending on the depth of the sewer pipe supply from the house

Models differ not only in performance, but also in the level of penetration of the sewer pipe. The removal of treated wastewater from the TOPAS septic tank is carried out by gravity or forcibly using a drainage pump.

UNILOS is the best option for harsh Russian conditions

Another classic among septic tanks is the UNILOS station. Two types of purification (mechanical and active-biological) guarantee a high degree of water purification. First, mechanical impurities are removed from the effluents, and the remaining organic contaminants are eaten by aerobes.

Autonomous sewerage device "Unilos"

The design provides for possible interruptions in the power supply. The system is also resistant to power surges.Another feature is the ability to manually remove accumulated sludge. In many other septic tanks, this can only be done using the built-in pump.

Rating of septic tanks for a country house

The main characteristics of septic tanks for a private house are the following parameters:

• Capacity. A wide range of sizes of septic tanks is one of the main needs of modern homeowners;
• Resistance to negative external factors. Temperature changes, high pressure, spring rise in groundwater can affect not only the operation of the septic tank, but also its integrity;
• The material from which the tank is made. For the production of septic tanks, foamed polystyrene is most often used. But they can also be made from cross-linked plastics, metal alloys, and many other materials;
• Energy independence. For a private house and a summer residence, it is much more convenient to use a container that does not depend on the local electrical circuit;
• Dimensions. A compact septic tank is suitable for installation on a plot of non-standard shape or simply installation in a country house with a small yard. Large systems are becoming less and less preferred, giving way to small waste tanks;
• Affordable cost.

According to reviews on construction forums, the Tank septic tank tops this rating. It exemplifies the perfect combination of compact size and strength. At the same time, the price of the device is lower than some other representatives of this market. There are also no complaints about the durability and efficiency of this drain. Due to the stiffening ribs that permeate the entire body of the system, the "Tank" copes well with pressure drops and high groundwater.

Septic Tank

Topas is in second place in popularity. It is ideal for cesspools of country houses. During the day, this compact system is able to process more than 20 liters of waste, which is almost 2 times more than its counterparts. Depending on the needs, vertical and horizontal placement is possible.

Vertical septic tank Topas

Triton is a high-quality deep cleaning septic tank. The manufacturer produces the system in several modifications: mini, medium and maxi. The size and capacity is chosen based on the size of the family and the needs of the homeowner. Another feature of this biological treatment plant is durability. "Triton" is made of a dense layer of cross-linked plastic. It does not give in to corrosion and maintains differences of temperature to 20 degrees.

In fourth place on the list is the cheapest of all the listed models - the DKS septic tank. Its cost makes it an unrivaled wastewater treatment plant. Of course, it is significantly inferior to "Tank" and "Topas" in terms of filtering, but it requires less investment. It is made of plastic casting methods.

Septic tank

At this point, the rating can be considered complete, since the remaining wastewater treatment systems are approximately equally popular. In addition, homeowners often confuse storage and treatment systems, which is why simple settling tanks fall into the list of septic tanks.

Features of the septic tank DKS

The DKS septic tank is made of polypropylene - thanks to this factor, the systems are light in weight and are sold at a reasonable price. This allows you to create an uncomplicated transportation of the system to its destinations.

The table shows the models of septic tanks DKS.

The most reputable manufacturers of wastewater treatment systems

In order to correctly determine which septic tank is better, you must also take into account the company that manufactured this model. To date, the operation of water purifiers of such domestic companies as City Eco Plast, Helix, Rosecology, Topas, Bioksi, Aqua has earned the recognition of customers.

Users have appreciated the high quality and easy maintenance of these cleaning systems. For work use only environmentally approved drainage agent. The purchased domestic product for wastewater treatment will have standards for its work according to international and domestic standards SapPin and GOST, as well as taking into account the peculiarities of the Russian climate. So, the Russian septic tank will be better than the Western counterpart. It is such a wastewater treatment plant for a summer residence that is good, it will serve for a long time and regularly.

Rating of septic tanks

In the variety of possible septic tanks and their variations, it is very difficult to choose which system is best to install in your country house. First of all, it is worth determining which principle of operation suits you best from 2 categories, non-volatile or volatile, and then choose the best from this category. This rating presents separately the best non-volatile models and separately the best non-volatile models. Before deciding check the groundwater level on your site, are there water protection facilities nearby, is there enough space on the site for an additional wastewater filtration device.These are all the criteria by which the possibility of installing a non-volatile septic tank is determined, if according to these criteria this option does not suit you, then choose immediately from the group of non-volatile septic tanks.

