AWWA D115-06

This standard covers current and recommended practice for the design, construction, and field observations of concrete tanks using tendons for prestressing. This standard covers tanks using bonded circumferential (horizontal) prestressing tendons in the wall or on the wall's exterior surface. This standard does not cover tanks using unbonded circumferential (horizontal) prestressing tendons in the wall or on the walls' exterior surface. This standard also covers the use of bonded or unbonded prestressing tendons, or conventional reinforcing, vertically in the wall and in the floor and roof. This standard applies to containment structures for use with potable water or raw water.
