How Do I Construct A Privy To Comply With The Law?
An earth pit privy is only suitable where there is a sufficient depth of soil above either bedrock or the high groundwater table. Article 18.104.22.168 of the OBC stipulates the following regulations for construction of an earth pit privy (earth pit privy figure above):
The bottom of the pit shall be at least 900 mm above the high groundwater table;
The sides of the pit shall be reinforced so as to prevent collapse thereof;
The soil or leaching bed fill around the base of the sides of the super-structure of the earth privy shall be raised or mounded to a height of at least 150 mm above ground level;
The pit shall be surrounded on all sides and on its bottom by not less than
600 mm of soil or leaching bed fill.
