We present a newly pipeline to analyse polarimetric data: Solvepol. This pipeline is based on existing routines previously developed by our polarimetry group at Instituto de Astronom\'ia, Geof\'isica e Ci\^encias Atmosf\'ericas (IAG) of the University of S\~ao Paulo (USP). Solvepol is completely automatic, speeding up the data reduction time, and is capable of handling large data sets. Solvepol is written in interactive data language (IDL). We present pilot analyses on various optical polarimetric fields that have been previously reduced with our other existing routines, and show that the results from Solvepol are consistent with those reported in the literature. The present pipeline is the basis to develop a reduction pipeline for the optical polarimetric survey SOUTH POL.
