Therefore the capacity must be increased to the desired extent by extending the length; but where, of necessity, the length is limited, the requisite capacity can be readily and economically obtained by building two or more tanks side by side, which may be arched or vaulted over from the side to the dividing walls. When the underlying rock consists of impertransible clay, free of springs, the expense will not be great in flagging the bottoms of the tanks, and building side walls and arches; but when, on the contrary, the excavations necessary for the construction of tanks are made in ground of a wet and pervious character, or subject to springs, then the following precautions should be adopted in order to prevent the contents of the tanks from leaking, or the external water from forcing an entrance. In the case of springs the remedy is obvious, simply to intercept and discharge them into the nearest drain or outlet. In the other case, the tanks ought to be puddled with good cohesive clay, behind and under the stone and brick work. This should be done in the following manner:--A layer of clay, well tempered with sufficient moisture to render it slightly cohesive, should be spread over the bottom of the excavation, and well beaten and rammed down about a foot in depth, and a foot every way beyond the intended foundation of the walls.
