Abstract: A tank has a circumferential wall defined by a plurality of separate elements in the form of vertical staves. Adjacent elements are shaped so that they are squeezed together to prevent leakage past adjacent elements. Hoops surround the wall elements. One hoop is a plurality of segments. Truss rods connect separate elements of the hoop to a support inside the tank. The truss rods of the hoop connect the hoop segments to the inside support in the tank and are tightened thereto for drawing the hoop wall elements inward to the truss rod supports, squeezing the adjacent wall elements together for preventing leakage between adjacent elements. A divider across the tank has the supports thereon for receiving the ends of the truss rods in the tank. Other staves define a divider of staves. Vertical beams support them.

Abstract: A wooden water tank for a building has a tank wall, a tank bottom and a wooden dividing wall across the tank defining at least two water compartments. There are attachments between the foregoing parts, and leak preventing connections between parts. The dividing wall is a sequential series of staves or boards extending horizontally and pressed secured together for leak prevention.

Abstract: A wooden water tank for a building has a wooden tank wall, a tank bottom and a wooden dividing wall across the tank defining at least two water compartments. There are attachments between the foregoing parts, and leak preventing connections between parts. Each wall is a sequential series of staves or boards secured together for leak prevention. The staves of the circumferential tank wall extend vertically. The staves of the dividing wall extend horizontally. The staves are all pressed together so that neighboring staves are sealed to each other preventing leakage through the walls. There are hoops and hoop segments around the circumferential wall, and connections to the hoops press the staves of the circumferential wall toward each other for sealing.
