Outdoor sewage

Any sewage facilities periodically need maintenance or repair work. This is equally true for both the local system and the general one. In order to make it possible to implement them, special ladders with relevant technical characteristics are used.

About them and will be discussed in this article.

General provisions

What are sewer systems? These are special facilities for the accumulation and recycling of human waste, which can be divided into two areas:

Types of sewers

Name as per operational coverage Special features
Central public sewage In this case, repair and maintenance work is carried out during the descent into special wells, equipped with the main highway and in the place of discharge of wastewater.
Autonomous sewage Here we are dealing with septic tanks, cesspools or, again, well structures, which may have a sufficiently large depth. Without a suitable ladder, their maintenance will become very difficult.

Stair requirements

From the above table, we see that the conditions in which the work will be carried out are very difficult, which places corresponding requirements for the products:

  1. Water resistance. Depending on the filling level, the sewage environment varies from very humid to liquid. Therefore, in particular, if the ladder is installed permanently, it must be protected from the harmful effects of the liquid.

Tip: eliminate the use of stairs from wood and ordinary iron. Such products will not last long in a humid environment, being exposed to the processes of rotting and corrosion.

  1. Increased strength. Undoubtedly, any staircase design should be reliable according to safety regulations, but in this case, a fall into a well filled with drains can be especially dangerous.
  2. Hooks on top. It is not always convenient to put on the bottom, because from your gaze it hides a muddy slush, it can be slippery or uneven. If you firmly secure the ladder at the top and check the reliability of fastening, you will feel much more confident.
Hooks located on one edge of the product help to fix it better on sheer surfaces

Suitable samples

Instructions for choosing a suitable ladder is very simple, as long as it meets the above requirements and fits the size of your sewer well. Here, for example, the most common models:

Ladders for sewage lines CL 1 and L 1

Metal sewer ladder CL 1

The design of such a plan perfectly copes with its task and has the following distinctive features and features:

  1. It is made of reinforcement with a thickness of 25 mm, which gives high strength.
  1. Stainless steel is used as a material, due to which a wet sewage environment cannot harm the product.
  2. At the top of the structure there are special hooks with which it is securely fixed on the mouth of the hatch.
  3. Affordable price. The manufacturing process is quite simple, which makes the cost of the ladders in question relatively low.
  4. Easy to use do-it-yourself. There is nothing superfluous in their structure that could complicate the operation.
  5. A possibility of application not only in sewer constructions, but also in any other well.

  1. Wide range of sizes:
Possible length, m Weight, kg Approximate cost, p
one 18 850
1.5 35 1150
2 42 1500
2.5 53 1850
3 57 2250
3.5 66 2650
four 74 3000
4.5 80 3400
five 89 3750
5.5 96 4150
6 106 4500
  1. Compliance with all standards TU 5269-006-02495282-2005.

Fiberglass

The use of such material, of course, increases the cost of the product, but also gives it several advantages:

  1. Low weight. It greatly facilitates the transportation and hand-use of the structure, especially in those cases when you require its short-term installation in the well.
  2. Water resistant. No liquid, including various caustic substances, will damage the fiberglass.
  3. It is not a conductor of electric current. This is very useful in case of eliminating various accidents in places where power lines can be located.
  4. High strength and durability. The considered sewer ladder regularly will serve you for many years.

Tip: it is recommended to choose models with steps covered with a special non-slip coating. In a humid environment this will greatly increase your safety.

Conclusion

Sewerage needs maintenance if you want to observe its proper operation. To do this, periodically it is necessary to descend into sewer wells, in which special ladders will help you. Above, we have considered all the features suitable for the implementation of the descent structures.

A quality staircase will make your descent convenient and safe.

The video in this article will introduce you to more information. Carry out maintenance and repair work in the sewage system in compliance with all safety rules.
