Sewerage installation

Installation of sewerage in a private house or apartment is an important stage of renovation work. Usually, it is carried out simultaneously with the installation of a water supply system. It is unlikely that it will go smoothly if the previous stages, including the design and selection of equipment, were performed poorly.

Therefore, we will begin this article with an essential tip: from the very beginning, be responsible in choosing contractors. You should also not save on materials: reinstalling such systems is a troublesome task. Because of this, the price for the installation of sewerage in your house will increase, since you will have to pay extra for the mistakes made.

Alter Air will help create a viable project, install all elements of the internal sewerage system in apartments in multistory buildings and in private cottages.

Installation prices

Below we provide a price list for the installation of sewerage. Pricing for this service is subject to change over time, and these figures are updated for the summer of 2022.

Note that sewerage is an engineering system on which it is not recommended to save money. However, sometimes you can optimize installation costs. The price will ultimately depend on the material or manufacturer of the sewer pipes.

  • Installation of one "water supply points " — 2000 UAH

  • Installation of a pipe made of cross-linked polyethylene with insulation with a diameter of up to 20 mm - 120 UAH/m

  • Installation of a pipe made of cross-linked polyethylene with insulation with a diameter of 25-32 mm - 159 UAH/m

  • Installation of a pipe made of cross-linked polyethylene with insulation with a diameter of 40 mm - 200 UAH/m

  • Installation of a fan riser — 700 UAH/m

Pressure testing and testing of water supply and sewerage systems — 1000 UAH

When to change the internal sewerage

Sewerage is installed during the construction and major renovation of housing. This is one of the important items of expenditure in construction work.

In addition, urgent installation is carried out in case of serious problems - for example, damage to the pipeline. In old houses, it is necessary to change pipes, including risers.

Otherwise, a properly installed and regularly maintained domestic sewerage does not require frequent replacement.

Installation rules for internal sewerage

Sewer installation is always carried out in parallel with the installation of plumbing and heating. The design of these systems is also carried out simultaneously, considering interdependent factors. For installation, the intermediate stage is especially important - when the engineers transfer the drawings to the installation team.

Technical documentation must be prepared – it indicates all horizontal and vertical references, development drawings with references to outlets, water outlets, sewer outlets.

Alter Air has its installers. Thus, trusting us not only with the installation, but also with the project, you entrust the work to one company, which is responsible for the entire process. There will be no communication problems in the team that deals with your project.

The main principle that should be observed when performing installation is the mandatory slope of the pipes. It should be from 1 to 2 centimeters, depending on whether clean water or waste with feces flows through the pipeline. The slope helps to avoid blockages – without it, sewage disposals will not be able to move through the pipes into the drain. For internal sewerage, pipes with a diameter of 20 to 100 mm are used. For example, for pipes in showers, bathtubs or sinks, the pipe diameter is 50 mm, for toilets – 110 mm. Pipes are laid in the walls, not in the floor – this is the only way to achieve the desired angle.

Fan pipes (pipe section that connects the sewer system to the atmosphere) are installed only vertically and go to the roof. The purpose of this type of pipe is to remove odors and air from the sewerage system. For connection, the types “female” or “male” are used, depending on the parts used. When installing an internal sewerage system, it is important to check and eliminate blockages – this is done thanks to pipe clean out.

Features of installation of sewerage in a private house

In most cases, private houses are not connected to the central sewerage system. Waste can be dumped into cesspools, sealed containers, various septic tanks (single-chamber and two-chamber, with a filtration field, with a bio filter), which we described in detail in this article.

Does the installation of the sewerage system in an apartment or a private house differ? Sewerage in a private house can be pricier. You can often hear that for an apartment, you need to use pipes with increased sound insulation. However, in fact, if the main pipeline passes next to the bedroom in the cottage, you will also be disturbed by noise. Therefore, decide on a suitable solution together with specialists, considering the purpose of the rooms, the position of the sewer connections, risers, and so on.

Features of sewerage in an apartment

For the installation of sewerage in an apartment, the price is calculated depending on the number of water supply points.

In apartments of multistory buildings, a sewerage system is usually central – that is, waste is discharged into a centralized city sewer system. Further, these wastes are removed and filtered. Accordingly, the installation is carried out considering this feature.

Work stages on the install

Installation includes the following sequential steps

How to properly install sewer pipes?

It is not recommended to install pipes on your own. Such self-activity leads to improper operation of the system, rapid wear or damage to equipment. If you can immediately entrust the work to professionals – why overpay and waste time?

All work is carried out by Alter Air's specialized installation teams. Specialists must be competent enough to not only read the drawings, but also to anticipate the likely difficulties in the project. If individual parts of the project are not designed with utmost accuracy, the problems must be solved on the spot, with the technical specialist who did this project.

How much does it cost on average to install a sewerage system?

One of the units of cost in sewerage installation is the price per water supply point. Currently, you can count on a cost of 5000 UAH per one water supply point.

You can get answers to questions about the price of sewerage piping and the price of installing sewer pipes after a consultation with our company.

The final plumbing installation quotes is given taking into account your project, type and location of the housing.

What pipes to choose for sewerage installation?

We recommend REHAU and Ostendorf pipes.

However, the choice always depends on the project and your needs. In the issue of sewerage, the price is still a decisive factor, therefore, the selection is also carried out depending on the budget.

We will never insist on a specific brand, but we will talk about the advantages or disadvantages of each option.
