How to make a sanitary drain

The toilet drainage pipe must also have a slope. This general unevenness avoids the retention of wastewater and allows the evacuation to be done correctly. Also all the perimetral sills of the house must have at least 2% of unevenness, so that the rain water is not retained and poured towards the channels or grids and corresponding manholes.

In the roof the slopes are more pronounced, depending on the type of tile or covering material and the climatic zone, with more or less rainfall and with more or less snow precipitation. The Technical Building Code (CTE) defines minimum slopes. In a curved tile roof, it is set at a minimum of 32%.

Sanitary drainage of a house

ARTICLE 130. ACTIVITIES FOR THE FILLING AND START-UP OF THE PTAP. In order to start operations, the drinking water treatment plants must meet and be received to the satisfaction of the person providing the service, the following requirements:

2. preliminary inspection and acceptance of elements and equipment: procedures shall be carried out and documented to verify the installation and calibration of electromechanical and dosing equipment, the preparation of chemical solutions for use in the processes, and the verification of the operation of elements, for example opening and closing, such as valves and gates.

3. General cleaning and disinfection of the treatment units: all interior surfaces that will be in contact with water should be disinfected; to carry out this procedure, the methods recognized nationally or internationally by standards such as NTC, AWWA, UNE can be used as a basic reference.

4. Start-up and commissioning failures: once the start-up and commissioning of the facilities has begun, none of its components, whether equipment, instruments or units, may present more than five monitored failures in an interval of 48 hours each and, in this case, the start-up period must begin again.

Drainage pipe diameter

Immediately it is worth making a reservation that the maximum possible slope of the sewer pipe is not the best solution. When the slope is too high, the liquid flow will be fast, but because of this, the smells of feces will be felt inside the apartment. If the bias is too high, there are cases of breakthrough siphons.

Inside the apartment, there is practically no way to measure the flow of liquid in the sewage system with our own capabilities. Professionals are advised to take into account the permissible figures indicated in the normative tables. According to the recommendations of SNiP, the flow rate should be 0.7-1 m / s.For this speed, the standard angle of inclination should be for products with a diameter of:

You can determine the standard bias yourself. The main difficulty lies in the unusual units of measurement of the slope, which are indicated in the regulatory documentation. In the main guidelines, slopes are measured in decimal fractions of the form 0.03 or 0.008.
