Treatment receptacles are required to be watertight. Water tightness testing consists of filling the receptacle with water "to the invert of the outlet", and holding for one hour. Additionally, the joints of the receptacles, including mid-seams, risers, and lids shall be sealed using a bonding compound that meets ASTM C990-96, but no specific water testing is indicated for the risers and lids.
