REVIEW QUESTION 1
Figure 3-1 is a construction print describing a water supply system. The drawing shows that the water is
pumped from the supply source (stream) into a surge tank and then to the sand filtration system. After filtration, the
water is pumped from a 3-foot x 3-foot box to a purification unit. Assuming that the horizontal length of the slanted
side of the sand filter is 8 feet, what distance, in feet, is the edge of the sand filter above the floor of the
sedimentation basin? (para 3-2) (fig 3-1)
REVIEW QUESTION 2
Figure 3-3 shows the details of the roof plan for a water tank and tower. By looking at the schedule you
can see that specifications are given for more than one type of tank and tower. If a tank with a 21,000-gallon
capacity was to be constructed, what type of steel beam would be used and what would be the center-to-center
placement distance? (para -4, a) (fig 3-3)
