What is the difference between a sewer network and a drain?

Sewer networks and gutters are two different types of drainage systems, and their main differences are in the way they are drained and the application scenarios.

A sewer network is an underground drainage system that is mainly used for the discharge of sewage inside cities and buildings. It consists of a series of pipes, manhole covers, pumping stations, etc., which collect sewage from houses, roads, public places, etc., and discharge it into rivers, lakes or oceans after treatment. The advantage of the sewage pipe network is that it can effectively control the discharge of sewage, reduce environmental pollution, and also save water resources.

A drainage ditch is a surface drainage system that is mainly used for drainage in farmland, roads, parks, and other places. It consists of one or more ditches that discharge rainwater, groundwater, and other sewage into rivers, lakes, or oceans. Drainage ditches have the advantage of being able to drain rainwater and groundwater quickly, prevent water from flooding the ground, and protect infrastructure such as farmland and roads.

In general, both sewage networks and drainage ditches exist to solve drainage problems, but they have different application scenarios and drainage methods. Inside cities and buildings, sewerage networks should be used to collect and treat sewage; In places such as farmland, roads, and parks, drains should be used to drain rainwater and groundwater.

The difference between sewage pipes and drainage ditches is mainly that sewage pipes are mainly used to discharge sewage, while drainage ditches are not actually used to discharge sewage, but to discharge rainwater and the like, so for environmental protection, they cannot be used together in many cases, and rain and sewage should be separated.

Of course, there is a difference between the sewage network and the sewage in the sewage network is directly flowing into the sewage treatment plant for purification. The drain is a natural water, which can be discharged directly without purification!

The sewage pipe is to discharge domestic sewage, and the drainage pipe is to discharge rainwater, which is really helping you look forward to it

Stormwater pipes are pipes that collect natural rainwater from the ground and transport it to natural water bodies. Sewage pipes Sewage pipes are pipes that collect used sewage and wastewater, which are usually transported to sewage treatment plants to meet discharge standards before being discharged into water bodies or for recycling. The sewage pipe is the pipe network that discharges and transports sewage, and the drainage pipe is the pipe that discharges various water sources, so the sewage pipe is one of the drainage pipes.

Look at the signs on the manhole cover, there is a difference between rain and pollution. In addition, in order to facilitate drainage, the sewage pipes are generally located close to the building, and the rainwater pipes are placed in the middle of the road. The materials used to make rain and sewage pipes are made of polyvinyl chloride resin as the main raw material.

The pipe diameter of rainwater should also be slightly larger, generally the pipe diameter of the starting point is 300, and the sewage pipe diameter is 200.

In general, the function of the drainage pipe is to discharge relatively clean and odorless water, and the sewage pipe is to discharge water with a heavy odor of urine and urine. The drainage pipe can be discharged directly, and the sewage pipe should be degraded and discharged by the septic tank.

If the drain pipe is connected to the sewage pipe, when the sewage pipe is flushed, the odor in the pipe may be squeezed out of the drain pipe trap through the air flow, causing indoor air pollution. In the same way, if the sewage pipe is connected to the drainage pipe, it will cause pollution of the drainage pipe, causing pollution around the mouth of the drainage pipe. According to the conventional connection method, the sewage pipe is only connected to the squatting toilet, and will not be connected to other pipes.

The drain pipe nozzle has a waterproof treatment, so there will be no problems under normal circumstances.

Sewage pipes are pipes that collect used sewage and wastewater, which are usually transported to sewage treatment plants to meet discharge standards before being discharged into water bodies or for recycling. The sewage pipe is the pipe network that discharges and transports sewage, and the drainage pipe is the pipe that discharges various water sources, so the sewage pipe is one of the drainage pipes.

1. The rainwater pipeline is a pipeline that collects natural rainwater from the ground and transports it to the natural water body.

2. The sewage pipeline is a sewage pipeline that collects people's domestic sewage. It is usually transported to a wastewater treatment plant to meet discharge standards before being discharged into a water body or recycled.

Sewage pipes are sewage pipes that collect people's domestic sewage. It is usually transported to a wastewater treatment plant to meet discharge standards before it is discharged into a water body or reused.

A storm sewer is a pipe that collects and transports natural rainwater from the ground to a natural water body. Sewage pipes are pipes that collect people's domestic sewage. This water cannot be discharged directly into a water body or recycled. It must first be transported to the sewage treatment plant.

Stormwater pipes are pipes that collect natural rainwater from the ground and transport it to natural water bodies. Sewage pipes are sewage pipes that collect people's domestic sewage. It is usually transported to a wastewater treatment plant to meet discharge standards before it is discharged into a water body or reused. A sewer pipe is a network of sewage discharge and transportation.

Stormwater pipes and sewer pipes are plumbing systems that are used to discharge different types of water, and they differ in the following ways:

Uses: Stormwater pipes are mainly used to discharge rainwater from the surface of buildings, roads, etc. to sewers or other collection systems. Sewage pipes are mainly used to discharge domestic sewage and wastewater, including sewage generated by kitchens, bathrooms, toilets, etc.

Shape: The shape of storm sewers is generally square or round to accommodate different drainage needs. Sewage pipes are usually only round because round pipes are more fluid when discharging sewage.

