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
