Earthing system depends upon the soil resistivity, to calculate the no. of earth pit. one should know the soil resistivity. only after that you may calculate no. of pits, treated or un treated earth pit and cross section area of downrod or pipe dia. Earth pit resistance value also depends upon material which is being used for the earth pit.
