Sewerage system in the country with their own hands

To hut is not inferior to a city apartment for the level of comfort, a minimum set of utilities should be to build on the site, one of which is the sewer system.The latter can be equipped with their own hands.

Individual sewerage system can be equipped only with the availability of the central water supply.In the absence of such better dig cesspool and put cottage toilet.

Sump

If the site is connected to the water supply, the house is possible to equip all the facilities - sink, shower and toilet.Wastewater from these devices need

to display outside of the house.To this end, you can put the drive to be cleaned periodically assenizatorskaya machine, or a septic tank - a special cleaning device, providing reuse of wastewater.Moreover, to the main sewage system can be connected to the storm, which will collect and display of the border area precipitation and the water formed when snow melts.

So, sewerage in the country with their own hands must include: sanitary equipment

  • ;
  • domestic sewage, which combines effluents from all devices;
  • external drains to remove water;
  • cleaning device.

Phase 1 Project

Initially, the project is made.Drawing can be done in a simple graph paper, but it is better to use a special utility - it's faster and more convenient.The draft specifies the location of sanitary equipment, pipelines and treatment plants.

Note!Often, for the villa is enough sewage a cleaning unit and a tail pipes.

Advance provides the ability to connect to the system of other buildings on the site - for example, a bath.When calculating the size of the sewage network in the first place the number of residents is taken into account.It is believed that by the average person generates approximately 200 liters of wastewater per day.

In addition, taking into account the climatic features.When it comes to the northern regions of the country, the tail pipes laid below the soil freezing and insulated.Otherwise there is a risk of freezing in winter system.

Step 2: Location of elements sewer

to the location of the network elements, in particular, are on the street, should be taken very seriously.

First of all, take into account the terrain.Usually suburban areas settling the water drain, in which the waste water flows to the disposal site in a natural way.In such cases, the pipes are laid at a certain inclination (about 5 cm per meter) to avoid stagnant wastewater.

Equally important are sanitary norms.According to them, setting unacceptable treatment plants near the wells, wells and other water sources.

also where the unit is tested structures unimpeded entrance assenizatorskaya machine.

Step 3. Cleaning device

ideal option for a suburban area septic tank - advanced analogue sump that requires minimal cost and effort during the operation.Moreover, if equipped with multi-chamber septic tank, the treated wastewater can be reused, for example, for watering the garden or vegetable garden.

There are a large number of septic tanks models produced by both domestic and foreign firms.Each has its own strengths and weaknesses.Most cottages are suitable for septic tanks "Sprout Summer" (cost - about 29 thousand rubles) or "Germ-600" (designed for three to four people, the cost - 15 thousand).But with little volume it is more expedient to build their own septic systems.

Note!Despite the fact a homemade septic or factory, the general rules remain unchanged installation.

How does a septic tank

Septic can be built both with finished parts, as well as "from scratch", but in any case competent installation provides at least minimal knowledge of the principle of workdevice.

Septic - two (at least - three) containers communicating bypass necks.The volume of the first vessel is greater when compared with the others.There fall output from the internal network drains.Characteristically, the liquid stored in each of the vessels a certain time, during which gradually cleared.

The device septic tank

During fluid filtration dissolved gases rise and are ejected, while solids settle to the bottom and form the so-called activated sludge.This sludge anaerobic bacteria live which is cleaved into individual organic chemicals and do not require oxygen.

At the top of the first container set pipe through which treated wastewater overflow into the second.

two or three times, then the liquid enters the last tank cleaning procedure is repeated with the installed sand-stone filtration "cushion".Through this "cushion" the liquid gets into the soil.

Note!To display the filtered sewage into the ground, you can also use a special drainage system.

Construction septic

If you plan to self-manufacture septic tank, we advise you to opt for the major concrete structure.Below is a sequence of actions.

Step 1. first determines the desired cumulative capacity of the device.Ideally, it should be a 3-day volume of waste water of all tenants of the house.Thus, if the house lived three men, the storage tank must be 1.8 cubic meters.

Note!Septic tank is not installed closer than fifteen meters from residential buildings.

Step 2. followed by earthworks.Pulls out a septic pit - either manually or with the help of special equipment.

Step 3. bottom hiding 20-centimeter sand "cushion".

Step 4. formed formwork.Boards or chipboard sheets firmly strengthened, t. To. The weight of the structure is impressive.The formwork is done bypass hole, which is inserted between the walls of a small tube of metal or plastic.

Step 5. reinforcing frame is formed from iron fittings.Intersecting rods bound with steel wire.It is important that none of the valve element does not go beyond the brink of future construction.

Step 6. poured concrete formwork solution, and it should be done in one go.The solution was processed during the pouring vibratory drill - is necessary in order to fill the volume which is limited by the formwork, and remove air bubbles.

Step 7. overlap formed from the boards and metal parts, packed in parallel.On top of stacked elements is laid PE film.Next is a metal mesh reinforcement.When the base is prepared, poured concrete layer.Also, the overlap can be formed from prefabricated concrete slabs laid on a septic tank wall with a gap of up to 2 cm.

Step 8. pit is filled with sand and soil layers.On the surface, leaving only the ventilation pipe (height above the ground up to 1.2 cm) and a cover protecting the mouth of septic cameras.

Note!For this design, you can also use ready-made F / B ring.They are installed directly into the pit.

Stage 4. Laying of sewer pipes

As mentioned earlier, in most cases, the pipeIn suburban areas lay movement for gravity sewage.Therefore, the installation is carried out with a slight slope in the direction of the treatment plant.

Ideally, the pipeline should be flat and have no bends.If this is not possible, at the corners are equipped with inspection pits, through which will eliminate the possibility of error.

Note!At arrangement of the external sewage can be used as plastic and cast iron pipes.The main thing is that they are tightly connected together.

pipes must lie below the freezing of the soil.But if constant slope will be provided, such a recess may not be required.All simply explained: wastewater have a temperature of plus or stagnate therefore not freeze in winter.However, when laying a pipeline shallow insulation needs.

also pipes are protected against possible displacement of soil - they are surrounded by the trench 15 centimeters of sand "cushion".

need to use free-flow principle in settling domestic sewage.Each sanitary device is connected to the pipe diameter concrete - you need to shell cross-section of 50 mm, and the toilet and tail pipes - 100 mm.For the bath and the sink is connected siphon, which prevents the penetration of sewer smell in the room.

In the absence of a central water supply in the country, you can put a bio-toilet (preferably peat).These devices are compact and consist of two containers:

  • top, is intended for the storage of dry peat, and seat mounted on it;
  • bottom, in which excrement is composted.

Dry closets needs regular cleaning, but wastes peat extracted from the bottom of the container, in the future can be used as fertilizer.

Note!In addition to the peat mixture in the design of special bioaktivatory backfilled to accelerate the composting process.Packing activator 30 grams costs about 350 rubles.

Although the plastic housing, a bio-toilet is strong enough and can withstand the weight of up to 250 kg.It is worth noting that there are electric models of toilets - they are not less effective peat, but also stand respectively.Moreover, they need a connection to the uninterruptible power supply.