Septic tank Triton mini

The emergence of this septic tank model is due to the increasing demand for small sewage treatment plants. station for giving. With its small overall dimensions, it has good performance characteristics.

This model is based on the principle of the impact of natural anaerobic bacteria on wastewater.

Getting into the receiving chamber, they partially decompose, as a result of which a layer of activated sludge begins to form.

Further, with the help of the overflow channel, the clarified liquid enters the additional purification chamber, where the residual contaminants finally disintegrate into its constituent elements.

For the latter option, the manufacturer offers special plastic drives. The body of the treatment plant is made of polymer materials, which significantly affected its low weight.

Characteristics:

• designed to serve a maximum of 2 people;
• usable volume - 400l;
• productivity - 500 l / day.

Features easy installation and maintenance.

Instructions for use

After installing the septic tank, it will take some time for the number of anaerobic bacteria to increase to the required level. Until then, the quality of water purification will be lower.

Important! Therefore, it is recommended in the first 2-3 days to drain the effluent from the septic tank into a storage tank. Triton septic installation mini

Further operation of the device is not difficult.The main thing is to follow simple rules:

• it is forbidden to dump rotten food residues, medicines and chemically hazardous liquids into the sewer;
• it is also impossible to dispose of polyethylene, pieces of cloth and other similar garbage that can lead to blockages;
• engine oil, gasoline, diesel fuel and antifreeze will significantly impair the operation of the station.

In order for the operation of the septic tank to be stable, it is necessary to visually check the composition of wastewater once every three days. As activated sludge accumulates, remove its excess.

To do this, use the services of a sewer machine. The average frequency of this procedure is once a year. At the same time, the walls of the septic tank should be thoroughly washed after pumping out.

2 Biofor 0.9 Profi

Continues the category of budget septic tanks Biofor 0.9 Profi. This model will be an excellent solution for a summer cottage. The tank is designed to serve two users at the rate of 200 liters per person per day. The total volume of the septic tank is 900 liters. It is completely non-volatile, which means it is available for installation in any area with one condition - the groundwater level must be low.

The septic tank does not need regular pumping, but once every few years the services of a sewage truck will still be needed, it is necessary to pump out the accumulated sludge. The tank body itself has a unique geometry that can withstand significant ground pressure. The bottom in the form of a pallet prevents the compaction of sludge and allows you to fully pump it out. Biofor 0.9 Profi is easy to install, even a layman can easily handle it. Among the disadvantages: low degree of purification, water requires additional filtration.

How to choose the best septic tank for a private house: Topas or Tank - expert recommendations

How to choose the best septic tank for a private house: Topas or Tank and use them to create a comfortable life in the country, if there is no centralized sewerage? The answer is simple and clear: in order to choose the right water purifier for a summer residence, you need to know their technical and operational capabilities.

Domestic and global manufacturers of water treatment systems offer a sufficient number of filtration technologies for the removal and disposal of wastewater. But, in all this variety, how to buy the right wastewater treatment system and install it? We offer a brief description of the actual performance and features of the most popular models of cleaners.

Basic rules for the maintenance of these installations

Initially, the structure was designed for the owner to be able to independently serve it. Special knowledge or the help of specialists is not needed for this.

Proper use of a septic tank begins with its installation. The diagram shows how best to install and secure the structure in the ground

So, the system will work for a long time and efficiently if you regularly perform the following actions:

• about once a month, lift the lid and inspect the device in order to check the transparency of the water and the presence of a smell;
• control sedimentation at the drain point;
• pump out sludge once every six months;
• renew the compressor membrane every 3-4 years.

The video will help you familiarize yourself with the process of removing sludge.

Waste sludge is used in the beds or in the garden as fertilizer. It is absolutely safe, disinfected, and also prevents the development of parasites and pathogens. At one time, you can pump out about 200 liters of sludge, which is placed in a compost pit or on beds.

Topas system

A device called Topas also claims a place in the ranking of the best septic tanks for a country house. Moreover, it is he who is one of the leaders in the market of treatment systems. A feature of this device is the use of living microorganisms for wastewater treatment.

