DN Tanks



DN Tanks (formerly Natgun) designs and constructs prestressed concrete liquid storage tanks. The tanks are American Water Works Association (AWWA) D110 prestressed wire-wound concrete tanks that incorporate precast concrete panels. SGH developed a seismic design procedure for the domes and peer reviewed the tank designs. We used the procedure to design a number of tanks constructed in high seismic regions.
