A conductive tank sump (100) and a dispenser sump (200) ensuring dissipation of electrostatic charges is disclosed. The sumps (100, 200) which are fully conductive through underground comprising (a) a sump wall made from fiberglass composition impregnated with conductive resin; (b) a ground block (16, 26) secured at the inner surface of the sumps (100, 200); (c) a plurality of pipes mounted through holes provided on the wall of the sumps (100, 200); (d) a plurality of grounding cables (116, 226) connecting the pipes and/or isolated conductors which needs to be earthed to the ground block (16, 26) on the wall of the tank sump/dispenser sump (100, 200). The present invention also relates to method of grounding of the tank sump/dispenser sump (100, 200).
