After the building foundation is laid, the reinforcements are placed. While the foundation reinforcements are being completed, the manhole locations around the building are also determined. Between the reinforcements, the pipes from the foundation slab are extended towards the ground. Manhole structure is built to connect Pimaş pipes. This entire system is designed according to the previously prepared storm water project.

With the prefabricated chimney elements sold in the market, manholes are manufactured around the entire foundation and according to the project. In the past, it was created according to the formwork system. Due to the lack of a homogeneous structure in the manholes created according to the mold system, cracking and breaking occurred. In those manufactured with prefabricated concrete, these problems are relatively few.

All chimneys are connected to each other with 200 millimeter corrugated or concrete pipes. A certain slope is given when digging the bed for the pipe. Soft sand and gravel are laid under the pipes so that they are not affected by collapse or soil load. Thus, the pipe is not affected by soil load and precipitation.

The entire system we have tell above is connected to the chimney, which belongs to the city network, in the nearest time. Elements such as roads and electricity poles are taken into account when making the connection.

Thus, the storm water system of the entire building is prepared.
