What is a sewage pit and what is its use?

Pit is one of the main and integral components of the sewerage network and has many applications in municipal sewerage pipelines and plumbing in Toronto. So that in all alleys and streets and wherever there are large sewer pipes, a pit can be seen next to it. The use of pits has been common in the past and its use has been easy access to different parts of the sewer network. In fact, each pit is an access station to the sewer pipe and equipment of the municipal sewerage network through which technicians enter the sewerage network and observe and check the status of the system.

What is a pit?

A pit is a pit access to a sewer network through which sewer pipes can be accessed. Pits are used to connect multiple sewer networks to each other, allowing sewer technicians to inspect, maintain and maintain it. There are many pits in the municipal sewage collection network.

Pit efficiency, as mentioned, is to set up a station to inspect and inspect the sewer system. Pits are used to inspect, repair and view sewer pipes and also create ventilation in the system. Today, with the expansion of the municipal sewage collection network and the increase in the number of pipes, the number of pits has also increased, and you can see a number of these pits in every alley and street at short distances.

If you pay attention, there are round and iron sewer valves in the streets, which are called sewer valves, and in fact they are pit valves. Below these valves is a sewer pit where the relevant technicians open the door and check the condition of the pipes.

Types of sewage pit

There are different types of pits that are of different sexes. Also, the size of the pits is different from each other and according to the type of network and the size of the sewer pipes and the need for more space, they use different sizes. However, regarding the type and material of the pits, it should be said that the pits are made of three types of bricks, concrete and polyethylene. Each of these pits is used in special cases, and each of them is described in detail. Be.

Brick pit

The first and simplest type of pit is a brick, which is a traditional type of pit and has been used in the past. In this way, a room was created in the desired place using bricks and masonry and a door was placed on it. This type of pit is the simplest type that has been used in the past and has been used due to lack of facilities.

A brick pit has a low cost. But it also has many disadvantages. Disadvantages of brick pits include vulnerability to earthquakes and possible pressures and shocks, limited size and volume of the manhole, the possibility of subsidence and destruction over time, the possibility of sewage leakage into it and so on. Due to its many disadvantages and the existence of other better types, brick pit is not used.

Concrete pit

With the passage of time and the inefficiency of the brick pits, the concrete pit was built and replaced the brick type and was able to occupy a high share of sewage pits. These types of pits are much better and more durable than brick manholes, but they still have disadvantages. Cost is higher than brick type, construction time, high weight for transportation, possibility of water leakage in it are among its disadvantages. Of course, care must be taken not to confuse a concrete pit with a concrete septic tank because the two are different.

Polyethylene pit

Again, due to the inefficiency of concrete pit, a new type of polyethylene has been created, which is called polyethylene pit. This type of pit is recently produced and is the best and most suitable type of pit and has a lot of efficiency. The many features of these pits have made all pits made of polyethylene in developed countries. But in the country, most pits are made of concrete, and polyethylene pits have not yet found their place in the sewage and plumbing market.

Polyethylene pit has many properties, including low weight, high flexibility, high consistency and strength, and so on. Although these pits have to be made in the factory, their low weight makes them easy to transport and easy to install. Regarding the low weight of these pits, it should be said that polyethylene is much lighter than concrete and has high strength against its own weight. This has made these types of pits very popular. Also, regarding the installation of these pits, it should be said that due to its low weight, it can be easily installed in any place and does not have the difficulties of a concrete pit.