Material: The material of the rainwater pipe can be pure copper, PVC (polyvinyl chloride), color aluminum, etc., these materials have corrosion resistance and weather resistance. Sewage pipes are generally made of PPR (polypropylene) because PPR has good chemical corrosion resistance.

Installation location: Storm sewers are usually installed on exterior walls to allow for rapid drainage of rainwater. Sewage pipes are generally installed on indoor walls or underground to collect and discharge domestic sewage.

Color: The color of the storm sewer is relatively diverse, and different colors can be selected according to the appearance and design needs of the building. Whereas, sewer pipes are usually only white, which is for easy inspection and maintenance.

To sum up, there are obvious differences between stormwater pipes and sewage pipes in terms of use, shape, material, installation location and color to adapt to the discharge needs of different types of water.

Stormwater pipes and sewer pipes are piping systems used to discharge different types of wastewater, and the main difference between them is the nature of the wastewater discharged and how it is treated.

1.Stormwater pipes: Stormwater pipes are mainly used to discharge rainwater and surface runoff water.

It collects and discharges rainwater formed by precipitation as well as stormwater runoff on the ground, such as rainwater in rainwater harvesting systems and stormwater drains. Stormwater pipes collect rainwater by discharging it from surfaces such as buildings and roads into rainwater harvesting systems or natural water bodies. Because these water sources do not contain contaminants (e.g. chemicals, bacteria, etc.), storm sewers do not require special treatment and are usually discharged directly into the appropriate drainage system.

2.Sewage pipes: Sewage pipes are used to collect and discharge domestic sewage, including toilets, washing utensils, kitchen wastewater, washing machine wastewater, etc.

Wastewater contains contaminants such as organic matter, bacteria, chemicals, etc., so it needs to be treated before it can be safely discharged into the environment. The sewage pipeline collects wastewater from residential, commercial or industrial areas to the sewage treatment plant, and goes through a series of purification and treatment processes to remove pollutants and impurities, so that the water quality meets the discharge standard before discharge.

To sum up, stormwater pipes are used to discharge rainwater and surface runoff water and do not require special treatment; Sewage pipes are used to collect and discharge domestic sewage, which needs to be treated before it can be discharged. The difference between them is mainly in the nature of the wastewater and how it is treated.

Drainage ditches or interception ditches are used to drain rainwater, and now sewage is generally not allowed to be discharged openly.

1. The essence is different.

The sewage pipe is the pipe network that discharges and transports sewage, and the drainage pipe is the pipe that discharges various water sources, so the sewage pipe is one of the drainage pipes.

The drainage pipe is a new type of corrugated plastic pipe formed by adding other additives to high-density polyethylene (HDPE), and the permeable corrugated pipe is made by punching holes in the groove and wrapping needle-punched geotextile around the outside of the pipe.

2. The role is different.

The function of sewage pipes: vertical and horizontal drainage of the back of various retaining walls and side ditches of highways; drainage of tunnels and underpasses; Water supply and drainage of municipal engineering, water purification plants, sewage plants, garbage dumps, etc.

The role of the drainage pipe: it is used for water supply, and some are used for farmland irrigation, the biggest difference with the drainage pipe is that it needs to be able to withstand pressure, if it is a water supply project, it is also necessary to have health indicators, non-toxic and non-polluting and other detection indicators.

Classification of drains

According to the type of bellows, it can be divided into single-wall permeable bellows and double-wall permeable bellows.

Because the pipe hole of the product is in the trough and is elongated, it effectively overcomes the drawbacks of the flat round hole product that is easy to be blocked and affects the drainage effect, according to different drainage requirements, the size of the pipe hole can be 10mm 1mm-30mm 3mm, and can be evenly distributed in the range of 360 degrees, 270 degrees, 180 degrees, 90 degrees, etc., and is widely used in the drainage fields such as highways, railway subgrades, subway projects, landfills, tunnels, green belts, sports fields and slope protection caused by high water content. and underground irrigation and drainage systems for agriculture and horticulture.

Together with soft permeable pipes and plastic blind ditches, it has become the three main products in China's civil engineering construction (water seepage and drainage). Depending on the size of the drainage pressure, the municipal drainage pipe network can choose double-arm bellows and straight-wall pipes. The straight-walled pipe has a strong pressure bearing capacity and can be used for special pipes in large-scale drainage and sewage pipe networks.

1. The key calendar is different: DN means the nominal diameter of the pipe, which is the average of the outer diameter and the inner diameter, and is called the average inner diameter. DE means pipe outer diameter. Indicates the outer diameter of the pipe.

2. Describe different types of pipes: the nominal diameter of DN is the nominal of cast iron pipes, seamed steel pipes, concrete pipes and other pipes, but seamless steel pipes do not use this representation; DE for plastic pipes; Describe the nominal diameter of the seamless steel pipe.

3. The writing method is different: the nominal diameter is represented by a numerical sign followed by the letter "DN", as a sign symbol, and the size of the unit is millimeters indicated after the symbol; Generally, if DE is marked, it needs to be marked in the form of outer diameter x wall thickness; The nominal diameter of the seamless steel pipe is, e.g. 100:108 x 4.
