Introduction

Every year, a person improves water supply and sanitation technologies. Water supply systems to consumers serve for uninterrupted, high-quality supply of water at any time and in the necessary quantities. Along with water supply also water disposal systems (sewerage) for reception, removal, utilization, processing of the fulfilled water and waste products of the person develop.

Modern systems provide water supply with significant losses, which reach 50 percent. This adversely affects the environment, while depleting natural water sources and contaminating them with waste water in excess quantities. High water consumption and losses lead to overloading of treatment facilities, as well as to a deterioration in water quality, which negatively affects the health of the population.

Professional maintenance and operation, as well as reconstruction of the water supply and drainage systems of the house, guarantees the reliability of the water supply and waste water removal systems, the durability of the building. The task of the designers is the expedient selection of engineering equipment and devices, the design of water supply and sanitation systems taking into account the requirements of regulatory documents for comfortable living of people.

In view of the rapid development of the scientific and technological process, the solution of engineering problems in water supply and sanitation becomes of great importance for specialists in all parts of the country. The management of water resources, the solution to the issue of their reproduction, is also one of the most significant problems .

That is why the design of water supply and sewerage systems is in demand and relevant always and everywhere.

Water disposal system

4.1. Water Disposal System Design

Drainage ( sewage) system - a system of pipelines and devices that provides waste water removal from sanitary and technical devices and technological equipment, and, if necessary, local treatment facilities, as well as rain and meltwater to the sewage network of the corresponding purpose of a settlement or industrial enterprise.

The internal sewage system is designed to drain sewage from sanitary devices through the outlets, first to the courtyard sewage system, and then to the street.

The movement mode of the sewer network is gravity, self-cleaning, turbulent, pressure-free. The sewerage works with incomplete filling and is performed with the help of shaped and connecting parts. All connections are only smooth, the angle of 90 degrees is not recommended and is obtained by connecting either two taps at angles 45 + 45 or 30 + 60, or an oblique tee at 45 or 60 degrees and tapping at 45 or 60 degrees.

On the plan of the basement we show and mark the risers, schedule issues, number the wells of the palace network. The movement of waste water in the building shall correspond to the movement of waste water outside the building.

For all sanitary devices, 7 sewage risers are designed, which enter the yard sewage network through two outlets. Sanitary and technical devices are connected to risers by branch lines with a diameter of at least 4050 mm. When a wash, washbasin or bath is attached to the riser, the diameter of the network pipes is 50 mm, when a toilet is attached - 100 mm.

Drain pipes are laid on walls above the floor by 0.2 m. All horizontal and drainage pipelines are calculated based on the condition that they provide a gravity flow mode of effluents at a rate not less than the value of the self-cleaning speed of 0.7 m/s. The diameter of the drain riser shall be at least the largest diameter of the floor branches connected to this riser.

To control the drainage and cleaning of pipes at a height of 1 m from the floor on the first and last floors, we install revisions, as well as install cleaning in the basement on horizontal sections of the sewer network.

The domestic drainage system networks that discharge waste water to the external drainage network must be ventilated through risers. As a result, we combine the risers into ventilation shafts and lead to the ventilation channel on the roof of the house. The exhaust part of the riser rises above the roof plane by 1 m. The diameter of the exhaust part is equal to the diameter of the sewage riser.

The yard sewer network is designed from LPA type pipes (GOST 185992001) with a diameter of 160 mm. The minimum depth of sewage pipes shall be taken to be 0.3 m higher than the freezing depth, but not less than 0.7 m up to the top of the pipe in order to avoid forcing of soil by large-capacity (truck) vehicles and destruction of sewage pipes.

We accept depth of laying 0.7 m at freezing depth 0.7 m.

The courtyard network is laid parallel to the external walls of the building along the shortest path to the city collector. The distance from the exterior wall of the building to the pipeline axis is 3 m.

Inspection wells of non-drainage networks are installed at connection points, at points of change of direction, slopes and diameters of pipes.

At the points where the outlets are connected to the yard network, the inspection well KK11 and KK12, the rotary well KK, are designed. The outlets are connected to the yard network at an angle of 90 degrees in the direction of fluid movement.

In order to avoid exceeding the maximum allowable speed of waste water (4 m/s), we install a control differential well - KK, which is necessary due to the large difference in the depth of the yard sewage network and the city drainage collector. At the point of connection of the yard network to the city drainage network, a city well (GK1) is arranged.
