Where this article requires a particular type of sewage disposal facility the use of any other type, or disposal by any other means, is hereby expressly prohibited, unless approved by the Health Officer. The Health Officer is authorized to approve exceptions to the provisions of this article only when the lot size, soil composition, lay of the land, or other unusual circumstances make the installation and use of the prescribed facilities unfeasible. Neither shall the Health Officer approve any installations under Section 921.05 unless conditions favor such installations as adequate for the protection of the public health.