Several sectors through which waste flows provide 98% pure water at the outlet. The principle of operation of the station is as follows: initially, the effluents enter the sump, where they remain until they rise to a certain level. At this level, there is a float, when triggered, the liquid moves with the help of a compressor to sector number two.

Anaerobic bacteria live in the second compartment, thanks to which all the pollution that got along with the water after sector number one is destroyed. In sector number three, the water is stratified into silt, which precipitates and purified water, which follows into compartment number four, where it exits through the outlet.

As a result of the operation of the Topas treatment system, purified industrial water and fertilizer in the form of sludge are obtained. The competitive advantage of this installation is the use of colonies of microorganisms in it, due to which stagnation and decay of wastewater in the middle of the septic tank is excluded. There is no need to separately acquire bacteria - they live in sufficient quantities in water and in the environment and enter the system without hindrance. Also, during operation, the septic tank does not produce noise and vibrations.

Features of each system

If we compare septic tanks for a country house, starting from the price category, then Tank and Tver will be the most budget options. The most expensive device is Topas.

Tank and Topas received the most positive feedback from consumers. In addition to these systems, Mole, Aspen and Breeze are also popular on the market. All of them are approximately in the same price category and have equal technical characteristics.

Cleaning systems on the market are represented by a fairly large assortment, therefore when choosing a septic tank The best solution is to take the advice of professionals. Their assessment of soil features, groundwater level and landscape structure will help to choose the right cleaning system with a certain productivity and technical characteristics, as well as fit into the allotted budget for the installation of the station.

Do not forget about the volume of water consumed in order to choose exactly the model that will most effectively cope with wastewater treatment in the shortest possible time. Installing a septic tank of the right size and modification is the key to the effective operation of the system.

Volatile septic tanks

This equipment requires a permanent connection to the mains. Its work is based on forced aerobic wastewater treatment. Energy-dependent septic tanks are a station that performs deep purification to a level where wastewater can be used for irrigation, draining into ditches and water bodies without negative consequences for the environment.

To date, the most popular models are:

Tver is a local septic tank that provides comprehensive wastewater treatment. The equipment uses several different cleaning technologies, which together provide a brilliant result.The device is suitable for use in permanent residences, but seasonal use is also acceptable, provided that the recommendations for equipment conservation are observed.

Installation of the unit is carried out on any type of soil, including peat, which are characterized by increased aggressiveness. Durable, practical plastic is resistant to corrosion processes, and the use of an “anchor”, which is installed in the pit, fixes the container well.

A feature of Tver is the ability to receive water in large volumes.

In the septic tank Leader, due to electricity, the sediment is removed from the sump and the aerator is turned on. necessary to enrich the water flow with air in order to multiply aerobic bacteria that process organic matter. The complex, consisting of six chambers, does not require the use of biological additives and is resistant to sewage pollution. The recycled water can subsequently be discharged into reservoirs, drain wells or ditches.

The Poplar septic tank can operate in a wide range of ambient temperatures. Its operation is based on step-by-step purification of effluents passing through four chambers. Two of them use aerators. Oxygen is injected under the influence of compressors, and the flow is circulated using airlifts. The service life of the equipment reaches 50 years.

Wastewater treatment through the Topas septic tank is carried out in several stages - decomposition of organic matter; reduction of the concentration of minerals in wastewater and purification from mechanical components. This approach allows you to get 98% purified water at the output, which will be used later for irrigation of a personal plot.

Ecopan is suitable for use on heaving soils containing clay.

Septic Unilos produces biological and mechanical wastewater treatment. It can work under the condition of power outages.

The Yunbas septic tank performs cyclic wastewater treatment. The repetition of the same processes provides a brilliant result.

Choosing the best septic tank

According to experts and owners of septic tanks, the best models for wastewater treatment are Tank (among non-volatile septic tanks) and Topas (among volatile ones).

Description of popular models

The DKS-15 model is capable of treat up to 450 liters of wastewater per day, designed for installation at a low level of groundwater, in dry soil. The septic tank is designed to use the toilet, shower, sink, dishwasher and washing machine and does not require power connection. This model is also available in a variation with the letter “M” - DKS-15 M. This device is additionally equipped with a drainage pump, and it can be installed in a site with high groundwater. These models are designed to serve 3-4 users.

