So that the manner in which the above recited features of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings. It is to be noted, however, that the appended drawings illustrate only typical embodiments of this invention and are therefore not to be considered limiting of its scope, for the invention may admit to other equally effective embodiments.

Figure 1 shows a schematic diagram of the system of present invention and its interaction between two sections namely, tunnel and control room.
Figure 2 shows a line diagram showing essential components of the drainage system of present invention.
Figure 3 shows a line diagram showing the tunnel exit with a self cleaning mechanism.

Detailed description of Invention:
Present invention relates to an automatic drainage system which can sense a rising water level above a threshold limit. As and when the threshold limit is reached the automated system allows a series of drains to open automatically allowing logged in water to flow through the drains to an exit via underground tunnel system.
The invention provides an automated drainage system which means drainage covers, drainage tunnels and exit doors are monitored and controlled by appropriate control elements which is placed in their positions. If the water exceeds Safe height on roads or upper surface of drainage, the system will opens solid drainage plate to drain water on roads, and this system will send the information to control room, the depth of water will be constantly monitored in control room. If any help needed to automated systems then workers will get information from control room after they repair the systems and damages. So, that it is kept under constant vigilance by the supervisors. Also the alarm would be indicated once the operator gets this information and until the problem solved. Servo motor is connected to system to automated controls. When the servo motor is turned on with help of pivot mechanism the catchment basin opens up the door on manhole and then the water drains inside of it. Drained water flows inside the drainage sewer and reaches the exit point. The automated system can be fixed anywhere, where the flood and drainage monitoring is required, irrespective of the kind of fluid involved. The program once fed in the system makes it run with or without software support which makes it very comfortable.

Figure 1 shows the system 100 of present invention into two sections, one being a city water drainage control room 1 and the other section is water drainage tunnels 2. The water drainage tunnels have monitoring systems 3 for monitoring the water level and flow in tunnels and communicating equipment for transfer data to controls room 1. The movement of water into the water drainage tunnels for monitoring the water level and flow in tunnels and communicating equipment for transfer data to controls rooms 2. The automated control system 4 controls the opening and closing of drains for allowing water to pass into the tunnels 2. The city water drainage control room 1 is under human supervision 5 and gets notified7 and rectifies about the flooding and blocked tunnels 2. The control room 1 controls and employees labor if needed to cure the deficiencies in the tunnel 1.
Figure 2 shows the arrangement and placement of tunnels 2 drains 8. These drains 8 are built on low lying areas such as a highway. The drain 8 is covered by drain cover 9. The drain cover has two caps 10 and 11. Cap 10 lies over the cap 11 and has holes to allow water to seep in. While cap 11 is without holes and is in form of a sheet. Opening and closing of the cover 9 is controlled by control system 12. The cover 9 also has a monitoring system 13 attached to it. Sensors 15 are placed to sense rising water level above a threshold limit. The drainage cover 9 placed is balanced on a pivot rod 14. When the sensors 15 sense the rising water level, they send signal to the monitoring system 14 instructs servo motor to allow the drainage cover 9 to spin around the pivot rod 14 and being uplifted to allow drain water to seep into the tunnels 2.
Figure 3 shows tunnel 2 leading to exit. The monitoring system 2 is placed near the end of the tunnel 2. According to an embodiment of the invention, a conventional self cleaning mechanism 16 can be suitably placed at the tunnel 2.
