8.3.2.1
Aboveground Storage Tanks
a)
Piping Arrangement. For large tanks, place inlet
and outlet pipes at opposite ends or sides, to provide
circulation with the outlet pipe near the bottom. Otherwise,
provide baffles in the tank.
(1) Provide overflow and drain pipes discharging
to storm drains, but provide air gap to prevent contamination.
(2)
Place valves on all pipes except overflow
pipes.
(3) Install all valves so that they will stand
out of groundwater or runoff, to prevent possible contamination,
and to be easily accessible to operating personnel.
b)
Depth. The total water depth should be a minimum
of 12 ft to avoid the growth of organisms due to temperature and
the reduction of capacity due to ice.
