Describe the bug using the following shapefile, the larger polygons don't return a result , the process hangs before geometry area is calculated

To Reproduce If using a custom shapefile please upload ZIP of the same to project google drive folder GISLayers and add link below. Link: https://drive.google.com/drive/u/0/folders/1Qg44GPY4EYOqmY_pPCbvrAB9w0-iHPw3

Linked to #1 , on resolving the projection issue the water balance is generated in approx ~1min for the larger watersheds. In the future we can attempt to reduce this time further