Other Models:

1. The DKS-25 model is capable of processing up to 750 liters of waste per day and is designed for 5-7 people. Resistant to temperature changes.
2. The septic tank DKS-25 M can be operated on a site with a high level of water occurrence.
3. If you plan to be in the country only on weekends, then the DKS Mini septic tank is suitable - it is small in size and has a capacity of about 120 liters of waste per day. This model can also be used as an additional septic tank for a guest house or bath.
4. Model optimum (or optimum) - cleaning performance is not more than 250 liters per day. This model is recommended for sites with seasonal residence.

The septic tank of the DCS has a fairly large size

They produce "Country sewer systems" and local treatment facilities - MBO, in which not only deep biological treatment takes place, but also disinfection of sewage water. Such a station is powered by electricity, and if it is impossible to connect to electricity, work is carried out according to the principle of a non-volatile septic tank. In MBO systems, work takes place in two modes: sewage treatment and pumping out accumulated sludge. The installation of such a system requires the advice of specialists, since cleaning in it is a technologically complex process.

Energy dependence of structures

Energy dependence is the need to connect to the mains, which not every autonomous sewer needs for a private house and, moreover, for a summer residence.

• VOCs with a complete set of equipment (pumps (airlifts) and compressors - in different quantities depending on the design of the model) are definitely volatile.
• In any case, drives and conventional septic tanks do not need power supply. The removal of gases in this case is carried out using a ventilation pipe, the competent installation of which will ensure the absence of an unpleasant odor in the area, and the drains in the septic tanks pass from chamber to chamber through overflows.

A volatile autonomous sewage system in a private house requires additional operating costs, however, as a rule, it has a higher efficiency (primarily the degree of purification) compared to non-volatile counterparts.

Septic tank for sewerage, plastic, affordable price, buy in Kyiv

Septic tanks for sewerage with a capacity of 1500, 2000, 3000 liters

A sewer septic tank is a facility for treating small amounts of domestic wastewater. It is a plastic underground sump of a horizontal type, consisting of one or more special containers through which the waste liquid flows. In cities and large settlements, sewage is carried out using urban engineering systems. Where there are none, individual wastewater treatment systems come to the rescue. Urban engineering networks for water supply and sewerage are usually not available outside of settlements. There, sewerage is usually carried out using individual (local) wastewater treatment systems. The individual wastewater treatment system is located on its own land plot and is an installation that does not pollute the environment, which creates comfortable living conditions. It does not emit odor, which is evidence of an unsuitable sewage system, and flowing drains do not pose a threat to plants and surface water. Unmanaged wastewater easily finds its way into wells, for example, contaminating drinking water, as well as groundwater and bathing water. The self-contained wastewater treatment system not only does not harm the environment, but also reduces construction costs due to ease of maintenance and long service life. At the same time, the appearance of the land plot does not suffer, since the system is mounted underground and hidden from view. These products can successfully replace any containers that are intended for digging into the ground in summer cottages and land plots.

Septic tanks - the advantages of this technology

- does not require energy, the system works by gravity;

- the whole structure is made of polyethylene;

– high quality wastewater treatment;

- complete absence of unpleasant odor;

- the location of all structural details underground;

— contact of untreated effluents with the living space is completely excluded.

The wall thickness of these products is 8 mm, which allows them to be buried in the ground to a depth of 2 m. At the ends of the tanks GG-1500, GG-2000, GG-3000, two branch pipes with a diameter of 110 mm are installed for connecting sewer pipes. Tanks for 2000 and 3000 liters are completed with a basket for zeolite (filter material). Inside a 1500L tank. an overflow system was installed to prevent the release of sediment and floating contaminants. The tank is completed with an extension pipe with a diameter of 400 mm, a height of 600 mm, through which it is possible to supply a sewage machine hose to the tank for pumping out sediment. Tanks can be connected into tank systems. System can be calculated for the maintenance of both one house and several individual houses.

1 TOPAS 8

One of the most economical energy-dependent septic tanks available to a wide range of consumers. Putting such a tank in the country is not entirely justified - it is much better suited to a small country house. The convenience of manual installation (as in stand-alone models) is no longer ensured here - the entire structure weighs nearly 350 kilograms. Thanks to the installed filters, it does not require cleaning, it well limits unpleasant odors, and also filters up to 1.5 cubic meters of wastewater per day. According to users, the cost of power supply is noticeable, but much less than that of competitors and older models of this series - the septic tank consumes only 1.5 kilowatts per day.
