15A NCAC 18A .1959 PRIVY CONSTRUCTION
An "approved privy" shall consist of a pit, floor slab, and seat assembly housed in a building which affords privacy and reasonable protection from the weather.
(1) The pit shall consist of an excavation at least 42 inches square and in no case shall the bottom of an excavation be closer than one foot from the seasonally high water table or rock.
(2) The pit shall be properly curbed to prevent caving. In sandy or loose soil, the curb should extend the full depth of the pit. In tight soils, partial curbing is acceptable if it prevents caving.
(3) The privy floor slab shall be constructed of reinforced concrete. Where it is impractical to secure or construct reinforced concrete floor assemblies, wood construction shall be acceptable provided the floor slab is made of rough sub‑flooring and covered with tight tongue‑and‑groove flooring or other type flooring materials to provide strength and prevent entrance of flies and mosquitoes to the privy pit. Where wood construction is used, floors shall be anchored to at least four‑inch by four‑inch sills.
(4) Wood used for riser, seat assemblies, and the floor slab shall be tongue‑and‑groove or plywood (exterior or marine) material.
(5) Privies shall not be used for the disposal of water‑carried sewage.
