Claims:WE CLAIM:
1. A method for determining occurrence of sewer flooding in a geographical area, comprising:
retrieving, by an occurrence determination system (101), one or more attributes (208) associated with a geographical area, wherein the one or more attributes (208) comprises historic data associated with a sewer network in the geographical area, one or more characteristics of the sewer network, weather parameters relating to the geographical area, blockage data and complaint data associated with the sewage network;
generating, by the occurrence determination system (101), one or more sewer flooding factors (209) influencing occurrence of sewer flooding in the geographical area, based on the one or more attributes (208);
identifying, by the occurrence determination system (101), one or more predictor variables (210) from the one or more sewer flooding factors (209) based on score (211) generated for each of the one or more sewer flooding factors (209) using a scoring technique; and
providing, by the occurrence determination system (101), the one or more predictor variables (210) to a prediction model (104) trained based on the historic data associated with the sewer network and the one or more characteristics of the sewer network, for determining occurrence of the sewer flooding (213) in the geographical area.

2. The method as claimed in claim 1 further comprising, generating a geo-spatial map (214) for the geographical area based on the determined occurrence of the sewer flooding (213).

3. The method as claimed in claim 1, wherein the historic data comprises previous flooding incidents associated with the sewer network.

4. The method as claimed in claim 1, wherein the one or more characteristics of the sewer network comprises flood interceptor removed status, flood resrelbus closure status, manhole located status, location trap, turning chamber, removal type and interceptor trap.

5. The method as claimed in claim 1, wherein the one or more sewer flooding factors (209) are generated by using data mining technique on the one or more attributes (208).

6. The method as claimed in claim 1, wherein determining the occurrence is based on weights (212) generated for each of the one or more predictor variables (210) in correspondence with each of one or more predefined outputs of the prediction model (104).

7. An occurrence determination system (101) for determining occurrence of sewer flooding in a geographical area, comprises:
a processor (105); and
a memory (108) communicatively coupled to the processor (105), wherein the memory (108) stores processor-executable instructions, which, on execution, cause the processor (105) to:
retrieve one or more attributes (208) associated with a geographical area, wherein the one or more attributes (208) comprises historic data associated with a sewer network in the geographical area, one or more characteristics of the sewer network, weather parameters relating to the geographical area, blockage data and complaint data associated with the sewage network;
generate one or more sewer flooding factors (209) influencing occurrence of sewer flooding in the geographical area, based on the one or more attributes (208);
identify one or more predictor variables (210) from the one or more sewer flooding factors (209) based on score (211) generated for each of the one or more sewer flooding factors (209) using a scoring technique; and
provide the one or more predictor variables (210) to a prediction model (104) trained based on the historic data associated with the sewer network and the one or more characteristics of the sewer network, for determining occurrence of the sewer flooding (213) in the geographical area.

8. The occurrence determination system as claimed in claim 7 further comprises the processor (105) configured to generate a geo-spatial map (214) for the geographical area based on the determined occurrence of the sewer flooding (213).

9. The occurrence determination system as claimed in claim 7, wherein the historic data comprises previous flooding incidents associated with the sewer network.

10. The occurrence determination system as claimed in claim 7, wherein the one or more characteristics of the sewer network comprises flood interceptor removed status, flood resrelbus closure status, manhole located status, location trap, turning chamber, removal type and interceptor trap.

11. The occurrence determination system as claimed in claim 7, wherein the one or more sewer flooding factors are generated by using data mining technique on the one or more attributes (208).

12. The occurrence determination system as claimed in claim 7, wherein the occurrence is determined based on weights (212) generated for each of the one or more predictor variables (210) in correspondence with each of one or more predefined outputs of the prediction model (104).
