The recent incidents of torrential rainstorms across the country of 
Azerbaijan, especially in big cities, and even around the world have 
highlighted one of the serious problems of intensified flooding events. In case 
of high amounts of precipitation and excessive water consumption, the street 
sewers are getting clogged with waste material. The fact that most of the

systems designed for the flood protection lacks the capability to keep up with 
the innovative and latest technologies is concerning and for that reason, the 
primary objective of our idea while designing the suggested system was to 
alleviate the impact of the flooding by means of novel tools and systems.
The proposed system can be directly applied to common sewers where 
clean and waste fluids are transported together. If sanitary and stormwater 
sewers are used to carry different types of fluids separately, then keeping the 
same process design, different sensors will be required due to diverse 
mixture properties of fluids. The whole operation of this system occurs in two 
major parts:
1. Execution unit where the sensors detect the presence of rising sewer 
fluids 
2. Main unit where the reached signals are processed, and corresponding 
notifications are selected 
In execution unit, to determine 
the rising level of the sewer fluid, 
we will need: 

a long, medium-width rod 
(planned to be at least 2 
meters long, but can be 
adjusted according to the 
applied system)

hydrostatic 
pressure 
sensors (depending on the 
sewer type, other suitable 
sensor types can also be applied) 

a heavily insulated, flexible, cold-resistant cable (for underground 
transfer of sensor data to sewer alarm meter) 
The rod with the wire planted within it will be attached to the sewage tank 
from above (see Figure 1). This rod has at least two sensors, one at the 
bottom and another one at the same level as pumps coming from residual 
areas. The fundamental objective is to detect the presence of rising fluid as 
soon as it reaches the predetermined sensor levels, and to display the 
matching notification after processing. Every 15-20 seconds, the live data will 
be transmitted to the main unit through underground cables.
After the main unit receives the live information from sensors, initially 
yellow, then red light will glow, meaning warning and emergency, 
respectively (see Figure 2). Once the red light is on, the emergency signal 
will be immediately transferred via wireless connection to the responsible 
Water Company in order for the staff members to take precautionary 
measures. Regarding the yellow light, originally, its use was to let the 
residents of the street be aware of the upcoming disaster related to imminent
