Said disposal system to consist of a septic tank and a system of underground drains for the disposal of the tank effluent. Said tank and drains shall be so constructed as to meet the requirements of construction and maintenance hereinafter described.

Said tank shall be of a type, constructed and located in accordance with the recommendations of the State Department of Public Health and the Health Officer.
