We demonstrate that an $SU(2)_L\times U(1)_Y$ model with the same particle content as Standard Model(SM) and discrete reflection symmetry between second and third generation of leptons give rise to charged lepton and neutrino mass matrices which can accommodate the present solar, atmospheric, WMAP neutrino experimental results.The model predicts the value of $|U_{13}|$ which could be tested in neutrino factories and the value of the effectiv Majorana neutrino mass $$ comes out at the lower end of the present experimental limit. Neutrino masses are generated through dim = 5 operators and the scale of which is constrained by the value of $$. If, in future neutrino less double beta decay experiments, namely, MOON, EXO, GENIUS etc. shifts the lower bound on $}$ by one order the present model will fail to accommodate the solar neutrino mixing angle due to LMA solution.
