No service pipe shall be allowed to run across lots, that is, from one lot to another, but it must be taken from the main in front of the premises or from some point adjacent thereto, unless specific permission is obtained from the director of public works. The director of public works shall have the power to extend service pipe to a building abutting a main. All additional expenses for such extensions shall be paid by the owner of the property.
