Species categories of sewer wells
You can avoid errors. The main thing is to know which sewer system can be used. This approach will save you from additional embezzlement and unnecessary inconvenience.
The design of a drainage well depends largely on its species range.
The following categories are distinguished:
- Inspection well in charge of the entire system,
- Delta, used for pipe changes,
- Filtering, helping to get rid of sewage pollution,
- Swivel, which has sharp turns in its schematic device and helps to minimize clogging of the tapsystem,
- Cumulative, important work of drains as a whole.
Sewer well of the named species can perform many functions and carry additional goals and tasks in its purpose. Read more below.
First view:
look-up The name speaks for itself. The inspection sewage septic tank is designed to give a kind of bridgehead for surveying underground communications. Its pipe and manifold are replaced by an open chute. It is often used in cases of changing the direction of the water pipe, the sharp slope of the pipeline and its diameter. The observation well is responsible for cleaning the sewage drainage as a whole.
Second type: Delta
A differential sump is used when pipes of different depths are combined in the same system. Differential wells allow the pipeline to be connected at a level above the portion of the tray section.
Functions:
- Pipeline and manifold connections at great depth,
- Sewage rate reduction( due to a sharp slope of pipeline sections),
- Avoiding intersections of underground structures,
- Unification of the level of drains with groundwater.
The third type: filtration
The purpose of the filtration well is to eliminate wastewater pollution. Construction of this kind is possible in case of accommodation on a sand soil. It is important to take into account: groundwater should be below the base of the well by about a meter, you need a water flow per day of about 50 centimeters( with the calculation for three tenants at home).The area of the well is no less than 1.5 sq. M.m. In the case of a larger number of residents, the water discharge increases to 1 cubic meter.meter( the area of the well grows to 2 square meters).
In the construction market, the filtration sewer is realized by a finished structure. The price is pleasantly surprising. Mounting does not take much time and has a simple circuit. Often the collection and installation does not require a call of a specialist.
Fourth type: rotary
Rotary wells are installed in places of water supply systems with an angle of more than 40-45 degrees and a steep site of pipe joint adhesion. In most cases, it is similar to the lookout.
Fifth type: cumulative
It is often called the most environmentally friendly counterpart of a cesspool. The storage sewerage system has the following advantages:
- Has a wide variation of waste tanks( 2-50 thousand liters),
- Scale of waste tanks does not influence its functionality on the environment,
- No sewage odor,
- Has an underground location, is not visible.
Brief description of
In this section the main information of storage and filtration systems is considered. You should start with the material selection.
The main principle of material selection is economy. Use a durable plastic made of plastic compounds of high rigidity. It is able to tolerate a low air temperature and is distinguished by the special endurance of unfavorable climatic conditions.
Sewage well of a plastic sample is able to withstand high pressure. Hatches made of cast iron have rainwater receivers. There are classes of hatches:
- B( up to 13 tons),
- D( up to 40 tons).
Capacity of the well:
- Height - 2.5 m,
- Diameter - 1 m,
- Pipe depth - 30-40 cm.
The depth of the trench should not be large. A common mistake is the gradual sinking of the earth into a pit that is too deep dug. The earth settles, affecting the slope of the pipeline.
