The majority of gas stations or filling stations
are constructed very similar: the fuel is stored underground; there
is a machine of which to pump the fuel at the front of a building
and payment is rendered within the building or at the pump.
Gasoline tanks are located underneath the ground. The installation
of underground tanks is the most general however when certain
environmental laws are not permissive as to the construction
formerly described a surface tank may be the solution.
The gasoline is generally loaded into the gasoline station's
storage tanks by way of a truck and through a valve. The gas which
is loaded from the tanker flows by way of pipes located beneath the
earth's surface and to the pumps where the gasoline is to be
A person seeking to add gasoline to his or her car must be allowed
access to the pump or the pump will need to be turned on by a
gasoline attendant. The pump is normally as previously alluded to
at the front of the station.
The more retro-style filling stations essentially use segregated
piping for each type of fuel and respective pump. The more
modernized filling stations generally use an individual piping
construction for all of the gasoline dispensers. The main pipe is
associated with small pipes which are relative to the various kinds
of fuel oil.
There are recovery systems in place with regard to vapor within the
gas tanks, nozzles and gasoline dispensers. The systems allow vapor
to be released into the surrounding environment. The recovery
system will accumulate vapor; turn it into liquid and re-establish
it as fuel and within the tank collecting the lowest grade
