The building shall be equipped with a tight fitting, self-closing door and shall be weather-proof;

The contents of the pit shall not be permitted to overflow onto the surface of the ground or be exposed to flies or rodents;

(E)

A minimum of one-half pound of chlorinated lime shall be deposited in each pit once every 24 hours;

(F)

At the conclusion of the outdoor mass gathering, the contents of the pit shall be covered by backfilling with at least a two foot depth of earth.

In areas where high water tables are encountered, concrete vault privies, pail privies, chemical toilets or incinerator toilets shall be used in place of earth pit privies for disposal of human excreta. All vaults and receptacles of such privies shall be water-tight and constructed of reinforced concrete, plastic, fiberglass or metal:
