ACI 350.1R : 1993

Applicable to cast in place reinforced concrete water containment structures including tanks, reservoirs, basins, conduits, etc. The recommendations are for structures containing water or wastewater. The recommendations are not necessarily applicable to the containment of other fluids, as the viscosities of other fluids are different. However the water tightness test may be used to indicate the tightness, relative to water, for structures containing their fluids. The recommendations are not intended for prestressed concrete structures, for precast concrete structures such as culverts or pipes, for concrete paved structures such as channel and impoundments, for hazardness material containment structures, or for gas containment structures.
