A new filling station at the Hanover School Division bus garage will have a positive impact on the bottom line.Transportation Supervisor Ray Fast says a bulk tank with pumping equipment will be installed in the new year.  The Division will realize an annual savings of $15,000 to $17,000.  And by having their own bulk tank they can incorporate a bio-diesel mix in the future.  Fast says there will be a cost to set up the new tank but it will be partially offset by a government grant.  Thirty-eight Steinbach buses and several from the surrounding communities will use the new system on a regular basis.
