A DYK circular concrete tank is the most efficient shape to contain water.

- DYK tanks are very ductile, enabling them to withstand seismic forces and varying water, backfill and temperature stresses
- DYK tanks utilize material efficiently - steel in tension, concrete in compression
- DYK's "free" wall base and top connections allow the tank wall to move independently, to expand and contract relative to the floor and roof. The independent movement eliminates stress that would otherwise be transferred to the wall
- DYK's vertical prestressing diminishes vertical bending in the wall and subsequent leakage
- DYK's circumferential prestressing counteracts bursting loads from interior liquid

No other concrete structural system can display the efficiency of combining high-strength concrete in pure axial compression with high strength steel in pure axial tension. When a tank is filled with liquid, the liquid exerts pressure in all directions. To contain the internal pressure, DYK prestresses tanks with seven-wire strand. In addition, stored water provides an ideal environment for a continuously curing substance like concrete.
